Web3Auth Solana Provider

Web3Auth is where passwordless auth meets non-custodial key infrastructure for Web3 apps and wallets. By aggregating OAuth (Google, Twitter, Discord) logins, different wallets and innovative Multi Party Computation (MPC) - Web3Auth provides a seamless login experience to every user on your application.

Web3Auth Solana Provider can be used to interact with wallet or connected Solana chain using RPC calls. This is a Solana chain compatible JRPC provider.

🔗 Installation

npm install --save @web3auth-mpc/solana-provider

🩹 Example

SolanaPrivateKeyProvider

import { SolanaPrivateKeyProvider } from "@web3auth-mpc/solana-provider";

const solanaPrivateProvider = await SolanaPrivateKeyProvider.getProviderInstance({
  chainConfig: {
    rpcTarget: "https://ssc-dao.genesysgo.net",
    chainId: "0x1", // hex chain id
    displayName: "solana",
    ticker: "SOL",
    tickerName: "Solana",
  },
  privKey: "user's private key",
});

SolanaWallet

SolanaWallet can be used with two types of providers:

1. web3auth.provider that you get after logging in with Web3Auth.
2. solanaPrivateProvider.provider that you get after passing user's private key to SolanaPrivateKeyProvider.

web3auth.provider

import { SolanaWallet } from "@web3auth-mpc/solana-provider";

const solanaWallet = new SolanaWallet(web3auth.provider);
const msg = Buffer.from("Signing Message", "utf8");
const result = await solanaWallet.signMessage(msg);
return result;

solanaPrivateProvider.provider

import { SolanaWallet } from "@web3auth-mpc/solana-provider";

const solanaWallet = new SolanaWallet(solanaPrivateProvider.provider);
const msg = Buffer.from("Signing Message", "utf8");
const result = await solanaWallet.signMessage(msg);
return result.toString();

General Example

import { SolanaPrivateKeyProvider, SolanaWallet } from "@web3auth-mpc/solana-provider";
import type { SafeEventEmitterProvider } from "@web3auth-mpc/base";

const signSolanaMessage = async (provider: SafeEventEmitterProvider): Promise<string> => {
  const solanaWallet = new SolanaWallet(provider as any);
  const msg = Buffer.from("Signing Message", "utf8");
  const result = await solanaWallet.signMessage(msg);
  return result.toString();
};

(async () => {
  // Assuming you're logged in with Web3Auth.
  const privateKey = await web3auth.provider.request({
    method: "solanaPrivateKey",
  });
  const solanaPrivateProvider = await SolanaPrivateKeyProvider.getProviderInstance({
    chainConfig: {
      rpcTarget: "https://ssc-dao.genesysgo.net",
      chainId: "0x1", // hex chain id
      displayName: "solana",
      ticker: "SOL",
      tickerName: "Solana",
    },
    privKey: privateKey,
  });
  const signedMessage = await signSolanaMessage(solanaPrivateProvider.provider);
})();
