Get Quotes (V1)
const axios = require('axios');
async function getQuote(amountIn, path) {
const [tokenA, tokenB, tokenC] = path;
const url = `https://mainnet-api.saucerswap.fi/route?from=${tokenA}&to=${tokenB}&amount=${amountIn}`;
const response = await axios.get(url);
return response.data;
}

Arbitrage Logic
1. Check Prices
// Get prices for potential paths
const paths = [
['USDC', 'HBAR', 'USDC'],
['USDC', 'SAUCE', 'USDC'],
['HBAR', 'USDC', 'HBAR']
];
for (const path of paths) {
const out = await getQuote(1000, path);
const profit = out - 1000;
console.log(`${path.join(' → ')}: ${profit}`);
}
2. Execute Swap
// Via HashPack or direct contract call
const tx = new ContractExecuteTransaction()
.setContractId(poolAddress)
.setFunction("swap")
.setParameters([...]);
Safety Checks
- Slippage: Set min output = expected * 0.97
- Gas: Estimate network fees (tinybars)
- Pool Depth: Check liquidity before large trades
- Hedera Gossip: Account for network latency
Key Differences from EVM
- No EOA signatures: Must use Hedera native signing
- Network fees: Paid in tinybars (not gas)
- Transaction types: Use HAPI, not EVM
- Token format: Use
