Payments & USDC

const balance = await sdk.wallet.getBalances();
console.log(`USDC: $${(balance.usdc / 1_000_000).toFixed(2)}`);
console.log(`SOL: ${balance.sol}`);

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

// Step 1: Prepare (returns unsigned transaction)
const prepared = await sdk.wallet.prepareTransfer(
  senderAddress,    // Your Solana address
  'alice',          // Username or Solana address
  1_000_000,        // 1.00 USDC in minor units

// Step 2: Sign with your keypair
const tx = Transaction.from(Buffer.from(prepared.transaction, 'base64'));
tx.partialSign(keypair);
const signedTx = tx.serialize({ requireAllSignatures: false }).toString('base64');

// Step 3: Submit
const result = await sdk.wallet.submitTransfer(

console.log(`Sent! Signature: ${result.signature}`);

// Step 1: Prepare tip

// Step 2: Sign and submit (same as transfer)
// ...

// Step 3: Broadcast to global chat
