# KyberSwap Arbitrage ## Overview Triangular arbitrage: profit from price differences between 3 tokens (e.g., USDC → ETH → USDT → USDC) ## Key Contracts (Base Mainnet) - **Router**: `0x6131B5fae19EA4f9D964eAc0408E4408b2a37dD8` - **Factory**: `0x5F1dddbf348aC2BEbe18559BF0eDE9D3fE6ce35f` ## Core Logic ### 1. Get Quotes ```typescript const router = new ethers.Contract(routerAddr, routerABI, provider); // Get amounts out for exact input const [amountOut] = await router.getAmountsOut( amountIn, // Wei amount [tokenA, tokenB, tokenC] // Path ); ``` ### 2. Calculate Profit ``` profit = finalAmount - initialAmount - gasCosts ``` ### 3. Execute Swap ```typescript const tx = await router.swapExactTokensForTokens( amountIn, amountOutMin, path, recipient, deadline ); ``` ## Token Addresses (Base) - **USDC**: `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` - **USDT**: `0xfde4C96c85940E8F44A6D8d5e4fD4f4C4f9D8E8` - **ETH**: `0x4200000000000000000000000000000000000006` - **WETH**: `0x4200000000000000000000000000000000000006` ## Arbitrage Pairs (Base) Common triangular paths: - USDC → ETH → USDC - USDC → WETH → USDT → USDC - USDT → ETH → USDC → USDT ## Safety Checks 1. **Slippage**: Set `amountOutMin` = output * (1 - slippage%) 2. **Gas**: Estimate gas, ensure profit > gas 3. **Max Price Impact**: Check pool reserves before large trades 4. **Renounced Contracts**: Only trade tokens with renounced ownership ## Risk Profile - **Aggressive** but audit-first - Skip all non-renounced contracts - Check for honeypot tokens
