Function: networkInfo()

networkInfo(selectorOrIdOrName: string | number | bigint): NetworkInfo

Defined in: networks.ts:165

Converts a chain selector, chain ID, or chain name to complete network information

Resolves against the live SELECTORS table, so chains added to it at runtime (e.g. a local devnet) resolve like bundled ones.

Parameters

Parameter	Type	Description
selectorOrIdOrName	string | number | bigint	Can be: - Chain selector as bigint or numeric string - Chain ID as number, bigint or string (EVM: "1", Aptos: "aptos:1", Solana: genesisHash) - Chain name as string ("ethereum-mainnet")

Returns

NetworkInfo

Complete NetworkInfo object

Throws

CCIPChainNotFoundError if chain is not found

Example

TypeScript

import { networkInfo } from '@chainlink/ccip-sdk'

// By chain name
const sepolia = networkInfo('ethereum-testnet-sepolia')
console.log('Selector:', sepolia.chainSelector)

// By chain selector
const fuji = networkInfo(14767482510784806043n)
console.log('Name:', fuji.name) // 'avalanche-testnet-fuji'

// By chain ID
const mainnet = networkInfo(1)
console.log('Family:', mainnet.family) // 'EVM'
