Solana Chain Signatures Contract

The Solana Chain Signatures Contract provides an implementation of the abstract ChainSignatureContract for Solana-based blockchains using Anchor and Solana's Web3.js. It enables interaction with Chain Signatures programs deployed on Solana.

Usage

import { contracts, constants } from 'signet.js'
import { AnchorProvider, Wallet } from '@coral-xyz/anchor'
import { Connection, PublicKey, Keypair } from '@solana/web3.js'
 
const connection = new Connection('https://api.devnet.solana.com')
const wallet = new Wallet(/* Use your actual keypair here */ Keypair.generate())
const provider = new AnchorProvider(
  connection,
  wallet,
  AnchorProvider.defaultOptions()
)
 
const contract = new contracts.solana.ChainSignatureContract({
  provider,
  programId: new PublicKey(constants.CONTRACT_ADDRESSES.SOLANA.TESTNET_DEV),
})

With Custom Configuration

import { contracts, constants } from 'signet.js'
import type { ChainSignaturesProject } from 'signet.js/contracts/solana'
import { AnchorProvider, Wallet, type Idl } from '@coral-xyz/anchor'
import { Connection, PublicKey, Keypair } from '@solana/web3.js'
import customIdl from './custom-idl.json'
 
const connection = new Connection('https://api.devnet.solana.com')
const wallet = new Wallet(Keypair.generate())
const provider = new AnchorProvider(
  connection,
  wallet,
  AnchorProvider.defaultOptions()
)
 
const contract = new contracts.solana.ChainSignatureContract({
  provider,
  programId: new PublicKey(constants.CONTRACT_ADDRESSES.SOLANA.TESTNET_DEV),
  config: {
    rootPublicKey: 'secp256k1:...',
    requesterAddress: 'Dewq9xyD1MZi1rE588XZFvK7uUqkcHLgCnDsn9Ns4H9M',
    idl: customIdl as ChainSignaturesProject & Idl,
  },
})

Parameters

Parameter	Type	Description
`args`	`object`	Configuration options for the contract
`args.provider`	`AnchorProvider`	Anchor provider instance for interacting with Solana
`args.programId`	`string \| PublicKey`	The program ID of the deployed ChainSignatures program
`args.config?`	`object`	Optional configuration object
`args.config.rootPublicKey?`	`NajPublicKey`	Optional root public key; derived from program ID if not provided
`args.config.requesterAddress?`	`string`	Optional requester wallet address. If not provided, defaults to the wallet address. Fee payer is always the wallet address.
`args.config.idl?`	`ChainSignaturesProject & Idl`	Optional custom IDL. If not provided, the default ChainSignatures IDL will be used
