fix(commit-reveal): broadcast the whole reveal batch and pre-flight it before the commit - #340
Conversation
|
Note
|
| Layer / File(s) | Summary |
|---|---|
Preflight and batched reveal execution lib/commit-reveal.ts, lib/wallet/wallet-interface.ts |
The helper models commit and reveal transactions before broadcast, validates funding and mass limits, broadcasts ordered reveal batches, retries orphaned submissions, tracks spent outpoints, and reports all reveal IDs. Confirmation handling supports configurable timeouts. |
Batch behavior and failure validation tests/commit-reveal-batch-unit.spec.ts, tests/mint-loop-utxo-unit.spec.ts |
Tests cover fragmented UTXO batches, script usage, transaction ordering, preflight rejection, orphan retries, missed confirmations, reorgs, timeouts, and partial-broadcast results. |
Result propagation and API documentation api/browser.ts, components/kns-transfer/*, components/krc-721-transfer/*, components/screens/browser-api/kaspa/commit-reveal/*, components/send/krc20-send/*, docs/kastle-api.md |
Transfer and browser flows preserve commit IDs, consume all reveal IDs, and report landed transactions after failures. The API type and documentation expose optional revealTxIds. |
Token operation failure handling
| Layer / File(s) | Summary |
|---|---|
Error normalization and failure rendering lib/token-operation-error.ts, components/screens/full-pages/TokenOperationFailed.tsx, tests/token-operation-error-unit.spec.ts |
The shared helper converts unknown rejection values into displayable messages and classifies disconnection, timeout, and default failures. The failure screen uses the normalized result, and tests cover supported rejection values and classifications. |
Priority: ➖ Normal
Estimated code review effort: 4 (Complex) | ~60 minutes
Severity of issue fixed: Low
Merge Risk: 🟡 Moderate · up to d8626
Failure reporting can omit transactions that already landed, making recovery and retries unsafe, while commit rejection can produce a later unhandled timeout. These runtime issues should be resolved before merge.

🟡 Changes recommended
There are confirmed runtime-safety issues in the updated transaction ID aggregation in UI flows and a missing guard in commitScript() that can reintroduce partial/incorrect commit broadcasting if multiple commit transactions are produced.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR fixes the commit-reveal “B3” reveal leg so fragmented UTXO sets correctly broadcast (and confirm) the entire reveal batch, and adds a preflight step to ensure the reveal is buildable before broadcasting the commit (preventing known script-UTXO stranding cases). It also surfaces all reveal transaction IDs through the internal result type, UI success screens, and the kas:commit_reveal browser API response, with new unit coverage.
Changes:
- Add
preflightReveal()and batch-aware reveal broadcast/confirmation logic inCommitRevealHelper(money-path fix). - Expose
revealTxIds(all reveal tx IDs in order) in internal result types, UI flows, docs, andKastleBrowserAPI.commitReveal(). - Add unit tests covering batched reveal behavior, orphan retry semantics, and preflight refusal cases.

…t before the commit
On a fragmented UTXO set the Generator splits the reveal into a chained
batch (compactions first, the payment last). The reveal leg signed and
submitted only transactions[0] — a compaction paying the user's own
change — and the confirmation watcher, which accepted any transaction
paying the user, reported success. The inscription payment never
happened and the 0.3 KAS script UTXO was consumed for nothing. Only
KRC-20 deploy and dApp requests with a large revealPriorityFee reach
this shape; transfers and mint build a single transaction.
- Pre-flight: build the commit offline, derive the post-commit UTXO
set, and build the reveal against it plus a synthetic script UTXO
before anything is broadcast. Generator throws ("Insufficient
funds", "Mass calculation error", "Storage mass exceeds maximum")
now abort with nothing committed instead of stranding the P2SH.
- Sign every reveal transaction (redeem script on input 0 of the first
only), assert input 0 spends the script UTXO, and submit in order.
Orphan rejects resume at the same index; the batch is never rebuilt.
- Confirmation watches the final transaction: an added entry with its
id, or any of its inputs reported spent. `waitTxForAddress` matches
with `.some` so an event with several entries is not missed.
- Mass headroom: reject when transactions[0].mass plus the P2SH
signature script exceeds the 100,000 standard limit, pre-commit.
- Surface every reveal id: `revealTxId` is the last transaction, and
`revealTxIds` is added to the completed result, the wallet success
screens and the `kas:commit_reveal` dApp response.
Offline spec drives the real Generator and signer against a fake UTXO
set. It does not run against main as-is: it imports RevealBroadcastError
and broadcastBeforeFailure, which main's lib/commit-reveal.ts does not
export, so Playwright stops at "SyntaxError: The requested module
'@/lib/commit-reveal' does not provide an export named
'RevealBroadcastError'" and no test runs. Checked 2026-09-07 with those
two pure exports appended to main's file (worktree at 7e10fd2,
`playwright test tests/commit-reveal-batch-unit.spec.ts`): of the 11
cases now in the spec, 9 fail, 1 passes, and 1 never completes. The one
that passes ("only input 0 of the first reveal carries the redeem
script") cannot discriminate: main broadcasts only transactions[0],
whose input 0 is the script UTXO either way. The one that never
completes ("the commit that is broadcast is the one pre-flight modeled")
blocks the event loop on main — even Playwright's own test timeout does
not fire — so it is excluded from the counts rather than counted as a
failure. (Earlier versions of this message claimed "7 of 8 fail on
main"; that number was never produced, the spec could not be imported.)

…ed on failure Follow-ups from the adversarial review of fix/b3-reveal-batch. - The commit leg re-fetched the UTXO set and rebuilt the commit, then took transactions[0] unguarded — a different snapshot from the one pre-flight validated, and the defect class this branch removes from the reveal leg. preflightReveal now returns the commit it modeled and commitScript signs and submits exactly that. No divergence left to guard: the predicted reveal entries hang off that commit's id, and if the wallet moved in between, the node rejects the commit with nothing landed. - RevealBroadcastError.transactionIds had no consumer. broadcastBeforeFailure (commit id once "revealing" was seen, plus the reveals the error reports) feeds the KRC-20, KNS and KRC-721 fail screens through their existing transactionIds prop, and the kas:commit_reveal error string names the ids. No onFail signature changes, so nothing here depends on fix/b3-batch-family's `reason` widening. - docs: `revealTxIds` is "since 2.60.1", matching fix/b3-batch-family (release-please: fix → patch from 2.60.0). Spec: 10 cases (was 8). The wallet is read once before the commit and the broadcast commit is the pre-flighted one; a mid-batch reject surfaces as RevealBroadcastError with the landed ids. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…mation Follow-ups from the re-review of fix/b3-reveal-batch. - perform yielded commitTxId only on the "revealing" yield, after the commit confirmed. A commit the node accepted but the watcher missed (subscription miss, node lag, 120 s timeout) threw with no id, so broadcastBeforeFailure returned [] and the fail screens and the dApp error string said nothing had happened while 0.3 KAS sat at a P2SH the wallet keeps no record of — the stranding the pre-flight exists to prevent. A second "committing" yield now carries the id right after submit, before the confirmation await. The popup callers already keep the id sticky (result.commitTxId ?? commitTxId); HotWalletCommitReveal overwrote it per yield and is now sticky too. No status name added: CommitRevealResult's union and every setStep(result.status) caller are unchanged. - A reveal-confirmation timeout after a fully broadcast batch dropped every reveal id and threw. The watcher only rejects with "Timeout" or an RPC error of its own; neither undoes a broadcast the node already accepted, so the rejection is logged (console.warn) and `completed` still lists every id. A submit rejection still surfaces as RevealBroadcastError. - waitTxForAddress takes an optional timeout and commitScript passes the helper's confirmationTimeoutMs so the commit watcher is testable. Production default unchanged (120 s). - preflightReveal docstring: the reason the modeled commit must be the one broadcast is entry-set fidelity — a rebuilt commit could spend different inputs or split into a batch — not the id, which only seeds a synthetic outpoint of fixed size. Spec: 11 cases (was 10). "completion is not reported when only the compaction is confirmed" is replaced by its inverse (a silent final transaction still completes with every id), and a silent commit still reports its id with 0.3 KAS at the P2SH. Not covered: DeployingToken and MintingToken also consume perform but never tracked commitTxId or used broadcastBeforeFailure; unchanged here. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Validate the commit-reveal response at runtime.
This new public response shape is only a TypeScript annotation. receiveMessageWithTimeout returns parsedMessage.response as T, so revealTxIds is not checked before it crosses the browser API boundary. Add a Zod schema for the commit-reveal response and parse it before returning the result. Otherwise malformed data can reach consumers that spread revealTxIds and fail at runtime.
As per coding guidelines, **/*.ts: Use Zod for validation of all API payloads and message schemas, following patterns from api/message.ts.

Preserve completed reveal IDs when post-broadcast work fails.
CommitRevealHelper.perform() yields completed commit and reveal IDs, but broadcastBeforeFailure() returns only the commit ID and IDs from RevealBroadcastError. If response delivery, recent-transfer persistence, or onSuccess() throws after completion, each catch replaces the complete landed state with commit-only IDs. The dApp or failure screen then omits reveal transactions that already landed.
Retain the completed IDs in each caller and merge them with broadcastBeforeFailure(...) before returning the failure response or calling onFail(). Use the same merge rule, with caller-specific retention in all four components.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Attach a rejection handler to confirm when the commit submit fails.
waitTxForAddress starts here and is returned as confirm. If this.rpcClient.submitTransaction rejects on the next statement, perform throws and no caller ever awaits confirm. The watcher then rejects with Error("Timeout") after the timeout with no handler attached, which produces an unhandled promise rejection.
The comment on Line 299 names this exact case: a moved UTXO set makes the node reject the pre-flighted commit. revealScript already guards the same hazard on Line 462 with confirm.catch(() => undefined).
Consumers call captureException, so the stray "Timeout" rejection can also be reported as a separate error after the real failure was already handled.

TokenOperationFailed rendered {error} straight from location state. The
Generator and the RPC reject with strings, which React renders; every
Error object hit React error #31 ("Objects are not valid as a React
child") — the "Unexpected Application Error" Leo saw on a failed mint.
main already threw Errors for "Timeout" and a missing script UTXO; this
branch widened it by wrapping the Generator's rejections in Errors, so an
insufficient-funds mint went from a readable message to a crash.
Reduce whatever perform() rejected with to a string in one place
(lib/token-operation-error.ts) and render that. The commit-leg timeout
("Timeout") now maps to the mempool-timeout copy it always had; the
reveal leg no longer throws on timeout on this branch.
tests/token-operation-error-unit.spec.ts renders the message in the
screen's exact position with react-dom/server for every rejection shape,
and keeps a control proving an Error there still throws.

Manual-QA follow-up: defect 1 — 0433a99React #31 on a failed mint. Pre-existing on main for Fix: Gates: tsc 0 · eslint clean · prettier clean · Playwright 126 passed · build ok · lockfile |
…spent Reproduced on testnet-10 (2026-09-07, MMMM, 11 of 20 mints): the commit of iteration 11 spent d17b29a9:1, the change of commit 10, while reveal 10 (700fbf70), which spends that same outpoint, was still in the mempool. The node rejected it with "already spent by transaction … in the mempool". The reveal watcher resolved before the reveal was accepted. Its "any of the final transaction's inputs removed" clause — added with the batch reveal so a reveal that folds entirely into fee is still observed — matches a virtual flip that un-applies the COMMIT: the reveal's inputs are exactly the commit's outputs. Such flips are constant on a busy DAG (measured on testnet-10 with the extension's WASM client: 5,163 outpoints removed then re-added, 10,019 added twice, in 150 s across 9 busy addresses). The loop then re-read the node's UTXO index, which had the re-applied commit change and no knowledge of the mempool reveal, and built the next commit over it. main is not exposed: its reveal watcher matches only the reveal's own id, and a rejected watcher throws instead of proceeding. - Every helper on a connection records the outpoints of what it broadcast (module WeakMap keyed by RpcClient, so a retry after a failure and the next iteration both see it). Both wallet reads — pre-flight and reveal — re-read until the node no longer lists a recorded outpoint, and fail closed after the confirmation timeout instead of double-spending. The pre-flighted commit is still the one broadcast. - The reveal watcher's removed-inputs clause only counts in an event that adds nothing of ours; a flip hands the commit's inputs back in the same event. Offline spec: a node with a mempool (rusty-kaspa's exact rejection), mining, and revert/reapply. Before this change 3 of 4 cases fail with the reproduced message; after it all pass, and inputs are disjoint across iterations. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Update 2026-09-07 — Diagnosis, from the chain: Fix (keeps the pre-flighted commit as the broadcast one):
|
- Validate the commitReveal browser API response with Zod before it reaches the dApp, matching the payload schemas. - Keep every landed reveal id when a failure happens after perform() completed (response delivery, persistence, onSuccess), instead of collapsing the fail screen and the dApp response to the commit alone. - Attach a rejection handler to the commit confirmation watcher so a rejected submit does not later surface its timeout as an unhandled promise rejection.

commitTxIdwas carried only by therevealingyield, afterawait commitTxIdConfirm. A watcher miss (subscription miss, node lag, 120 s timeout) threw withcommitTxId === undefined,broadcastBeforeFailurereturned[], and every fail screen and the dApp error said nothing happened while 0.3 KAS sat at an unrecorded P2SH. Fix (lib/commit-reveal.ts): a secondcommittingyield carries the id right aftersubmitTransaction, before the confirmation await.KNSTransferBroadcast,KRC721TransferBroadcast,HotWalletBroadcastTokenOperationalready keep the id sticky;HotWalletCommitReveal.tsxnow does too. Status name unchanged:CommitRevealResultand everysetStep(result.status)caller (includingDeployingToken/MintingToken) are untouched. Spec: silent commit → throwsTimeout, statuses["committing","committing"],broadcastBeforeFailure=[commit.id], 0.3 KAS at the P2SH.await revealConfirmnow.catches andconsole.warns;completedstill lists every id. Safe to swallow: the watcher only rejects withTimeoutor its own RPC error, both after every reveal transaction was accepted at submit; a submit rejection still surfaces asRevealBroadcastError. Spec inverted accordingly ("a reveal confirmation timeout still reports every broadcast transaction").waitTxForAddresstakes an optionaltimeoutMs;commitScriptpasses the helper'sconfirmationTimeoutMs. Production default unchanged (120 s).preflightRevealdocstring argues from entry-set fidelity (inputs / batch split), not from the id, which only seeds a fixed-size synthetic outpoint.SyntaxError: The requested module '@/lib/commit-reveal' does not provide an export named 'RevealBroadcastError'— no test runs. With the two pure exports (RevealBroadcastError,broadcastBeforeFailure) appended to main's file in a worktree at 7e10fd2, the 11-case spec gives 9 failed, 1 passed, 1 never completes. The passing case ("only input 0 of the first reveal carries the redeem script") cannot discriminate — main broadcasts onlytx[0], whose input 0 is the script UTXO either way. The non-completing case ("the commit that is broadcast is the one pre-flight modeled") blocks the event loop on main: with--timeout=20000 --retries=0 --workers=1Playwright printsRunning 1 test using 1 workerand nothing else for 75 s.
