DEX Auto-Routing

TrenchTools automatically detects which DEX a token is traded on and routes swaps accordingly. You never need to manually select a DEX.

How It Works

When you paste a token contract address (CA), the system:

1. Derives the PumpFun bonding curve PDA from the token mint
2. Fetches the account data from chain
3. Checks the complete flag at byte offset 48
4. If the bonding curve exists and complete === false → PumpFun (still on bonding curve)
5. If the bonding curve doesn't exist or complete === true → Jupiter (graduated to DEX)

// Simplified detection logic
const bondingCurve = derivePumpFunBondingCurve(tokenMint)
const accountInfo = await connection.getAccountInfo(bondingCurve)

if (accountInfo && accountInfo.data[48] === 0) {
  // Token is on PumpFun bonding curve
  return 'pumpfun'
} else {
  // Token has graduated or isn't PumpFun
  return 'jupiter'
}

Supported DEXes

DEX	Status	API	Used For
Jupiter	Fully implemented	Jupiter Quote + Swap API	Post-graduation tokens, any Solana token
PumpFun	Fully implemented	PumpPortal API	Pre-graduation bonding curve tokens
Raydium	Stubbed	—	Future
Meteora	Stubbed	—	Future

DEX Abstraction Layer

All DEX integrations follow the same interface:

interface DexSwapper {
  getQuote(inputMint: string, outputMint: string, amount: number, config: DexConfig): Promise<Quote>
  executeSwap(quote: Quote, wallet: Keypair, config: DexConfig): Promise<SwapResult>
}

This means all components (Sniper, Volume, Bot Groups, Treasury) use the same swap logic without caring about which DEX is underneath.

PumpFun Specifics

• Buy amounts: Specified in SOL (human-readable)
• Sell amounts: Specified in tokens (human-readable, divide raw by 10^decimals)
• Slippage: Percentage (not basis points)
• Fee reserve: 0.01 SOL reserved for rent/fees on buys
• API: PumpPortal API (no API key required)

Jupiter Specifics

• Amounts: Specified in lamports (raw integer)
• Slippage: Basis points (100 = 1%)
• API key: Optional but recommended for rate limits
• Priority fees: Configurable for transaction priority
