Contract Addresses

All the necessary constants to interact with the Sig Network are exported from the constants.ts file.

Using the Constants in your code

You can import and use them in your code as follows:

import { utils } from 'signet.js'
 
const evmTestnetAddress = utils.constants.CONTRACT_ADDRESSES.ETHEREUM.TESTNET
 
console.log(evmTestnetAddress) // '0x83458E8Bf8206131Fe5c05127007FA164c0948A2'
 
const testnetPublicKey = utils.constants.ROOT_PUBLIC_KEYS.TESTNET
 
console.log(testnetPublicKey) // 'secp256k1:3Ww8iFjqTHufye5aRGUvrQqETegR4gVUcW8FX5xzscaN9ENhpkffojsxJwi6N1RbbHMTxYa9UyKeqK3fsMuwxjR5'
