Eternal Users Protocol

A user profiles protocol stored on Arweave, verified on Solana via compressed NFTs.

React Usage

Prerequisites

Ensure your app has Solana wallet adapter and required providers. EUP will utilize the useWallet hook. https://github.com/anza-xyz/wallet-adapter

function App() {
    return (
        <ConnectionProvider endpoint={endpoint}>
          <WalletProvider wallets={[]}>
              <WalletModalProvider>
                <OtherComponent />
              </WalletModalProvider>
          </WalletProvider>
        </ConnectionProvider>
    )
}

Create/Update User

Create or update a user profile via the update method. This will create a profile if one doesn't already exist or update existing. This flow consists of uploading metadata to Arweave then minting or updating the users profile NFT. Expect about three wallet popups (fund upload, sign upload, mint/update NFT)

import { useEup } from "eternal-users-protocol";

import { ConnectionProvider, WalletProvider } from '@solana/wallet-adapter-react';
import { WalletAdapterNetwork } from '@solana/wallet-adapter-base';
import { WalletModalProvider, WalletMultiButton } from '@solana/wallet-adapter-react-ui';
import { clusterApiUrl } from '@solana/web3.js';

async function OtherComponent() {
    // The network can be set to 'devnet', 'testnet', or 'mainnet-beta'.
    const network = WalletAdapterNetwork.Devnet;

    // You can also provide a custom RPC endpoint.
    const endpoint = useMemo(() => clusterApiUrl(network), [network]);

    // Initialize EUP
    const eup = useEup(endpoint);

    return (
        <ConnectionProvider endpoint={endpoint}>
            <WalletProvider wallets={[]}>
                <WalletModalProvider>
                    <WalletMultiButton />
                    <input type="text" onChange={eup.set.name}>
                    <input type="file" onChange={eup.set.image}>
                    <button onClick={eup.update}>Update</button>
                </WalletModalProvider>
            </WalletProvider>
        </ConnectionProvider>
    )
}
