At the median pair the signal clears the noise near ~70 swaps per epoch; a small integration's median is 4. The median epoch-volume CV is 1.54 against a 1 bps step worth ~33% of the fee rate, so most of the measured swing is market-wide activity, not a response to the floor. A ±1 bps step is also too small for the volume response to stand out at all. This MR reworks how the controller measures and moves: - it waits for enough flow before deciding, but never longer than ~7 days; - it measures fee revenue against other swappers' volume; - it finds the fee with a bracket search before handing off to the ±1 controller; - it adds a global (per-thorname) mode and resets on any whitelist change. ## What ### Measurement **1. Liquidity gate with a time cap.** A span seals a decision only once it holds `L1DynamicFeeMinSwaps` swaps (default 30) **and** `L1DynamicFeeMinVolumeUSD` of affiliate volume (default $100,000). - Below the gate, the span rolls into the next epoch, but only until it has run `L1DynamicFeeMaxEpochBlocks` (default 100,800 blocks, ~7 days). The next epoch boundary then seals it with whatever it has. - A span with no affiliate swaps at all is sealed empty at the cap, which reads as zero revenue. A fee too high to attract any flow is therefore moved off rather than held. An empty seal does not count as activity, so an idle record is still pruned after 30 epochs. - A span sealed by the cap below the gate (or empty) is marked `capped`: it is too thin to justify a higher fee, so it **may lower the fee but never raise it**. In the search a capped probe counts as tested but never displaces a lower-fee best; in the ±1 controller a raise becomes `capped_hold` and a cold start probes down. - Sealing iterates records rather than accumulators, so a record that drew no swaps is still visited. - A stream counts once, on its first *successful* sub-swap (`isFirstSuccessfulSubSwap`). Counting on `Count == 0` missed streams whose first attempt failed, which includes most resting limit orders. **2. Signal = fees / other swappers' volume.** The controller compares `fees_tor / (pool_volume_tor − own_pool_volume_tor)`: fee revenue against the volume the *rest of the market* put through the same pools over the same span. - A pair-scoped `DynamicFeePoolAccumulator` counts every swap's volume through the pair, affiliate or not. - The thorname's own volume is excluded because, when it is most of a pair's flow, dividing by the whole pool makes the ratio approach the fee rate itself, which always reads higher at a higher fee. In simulation, a 90%-share integrator whose revenue peaks at 7 bps settled near 15. - An epoch where other flow is under `L1DynamicFeeMinOtherFlowBPS` (default 10%) of the pool is recorded but not used as a measurement. - Pool volume is folded every epoch for every enrolled record, swaps or not, so a span's denominator also covers idle epochs before the thorname's first swap. Without that, a fee that delays flow would shrink the denominator and read as a higher signal. - Spans vary in length, and the ratio is comparable across them because numerator and denominator cover the same span. A per-block revenue rate was considered and rejected: it would let market-wide swings back in. ### Movement **3. Bracket search, then ±1.** A new record (or a reset one) searches `[floor, ceiling]` in large jumps rather than ±1 steps. - It tests its starting bps, then the ceiling, then the midpoint, then keeps halving the larger untested gap beside the best value: 1 → 20 → 10 → … on defaults, ~7–9 tests on `[1, 20]`. - A higher fee only wins when it beats the best by more than `L1DynamicFeeDeadbandBPS`, so near-ties keep the lower fee. - Each test holds for `L1DynamicFeeProbeEpochs` sealed spans (default 1). - On convergence the record clears its history and hands off to the existing ±step controller at the best value. - Records that exist at the upgrade search from their current `dynamic_bps`. **4. Ceiling cold start probes down.** After convergence the ±step controller cold-starts. A record at the ceiling used to cold-start in place forever: the clamped probe recorded no bps change, so it never got a move to evaluate. It now probes down when it cannot probe up. ### Modes and selection **5. Whitelist value selects the mode.** | Value | Mode | | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ | | `1` | per-pair (as before) | | `2` | **global**: one `*\|*` record per thorname, credited by every L1 swap, applied on every L1 pair, measured on the pools it actually traded | | `3` / `4` | per-pair / global **monitor**: history collected, no search or step, swaps pay the static minimum; queries show `phase: "monitor"` | | other | not enrolled | - Monitor moves off `2`; no mainnet thorname holds `2` today. - In global mode, a multi-leg swap counts its swap and volume once (first leg) and every leg's fees and own volume. - Global volume is scoped to the pairs the thorname traded, because a spike on an unrelated pair would otherwise read as a revenue collapse. **6. Reset on whitelist change.** Any change to a thorname's effective `DYNAMICFEE-WHITELIST-*` value deletes all its records and accumulators in the mimir handler, immediately: enabling it, switching mode, entering or leaving monitor, or removing it. Its next swap starts a fresh record at the floor and a fresh search. To reset a stuck thorname without changing mode, vote it to `0`, then back. **7. Only the largest affiliate counts.** In a multi-affiliate memo, only the affiliate with the largest affiliate bps is considered (first wins a tie). - In state `1`/`2` it is charged its floor and credited. - In `3`/`4` it is credited but the swap pays the static minimum. - Otherwise the swap pays the static minimum and nothing is credited. - A smaller enrolled affiliate never stands in. The thorname that sets a fee is always the one whose record measures it. - **Trade-off:** an integrator can list a non-enrolled affiliate (even its own address) at a higher bps to opt out of a dynamic floor above the static minimum. The curated whitelist is the control. This is flagged in the ADR and in a `ponytail:` comment. ## Upgrade `Migrate20to21` (consensus version 20 → 21): - deletes every in-flight thorname accumulator at the upgrade height. An accumulator straddling the upgrade would carry a full epoch of fees but only post-upgrade pool volume. - sets every record's `span_start_height` to the upgrade height, so the 7-day cap counts from the upgrade. History written before pool volume was tracked holds raw fee levels and is dropped at the first post-upgrade seal. Records keep their `dynamic_bps` and start a search from it. New fields read as zero or empty on older rows. ## Surface - **New mimirs:** - `L1DynamicFeeMinSwaps` (30), `L1DynamicFeeMinVolumeUSD` ($100,000) - `L1DynamicFeeMaxEpochBlocks` (100,800) - `L1DynamicFeeMinOtherFlowBPS` (1,000) - `L1DynamicFeeProbeEpochs` (1) - **State:** - records: `search_done`, `probes`, `span_start_height`, `pairs` - epoch records: `swap_count`, `pool_volume_tor`, `own_pool_volume_tor`, `blocks`, `capped` - probes: `capped` - accumulators: `swap_count`, `pool_volume_tor`, `own_pool_volume_tor`, `pairs` - new `DynamicFeePoolAccumulator` store (`dynfeepoolacc/`); genesis field 51 with `omitempty`, so other suites' export fixtures do not churn - **Queries:** - `phase` (`search` / `track` / `monitor`) on both record endpoints - `probes` per pair on `/thorchain/dynamic_l1_fees/{thorname}` - `swap_count`, `pool_volume_tor`, `own_pool_volume_tor`, `blocks` and `capped` on history entries, and `capped` on probes - `span_blocks` and the volume fields on `/thorchain/dynamic_l1_fees_current` - a global record's pair is `*|*` - **Event `dynamic_l1_fee_update`:** - new reasons `search_probe`, `search_converged` and `capped_hold` - new attributes `swap_count`, `pool_volume_tor`, `blocks`, `capped` - `fees_before` / `fees_after` are now normalized signals, not TOR fee levels (names kept for existing consumers) - **Manager interface:** `CreditSwapLeg` replaces `CreditSwap`, which remains as the single-leg form on the concrete type. ## Known limits - Protocol-internal swaps that call `swap()` directly (POL, affiliate-fee conversion) bypass the swap-completion hook and are excluded from pool volume. Arguably correct for a market-activity denominator; marked with a `ponytail:` comment. - The search assumes revenue is unimodal in bps and discards a losing side for good. The ±1 controller and the reset are the fallbacks. - A full search takes ~7–9 sealed spans. With the gate, each span is at least one epoch (~1 day) and at most ~7 days. ## Testing - **Unit (`go test -tags=mocknet ./x/thorchain/...`):** green. Every line this branch changes in `x/thorchain` is covered except three unreachable guards (a genesis-import panic on a setter that never errors, migration registration, and the shared `LoadManagerIfNecessary` guard). Fault-injection tests wrap the keeper and codec to exercise store and unmarshal failures. Highlights: - the search converging on a unimodal curve (1, 20, 10, 15, 12, 17, 13, 14, 16 → 15); - a 90%-share integrator converging near its revenue peak; - holding without outside flow; - global multi-leg counting and scoped pool volume; - monitor history-only; - the largest-affiliate rule across seven memo shapes; - the mimir-handler reset; - the ceiling cold start; - the span cap (roll then seal, empty seal as zero revenue, no activity bump, monitor never sealed empty); - idle epochs' pool volume carried into the span's denominator; - capped readings only lowering the fee, in the search and the ±1 controller. - **Regression:** new suite `dynamic-fee/search-modes-reset` on a mainnet-depth USDC pool, with an affiliate swap and an equal plain swap every epoch. It covers: - the per-pair search (1, 8, 4, 6, 7 → 8); - hand-off and the step down from the ceiling; - the largest-affiliate rule; - a sub-gate span rolling, being sealed at a 15-block cap with its idle epoch's pool volume, and stepping the fee down rather than up; - the global switch wiping state, and the global floor charged on a never-traded pair; - global monitor; - removal. All 193 suites pass locally; no other suite's fixtures change. - golangci-lint (repo config), markdownlint and prettier: clean. Docs: ADR-026 (changelog, design, migration, REST), `docs/mimir.md`, `docs/concepts/fees.md`, and a note in the affiliate guide to give the enrolled THORName the largest split. 🤖 Generated with [Claude Code](https://claude.com/claude-code) ``` ## What changed (AI summary) - **Why**: Controller stepped on noise: ~4 swaps/epoch vs ~70 needed. - **Liquidity gate**: Seal only with enough data; cap rolling at ~7 days. - **Signal**: Revenue measured against everyone else's volume. - **Bracket search**: Big jumps first, then ±1 tracking. - **Modes + reset**: Whitelist value picks the mode. - **Accounting fixes**: Counting and attribution bugs. ## State and upgrade (AI summary) - Migration v21 -> v22: Clears in-flight dynamic-fee accumulators; sets every record's span_start_height to the upgrade height.

O(records), collect-then-mutate. ## Checked and fine (AI) - Prefix iterators only, collected before writes; no map iteration - No floats or wall-clock time; Uint fixed-point at 1e12 - Signal guards zero pool volume and own ≥ pool - Pairs kept sorted and unique; one probe per bps - Proto fields append-only; genesis field 51 omitempty ## Explainer narration (AI) ### Intro This branch reworks THORChain's dynamic L1 swap fee: the per-affiliate fee floor from ADR-026. Here is what was wrong with it, and the five things that changed. ### Recap: ADR-026 A quick recap. Every L1 swap pays a minimum fee, set network-wide by L1SlipMinBPS. ADR-026 gives each whitelisted thorname its own floor, per trading pair. Once a day, at each epoch boundary, a controller compares fee revenue before and after the last change, and nudges the floor one basis point in whichever direction earned more. ### The problem On mainnet, that controller was stepping on noise. A small integration saw a median of four swaps per epoch. Telling a one basis point change apart from random variation needs about seventy. And day-to-day volume swung far more than the effect being measured. Most of the movement was the market, not the fee. ### Fix 1 · Liquidity gate The first fix is a liquidity gate. A measurement only counts once it holds at least thirty swaps and one hundred thousand dollars of affiliate volume. Until then, the span rolls into the next epoch, and the floor does not move. Spans are capped at about seven days. A span sealed by the cap is marked capped. It is too thin to justify a higher fee, so it may only lower one. A span with no swaps at all reads as zero revenue, so a fee too high to attract anyone is moved off, not held. ### Fix 2 · A signal that means something The second fix is a better signal. Raw fee totals mostly track market activity. Dividing by the affiliate's own volume fails too. Because the floor binds, that ratio is just the fee rate, and it always says go higher. Dividing by the whole pool is closer, but when one integrator is most of the pool, it collapses to the same thing. In simulation, an integrator with ninety percent share, whose revenue peaked at seven basis points, settled near fifteen. So the signal is fees over other swappers' volume, in the same span. An epoch where outside flow is under ten percent of the pool is recorded, but not used. ### Fix 3 · Bracket search The third fix is a bracket search. One basis point steps are too small to see, so a new record first searches the whole range in big jumps. It measures its starting fee, then the ceiling, then the midpoint, then keeps testing the middle of the larger untested gap next to the best fee so far. A higher fee only becomes the best if it wins by more than the ten percent deadband, so near-ties keep the cheaper fee. On a one to twenty range, it converges in about seven to nine tests, then hands off to the one-step controller, which follows drift from there. ### Fix 4 · Modes and reset The fourth fix is modes, picked by the whitelist mimir value. One is per-pair, as before. Two is new: global mode, a single floor for the thorname across all its L1 pairs. Pooling thin pairs clears the liquidity gate far sooner. Three and four are monitor modes for each. History is collected, but nothing is searched, and swaps pay the static minimum. Any change to the value wipes that thorname's state in the same block, so it starts a fresh search. To unstick a record, vote it to zero and back. ### Fix 5 · Attribution and accounting The fifth fix is a set of accounting fixes. A streaming swap or limit order now counts as one swap on its first successful fill, instead of never counting when its first attempt failed. In global mode, the two legs of a double swap count once toward the gate. Only the memo affiliate with the largest fee share is charged and credited. Pool volume from idle epochs is folded into the span, so a fee that delays flow cannot read as a stronger signal. And migration twenty-one to twenty-two clears in-flight accumulators at the upgrade, so no epoch mixes old fees with new volume. ### Visibility and tests The queries now expose each record's phase, its search probes, span lengths, other-flow volume, and capped readings. A new regression suite drives the whole flow on a mainnet-depth pool: the search converging, the gate rolling, the span cap, global mode, monitor, and reset. And fault-injection tests run every new error path in the store. ### In short In short: wait for enough data, measure fees against everyone else, search in big jumps, then track. These are the new defaults, all adjustable by mimir. ## Line-by-line walkthrough (AI) Each step: the head lines it covers, its flag if any, and what the narration says. ### Whitelist states: x/thorchain/types/type_dynamic_fee.go - L3-11: The types file gains a sort import for pair lists, and the common package for safe division. - L15-29 [verify: 2 was monitor-only, now charges]: The whitelist mimir now has four enrolled values. One and two charge a dynamic floor, per pair or globally; three and four run the same controllers in monitor mode, without charging. - L31-34: Global mode stores its record under a star pair key, so it shares the per-pair key space and cleanup. - L36-46: Two helpers name the ranges: valid means one through four, global means two or four. - L48-52: The signal is a ratio around ten to the minus five, so it is scaled by ten to the twelve to keep precision in integers. ### Who owns the fee: x/thorchain/manager_dynamic_fee_current.go (dominantAffiliate) - L52-59: The old selector skipped ineligible affiliates before picking the largest. Now the largest affiliate owns the fee outright. - L60-62 [careful: opt-out by bigger affiliate]: The comment calls out the trade-off: an integrator can list a bigger, non-enrolled affiliate to opt out of a high dynamic floor. - L64-69: dominantAffiliate now returns the whitelist state alongside the name, and drops the allowed-states argument. - L70-80: The loop compares bps only. The empty-name, registry and whitelist checks that used to filter inside it are gone. - L81-85: Only the winner is checked: it must be a non-empty registered thorname, and its state comes back to the caller. - L88-96: dynamicFeeRecordPair maps a global state onto the star pair, and leaves per-pair keys unchanged. ### Crediting a swap leg: x/thorchain/manager_dynamic_fee_current.go (CreditSwapLeg) - L98-110: CreditSwap gains a count-as-swap flag, so a thirty-interval streaming swap counts as one swap, and becomes a thin wrapper. - L112-120: CreditSwapLeg is the real entry point. Every leg adds to the thorname's own pool volume; only legs marked count-volume add affiliate volume. - L121-129: Disabled feature or non-L1 pairs now return false, since the function reports whether it credited a global record. - L131-137: Any enrolled state accumulates, including monitor. The leg's real pair is kept, then the record key is mapped for global mode. - L139-159: The lazy record creation is unchanged, except that a new record also stamps its span start height. - L161-168: Accumulators written before this upgrade have a nil own-pool-volume, so it is zeroed before use. - L169-176: Own pool volume always grows, affiliate volume only when asked, and the swap count only on the counted leg. - L177-185: A global accumulator also records which pair it traded, and the function returns whether this was a global credit. ### Pool volume: x/thorchain/manager_dynamic_fee_current.go (creditDynamicFeeForLegs) - L187-191: CreditPoolVolume is new: every swap through an L1 pair adds to a pair-wide accumulator, affiliate or not. - L192-209: It applies the same enabled and L1 checks, then adds the volume. Errors are logged, not returned, so a swap never fails here. - L220: creditDynamicFeeForLegs takes the count-as-swap flag, and no longer returns early when there are no affiliates. - L226-229: A flag tracks whether a global record was already credited by an earlier leg of this swap. - L247-260: Pool volume is credited first, for every leg. That ordering guarantees any sealed epoch with fees also has pool volume. - L255-259 [careful: POL excluded from denominator]: Protocol swaps that call swap directly, like POL, skip this handler and are left out of the denominator. - L261-268: Without affiliates the loop moves on. Otherwise the first leg carries volume and count, and later legs of a global swap add only fees. ### Counting user swaps: x/thorchain/handler_swap.go (isFirstSuccessfulSubSwap) - L447-450: The swap handler passes whether this is the first successful sub-swap, so a streaming swap counts once. - L549-555: The comment explains why: failed attempts still bump the count, so the test is that every earlier attempt failed. - L556-559 [verify: pre-increment count]: Legacy streaming swaps read the keeper's streaming record: first success when failed swaps equal the attempt count. - L560-564: Everything else reads the message state; with no state at all it is a plain swap, and counts. ### Charging the floor: x/thorchain/manager_dynamic_fee_current.go (GetDynamicBps) - L282-287: Only states one and two charge. Monitor states fall through to zero, which means the static minimum applies. - L288: A global thorname reads its single star record, whatever pair the swap is on. - L290-298: The rest is unchanged: a missing record charges the floor, otherwise the record's current bps. ### Normalized signal: x/thorchain/types/type_dynamic_fee.go (NormalizedSignal) - L72-82: The old LastBpsChangeIndex helper on the record is deleted; the manager keeps its own version. - L83-94: New accumulators zero all four amounts, including the two new pool volume fields. - L95-106: AddPair keeps a sorted, unique list of traded pairs, with a binary search insert, so state stays deterministic. - L108-118: The pool accumulator gets its key and constructor; it is keyed by pair alone. - L120-133: The signal is fees divided by other swappers' volume. Dividing by total volume would let a dominant integrator read a higher fee as better, always. - L134-144: No pool volume, or own volume at or above the pool's, means the epoch cannot be measured. - L145-149: If other flow is below the min-other share, there's no outside reference either. Otherwise fees times ten to the twelve over other volume. - L152-167: Probes sum signals per bps and count epochs; the mean guards zero epochs and a nil sum. ### Epoch boundary: x/thorchain/manager_dynamic_fee_current.go (EndBlock) - L302-310: When the feature is off, end block now clears pool accumulators too, so a re-enable starts clean. - L344-347: Two gate settings are read: minimum swaps, and minimum volume in whole dollars, widened to TOR precision in a Uint so it cannot overflow. - L348-360: All controller settings travel in one params struct. Probe epochs are forced to at least one. - L362-375: Sealing now iterates records, not accumulators, so a record with no swaps can still be sealed once its span hits the cap. - L377-381: Each record goes through end epoch for record. Errors are logged per record and never halt the block. - L383-390: After every record has folded in this epoch's pool volume, the pool accumulators are cleared. The pruning pass then reuses the iterator variable. - L409-417: Pruning a stale record now also deletes its accumulator, which may hold volume only. - L1026-1045: clearPoolAccumulators collects first, then deletes, so the store is never mutated under its own iterator. ### Seal, roll or wait: x/thorchain/manager_dynamic_fee_current.go (endEpochForRecord) - L422-435: The old seal signature goes, replaced by a params struct read once per epoch boundary. It adds the gate, probe and cap settings. A max span of zero or less disables the cap. - L437-448: The rule: seal when the span clears the liquidity gate, or when it has run the max span. Otherwise roll the epoch into the next one. - L449-454: Records whose thorname left the whitelist are skipped, and monitor states are noted. - L456-467: Old accumulator rows get their nil amounts zeroed, then has-swaps checks for any count, volume or fees. - L469-477: Records from before span tracking start their span now. Span length and whether it hit the cap come from block heights. - L479-501: Every epoch, swaps or not, this epoch's pool volume is folded in. Global records sum only the pairs their thorname traded. - L503-509: No swaps yet and not capped: carry the volume forward. A monitor record never seals an empty span. - L511-523: Below either gate and under the cap, the span rolls. The record is marked active so pruning cannot delete it mid-roll. - L525-528 [careful: thin passed as capped]: Otherwise seal, then delete the accumulator. Note the thin flag is passed as the seal's capped argument. ### Sealing a span: x/thorchain/manager_dynamic_fee_current.go (sealEpochForRecord) - L531-538: Seal now takes the record and accumulator directly, plus span length, capped, has-swaps and monitor. - L539-546: History written before pool volume existed is dropped on every seal; those raw fee levels can't be compared with the ratio. - L554-564: Each history entry now stores swap count, both pool volumes, span blocks and the capped flag. - L565-571: Only spans with swaps mark the record active, so a thorname that stops trading still gets pruned. - L573-578: Monitor records save history and stop. They never search or step, because their swaps pay the static fee anyway. - L580-589: Until the search converges, search step chooses the next bps. After that, the gradient rule takes over. - L595-611: The update event fires on any bps change, and also on convergence, now carrying swap count, pool volume, blocks and capped. ### Gradient rules: x/thorchain/manager_dynamic_fee_current.go (decideNextBps) - L624-635: The doc adds two rules: a cold start at the ceiling probes down, and a capped span may only lower the fee. - L636-645: decideNextBps wraps the old rule. If the newest entry is capped and the rule wants to raise, it holds instead, or probes down on a cold start. - L647-659: At the ceiling a cold start probe up would clamp to no change, and stay stuck forever, so it steps down instead. - L661-666: Before and after windows now average normalized signals instead of raw fees. ### Bracket search step: x/thorchain/manager_dynamic_fee_current.go (searchStep) - L697-707: Search step runs once per sealed span until the record converges on its best fee. - L708-719: If the latest entry has no usable signal, it holds at the same bps and measures again. - L721-729: The signal is credited to the probe for the current bps, creating it if needed. A capped span marks the probe capped. - L730-734: Until the probe has enough epochs, keep measuring at this bps. - L736-739: Then ask next search bps for the best probe so far, and the next value to test. - L740-745: On convergence the record switches to the gradient controller at the best bps, with history cleared so the jumps aren't misread as steps. ### Choosing the next probe: x/thorchain/manager_dynamic_fee_current.go (nextSearchBps) - L748-764: Next search bps assumes revenue has one peak, so the optimum sits between the best probe and its nearest tested neighbours. - L765-782: Only measured probes inside the current floor and ceiling count. If none do, the search restarts at the floor. - L784-797: A higher fee only wins if it beats the best by more than the deadband, in integers. Capped probes never win. - L799-811: It finds the nearest tested values below and above best, by value, so duplicate bps can't underflow the gap maths. - L813-823: Each side's gap counts untested values. An untested floor or ceiling is tested before any midpoint. - L825-833: Both gaps empty means done. Otherwise test the larger gap, with ties going to the lower side. ### Signals and means: x/thorchain/manager_dynamic_fee_current.go - L835-854: Global records sum this epoch's pool volume across the pairs they traded. Malformed keys are skipped and errors logged. - L873-892: Window signals replaces the old fee mean: it returns each entry's normalized signal, skipping entries that can't be normalized. - L894-905: Mean signal averages them, and an empty window reads as zero, which the gradient treats as hold. ### Whitelist change resets: x/thorchain/handler_mimir.go - L193-197: Any change to a thorname's whitelist mimir now restarts its dynamic fee from scratch, and that is also the documented way to unstick one. - L198-202 [careful: any re-vote wipes history]: The key prefix is matched case-insensitively, and all records and accumulators for that thorname are deleted. Failures are logged. ### New defaults: constants/constants_v1.go - L173-174: Deadband and window comments now describe the normalized signal. - L175-176: The liquidity gate defaults to thirty swaps and a hundred thousand dollars of affiliate volume. - L177-178: One epoch per probe, and at least ten percent of a pair's volume must come from other swappers. - L179: The max span is one hundred thousand eight hundred blocks, about seven days, before a thin span seals anyway. ### Upgrade migration: x/thorchain/migrations_common.go (Migrate21to22) - L525-536: The migration exists because an accumulator straddling the upgrade has a full epoch of fees but only part of the pool volume. - L537-562: It loads the managers, collects every in-flight accumulator, then deletes them. An unmarshal error aborts the upgrade. - L564-565: Pool accumulators ship with this upgrade, so there's nothing to clear there. - L567-586: Every record's span starts at the upgrade height, so the seven-day cap counts from here. - L588-590: It logs how many accumulators it cleared. - L537 [careful: renumbered after develop's 20→21]: It is registered as migrate twenty one to twenty two, because develop already uses twenty to twenty one. Re-check the number if develop bumps again before merge. ### Keeper and plumbing (skim: x/thorchain/keeper/v1/keeper_dynamic_fee.go, x/thorchain/keeper/keeper.go, x/thorchain/keeper/v1/keeper.go, x/thorchain/keeper/keeper_dummy.go, x/thorchain/managers.go, x/thorchain/module.go, constants/constant_values.go) The keeper gets get, set, delete and iterate for the pool accumulator under a new prefix, and the whitelist cleanup accepts states one through four. The interface, dummy keeper and manager interface follow, and the consensus version goes to twenty two. Five new constants are declared for the gate, probe, other-flow and span settings. ### Aliases (skim: x/thorchain/keeper/alias.go, x/thorchain/keeper/v1/alias.go) The alias files re-export the new types and constants; most of these lines are re-alignment, not new logic. ### Genesis and queries (skim: x/thorchain/genesis.go, x/thorchain/querier_dynamic_fee.go) Genesis imports and exports the pool accumulators; most of its other lines are re-alignment. The queries add a phase of search, track or monitor, the probes, and the new per-epoch fields. The current-epoch query also shows the swap count, pool volume and span length so far, which answers why the controller hasn't moved yet. ### Proto (skim: proto/thorchain/v1/types/type_dynamic_fee.proto, proto/thorchain/v1/types/query_dynamic_fee.proto, proto/thorchain/v1/thorchain/genesis.proto) The protos add the fields you have seen in the code: span heights, pool volumes, probes, pairs and the search flag, all as new field numbers. ## Glossary (AI) - **ADR-026**: The design record for the dynamic L1 minimum fee per thorname. This MR reworks its controller: liquidity gate, normalized signal, bracket search and modes. [ADR-026](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/docs/architecture/adr-026-dynamic-l1-min-fee-per-thorname.md) - **Affiliate**: The integrator credited with a swap's affiliate fee. The controller attributes a swap to the largest affiliate only. [affiliate fee guide](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/docs/affiliate-guide/affiliate-fee-guide.md) - **bps**: Basis points: one hundredth of a percent. The dynamic floor moves between 1 and 20 bps. - **Bracket search**: How the controller picks the next bps to probe: big jumps first, then the midpoint of the best bracket, until neighbours are tested. [manager_dynamic_fee_current.go](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/x/thorchain/manager_dynamic_fee_current.go) - **Epoch / span**: An epoch is the controller's measurement interval. A span is the run of epochs rolled together until the liquidity gate or the ~7-day cap seals it. [constants_v1.go](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/constants/constants_v1.go) - **Liquidity gate**: A span seals only with at least 30 swaps and $100k of affiliate volume; below that it rolls into the next epoch. [manager_dynamic_fee_current.go](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/x/thorchain/manager_dynamic_fee_current.go) - **Mimir**: Node-voted runtime settings that override protocol constants. Here they tune the controller and enrol thornames via the whitelist key. [docs/mimir.md](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/docs/mimir.md) - **POL**: Protocol-owned liquidity. Its volume is left out of the signal's denominator. [ADR-006](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/docs/architecture/adr-006-enable-pol.md) - **Streaming swap**: A swap executed in sub-swaps over several blocks. This MR counts it as one swap for the liquidity gate. [streaming swaps](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/docs/swap-guide/streaming-swaps.md) [ADR-010](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/docs/architecture/adr-010-streaming-swaps.md) - **Thorname**: A registered THORChain name that integrators use as their affiliate. Each enrolled thorname gets its own dynamic fee records and accumulators. [thorname guide](https://gitlab.com/thorchain/thornode/-/blob/c9d58dd20ce282595482260855666bcf9e3737e3/docs/affiliate-guide/thorname-guide.md) ## Diff `git diff bd0ac8ca0942...c9d58dd20ce2`, generated files and test fixtures left out. ### constants/constant_values.go (Logic, +5 -0) ```diff diff --git a/constants/constant_values.go b/constants/constant_values.go index c7bc19fb52..173808bac2 100644 --- a/constants/constant_values.go +++ b/constants/constant_values.go @@ -206,6 +206,11 @@ const ( L1DynamicFeeStepBPS L1DynamicFeeDeadbandBPS L1DynamicFeeWindowEpochs + L1DynamicFeeMinSwaps + L1DynamicFeeMinVolumeUSD + L1DynamicFeeProbeEpochs + L1DynamicFeeMinOtherFlowBPS + L1DynamicFeeMaxEpochBlocks VaultDeficitGasHaltMaxGasMultiplier BondYieldEnabled ``` ### constants/constants_v1.go (Logic, +7 -2) ```diff diff --git a/constants/constants_v1.go b/constants/constants_v1.go index 97a9a39f99..08b193000d 100644 --- a/constants/constants_v1.go +++ b/constants/constants_v1.go @@ -170,8 +170,13 @@ func NewConstantValue() *ConstantVals { L1DynamicFeeFloorBPS: 1, // floor basis points for dynamic L1 min fee L1DynamicFeeCeilingBPS: 20, // ceiling basis points for dynamic L1 min fee L1DynamicFeeStepBPS: 1, // step basis points for dynamic L1 min fee adjustment - L1DynamicFeeDeadbandBPS: 1000, // % change in fees_rune (in bps, 10000 = 100%) below which the dynamic L1 fee controller holds - L1DynamicFeeWindowEpochs: 3, // epochs averaged on each side of the last bps change when measuring the fees_rune gradient (clamped into [1, MaxDynamicFeeHistory]) + L1DynamicFeeDeadbandBPS: 1000, // % change in the normalized fee signal (in bps, 10000 = 100%) below which the dynamic L1 fee controller holds + L1DynamicFeeWindowEpochs: 3, // epochs averaged on each side of the last bps change when measuring the fee-signal gradient (clamped into [1, MaxDynamicFeeHistory]) + L1DynamicFeeMinSwaps: 30, // swaps a dynamic fee epoch must contain before it may seal a decision;

Dividing by the whole pool made the + ratio approach the fee rate itself whenever the thorname was most + of a pair's flow, which always reads higher at a higher fee; a + 90%-share integrator whose revenue peaks at 7 bps settled near 15. + An epoch whose other flow is under `L1DynamicFeeMinOtherFlowBPS` + (default 10%) of the pool is recorded but is not a measurement. + 2. **A time cap on measurement spans.** A span below the liquidity + gate (`L1DynamicFeeMinSwaps` swaps _and_ `L1DynamicFeeMinVolumeUSD` + of affiliate volume, the latter now defaulting to $100,000) rolls + into the next epoch, but only until it has run + `L1DynamicFeeMaxEpochBlocks` (default 100,800 blocks, about 7 + days). The next epoch boundary then seals it with what it has. A + span with no swaps at all is sealed empty, which reads as zero + revenue. Either way, a fee so high that it cannot attract the + gate's volume is measured and moved off rather than held there. + Spans therefore vary in length; they stay comparable because the + signal divides fees by other swappers' volume over the same span + (a revenue rate per block would let market-wide swings back in). + Each entry records its length in `blocks`. A span sealed by the cap + below the gate is marked `capped`: too thin to justify a higher fee, + it may only lower it. In the search a capped probe never displaces a + lower-fee best (it still counts as tested); in the ±step controller + a raise on a capped reading becomes `capped_hold` and a cold start + probes down. + 3. **Global mode is measured on the pairs it trades.** A global + accumulator records the pairs it was credited on, and its pool + volume sums only those pairs, so volume on unrelated pairs no + longer moves its signal. + 4. **Monitor records collect history only.** Their swaps pay the + static minimum, so a search or step would measure noise. Monitor + records never search or step; queries show `phase: "monitor"`. + 5. **The fee and the credit go to the same affiliate**, which is also + the multi-affiliate rule: only the memo affiliate with the largest + affiliate bps counts. It is charged its floor when its state is + `1`/`2` and credited when it is `1`-`4`; otherwise the swap pays + the static minimum and nothing is credited. A smaller affiliate + never stands in for it. + + Adds `own_pool_volume_tor` to epoch records, accumulators and both + query endpoints, `blocks` to epoch records and history entries, + `span_start_height` and `pairs` to records, `pairs` to accumulators, + and `span_blocks` to the in-progress query. + +- 2026-10-19: **Bracket search, global mode, reset on change.** Three + changes: + + 1. **Bracket search.** A ±1 bps step moves the floor too little for + the volume response to stand out from noise, so a record now + starts by searching `[floor, ceiling]` in large jumps: it measures + its starting bps, then the ceiling, then the midpoint, then keeps + halving the gap next to the best value measured so far (1 → 20 → + 10 → … on defaults; about 7-9 tests to converge on `[1, 20]`). + Each test holds for `L1DynamicFeeProbeEpochs` sealed (gated) + epochs, default 1. Once the gaps beside the best value are empty + the record hands off to the existing ±step controller at that + value, which follows drift from there. See "Search rule" below. + 2. **Global mode.** The whitelist value now also selects the mode: + `1` = per-pair (unchanged), `2` = global — one floor per thorname, + tuned on all its L1 pairs together and applied on every L1 pair. + Global mode pools a thorname's thin pairs into one signal, so it + clears the liquidity gate far sooner. Monitor mode moves from `2` + to `3` (per-pair) and `4` (global). No mainnet thorname used `2`. + 3. **Reset on change.** Any change to a thorname's effective + `DYNAMICFEE-WHITELIST-{thorname}` value — enabling it, switching + mode, entering or leaving monitor, or removing it — immediately + deletes all of its dynamic-fee state, so it rediscovers its floor + from scratch. This is also how to unstick a record: vote it to + `0`, then back. + + The ±step controller's cold-start probe goes down instead of up when + the record is already at the ceiling, so a search that converges on + the ceiling still has its next move evaluated rather than sitting + there until a reset. + + Adds `search_done` and `probes` to records, `phase` to both REST + record endpoints, and `probes` to the per-thorname endpoint. Records + that exist at the upgrade keep their current `dynamic_bps` and start + a search from it. + +- 2026-09-19: **Noise reduction.** Two changes, driven by live data from + a small integration whose epochs held a median of 4 swaps against a + noise-crossover near 70: + + 1. **Liquidity gate.** An epoch must hold at least + `L1DynamicFeeMinSwaps` swaps _and_ `L1DynamicFeeMinVolumeUSD` of + affiliate volume before it may seal a decision. Otherwise the + accumulator rolls into the next epoch, unbounded, and the floor + does not move. Streaming swaps count once, not once per + sub-swap. An integration that never clears the gate simply never + steps, which is the correct behaviour at that size. + 2. **Pool-volume normalization.** The gradient now compares + `fees_tor / pool_volume_tor` — the affiliate's fee revenue as a + share of the pool's _total_ volume over the same span — rather + than raw fee levels. Most of the previously-measured swing was + market-wide activity, not a response to the floor. Note the + denominator is deliberately the _pool's_ volume and not the + affiliate's own `volume_tor`: because the floor binds, the latter + ratio is identically `f / 10⁴`, which would read `continue_up` + every epoch and pin the ceiling while carrying zero elasticity + information. + + Adds pair-scoped `DynamicFeePoolAccumulator` state, `swap_count` and + `pool_volume_tor` to epoch records, accumulators and both query + endpoints. History written before this change carries raw fee levels + in incompatible units and is dropped at the first post-upgrade seal; + affected records keep their current `dynamic_bps` and re-enter + cold start. Store migration `Migrate21to22` clears the in-flight + accumulators so no sealed entry mixes a full epoch of fees with a + partial epoch of pool volume (see "Migration" below). + - 2026-07-22: Status moved to Implemented — the feature is live on mainnet (`L1DynamicFeeEnabled = 1`). - 2026-04-27: Switch the gradient signal from `fees_rune` to `fees_tor` @@ -61,11 +176,15 @@ Implemented ## TL;DR Replace the single network-wide `L1SlipMinBPS` with a per-`(thorname, pair)` -dynamic floor tuned by an on-chain **closed-loop revenue gradient**.

Income up, the floor continues in the same direction; income down, it reverses. Each step is one basis point, so the floor settles higher where THORChain is the only venue and lower where it competes. See [ADR 026](../architecture/adr-026-dynamic-l1-min-fee-per-thorname.md) for the rule, bounds and events. +At the end of each epoch (~24h) the network totals the fee income that THORName produced and divides it by the volume other swappers put through the same pools over the same period (in global mode, the pools that THORName traded). Leaving out the THORName's own volume means a fee that drives its own users away shows up as lost income rather than looking like a higher rate. An epoch where other swappers are under 10% of a pool's volume is not used. A new THORName first searches the allowed range in large jumps — the lowest floor, then the highest, then the midpoint, then halving towards whichever did best — so each test changes the price enough to show up in the income. Once the search settles, the floor moves one basis point at a time: income share up after a change, it continues in the same direction; down, it reverses. The floor settles higher where THORChain is the only venue and lower where it competes. + +An epoch only decides anything if it is large enough to carry signal — at least `L1DynamicFeeMinSwaps` swaps and `L1DynamicFeeMinVolumeUSD` of volume. Thinner epochs roll into the next one and the floor does not move, but only for up to `L1DynamicFeeMaxEpochBlocks` (about seven days): after that the span is measured with whatever it has, and a span with no swaps at all counts as zero revenue, so a fee too high to attract swaps is moved off rather than held. Such a capped reading can lower the floor but never raise it. Because spans vary in length, the comparison uses fee income against other swappers' volume over the same span, which does not depend on how long the span ran. See [ADR 026](../architecture/adr-026-dynamic-l1-min-fee-per-thorname.md) for the rule, bounds and events. This only affects the liquidity fee charged to the swapper. The affiliate's own basis points and the existing fee accounting path (extraction to the Reserve, then distribution via the [Incentive Pendulum](./incentive-pendulum.md)) are unchanged.

When a memo lists several affiliates, the protocol first filters to Active enrolled THORNames that carry a non-zero affiliate fee, then selects the largest affiliate basis-point split among those remaining — that entry's floor applies. Raw addresses, expired THORNames, Monitor-mode, unenrolled, and zero-bps entries are skipped; if none remain eligible the swap uses `L1SlipMinBps`. See the [THORName guide](../affiliate-guide/thorname-guide.md) for validity and expiry rules. +A new record starts at 1 bps, so enrollment begins below `L1SlipMinBps`; the ceiling is not capped at `L1SlipMinBps`, so a THORName can be charged above it while the search tests higher fees. When a memo lists several affiliates, only the one with the largest affiliate basis-point split counts (the first listed wins a tie). If it is an enrolled THORName in state `1` or `2`, its floor applies and the swap is credited to it; if it is in a monitor state, the swap is credited to it but uses `L1SlipMinBps`; if it is a raw address, an expired or unenrolled THORName, the swap uses `L1SlipMinBps` and nothing is credited. A smaller affiliate in the memo never stands in for it. See the [THORName guide](../affiliate-guide/thorname-guide.md) for validity and expiry rules.
