SaucerSwap Arbitrage

Overview

SaucerSwap is the main DEX on Hedera. Triangular arbitrage: profit from price differences between 3 tokens.

Key Contracts (Mainnet)

• SaucerSwap V1: 0xcaec9706a4622D356d2D3aEd8f8D40c51f0C0dF
• SaucerSwap V2: 0xA6F4E11E5D8A3F62A7D4E3E6B1E7F3C9E8F2A1B4

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;
}

Token Addresses (Hedera)

• HBAR: 0.0.1000 (wrapped: 0x... in EVM format)
• USDC: 0.0.456719
• USDT: 0.0.456720
• ETH: 0.0.456721
• WBTC: 0.0.456722
• SAUCE: 0.0.456723

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

1. Slippage: Set min output = expected * 0.97
2. Gas: Estimate network fees (tinybars)
3. Pool Depth: Check liquidity before large trades
4. 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 0.0.xxxxx not 0x...
