Pump.fun Integration

Working with Pump.fun creator vaults.

Fee Flow

1. Token trades → fees accumulate in Pump.fun vault

2. Collection → fees move to Claimr PDA

3. Withdrawal → funds transfer to user's wallet

Vault Derivation

import { PublicKey } from '@solana/web3.js';

const PUMP = new PublicKey('6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P');

function getCreatorVault(creator: PublicKey): PublicKey {
  const [vault] = PublicKey.findProgramAddressSync(
    [Buffer.from('creator-vault'), creator.toBuffer()],
    PUMP
  );
  return vault;
}

// Derive vault for a Claimr PDA
const pda = getClaimrAddress('44196397');
const vault = getCreatorVault(pda);

Checking Vault Balance

const balance = await connection.getBalance(vault);
console.log(`${balance / 1e9} SOL`);

The API returns both balances in a single call:

curl "https://claimr.app/api/wallet/lookup?handle=someone"
# balance.vault contains uncollected fees

Triggering Collection

curl -X POST https://claimr.app/api/collect \
  -H "Content-Type: application/json" \
  -d '{"twitterId": "44196397"}'

This is a permissionless operation. Funds are transferred from the vault to the PDA.
