feat(drive)!: make the daily withdrawal limit 15% of the total credits held a day ago - #4457

Conversation
…s held a day ago The flat daily withdrawal limit (2000 Dash since v8, 4000 Dash in the unreleased v14) is hit routinely and has to be bumped by hand as Platform grows. From v14 Platform pools at most `SystemLimits::daily_withdrawal_limit_percent` (15) of the total credits it held a day ago into asset unlock transactions per 24 hours; amounts pooled in the last 24 hours keep counting against the maximum. - rs-dpp: `daily_withdrawal_limit` v2 applies the percent to the reference total it is handed (`DPP_METHOD_VERSIONS_V3`); v1 is back to a frozen const 2000 Dash and the flat `SystemLimits::daily_withdrawal_limit` is removed. - rs-drive: a total credits history under the withdrawals root tree, keyed by block time (`WITHDRAWAL_TOTAL_CREDITS_HISTORY_KEY`), with `record_total_credits_history` (insert + bounded prune of everything older than the entry the limit reads) and `fetch_total_credits_in_platform_a_day_ago` (latest entry >= 24h old, else the oldest); `calculate_current_withdrawal_limit` v1 derives the daily maximum from that lagged total and now takes `&BlockInfo`. The tree is created at genesis for v14+ and by `transition_to_version_14`. - rs-drive-abci: `record_total_credits_history_for_withdrawals` runs every block before pooling (`DRIVE_ABCI_METHOD_VERSIONS_V10`), bounded by `DRIVE_ABCI_WITHDRAWAL_CONSTANTS_V3.total_credits_history_prune_limit`. - Tests: dpp v2 + dispatcher, drive history/lookup/limit, drive-abci event and migration, and a v14 strategy test (`..._hitting_relative_limit`) running 80 withdrawals against the 15% rule across three days.

Preliminary review — Codex only
The versioned implementation and bounded history queries are generally well structured, but three in-scope blockers remain: low balances can permanently strand valid withdrawals and block the FIFO queue, activation bootstrap bypasses the intended 24-hour inflation delay, and epoch rewards are timestamped one block late in the history. The version-table comments also incorrectly present inherited PV13 changes as the introduction of the PV14 table.
Source: gpt-5.6-sol (Codex general, security-auditor, and rust-quality reviewer lanes) and gpt-5.6-sol (final verifier); CodeRabbit inline evidence was also validated. openclaw-agent/cliproxy/gpt-5.6-sol was orchestration-only and is not reviewer evidence.
Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

- [BLOCKING] packages/rs-platform-version/src/version/system_limits/v4.rs:20-23: The relative cap can permanently strand a valid withdrawal
PV14 accepts individual withdrawals up to 500 Dash, but its daily maximum can be lower than that without any corresponding admission check. For example, a valid 400-Dash withdrawal against a 2,000-Dash reference total exceeds the 300-Dash daily maximum. Executing the transition has already removed the 400 Dash from `TOTAL_SYSTEM_CREDITS`, so without unrelated inflows the later reference total falls to 1,600 Dash and the maximum falls further to 240 Dash; the document never becomes eligible. `pool_withdrawals_into_transactions_queue_v1` also breaks when the oldest document exceeds the available limit, so this document prevents every later, smaller withdrawal from being pooled. Ensure every accepted withdrawal can eventually fit the daily maximum, support splitting, or change queue handling and admission rules so an unpoolable FIFO head cannot permanently block withdrawals.

- [BLOCKING] packages/rs-drive-abci/src/execution/engine/run_block_proposal/v0/mod.rs:356-362: History is recorded before epoch rewards change total credits
This records `TOTAL_SYSTEM_CREDITS` before `process_block_fees_and_validate_sum_trees` runs at lines 403-409. On an epoch change, that later path calls `add_distribute_fees_from_oldest_unpaid_epoch_pool_to_proposers_operations_v1`, which adds the epoch's Core rewards through `SystemOperationType::AddToSystemCredits`. The reward is therefore associated with the next block's timestamp rather than the block in which Platform received it. This produces the wrong reference total for the interval between those timestamps; after a chain halt longer than 24 hours, the pre-reward value remains eligible while the actual post-reward total is timestamped only at restart and delayed for another day. Record the final snapshot after all operations that mutate total credits have been applied. Pooling can still run before that snapshot because the empty-history fallback supplies the current total on the first activation block.
In `packages/rs-drive/src/drive/identity/withdrawals/fetch_total_credits_in_platform_a_day_ago/v0/mod.rs`:
- [BLOCKING] packages/rs-drive/src/drive/identity/withdrawals/fetch_total_credits_in_platform_a_day_ago/v0/mod.rs:36-40: Bootstrap fallback removes the 24-hour inflation delay
When no snapshot is at least 24 hours old, this uses the oldest available entry. The PV14 migration creates an empty history tree, while `run_block_proposal_v0` processes untrusted state transitions before recording the first entry. An inflation flaw exercised in the activation block therefore installs the already-inflated total as the reference immediately, defeating the guardrail's stated purpose of delaying a sudden increase for 24 hours. Inflation immediately before activation has the same result. Keep the frozen flat limit until a genuinely day-old snapshot exists, or populate historical state before activating the relative rule.
In `packages/rs-platform-version/src/version/drive_abci_versions/drive_abci_method_versions/v10.rs`:
- [SUGGESTION] packages/rs-platform-version/src/version/drive_abci_versions/drive_abci_method_versions/v10.rs:15-34: Remove the stale PV13 version-table commentary
The header says this table was introduced in protocol version 13 and describes `process_validation_result` and `record_added_balance_outputs` as its changes. Both fields already have these values in `DRIVE_ABCI_METHOD_VERSIONS_V9`; the only PV14 delta in V10 is enabling `record_total_credits_history_for_withdrawals`. The correct V10 documentation at lines 35-38 is immediately preceded by this contradictory header, and the inherited `changed` comments at lines 130-145 repeat the same ambiguity. Remove the copied V9 header and describe inherited fields as unchanged where commentary is still useful.
…, record after fees Review follow-ups for the day-lagged daily withdrawal limit: - Floor the daily maximum at `max_withdrawal_amount`: 15% of a small total could be below a single accepted withdrawal, which could then never pool and, since pooling stops at the FIFO head, blocked every withdrawal behind it. - Drop the "oldest entry" bootstrap: until a recorded total is a day old the flat 2000 Dash of the previous rule applies (`daily_withdrawal_limit` now takes the day-old total as an `Option`), so inflating the total before or at activation cannot become the base without the 24h lag. - Record the history after `process_block_fees_and_validate_sum_trees` and before the app hash, so epoch Core rewards are timestamped in the block that added them. - Remove the V9 header copied into `DRIVE_ABCI_METHOD_VERSIONS_V10` and mark the inherited v13 fields as unchanged. - Re-size the strategy test (`should_cap_withdrawals_at_the_relative_daily_limit`) to cover the flat first day and the percent rule with the floor not binding.

Preliminary review — Codex only
The four prior findings are fixed: the relative limit is floored at one maximal withdrawal, bootstrap waits for genuinely day-old history, history is recorded after epoch rewards, and the stale V10 commentary is gone. One blocking compatibility issue remains because the uncapped percentage can exceed Core V24's fixed 4000-Dash rolling-window capacity; three non-blocking versioning, documentation, and regression-test issues also remain.

In `packages/rs-dpp/src/withdrawal/daily_withdrawal_limit/v2/mod.rs`:
- [BLOCKING] packages/rs-dpp/src/withdrawal/daily_withdrawal_limit/v2/mod.rs:38-42: The relative limit can exceed Core V24's unlock capacity
This percentage is bounded only from below, so any day-old total above roughly 26,667 Dash yields more than 4000 Dash per day; the test's 30,000-Dash example already returns 4500 Dash. Core V24 independently computes `LimitAmountV24 - latelyUnlocked`, where `LimitAmountV24` is 4000 Dash and the rolling period is 576 blocks, and `CCreditPoolDiff::Unlock` rejects blocks exceeding that available amount. Core's mempool does not enforce the credit-pool capacity, so Platform can successfully broadcast transactions that miners cannot include; those documents remain BROADCASTED and Platform expires/re-signs them after 48 Core blocks, well before the 576-block window clears. Sustained Platform pooling above 4000 Dash therefore creates a growing retry backlog instead of reducing pending withdrawals. Cap the effective Platform rate to Core's active rolling-window capacity, or coordinate a Core rule with matching relative capacity before activating this behavior.
In `packages/rs-platform-version/src/version/drive_versions/drive_identity_method_versions/mod.rs`:
- [SUGGESTION] packages/rs-platform-version/src/version/drive_versions/drive_identity_method_versions/mod.rs:23-24: Represent the PV14-only history methods as optional version slots
These methods depend on the total-credits history subtree introduced in PV14, but their slots are plain `FeatureVersion`s and the V1 table used by PV1-PV13 assigns both version 0. Their public dispatchers consequently advertise the methods as active for historical protocol versions and route calls into storage paths that did not exist under those versions. Use `OptionalFeatureVersion`, set historical tables to `None`, set PV14 to `Some(0)`, and return `VersionNotActive` from the Drive dispatchers when the slot is absent.
In `packages/rs-drive-abci/src/execution/engine/run_block_proposal/v0/mod.rs`:
- [SUGGESTION] packages/rs-drive-abci/src/execution/engine/run_block_proposal/v0/mod.rs:395-413: Add a regression test for recording after epoch rewards
The corrected ordering is consensus-visible, but the added event test manually changes system credits before directly invoking the event, and the strategy test does not assert the history entry produced by an epoch-boundary block with a nonzero Core reward. Add a production-path `run_block_proposal` test that crosses an epoch boundary and verifies that the entry keyed by that block contains the post-reward total. Without that assertion, moving the event before fee processing again would pass the current tests while restoring the previously identified incorrect withdrawal base.
In `packages/rs-platform-version/src/version/drive_versions/drive_identity_method_versions/v2.rs`:
- [SUGGESTION] packages/rs-platform-version/src/version/drive_versions/drive_identity_method_versions/v2.rs:16-26: Update the identity V2 table header to include the withdrawal-limit change
The header says V2 differs from V1 in exactly one behavior-neutral query-builder flip, but line 170 also changes `calculate_current_withdrawal_limit` from 0 to 1 and selects the consensus-visible day-lagged relative rule. Version-table comments are used to audit protocol behavior, so this currently hides one of PV14's substantive changes.
…capacity Review follow-ups for the day-lagged daily withdrawal limit: - `SystemLimits::max_daily_withdrawal_amount` (4000 Dash in v14, Core's `LimitAmountV24` per 576-block window) caps the relative limit: pooling more than Core mines only cycles unlocks through expiry and re-signing. - The two PV14-only Drive history methods are `OptionalFeatureVersion` slots (`None` before v14, dispatchers return `VersionNotActive`). - Production-path regression test: the total credits history entry keyed by an epoch-change block carries the post-Core-reward total.

Final validation — Codex/Sol only (Phase 2 disabled)
The relative withdrawal cap, activation lag, PV14-only slots, and post-reward history regression are implemented correctly, and the targeted DPP and strategy tests pass. Two nonblocking issues remain: the V2 identity table header omits its substantive withdrawal/history deltas, and v2 silently violates its floor if the configured daily cap is below the maximum single withdrawal. Source: gpt-5.6-sol (Codex general, security-auditor, rust-quality, and final verifier); openclaw-agent/cliproxy/gpt-5.6-sol was orchestration-only and not reviewer evidence.
Validated zero-blocker Codex/Sol precheck evidence was promoted to final because Phase 2 (Sonnet/Opus) is temporarily disabled. This is Codex/Sol-only final validation, not Codex + Sonnet/Opus coverage.

- [SUGGESTION] packages/rs-platform-version/src/version/drive_versions/drive_identity_method_versions/v2.rs:16-26: Update the identity V2 table header to include the withdrawal-limit change
The header still says V2 differs from V1 in exactly one behavior-neutral query-builder flip. The table also changes `calculate_current_withdrawal_limit` to version 1 and activates both total-credits-history methods at lines 170–172. Those three slots select the consensus-visible day-lagged withdrawal rule and its storage support, so the current header is misleading when auditing or backporting protocol-version behavior.
In `packages/rs-dpp/src/withdrawal/daily_withdrawal_limit/v2/mod.rs`:
- [SUGGESTION] packages/rs-dpp/src/withdrawal/daily_withdrawal_limit/v2/mod.rs:40-57: Validate that the daily cap preserves the withdrawal floor
The v2 contract says its result is never below `max_withdrawal_amount`, and `SystemLimits` documents that the daily cap must be at least that floor. However, `.max(floor).min(cap)` returns `cap` whenever a supplied platform version has `max_daily_withdrawal_amount < max_withdrawal_amount`. The shipped V4 constants are coherent, but these version tables are manually assembled and `PlatformVersion` can be cloned with public fields; a contradictory snapshot would silently reintroduce an unpoolable maximal withdrawal instead of reporting corrupted configuration. Reject the mismatch explicitly and add a focused test for it.
A configured `max_daily_withdrawal_amount` below `max_withdrawal_amount` would silently let an accepted withdrawal never fit the daily maximum; report it as a corrupted configuration instead. Also document PV14's withdrawal deltas in the V2 identity-method table header. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Final validation — Codex/Sol only (Phase 2 disabled)
Both prior suggestions are fixed at the exact head: the V2 identity-method header now documents all PV14 withdrawal deltas, and the relative-limit implementation rejects a daily cap below one maximal withdrawal. The targeted DPP withdrawal-limit suite passes all 8 tests, and no remaining in-scope defects were reported or identified.

Brings the branch up to date with upstream after #4457, #4465, #4399, #4467, #4257, #4382, #4423, #4463, #4377, #4440, #4472, #4477, #4470, and #4469 landed on v4.2-dev (base tip 1e26927). One conflict, in packages/kotlin-sdk/.../dashsdk/wallet/ManagedCoreWallet.kt: upstream #4377 inserts a new setGapLimit() immediately above broadcastTransaction(), while this branch rewrites that same broadcastTransaction() — expanding its KDoc to document the age-guard refusal and wrapping the body in mapNativeErrors { } so the native stale-broadcast error (code 34) surfaces typed. The two edits are additive and independent, so resolved as the union: setGapLimit() kept verbatim from upstream, broadcastTransaction() kept verbatim from this branch. Three more files overlapped but auto-merged, and were verified rather than assumed: - changeset/core_bridge.rs: this branch factors the input walk into spent_outpoint()/spent_outpoints() so the in-broadcast fence and the persister's spent-set cannot disagree about which inputs count; upstream #4257 replaces the synthetic ScriptBuf::default() with the input's real locking script. Orthogonal — #4257 changes the Utxo payload, the fence's filter predicate is unchanged. Both sides' tests pass, including #4257's two new script-reconstruction tests running through this branch's refactored walk. - manager/mod.rs: upstream adds the tracked_masternodes field and its initializer; this branch's SpendObservationHandler registration and its cfg(any(test, feature = "shielded")) widening are untouched. - rs-platform-wallet-ffi/src/error.rs: upstream adds ErrorMasternodeListUnavailable = 46; this branch maps PlatformWalletError::StaleReservation onto the existing shared code 34. No discriminant or name collides. Upstream's three new PlatformWalletPersistence methods all carry default bodies, so this branch's NoopTestPersister needs no change. Verified: the merged tree is identical to origin/v4.2-dev except in exactly the 18 files this branch owns, and this branch's net delta against the new base is unchanged at +3457/-103. cargo test -p platform-wallet --lib: 784 passed, 0 failed. cargo test -p platform-wallet-ffi --lib: 278 passed, 0 failed. cargo fmt --check and cargo clippy --all-targets -D warnings: clean on both crates.

Issue being fixed or feature implemented
The daily withdrawal limit is a flat amount (2000 Dash since PV8, 4000 Dash in the unreleased PV14 after #4452). With the current volume of Platform → Core withdrawals the flat cap is hit routinely, transfers sit "pending" for hours, and a flat number needs a protocol bump every time Platform grows. It exists as a guardrail against an undiscovered inflation bug, so it should scale with what Platform actually holds — but lag behind it, so a sudden jump in the total cannot lift the limit immediately.
This makes the limit relative for PV14: Platform pools at most 15% of the total credits it held a day ago into asset unlock transactions per 24 hours, never below one maximal withdrawal (
max_withdrawal_amount, 500 Dash), never above Core's unlock capacity per day (max_daily_withdrawal_amount, 4000 Dash =LimitAmountV24), and with the flat 2000 Dash still applying for the first day after activation while no recorded total is a day old yet. Amounts pooled in the last 24 hours keep counting against the maximum exactly as before; only the base of the maximum changes.What was done?
Rule (
rs-dpp) —daily_withdrawal_limitv2 takes the day-old total as anOption:Some(total)→min(max(daily_withdrawal_limit_percent × total, max_withdrawal_amount), max_daily_withdrawal_amount)(percent and cap are newSystemLimitsfields,Some(15)/Some(4000 Dash)inSYSTEM_LIMITS_V4,Nonebefore; the floor guarantees every accepted withdrawal eventually fits and cannot block the FIFO pooling queue behind it; the cap is Core's credit-pool unlock capacity per day — pooling more than Core mines only cycles unlocks through expiry and re-signing — and is raised together with Core);None(no recorded total is a day old yet, i.e. the first day after activation) → the flat 2000 Dash of v1, so the 24h lag cannot be skipped by inflating the total before or at activation. v1 goes back to a frozenconst fnof 2000 Dash, since that flat value is now history and never changes again (SystemLimits::daily_withdrawal_limitfrom #4452 is removed).DPP_METHOD_VERSIONS_V3(new, PV14) selects v2.Base (
rs-drive) — Platform keeps no history of its total credits, so PV14 adds one under the withdrawals root tree (WITHDRAWAL_TOTAL_CREDITS_HISTORY_KEY = [4]): key = block time (ms, big-endian), value =TOTAL_SYSTEM_CREDITSat the end of that block's state transitions, written only when the total changed — the limit reads the entry in force a day ago and an entry describes the total until the next one, so a block that leaves the total untouched (document traffic and fees don't move it; asset locks, withdrawals and epoch core rewards do) costs one reverselimit 1read and no write.Drive::record_total_credits_history— compares with the latest entry, and on a change inserts this block's entry and prunes, bounded, every entry older than the one the limit reads this block (so the reference entry is never pruned, even across a chain halt).Drive::fetch_total_credits_in_platform_a_day_ago— the entry recorded at the latest block at least 24h before the given time (RangeToInclusive(..=now-24h), reverse, limit 1);Nonewhile no entry is that old (no younger fallback).calculate_current_withdrawal_limitv1 — hands that lagged total (orNone) todaily_withdrawal_limit, keepsavailable = daily_maximum - pooled_in_last_24h. The dispatcher now takes&BlockInfo.add_initial_withdrawal_state_structure_operations) and bytransition_to_version_14for upgrading networks.Per-block event (
rs-drive-abci) —record_total_credits_history_for_withdrawals(OptionalFeatureVersion,Some(0)in the newDRIVE_ABCI_METHOD_VERSIONS_V10,Nonebefore) runs inrun_block_proposalafterprocess_block_fees_and_validate_sum_trees— the last thing in a block that can move the total (epoch Core rewards land there) — and before the app hash is taken, so the entry carries the block's final total and is part of its state; it only writes when the total moved.DRIVE_ABCI_WITHDRAWAL_CONSTANTS_V3addstotal_credits_history_prune_limit: 64.Tables —
DRIVE_VERSION_V9(PV14's own) bumpscalculate_current_withdrawal_limitto 1 and gains the two new slots asOptionalFeatureVersion(Some(0)in V2,Nonein V1, whose dispatchers returnVersionNotActive— the history subtree does not exist before PV14); PV13 and earlier keep every table they shipped with, so replay is unchanged. PV14's doc header describes the rule.Why a day-old base
TOTAL_SYSTEM_CREDITSis the tracked total (it grows with asset locks and epoch core rewards, shrinks when withdrawal state transitions execute). Reading it live would let an inflated total raise the limit at once; the 24h lag gives a day to notice — including across activation, which is why the first day keeps the old flat limit instead of using a younger total. Same-day inflows do not raise the limit either; the percent is meant to be generous enough (today ~30k Dash held → ~4500 Dash/day, up from 2000).Core
Unchanged and not a dependency: pre-V24 Core caps unlocks at
LimitAmountV22(2000 Dash) per block (min(credit_pool, 2000), no sliding window — the window only arrives with V24) and checks the amount only at block level, so any daily total is minable across blocks; after V24 Core enforces 4000 Dash per 576-block window, whichmax_daily_withdrawal_amountnever exceeds. Today's mainnet total (~30k Dash) would give 4500 Dash/day uncapped, so the effective limit there is the 4000 cap until Core raises its capacity; the percent governs below ~26.7k Dash.How Has This Been Tested?

The existing TEST_PLATFORM_V3 withdrawal tests are unchanged.cargo check --workspace --all-targets, clippy-D warningson the touched crates.Breaking Changes
Consensus change gated on PV14: the amount of withdrawals pooled per day changes, and the withdrawals root tree gains a child (state root differs from PV14 builds before this PR). PV14 is unreleased.
