Solana Wallet Adapter Example

The CrossmintSolanaWalletAdapter is fully compatible with @solana/wallet-adapter and can be dropped into place like so:

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

import {CrossmintSolanaWalletAdapter} from "@crossmint/connect"

// Default styles that can be overridden by your app
require('@solana/wallet-adapter-react-ui/styles.css');

export const Wallet: FC = () => {
    // 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]);

    const wallets = useMemo(
        () => [
            new CrossmintSolanaWalletAdapter({})
        ],
        []
    );

    return (
        <ConnectionProvider endpoint={endpoint}>
            <WalletProvider wallets={wallets} autoConnect>
                <WalletModalProvider>
                    <WalletMultiButton />
                    <WalletDisconnectButton />
                </WalletModalProvider>
            </WalletProvider>
        </ConnectionProvider>
    );
};

EVM Wallet Connect Example

The following is an example of connecting to a user's Crossmint Ethereum account using the CrossmintEVMWalletAdapter

import {
  BlockchainTypes,
  CrossmintEnvironment,
  CrossmintEVMWalletAdapter,
} from "@crossmint/connect";

import { useState } from "react";

export default function YourCustomConnectButton() {
  const [address, setAddress] = useState<string | undefined>(undefined);

  async function connectToCrossmint() {
    // Initialize the Crossmint connect.
    const _crossmintConnect = new CrossmintEVMWalletAdapter({
      chain: BlockchainTypes.ETHEREUM, // BlockchainTypes.ETHEREUM || BlockchainTypes.POLYGON. For solana use BlockchainTypes.SOLANA
    });

    // Ask the user to sign in and give access to their publicKey
    const address = await _crossmintConnect.connect();

    // If the user successfully connects to Crossmint, the address will be returned.
    if (address) {
      setAddress(address);
    }
  }

  return (
    <button
      onClick={connectToCrossmint}
      className="px-6 py-2 font-semibold text-black bg-white rounded-md"
    >
      {address ? address.slice(0, 6) + "..." : "Connect"}
    </button>
  );
}
