Parameters

Parameter	Type	Description

Defined in: chain.ts:933

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

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"][]>

Array of messages in the batch

Throws

CCIPMessageBatchIncompleteError if not all messages in range could be fetched

Example

TypeScript

const verifications = await dest.getVerifications({ offRamp, request })
const messages = await source.getMessagesInBatch(request, verifications.report)

Chain.getMessagesInBatch

getMessagesInRange()

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

Defined in: chain.ts:869

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
})) {

}

getOffRampConfig()

getOffRampConfig(offRamp: string, sourceChainSelector: bigint): Promise<{ on_ramp: string; onRamps: string[]; router: string; sourceChainSelector: bigint; typeAndVersion: string; }>

Defined in: aptos/index.ts:325

Fetch the full OffRamp configuration for a given source chain.

Parameters

Parameter	Type	Description

Parameters

Parameter	Type	Description

`_sourceChainSelector`	`bigint`	Source chain selector

Returns

Promise<string[]>

Merged OnRamp config — at minimum router, type, version, typeAndVersion.

Remarks

Returns a merged object containing every static (per-contract) and per-destination field exposed by the underlying contract.

Example

TypeScript

const [onRamp] = await dest.getOnRampsForOffRamp(offRampAddress, sourceSelector)
console.log(`OnRamp: ${onRamp}`)

Inherited from

Chain.getOnRampsForOffRamp

getTokenPrice()

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

Defined in: aptos/index.ts:894

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

Parameters

Parameter	Type	Description

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.

Overrides

Chain.getTokenPrice

resolveExecuteOpts()

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

Defined in: chain.ts:1326

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

When opts already contains input the method is a no-op and returns it unchanged. When opts contains only a messageId it calls apiClient.getExecutionInput and merges the result back with any extra opts fields (e.g. gasLimit). If opts.gasLimit is undefined and estimateReceiveExecution is available, try to estimate gasLimitOverride

Parameters

Parameter	Type
`opts`	`ExecuteOpts`

Returns

Promise<{ input: ExecutionInput; offRamp: string; } & { forceBuffer?: boolean; forceLookupTable?: boolean; gasLimit?: number; tokensGasLimit?: number; }>

buildMessageForDest()

static buildMessageForDest(this: ChainStatic, message: MessageInput): AnyMessage

Defined in: chain.ts:1872

Returns a copy of a message, populating missing fields like extraArgs with defaults. It's expected to return a message suitable at least for basic token transfers.

Parameters

Parameter	Type	Description
`this`	`ChainStatic`	-
`message`	`MessageInput`	AnyMessage (from source), containing at least `receiver`.

Returns

AnyMessage

A message suitable for sendMessage to this destination chain family.

Remarks

V3 (GenericExtraArgsV3) is auto-detected when any V3-only field is present (e.g. finality, ccvs, ccvArgs, executor, executorArgs, tokenReceiver, tokenArgs). Otherwise defaults to V2 (EVMExtraArgsV2).

Throws

CCIPArgumentInvalidError if extraArgs contains unknown fields for the detected version.
