151-174: Test mock return value doesn't match expected interface.Similar to the previous test,
fetchLastSavedMessagereturns"message-3"instead of the expected object shape{ id, stateRoot }. This will cause the destructuring on line 90 ofsnapshot.tsto fail or produce unexpected results.🔎 Proposed fix
- fetchLastSavedMessage = jest.fn().mockResolvedValue("message-3"); + fetchLastSavedMessage = jest.fn().mockResolvedValue({ id: "inbox-3", stateRoot: "0xdifferent" });relayer-cli/src/utils/relay.ts (1)
178-186: PotentialNaNreturn when no messages are relayed.If
lastNonceremainsnull(no messages relayed for any sender), line 185 returnsnull + 1which evaluates to1in JavaScript (notNaNas I initially thought, sincenullcoerces to0). However, returning1when nothing was relayed may be misleading.The return value should indicate that no messages were relayed to avoid confusion for callers.
🔎 Proposed fix
if (lastNonce != null) { const gasLimit = await batcher.batchSend.estimateGas(targets, values, datas); const tx = await batcher.batchSend(targets, values, datas, { gasLimit }); const receipt = await tx.wait(); emitter.emit(BotEvents.RELAY_ALL_FROM, nonce, msgSenders, receipt.hash); + return lastNonce + 1; } - return lastNonce + 1; // return current nonce + return null; // No messages were relayed };relayer-cli/src/utils/relayerHelpers.ts (1)
81-81: Inconsistent path construction may cause issues.Line 34 uses
path.join(stateDir, ...)which handles missing trailing slashes, but line 81 uses string concatenation withprocess.env.STATE_DIR + network + .... IfSTATE_DIRlacks a trailing slash, this will produce an incorrect path like/path/to/statenetwork_123.json.Suggested fix
- const chain_state_file = process.env.STATE_DIR + network + "_" + chainId + ".json"; + const chain_state_file = path.join(stateDir, `${network}_${chainId}.json`);validator-cli/src/utils/graphQueries.ts (1)
23-35: Functions returnundefinedfor unsupported chain IDs.Both
getOutboxSubgraphUrlandgetInboxSubgraphUrllack a default return/throw for unsupported chain IDs. This causes implicitundefinedreturns while the type signature promisesstring. Callers likegetClaimsForEpochspass this directly torequest(), which will fail with an unclear error.Suggested fix
const getOutboxSubgraphUrl = (chainId: number): string => { if (chainId === 11155111) { return process.env.VEAOUTBOX_SUBGRAPH_SEPOLIA || ""; } else if (chainId === 10200) { return process.env.VEAOUTBOX_SUBGRAPH_CHIADO || ""; } + throw new Error(`Unsupported outbox chain ID: ${chainId}`); }; const getInboxSubgraphUrl = (chainId: number): string => { // using destination chainId's for inbox if (chainId === 11155111 || chainId === 10200) { return process.env.VEAINBOX_SUBGRAPH_ARBSEPOLIA || ""; } + throw new Error(`Unsupported inbox chain ID: ${chainId}`); };

relayer-cli/src/utils/proof.ts (1)
23-53: Consider adding explicit return type annotation.The
getMessageDataToRelayfunction lacks an explicit return type annotation. Adding one would improve type safety and make it clearer that the function returns a 3-element tuple.🔎 Suggested type annotation

28-28: Consider using a caret range forpino-pretty.The version
13.1.2is pinned exactly, while other dependencies use caret ranges (e.g.,^6.13.5,^10.1.0). Based on learnings, floating versions are preferred in this project. Consider changing to^13.1.2for consistency.🔎 Proposed fix
- "pino-pretty": "13.1.2", + "pino-pretty": "^13.1.2",relayer-subgraph-inbox/src/vea-inbox.ts (2)
28-28: Downgrade debug log fromlog.errortolog.infoorlog.debug.This log statement appears to be for debugging purposes rather than an actual error condition. Using
log.errorfor routine message processing can pollute error logs and make it harder to identify real issues.🔎 Proposed fix
- log.error("processing {}", [_nonce.toString()]); + log.info("processing {}", [_nonce.toString()]);
83-83: Same issue: downgrade debug log fromlog.errortolog.info.🔎 Proposed fix
- log.error("processing {}", [entity.nonce.toString()]); + log.info("processing {}", [entity.nonce.toString()]);relayer-cli/src/consts/bridgeRoutes.ts (1)
22-24: Consider improving inline comments for clarity.The comments for
yaruAddressandhashiAddressboth say "Hashi (Yaru) contract address", buthashiAddressis the Hashi contract, not Yaru. This appears to be a copy-paste oversight.🔎 Proposed fix
- yahoAddress?: string; // Hashi (Yaru) contract address - yaruAddress?: string; // Hashi (Yaru) contract address - hashiAddress?: string; // Hashi (Yaru) contract address + yahoAddress?: string; // Yaho contract address (on source chain) + yaruAddress?: string; // Yaru contract address (on destination chain) + hashiAddress?: string; // Hashi contract address (on destination chain)validator-cli/Dockerfile (1)
41-42: TypeChain skip logic may lead to stale artifacts.The conditional
[ -d contracts/typechain-types ]skips the build if the directory exists, but this could result in stale TypeChain types if contracts have changed. Consider removing the condition to always rebuild, or use a more robust cache invalidation strategy.🔎 Alternative: Always rebuild to ensure fresh artifacts
-RUN [ -d contracts/typechain-types ] && echo "TypeChain present, skipping build" || yarn workspace @kleros/vea-contracts build +RUN yarn workspace @kleros/vea-contracts buildIf build time is a concern, Docker layer caching on the
COPYstep (line 36) will naturally invalidate when contracts change.validator-cli/src/helpers/snapshot.test.ts (1)
13-14: Unused mockfetchClaimForEpochin tests.The
fetchClaimForEpochmock is defined and passed to test parameters, but based on theisSnapshotNeededfunction signature insnapshot.ts(lines 60-69 in relevant code snippets), there is nofetchClaimForEpochparameter—onlyfetchLastClaimedEpoch. This mock appears to be dead code.Either remove the unused mock or verify if this is intended for a future implementation.
🔎 Proposed fix
- let fetchClaimForEpoch: jest.Mock; ... - fetchClaimForEpoch = jest.fn().mockResolvedValue({ - stateRoot: "0xabcde", - });And remove
fetchClaimForEpochfrom all test params objects.Also applies to: 33-35, 52-53

4-19: Missing environment variable validation and potential GraphQL injection.
No validation for
RELAYER_SUBGRAPH: If undefined,request(undefined, query)will fail with an unclear error.Potential GraphQL injection (Line 7): The
inboxAddressis directly interpolated into the query string. While this comes from internal sources, consider using parameterized queries if supported.Console.log for errors (Line 16): Should use structured logging consistent with the project's logging utilities.
🔎 Proposed fix for validation
async function getVeaMsgTrnx(nonce: number, inboxAddress: string) { try { const subgraph = process.env.RELAYER_SUBGRAPH; + if (!subgraph) { + throw new Error("RELAYER_SUBGRAPH environment variable is not set"); + } const query = `{messageSents(first: 1, where: {nonce: ${nonce}, inbox: "${inboxAddress}"}) {Based on learnings, environment variable validation will be handled during dockerization, so this may be deferred.
63-85: Type inconsistency in return value.Line 84 maps
noncewith type annotation{ nonce: string | number }, but theMessageSentinterface on line 48-50 definesnonceasnumber. The GraphQL response likely returns strings for numeric values.Also, consider adding error handling similar to
getVeaMsgTrnxfor consistency.🔎 Proposed fix for type consistency
interface MessageSent { - nonce: number; + nonce: string; } ... - return result[`messageSents`].map((a: { nonce: string | number }) => Number(a.nonce)); + return result.messageSents.map((msg) => Number(msg.nonce));relayer-cli/.env.dist (1)
27-27: Add trailing newline.The file should end with a blank line for proper formatting.
🔎 Proposed fix
# Hashi Executor enabler HASHI_EXECUTOR_ENABLED=true +relayer-cli/src/utils/heartbeat.ts (3)
6-9: Unusedstatusparameter.The
statusparameter is declared but never used in the function. If it's intended for future use, consider documenting this. Otherwise, remove it or incorporate it into the heartbeat request (e.g., as a query parameter or in the User-Agent).
22-43: Consider removing unused response data accumulation.The response data is accumulated but never used. Since this is a fire-and-forget heartbeat, you can remove the data accumulation for clarity.
🔎 Proposed refactor
return new Promise((resolve, reject) => { const req = https.request(options, (res) => { - let data = ""; - res.on("data", (chunk) => { - data += chunk; - }); res.on("end", () => { resolve(); }); });
44-46: Silent error handling is acceptable for heartbeat telemetry.The silent failure approach is appropriate for non-critical heartbeat signals. However, for debugging purposes, consider optionally logging errors when a debug flag is enabled.
validator-cli/src/helpers/validator.ts (1)
53-60: Verify finality check flow and unused destructured element.
The destructuring on line 54 skips element at index 1 (appears to be ethBlock based on the function name). Confirm this is intentional and the value is not needed downstream.
The check
res === undefined || finalityIssueFlagArb || finalityIssueFlagEthon line 55 could throw ifresis actuallyundefinedsince the destructuring on line 54 would fail first. Consider reordering:🔎 Suggested safer pattern
- const res = await fetchBlocksAndCheckFinality(queryRpc, veaInboxProvider, epoch, epochPeriod, emitter); - const [arbitrumBlock, , finalityIssueFlagArb, finalityIssueFlagEth] = res; - if (res === undefined || finalityIssueFlagArb || finalityIssueFlagEth) { + const res = await fetchBlocksAndCheckFinality(queryRpc, veaInboxProvider, epoch, epochPeriod, emitter); + if (!res) { + emitter.emit(BotEvents.FINALITY_ISSUE, epoch); + return null; + } + const [arbitrumBlock, , finalityIssueFlagArb, finalityIssueFlagEth] = res; + if (finalityIssueFlagArb || finalityIssueFlagEth) { emitter.emit(BotEvents.FINALITY_ISSUE, epoch); return null; }validator-cli/src/utils/heartbeat.ts (1)
1-47: Code duplication with relayer-cli heartbeat utility.This file is nearly identical to
relayer-cli/src/utils/heartbeat.ts. Consider extracting to a shared package to reduce maintenance burden and ensure consistent behavior.relayer-cli/src/utils/hashi.test.ts (3)
6-14: MockEmitter duplicated from validator-cli.This
MockEmitterclass is identical to the one invalidator-cli/src/utils/emitter.ts. Consider importing from a shared location or extracting to a common test utilities module.
118-131: Inconsistent mock return values for hasThresholdMet.Line 110 uses
HashiExecutionStatus.EXECUTABLEwhile line 126 usesfalse. For consistency, line 126 should useHashiExecutionStatus.NOT_EXECUTABLEor similar enum value if one exists.
17-17: Useconstfor mockEmitter.
mockEmitteris never reassigned.- let mockEmitter = new MockEmitter(); + const mockEmitter = new MockEmitter();validator-cli/src/utils/logger.ts (1)
9-10: Consider making log level configurable.The log level is hardcoded to "debug". Consider making it configurable via environment variable for production deployments where you may want "info" or higher.
const loggerOptions = { - level: "debug", + level: process.env.LOG_LEVEL || "debug", base: { service: "Vea" },relayer-cli/src/utils/hashiHelpers/hashiMsgUtils.ts (3)
11-23: Return type inconsistency:BigIntvsbigint.The function signature declares
BigInt(the constructor/wrapper object type) buthexToBigInt32Bytesreturnsbigint(the primitive type). While TypeScript allows this assignment, using the primitivebigintis more idiomatic and consistent.Suggested fix
export function getHashiMsgId( sourceChainId: bigint | number | string, dispatcherAddress: string, message: HashiMessage -): BigInt { +): bigint {
34-41: Unreachable code branch formessage.datahandling.Per the
HashiMessageinterface,datais typed asstring. Theelsebranch at line 41 (getBytes(message.data)) is unreachable since thetypeof message.data === "string"condition will always be true. Consider removing the dead branch or updating the type if byte arrays are expected.Simplified version
- const data = - typeof message.data === "string" - ? isHexString(message.data) - ? message.data - : (() => { - throw new Error("message.data must be 0x-hex"); - })() - : getBytes(message.data); + if (!isHexString(message.data)) { + throw new Error("message.data must be 0x-hex"); + } + const data = message.data;
56-63: Consider using ethers' native BigInt conversion.The manual byte iteration can be replaced with a direct conversion. The
BigInt()constructor in JavaScript natively handles hex strings prefixed with0x.Simplified version
function hexToBigInt32Bytes(hex32: string): bigint { - const bytes = toBeArray(hex32); - // Convert bytes to BigInt (big-endian) - let n = BigInt(0); - for (const b of Array.from(bytes)) { - n = (n << BigInt(8)) + BigInt(b); - } - return n; + return BigInt(hex32); }validator-cli/src/utils/claim.ts (1)
79-126: Duplicated graph fetch and claim population logic.Lines 81-96 (in catch block) and lines 103-118 (in post-validation) contain nearly identical code for fetching from graph and populating claim fields. Consider extracting to a helper function to reduce duplication and maintenance burden.
Example helper extraction
const populateClaimFromGraph = async ( claim: ClaimStruct, claimFromGraph: ClaimData, veaOutboxProvider: JsonRpcProvider ): Promise<void> => { claim.stateRoot = claimFromGraph.stateroot; claim.claimer = claimFromGraph.bridger; claim.timestampClaimed = claimFromGraph.timestamp; if (claimFromGraph.verification?.startTimestamp) { claim.timestampVerification = claimFromGraph.verification.startTimestamp; const txReceipt = await veaOutboxProvider.getTransactionReceipt(claimFromGraph.verification.startTxHash); claim.blocknumberVerification = txReceipt.blockNumber; } if (claimFromGraph.challenge) { claim.challenger = claimFromGraph.challenge.challenger; } };relayer-cli/src/utils/hashi.ts (1)
54-61: No error handling for individual message status checks.If
isMessageExecutablethrows for any nonce, the entire executor stops without processing remaining messages or saving progress. Consider wrapping in try/catch to log errors and continue with remaining nonces.Suggested error handling
while (nonce < inboxCount) { // ToDo: Add cooldown periods for nonces that cannot be executed. - const messageState = await isMessageExecutable({ chainId, nonce, veaInboxAddress, rpcInbox }); - if (messageState != null && !messageState.executed) { - executableNonces.push(messageState); + try { + const messageState = await isMessageExecutable({ chainId, nonce, veaInboxAddress, rpcInbox }); + if (messageState != null && !messageState.executed) { + executableNonces.push(messageState); + } + } catch (e) { + // Log error but continue processing remaining nonces + console.error(`Failed to check message status for nonce ${nonce}:`, e); } nonce++; }

100-109: Remove duplicate Hashi event listeners.These event listeners duplicate the handlers already defined at lines 89-98. Both sets will fire for each event, causing:
- Duplicate log entries (structured + console)
- Inconsistent logging output
- Performance overhead
These lines appear to be leftover code from the console.log-to-pino migration and should be removed.
🔎 Proposed fix

validator-cli/src/helpers/claimer.ts (2)
139-144: Consider explicit array length check for clarity.Line 140 accesses
lastClaimLogs[lastClaimLogs.length - 1].datawithout checking if the array is empty. If no claims exist yet, this throws and execution moves to the catch block. While functionally correct (the fallback handles it), an explicit length check would make the intent clearer:try { const lastClaimLogs = await veaOutbox.queryFilter(veaOutbox.filters.Claimed()); if (lastClaimLogs.length > 0) { lastClaimedStateroot = lastClaimLogs[lastClaimLogs.length - 1].data; } else { // Explicitly handle no claims case const claimData = await fetchLatestClaimedEpoch(veaOutbox.target, chainId); lastClaimedStateroot = claimData ? claimData.stateroot : ethers.ZeroHash; } } catch { const claimData = await fetchLatestClaimedEpoch(veaOutbox.target, chainId); lastClaimedStateroot = claimData ? claimData.stateroot : ethers.ZeroHash; }This distinguishes between "no claims yet" and "query failed," improving debuggability.
145-147: Optional: Potentially unreachable null check.Since both the try block (line 140) and catch block (line 143) assign a value to
lastClaimedStateroot, the null check at lines 145-147 appears unreachable unless the catch block itself throws (in which case the function would throw, not return null).If you intend this as defensive programming, consider adding a comment. Otherwise, you could remove these lines as the subsequent logic at line 148 will handle all valid cases.

blocknumberVerification: 0with a comment noting additional data is needed. However, whenclaim.verification?.startTxHashis available, you could fetch the transaction receipt to get the actual block number (similar to lines 93-94 ingetClaim).🔎 Potential enhancement
This would require making additional provider calls, so it might be a trade-off between accuracy and performance. Alternatively, document that callers should not rely on
blocknumberVerificationorhonestfields from this function.

Learning: In the Vea relayer-cli project, HashiMessage interface and related types use simple number and string types. Type conversion and normalization (e.g., number to bigint, string to bytes) is handled in encoding utilities like encodeMessageForAbi before on-chain calls, rather than widening the interface types themselves.

Learning: In the validator-cli, `any` type is intentionally used for `veaInbox` and `veaOutbox` parameters to maintain chain agnosticism. This is because different chains have their own specific contract types (e.g., VeaInboxArbToEth, VeaOutboxArbToEth, VeaOutboxArbToGnosis) and using union types would make the code more complex and less maintainable.

21-21: LGTM: Interface extensions support router-based finality checks.The optional
veaRouterProviderandfetchBlocksAndCheckFinalityparameters properly support the new arbToEth finality validation flow without breaking existing callers.Also applies to: 27-27
77-90: LGTM: Proper parameter threading with sensible fallback.The
queryRpc = veaRouterProvider ?? veaOutboxProviderfallback ensures backward compatibility when the router provider isn't supplied, while supporting the new router-based claim flow.
148-165: LGTM: Properly handles new claims with finality validation.The refactored logic correctly:
- Compares
savedSnapshotagainst bothoutboxStateRootandlastClaimedStaterootto detect new messages- Validates finality before proceeding with claims
- Handles the first-ever claim scenario (when
lastClaimedStateroot == ethers.ZeroHash) by allowing progression through the comparison logicThe finality check integration prevents claiming when finality issues are detected, improving system resilience.
validator-cli/src/helpers/claimer.test.ts (1)
196-197: LGTM: Mock properly supports new finality check flow.The
fetchBlocksAndCheckFinalitymock returns[0, 0, false, false], where the last two boolean values representfinalityIssueFlagArbandfinalityIssueFlagEth. Thefalsevalues correctly simulate the no-finality-issues case, allowing the test to verify successful claim execution.validator-cli/src/helpers/snapshot.test.ts (5)
4-4: LGTM: Test setup properly extended for new snapshot logic.The additions correctly support the enhanced
isSnapshotNeededinterface:
ethersimport providesZeroHashconstantnetworkandepochPeriodenable snapshot timing logicfetchLastClaimedEpochandfetchClaimForEpochmocks support claim-based snapshot decisions- Extended
veaOutboxmock withqueryFilterandClaimedfilter matches production contract interfaceAlso applies to: 7-7, 11-11, 14-15, 28-36
46-55: LGTM: Test parameters consistently updated across all cases.All test cases now properly pass
network,epochPeriod,fetchLastClaimedEpoch, andfetchClaimForEpochto match the expandedisSnapshotNeededsignature. The consistent threading maintains comprehensive test coverage.Also applies to: 68-78, 91-101, 114-124, 136-146, 160-170
134-134: Fixed: Mock return type now matches production interface.The
fetchLastSavedMessagemock now correctly returns an object with{ id, stateRoot }properties instead of a plain string. This addresses the previous review concern and properly exercises the fallback logic insnapshot.ts(lines 86-93).
159-159: LGTM: Proper use of ethers constant.Using
ethers.ZeroHashinstead of a hardcoded zero address improves readability and consistency with ethers v6 conventions.
56-59: LGTM: Proper async test pattern.All test expectations correctly use
await expect(...).resolves.toEqual(...)to properly handle the asyncisSnapshotNeededfunction, ensuring promises are resolved before assertions.Also applies to: 79-82, 102-105, 125-128, 147-150, 171-174
validator-cli/src/utils/claim.ts (3)
235-254: Good fix: verifyClaimHash no longer mutates the claim object.The implementation now creates copies with different
honeststates instead of mutating the input. This addresses the concern from a previous review and makes the function more predictable.
79-126: Robust fallback logic with proper error handling.The implementation handles multiple failure scenarios:
- Primary on-chain fetch with graph fallback
- Hash validation with secondary graph fallback if needed
- Emitter events for observability (NO_CLAIM_FETCHED, CLAIM_MISMATCH)
- isFallbackUsed flag prevents redundant graph queries
68-69: Use consistent block range parameters across all queryFilter calls.The
ChallengedandVerificationStartedfilters don't specifyfromBlockortoBlock, while theClaimedfilter does. Since these parameters are passed togetClaim, they should be applied consistently to all three queries for optimization and maintainability.validator-cli/src/utils/graphQueries.ts (2)
259-282: Correct nullable return type and proper error handling.The function now correctly returns
nullwhen no messages exist and throwsNoMessageSavedErroron actual failures. This addresses the type mismatch noted in a previous review.
55-61: Enhanced query includes verification and challenge data.The GraphQL query now fetches nested
verificationandchallengefields, properly aligning with the updatedClaimDatainterface and supporting the improved claim validation logic inclaim.ts.

7-11: LGTM!Docker command substitution is clear and aligns with the project's shift to Docker-based deployment. The build and run commands are straightforward and correct.
13-16: LGTM!The workflow descriptions accurately capture the two core functions introduced in this PR: snapshot saving/submission (Bridger) and claim validation (Challenger). These align well with the new snapshot and claimer logic mentioned in the PR objectives.
26-30: LGTM!The
--pathflag documentation is clear and provides good granular control. The three modes (challenger, bridger, both) are well-defined, and the default behavior is appropriately indicated.

In @relayer-cli/src/relayer.ts:
- Around line 100-103: The time calculation incorrectly divides currentTS twice;
update the logic in the function using currentTS, getEpochPeriod, and timeLeft
so you use currentTS (seconds) directly: compute remainder as (currentTS %
epochPeriod), set timeLeft = (epochPeriod - (currentTS % epochPeriod)) * 1000 +
100_000 (to keep the 100s buffer in ms), and keep returning Date.now() +
timeLeft; remove the extra Math.floor(currentTS / 1000) division to fix the
double-division bug.
In @relayer-cli/src/utils/hashi.ts:
- Around line 51-57: The code destructures bridgeConfig from fetchBridgeConfig
(getHashiBridgeConfig) without checking for undefined which can throw; update
the logic in the function containing the lines with bridgeConfig, yaruAddress,
yahoAddress, hashiAddress, and sourceRPC to first check if bridgeConfig is falsy
and if so emit BotEvents.HASHI_NOT_CONFIGURED with targetChainId and return
legacyBlockNumber (or blockNumber) to preserve retry state; only then
destructure the properties and keep the existing falsy-address check to emit the
event and return legacyBlockNumber instead of 0.
In @relayer-cli/src/utils/relayerHelpers.ts:
- Around line 76-86: The state file path is built via string concatenation which
can break if STATE_DIR lacks a trailing slash; instead use the existing stateDir
variable and path.join to construct chain_state_file (combine stateDir,
`${network}_${chainId}.json`) before calling fileSystem.writeFileSync; update
references in this block to use stateDir and the joined path so path handling is
consistent with the earlier use of path.join.

137-147: Consider adding listener guard for 'exit' event as well.Signal handlers (SIGINT, SIGTERM, SIGQUIT) check

244-256: Inconsistent case normalization in address comparison.Line 246 uses

44-51: Heartbeat calls may block the watch loop if the heartbeat service is slow or unavailable.The
sendHeartbeatcalls areawaited inside the main loop. If the heartbeat endpoint is unresponsive or slow, this could delay epoch processing. Consider:
- Adding a timeout to heartbeat requests
- Using fire-and-forget (non-blocking) for "running" heartbeats
- Wrapping in try-catch to prevent heartbeat failures from crashing the watcher
Based on learnings, errors are intentionally left uncaught to allow crash & restart, but heartbeat failures shouldn't be treated as critical errors that warrant a crash.

Learning: In `relayer-cli/src/devnetRelayExample.ts`, error handling is managed by the upper layer via `ShutdownManager`'s error signal handler, so adding a `try...catch` block in the main loop is unnecessary.

Learning: In the `relayer-cli/src/devnetRelayExample.ts` file and similar contexts within the project, explicit handling of unhandled promise rejections when starting the application is not necessary. The team prefers relying on Node.js's default behavior to naturally raise and log errors in such cases, avoiding additional fallback handlers.

14-16: Add example RPC endpoint URLs to .env.dist.The three new RPC variables (
RPC_ARBITRUM_SEPOLIA,RPC_STORY,RPC_ARBITRUM_ONE) are used inbridgeRoutes.tswith non-null assertions, and environment validation is deferred to the Docker layer. However,.env.distshould include example endpoint URLs (e.g., public RPC providers or testnet endpoints) to guide developers setting up locally, rather than leaving them empty.
18-22: VEAOUTBOX_CHAINS and HASHI_CHAINS are independent configuration filters; no inconsistency exists.These environment variables control which routes an operator chooses to relay, not which chains are supported.
VEAOUTBOX_CHAINSspecifies target chains for VeaOutbox relay, whileHASHI_CHAINSspecifies source-target chain pairs for Hashi relay. An operator can legitimately exclude chain 10200 fromVEAOUTBOX_CHAINSwhile keeping the421614-10200Hashi route active, as these are separate relay systems with separate operational requirements.Likely an incorrect or invalid review comment.
relayer-cli/src/utils/relayerHelpers.test.ts (3)
23-37: LGTM!Tests correctly updated to reflect the
hashiNonce→hashiBlockNumberrename. Mock data, destructuring, and assertions are all consistent with the new naming convention.
39-54: LGTM!Existing state file test properly validates that
hashiBlockNumberis returned from persisted state.
57-68: LGTM!The
updateStateFiletest correctly validates the new JSON structure withhashiBlockNumberfield.relayer-cli/state/devnet_11155111.json (1)
1-5: LGTM!State file correctly updated with the
hashiBlockNumberfield rename, consistent with the codebase-wide change fromhashiNonce.relayer-cli/state/testnet_11155111.json (1)

hashiBlockNumberfield.relayer-cli/state/testnet_42161.json (1)
1-5: LGTM!New testnet state file for Arbitrum One (chain 42161) follows the expected structure with
hashiBlockNumberfield. Thenonce: 0indicates a fresh state initialization.relayer-cli/src/utils/hashiHelpers/bridgeRoutes.ts (2)
42-45: LGTM!The lookup function is clean and straightforward. Returns
undefinedfor unknown chain pairs, which is appropriate for the callers to handle.
16-17: Environment variables are documented in.env.distand validation is handled during dockerization.The non-null assertions on
RPC_ARBITRUM_SEPOLIA,RPC_SEPOLIA,RPC_CHIADO,RPC_STORY, andRPC_ARBITRUM_ONEare intentional. These variables are clearly documented in the.env.distfile, and environment variable validation for the multi-network relayer is handled during the dockerization process rather than through inline checks.relayer-cli/src/utils/logger.ts (2)
5-27: LGTM - well-structured logger configuration.The pino logger setup with conditional Logtail vs pino-pretty transport is clean. The
getLoggerhelper enables context-scoped child loggers.
44-98: LGTM - structured logging with appropriate log levels.Event handlers are well-organized with proper log levels:
infofor state transitions,debugfor operational details, anderrorfor exceptions. The structured context objects (e.g.,{ chainId, network },{ nonce, tx }) enable effective log filtering and analysis.relayer-cli/src/utils/relayerHelpers.ts (2)
198-211: LGTM - Hashi chain configuration parsing.The parsing of
HASHI_CHAINSenvironment variable with thesourceChainId-targetChainIdformat is straightforward. Based on learnings, environment variable validation will be addressed during dockerization.
160-165: LGTM - clean type extension.The
RelayerNetworkConfigtype extension with optionalsourceChainIdis well-documented and maintains backward compatibility.relayer-cli/src/utils/hashiHelpers/hashiTypes.ts (1)
1-31: LGTM - well-designed type system for Hashi workflow.The new types (
HashiMessageState,HashiMessageExecutionVars,DispatchedTxnData) provide a clean abstraction for the log-driven Hashi message workflow. Theexecutableboolean andstatusenum inHashiMessageStateenable clear state tracking. Based on learnings, type conversion tobigint/bytes is handled in encoding utilities before on-chain calls.relayer-cli/src/relayer.ts (2)
34-54: LGTM - heartbeat integration and per-network scheduling.The heartbeat telemetry integration and per-network execution timing via
executeTimesarray is well-structured. The scheduling logic correctly skips networks until their scheduled time.
78-89: LGTM - clean Hashi executor integration.The Hashi path correctly checks for
sourceChainId, runs the executor, updates state withhashiBlockNumber, and returns the next cycle time. The early return cleanly separates Hashi from non-Hashi flows.relayer-cli/src/utils/hashi.test.ts (2)
98-125: LGTM - comprehensive toExecuteMessage test coverage.The three test cases cover all execution states: executable (EXECUTABLE), non-executable (THRESHOLD_NOT_MET returning null), and already executed (EXECUTED with executable=false). Assertions correctly verify the
HashiMessageStateshape.
135-211: LGTM - thorough runHashiExecutor test coverage.Tests cover key scenarios: empty message list, non-executable messages (already executed), and executable messages. The mock setup correctly simulates the Hashi workflow, and assertions verify both return values and function call arguments.
relayer-cli/src/utils/hashi.ts (3)
85-147: LGTM - batch execution with proper chunking.The batch execution logic correctly processes messages in chunks of 20, filters for executable messages, normalizes data formats, and handles empty chunks. Based on learnings, transaction errors are allowed to propagate to upper layers.
162-209: LGTM - clean message status checking logic.The
toExecuteMessageandgetMessageStatusfunctions correctly implement the three-state model: threshold not met (returns null), executable (state withexecutable=true), and already executed (state withexecutable=false). On-chain calls are properly encoded/decoded.
220-265: LGTM - chunked log fetching with rate limiting.The
getAllMessageDispatchedLogsfunction implements proper chunked fetching with configurablechunkSizeandcooldownMsto prevent RPC rate limiting. The sorted return withtoBlockenables progress tracking. Per project patterns, RPC errors propagate to upper layers.relayer-cli/src/utils/botEvents.ts (1)
21-27: LGTM!The
HASHI_NOT_CONFIGUREDevent is a sensible addition to the Hashi executor event group, enabling proper logging/handling when Hashi configuration is missing.validator-cli/src/watcher.ts (5)
18-19: Verify RPC provider compatibility with the increased block limit.The
RPC_BLOCK_LIMITincrease from 100 to 1000 is a 10x change. Some RPC providers impose stricter limits oneth_getLogsor similar calls. Ensure your target providers (Infura, Alchemy, public nodes, etc.) support querying 1000 blocks in a single request to avoid runtime failures.The
CYCLE_DELAY_MSincrease to 2 minutes (from ~10s) significantly reduces polling frequency—ensure this aligns with the expected claim/challenge response time requirements.
144-151: LGTM!The gap handling logic correctly ensures the current claimable epoch (
currentEpoch - 1) is always in the watch list. The index increment after push ensures the newly added epoch is processed in the while loop.
192-201: LGTM!The expanded
getClaimsignature withnetworkandemitterparameters enables proper event emission for observability (e.g.,NO_CLAIM_FETCHED,CLAIM_MISMATCH). The object parameter pattern improves readability with this many arguments.
237-244: LGTM!The updated cleanup condition correctly prevents premature removal of the current claimable epoch and the latest tracked epoch. This ensures epochs remain monitored even when no active transactions are pending.
Note: After the gap handling logic (lines 147-151),
latestEpochwill equalcurrentEpoch - 1in most non-DEVNET cases, making the two conditions partially redundant. This is harmless but could be simplified if desired.
187-191: No action needed — both target networks support the "finalized" block tag.The code targets Arbitrum Sepolia (inbox) and Ethereum Sepolia (outbox), both of which support the "finalized" block tag. This is confirmed by both networks' RPC documentation and the fact that the codebase already uses "finalized" extensively in
arbToEthState.tswithout error handling. The concern about unsupported networks does not apply to this implementation.Likely an incorrect or invalid review comment.
