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. ## 📖 Documentation Read more about Web3Auth Solana Provider in the [official Web3Auth Documentation](https://web3auth.io/docs/sdk/web/providers/solana#getting-a-provider-from-any-secp256k1-private-key). ## 💡 Features - Plug and Play, OAuth based Web3 Authentication Service - Fully decentralized, non-custodial key infrastructure - End to end Whitelabelable solution - Threshold Cryptography based Key Reconstruction - Multi Factor Authentication Setup & Recovery (Includes password, backup phrase, device factor editing/deletion etc) - Support for WebAuthn & Passwordless Login - Support for connecting to multiple wallets - DApp Active Session Management ...and a lot more ## 🔗 Installation ```shell npm install --save @web3auth-mpc/solana-provider ``` ## 🩹 Example ### `SolanaPrivateKeyProvider` ```ts 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` ```ts 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` ```ts 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 ```ts import { SolanaPrivateKeyProvider, SolanaWallet } from "@web3auth-mpc/solana-provider"; import type { SafeEventEmitterProvider } from "@web3auth-mpc/base"; const signSolanaMessage = async (provider: SafeEventEmitterProvider): Promise => { 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); })(); ``` Checkout the examples for your preferred blockchain and platform in our [examples repository](https://github.com/Web3Auth/examples/) ## 🌐 Demo Checkout the [Web3Auth Demo](https://demo-app.web3auth.io/) to see how Web3Auth can be used in your application. ## 💬 Troubleshooting and Support - Have a look at our [Community Portal](https://community.web3auth.io/) to see if anyone has any questions or issues you might be having.
