ClawPay 🦞

Send money privately. Recipient sees funds from Railgun - can't trace back to you.

Just Run It

Prerequisites: You need a wallet private key with USDT on BSC.

Save this as send-private.mjs and run with node send-private.mjs:

// send-private.mjs - Copy this entire file and run it
import { Wallet, JsonRpcProvider, Contract, parseUnits } from 'ethers';

// ============ CONFIGURE THESE ============
const PRIVATE_KEY = process.env.WALLET_KEY || '0xYOUR_PRIVATE_KEY';
const RECIPIENT = '0xRECIPIENT_ADDRESS';
const AMOUNT = '0.10';  // USDT amount
// =========================================

const API = 'https://clawpay.dev';
const BSC_RPC = 'https://bsc-dataseed.binance.org/';
const USDT = '0x55d398326f99059fF775485246999027B3197955';
const SIGN_MSG = 'b402 Incognito EOA Derivation';

async function sendPrivate() {
  const provider = new JsonRpcProvider(BSC_RPC);
  const wallet = new Wallet(PRIVATE_KEY, provider);
  const myAddress = wallet.address;

  console.log('Sending', AMOUNT, 'USDT privately to', RECIPIENT);
  console.log('From wallet:', myAddress, '\n');

  // 1. Sign message
  console.log('1. Signing...');
  const signature = await wallet.signMessage(SIGN_MSG);

  // 2. Get invoice address
  console.log('2. Getting invoice...');
  const invoiceRes = await fetch(
    API + '/invoice?eoa=' + myAddress + '&signature=' + encodeURIComponent(signature)
  );
  const { invoiceAddress } = await invoiceRes.json();
  console.log('   Invoice:', invoiceAddress);

  // 3. Transfer USDT to invoice
  console.log('3. Transferring USDT to invoice...');
  const usdt = new Contract(USDT, ['function transfer(address,uint256) returns (bool)'], wallet);
  const tx = await usdt.transfer(invoiceAddress, parseUnits(AMOUNT, 18));
  console.log('   TX:', tx.hash);
  await tx.wait();

  // 4. Execute private transfer
  console.log('4. Executing private transfer...');
  const transferRes = await fetch(API + '/transfer', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      eoa: myAddress,
      signature,
      recipient: RECIPIENT,
      amount: AMOUNT,
      token: 'USDT'
    })
  });
  const result = await transferRes.json();

  if (result.transferId) {
    console.log('\n✓ SUCCESS!');
    console.log('Transfer ID:', result.transferId);
    console.log('Status:', result.status);
    console.log('\nRecipient gets funds from Railgun in ~60 seconds.');
    console.log('They CANNOT see your wallet address.');
    console.log('\nCheck status: curl ' + API + '/status/' + result.transferId);
  } else {
    console.log('Error:', result.error);
  }
}

sendPrivate().catch(console.error);

Run it:

npm install ethers
WALLET_KEY=0xYourPrivateKey node send-private.mjs

API Reference

Base URL: https://clawpay.dev

POST /transfer

{
  "eoa": "0xYourAddress",
  "signature": "0xSignedMessage...",
  "recipient": "0xRecipientAddress",
  "amount": "1.00",
  "token": "USDT"
}

Response:

{
  "transferId": "tx_123...",
  "status": "pending",
  "message": "Transfer initiated"
}

Status flow: pending → shielding → proving → complete

No Private Key? Use Bankr Wallet

If you're an agent without direct wallet access, use Bankr:

// 1. Get your wallet from Bankr
const bankrWallet = await bankr.getWallet();

// 2. Sign the ClawPay message
const signature = await bankr.signMessage('b402 Incognito EOA Derivation');

// 3. Use signature with ClawPay API
// (same flow as above)

Supported Tokens (BSC)

Need Gas?

curl -X POST https://clawpay.dev/faucet \
  -H "Content-Type: application/json" \
  -d '{"address": "0xYourAddress"}'
