Just shipped direct Pump.fun bonding curve trading in @solscanitbot — a free Solana trading bot on Telegram.
The Speed Problem
When a new token launches on Pump.fun, every millisecond counts. The standard route goes:
- Detect new token
- Call Jupiter Quote API
- Call Jupiter Swap API
- Sign + send transaction
That's 2-3 HTTP round trips. By the time your transaction lands, the price has already pumped.
The Fix: Direct Bonding Curve
Now the bot detects Pump.fun tokens and trades directly against the bonding curve program (6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P). No Jupiter middleman:
- Detect new token
- Read bonding curve state on-chain
- Build + sign buy instruction locally
- Send via Jito for MEV protection
One round trip. The transaction is built locally using the constant product formula from the bonding curve's virtual reserves.
How It Works
Every Pump.fun token has a bonding curve PDA derived from the mint. We read the account data to get:
-
virtualSolReservesandvirtualTokenReserves— the AMM pricing -
completeflag — whether the token has graduated to PumpSwap
If not graduated, we build a buy instruction with the correct discriminator, calculate expected tokens from the reserves, and submit directly.
If graduated, we fall back to Jupiter (which routes through PumpSwap/Raydium).
Smart Routing
The bot now has automatic routing:
- Pump.fun bonding curve → Direct buy (fastest)
- PumpSwap/Raydium → Jupiter with priority fees
- Any other DEX → Jupiter with priority fees
All routes use Jito MEV protection to prevent sandwich attacks.
