Features

Wallet Detection

if (window.cave) {
  console.log('Cave Wallet is installed!');
}

Account Management

// Get current account
const account = await wallet.getAccount();

// Listen for account changes
wallet.on('accountChanged', (newAccount) => {
  console.log('Account changed:', newAccount);
});

Transaction Signing

const tx = {
  to: 'g1recipient...',
  amount: '1000000ugnot',
};

const result = await wallet.signAndBroadcast(tx);

Best Practices

1. Always check wallet installation before attempting to connect
2. Handle rejections gracefully - users may decline connection
3. Display clear transaction info before requesting signatures
4. Listen for account changes to update UI accordingly
5. Test on testnet before mainnet deployment
