Fetches all CCIP messages contained in a given commit batch. To be implemented for chains supporting CCIPVersion v1.6.0 and earlier

Type Parameters

Type Parameter
R extends { lane: { destChainSelector: bigint; onRamp: string; sourceChainSelector: bigint; version: CCIPVersion; }; log: { blockTimestamp: number; }; message: { sequenceNumber: bigint; } | { sequenceNumber: bigint; } | { sequenceNumber: bigint; } | { sequenceNumber: bigint; } | { sequenceNumber: bigint; } | { sequenceNumber: bigint; }; }

Parameters

Parameter	Type	Description
request	R	CCIPRequest to fetch batch for
range	Pick<CommitReport, "minSeqNr" | "maxSeqNr">	batch range { minSeqnr, maxSeqNr }, e.g. from CommitReport
opts?	{ page?: number; }	Optional parameters (e.g., page for pagination width)
opts.page?	number	-

Returns

Promise<R["message"][]>

Throws

CCIPMessageBatchIncompleteError if not all messages in range could be fetched

Example

TypeScript

const verifications = await dest.getVerifications({ offRamp, request })

---

getMessagesInRange()

getMessagesInRange(opts: LogFilter): AsyncIterableIterator<CCIPRequest<CCIPVersion>>

Defined in: chain.ts:825

Discover and decode CCIP messages within a block/slot/checkpoint range.

Parameters

Parameter	Type	Description
opts	LogFilter	LogFilter options (startBlock, endBlock, address, topics, page)

Returns

AsyncIterableIterator<CCIPRequest<CCIPVersion>>

Async iterator of CCIPRequest objects in native log order

Remarks

This is the range-scanning equivalent of getMessagesInTx. Results are yielded in native log order (block number + log index for EVM, slot order for Solana). Non-CCIP logs in the range are silently skipped.

On Solana, the address parameter is required (router program address). On EVM, it is optional but recommended for public RPCs that require address filtering.

Throws

CCIPChainFamilyUnsupportedError if a pre-v1.6 message is found on a non-EVM chain

Throws

CCIPLogsAddressRequiredError on Solana if address is not provided (thrown by underlying Chain.getLogs)

See

• getMessagesInBatch - Batch discovery by sequence number range
• getMessagesInTx - Per-transaction message discovery

Example

TypeScript

for await (const request of chain.getMessagesInRange({
  startBlock: 1000000,
  endBlock: 1001000,
  address: '0xOnRampAddress...', // optional on EVM
})) {

for (const req of requests) {
  console.log(`Message ID: ${req.message.messageId}`)

getTokenPrice()

getTokenPrice(_opts: { router: string; timestamp?: number; token: string; }): Promise<TokenPrice>

Defined in: chain.ts:1843

Fetch the on-chain USD price of a token from the FeeQuoter or PriceRegistry.

Parameters

Parameter	Type
_opts	{ router: string; timestamp?: number; token: string; }
_opts.router	string
_opts.timestamp?	number
_opts.token	string

Returns

Promise<TokenPrice>

Promise resolving to TokenPrice with the USD price per whole token.

Remarks

On EVM, the price contract is resolved via the Router's OnRamp: PriceRegistry for v1.2/v1.5 lanes, FeeQuoter for v1.6+ lanes. When timestamp is provided on EVM, the price is read at the block closest to that timestamp (requires archive node). On Solana and Aptos, the FeeQuoter is resolved directly from the Router config; timestamp is not yet supported and will be ignored.

Throws

CCIPNotImplementedError if not implemented for this chain family

Example

TypeScript

const { price } = await chain.getTokenPrice({
  router: routerAddress,
  token: linkAddress,
})
console.log(`LINK: $${price.toFixed(2)}`)

resolveExecuteOpts()

protected resolveExecuteOpts(opts: ExecuteOpts): Promise<{ input: ExecutionInput; offRamp: string; } & { forceBuffer?: boolean; forceLookupTable?: boolean; gasLimit?: number; heapFrameBytes?: number; tokensGasLimit?: number; }>

Defined in: chain.ts:1225

Resolves ExecuteOpts that may contain a messageId (API shorthand) into the canonical { offRamp, input } form required by generateUnsignedExecute.
