Pump.fun Direct Trading on Solana — Bypassing Jupiter for Faster Snipes

Why Direct Trading? When a token launches on Pump.fun, it trades on a bonding curve before graduating to Raydium. During this phase, Jupiter can't route to it. You need to interact with the bonding curve directly. The Bonding Curve Pump.fun uses a constant product bonding curve. The price increases as more tokens are bought. price = virtualSolReserves / virtualTokenReserves Direct Buy Implementation const { Connection , PublicKey , Transaction } = require ( ' @solana/web3.js ' ); async function buyOnPumpFun ( mintAddress , amountSOL , wallet ) { const conn = new Connection ( ' https://api.mainnet-beta.solana.com ' ); // Fetch bonding curve data const bondingCurve = await getBondingCurveAccount ( mintAddress ); // Calculate tokens received const tokensOut = calculateTokensOut ( amountSOL , bondingCurve . virtualSolReserves , bondingCurve . virtualTokenReserves ); // Apply slippage (e.g., 5%) const minTokens = tokensOut * 0.95 ; // Build transaction with Pump.fun program instruction cons
