Highlights

• EVM: read multi-token pools with a { token } option; preflights catch paused or incomplete lanes
• EVM: ERC-8056 (Scaled UI Amount) tokens: uiMultiplier, toUIAmount/fromUIAmount; CLI shows UI amounts
• Solana: 2.0 Routers serving 1.6 and 2.0 lanes side by side; new lane --lane-version
• CCIP 2.0: getVerifications composes missing USDC/LBTC verifier data from issuer attestations
• CLI: send/show --wait poll pending USDC/LBTC attestations (CCTP v2 too)
• EVM: send preflight simulates source pool lockOrBurn, catching hook, blocklist and curse reverts before signing
• SDK: tokens without decimals() get their decimals from their pool, or from the chain default
• CCT-SDK (EVM): pool query ops, simulateEVMTx, lockbox ownership, CrossChainPoolToken and more deployable pool types
• Canton: CantonChain uses the dApp SDK provider; CCT-SDK registry pool ops
• Sui: gRPC endpoint support, because public fullnodes no longer serve JSON-RPC
• Fixes: show --no-api executions on Arbitrum Nitro chains; faster Solana OffRamp discovery; HTTP 429 errors are retried
• ⚠️ Breaking: discoverOffRamp takes the lane, and cct/evm exports only the public ops

New Contributors

• @rodrigombsoares made their first contribution in #501

Full Changelog: v1.16.0...v1.16.1

Highlights

• CCT-SDK: full SiloedLockReleaseTokenPool lifecycle:
  • deploy it at v2.0.0 and bind per-lane lockboxes: configureSiloedLockboxes, getSiloedLockbox, getAllSiloedLockboxConfigs
  • manage v1.6.x silos: provideSiloedLiquidity, withdrawSiloedLiquidity, setSiloRebalancer, updateSiloDesignations, with the isSiloed/getChainRebalancer/getAvailableTokens reads
• CCT-SDK: operations resolve on-chain state themselves — applyChainUpdates and registerAdmin take a single version-less params shape (pool/module version detected on-chain), AdvancedPoolHooks ops accept a pool's address and resolve its hooks, Solana ops resolve the pool program from tokenAddress, and Canton ops derive pool type, owners and TokenAdminRegistry from the ledger
• CCT-SDK: unified prepare operation lifecycle (validation + parsing in one hook), typed CCT errors importable from the SDK root, and pool-type registries exported — EVM DEPLOYABLE_TOKEN_POOL_TYPES and Solana SOLANA_TOKEN_POOL_TYPES with type guards, ready for runtime validation and things like z.enum(...)
• Solana: CCIP 2.0 manualExec — 2.0 pool IDL decoding, faster-than-finality rate limits and per-chain finality surfaced in pool reads, allowlisted lanes consistently reported as unsupported (so getFee and sendMessage always agree, and quotes no longer need sender), and separate buffering/execution stages so oversized manual executions can be staged unsigned (Ledger-friendly)
• EVM: the nonce cache no longer replaces pending or in-flight transactions (TOB-CLCCT-12): safe rollback on inconclusive failures, and no re-prompt after a user rejection
• EVM: getLogs honors RPC-stated block-range limits below 100 blocks (e.g. Alchemy's free plan), fixing ccip-cli show --wait on such endpoints
• EVM: admin-transfer ops (beginDefaultAdminTransfer/accept/cancel) now also work on v1 FactoryBurnMintERC20 tokens
• Canton: per-service HTTP protocol selection, with automatic h2 → HTTP/1.1 fallback

Full Changelog: v1.13.0...v1.14.0

Highlights

• Performance: Fixed several memory leaks and spikes, which hindered ccip-sdk usage on long-lived, continuously polling services (e.g. through chain.getLogs)
• Tooling: migrated to TypeScript 7 and Oxlint (from eslint)
• SDK: chain.getLogs gain a new filter: since, which receives a ChainLog from a previous call, and can then resume from it (i.e. fetching logs since this given cursor) more efficiently in many chains than the usual startBlock/startTime

What's Changed

• fix: caches by @andrevmatos in #366
• feat: getLogs since resume hint by @andrevmatos in #367
• test: classify networked suites and lock live-network runs by @andrevmatos in #372

• EVM: gracefully handle RPCs limiting the number of topics filters in getLogs
• EVM: improve USDCTokenPoolProxy 2.0.0 multiple getPools() support
• Aptos: support multiple topics in getLogs
• Aptos: always format addresses as short hex (strip leading zeros)

• chore: prepare v1.12 release by @andrevmatos in #364

New Contributors

• @friedemannf made their first contribution in #355

Full Changelog: v1.11.1...v1.12.0

Highlights

• Destination-denominated amounts in checkExecute are now compared consistently across chains.
• Sui SuiExtraArgsV1 codec now correctly round-trips to/from Solana.
• Aptos typeAndVersion now accepts a bare package address.

What's Changed

• fix(aptos): accept bare package address in typeAndVersion by @aelmanaa in #345
• Fix/check execute decimals by @aelmanaa in #346
• sui: fix SuiExtraArgsV1 codec to/from solana by @andrevmatos in #351
• fix(evm): no execution gas for token-only transfers by @aelmanaa in #348

Highlights

• SDK: sendMessage and execute methods now accept opts.txGasLimit, skips estimation
• CLI: send and manual-exec --tx-gas-limit option to force gas limit for txs
• SDK/CLI: add q free-text filter to searchMessages and -q to search messages; matches token and pool addresses, tx hashes, messageId, sender and receiver
• SDK: searchAllMessages accepts options.cursor to resume from a previous page
• CLI: search messages --cursor resumes an earlier run; when --limit caps the results, the next cursor is printed to stderr
• SDK/CLI: CCIPAPIClient.getLaneLatency accepts options.sourceTokenAddress, exposed as lane-latency --source-token
• SDK: Breaking: lane latency INSUFFICIENT_DATA now throws CCIPLaneLatencyInsufficientDataError instead of CCIPHttpError
• SDK: estimateReceiveExecution now preflights the whole delivery pre-send: requested finality via the destination OffRamp's getCCVsForMessage, OffRamp lane gates, inbound rate limits, and, for token transfers, each destination pool's releaseOrMint
  • catches unregistered tokens, mis-wired source pools, missing mint/burn authority, RMN curses and insufficient liquidity, which previously only surfaced after the message stranded on the destination
  • source pools are simulated too, so the check consumes the same post-fee amount and destPoolData the OnRamp would emit
  • new simulateReleaseOrMint, simulateLockOrBurn, classifyPoolRevert, isTransientReleaseOrMintRevert, and errors CCIPDestExecutionRevertError, CCIPDestSimulationUnavailableError, CCIPSourcePoolRevertError
• CLI: send warns and continues when the preflight is inconclusive (destination RPC failure, attestation-consuming pool) instead of failing; --estimate-gas-limit/--only-estimate still make it fatal
• CLI: send --only-ccvs prints the destination-required CCV set (requiredCCVs, optionalCCVs, optionalThreshold) and exits, without sending
• SDK: getRequiredCCVs exported to read that set programmatically, plus encodeMessageV1/encodeTokenTransferV1 for the message encoding it uses
• EVM: getOffRampConfig now also returns rmn, when the OffRamp's RMNProxy is set
