Defined in: chain.ts:912

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

Parameters

Parameter	Type	Description
`opts`	{ `address?`: `string`; `endBefore?`: `string`; `endBlock?`: `number` \| `bigint` \| `"finalized"` \| `"latest"`; `page?`: `number` \| `bigint`; `startBlock?`: `number` \| `bigint`; `startTime?`: `number` \| `bigint`; `topics?`: (`string` \| `string`[] \| `null`)[]; `watch?`: `boolean` \| `AbortSignal`; }	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

Scan a block range on EVM

TypeScript

for await (const request of chain.getMessagesInRange({
  startBlock: 1000000,
  endBlock: 1001000,
  address: '0xOnRampAddress...', // optional on EVM
})) {
  console.log(`seqNr=${request.message.sequenceNumber} dest=${request.lane.destChainSelector}`)
}

getOffRampConfig()

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

Defined in: sui/index.ts:310

Fetch the full OffRamp configuration for a given source chain.

Parameters

Remarks

Returns a merged object containing every static (per-contract) and per-source field exposed by the underlying contract. Concrete subclasses preserve the contract-native field names and return richer objects than the OffRampConfig base interface declares — they may include extra fields available only on specific versions (e.g. EVM v2.0 exposes onRamps: string[]).

Overrides

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. Concrete subclasses (e.g. EVMChain) preserve the contract-native field names and return richer objects than the OnRampConfig base interface declares — they may include extra fields available only on specific versions.

Parameters

Parameter	Type	Description
`offRamp`	`string`	OffRamp contract address

getTokenPrice()

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

Defined in: chain.ts:2196

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)}`)

Inherited from

Chain.getTokenPrice

resolveExecuteOpts()

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

Defined in: chain.ts:1461

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; }>
