Developer Integration¶

1. Detection and Connection¶

Detect Phantom and request connection:

// Detect Phantom
const getProvider = () => {
  if ('phantom' in window) {
    const provider = window.phantom?.solana;
    if (provider?.isPhantom) {
      return provider;
    }
  }
  window.open('https://phantom.app/', '_blank');
};

// Connect wallet
const connectWallet = async () => {
  const provider = getProvider();
  try {
    const resp = await provider.connect();
    console.log('Public Key:', resp.publicKey.toString());
  } catch (err) {
    console.error('Connection rejected');
  }
};

2. Send Transaction¶

Build and send a Solana transaction:

import { Transaction, SystemProgram, LAMPORTS_PER_SOL } from '@solana/web3.js';

const sendTransaction = async () => {
  const provider = getProvider();
  const connection = new Connection('https://api.mainnet-beta.solana.com');

  const transaction = new Transaction().add(
    SystemProgram.transfer({
      fromPubkey: provider.publicKey,
      toPubkey: recipientPublicKey,
      lamports: 0.1 * LAMPORTS_PER_SOL,
    })
  );

  transaction.feePayer = provider.publicKey;
  transaction.recentBlockhash = (
    await connection.getLatestBlockhash()
  ).blockhash;

  const signed = await provider.signTransaction(transaction);
  const signature = await connection.sendRawTransaction(signed.serialize());
  await connection.confirmTransaction(signature);

  console.log('Transaction successful:', signature);
};

3. Sign Messages¶

Verify user identity:

const signMessage = async () => {
  const provider = getProvider();
  const message = `Login time: ${new Date().toISOString()}`;
  const encodedMessage = new TextEncoder().encode(message);

  const signedMessage = await provider.signMessage(encodedMessage, 'utf8');
  console.log('Signature:', signedMessage.signature);

  // Verify the signature
  const publicKey = provider.publicKey;
  const verified = nacl.sign.detached.verify(
    encodedMessage,
    signedMessage.signature,
    publicKey.toBytes()
  );
  console.log('Signature valid:', verified);
};

4. Event Listening¶

Listen for account and network changes:

const provider = getProvider();

// Listen for account changes
provider.on('accountChanged', (publicKey) => {
  if (publicKey) {
    console.log('Switched to account:', publicKey.toString());
  } else {
    console.log('Account disconnected');
  }
});

// Listen for network changes
provider.on('chainChanged', (chainId) => {
  console.log('Network switched:', chainId);
});

// Listen for disconnection
provider.on('disconnect', () => {
  console.log('Phantom disconnected');
});
