XRPL Token Sniping

Monitor XRPL for new token launches, verify issuer flags for safety, and execute fast token buys while managing XRP reserves to minimize risk.

Detect New Tokens

Subscribe to Transactions

typescript

const ws = new WebSocket('wss://xlrps-1.xrpl.link/');

ws.send(JSON.stringify({
  command: 'subscribe',
  transactions: true
}));

// Watch for Payment transactions with new tokens
ws.onmessage = (msg) => {
  const tx = JSON.parse(msg.data);
  if (tx.TransactionType === 'Payment' && tx.Amount?.currency) {
    console.log('New token:', tx.Amount);
  }
};

Check Issuer Flags

typescript

// Key flags to audit before buying:
const flags = {
  lsfDisableMaster: 0x00080000,  // CANNOT mint more - SAFE
  lsfRipple: 0x00020000,         // Default ripple
  lsfDefaultRipple: 0x00040000,  // Trustline default
  lsfRequireAuth: 0x00010000      // Must be authorized
};

// SKIP if:
- lsfDisableMaster is NOT set (issuer can rug)
- No requireAuth (anyone can hold)

Execute Buy

typescript

const { Client, Wallet } = require('xrpl');
const client = new Client('wss://xrplcluster.com');

const tx = {
  TransactionType: 'Payment',
  Account: wallet.address,
  Destination: issuerAddress,
  Amount: {
    currency: tokenCode, // e.g., 'SYM123'
    issuer: issuerAddress,
    value: '100' // Amount to buy
  },
  DestinationTag: 1 // For tracking
};

const result = await client.submit(tx, { wallet });

Safety Checks

✅ MUST VERIFY:

1. lsfDisableMaster flag set (no more minting)
2. Contract ownership renounced
3. Liquidity added (check trustlines)
4. Not a honeypot (can sell after buying)

❌ SKIP IF:

• No audit
• No liquidity
• Non-renounced contract

Risk Profile

• High risk - Only trade what you can lose
• Always audit token flags before buying
• Keep XRP reserve for fees (~10 XRP)
