Subscribe to Price Signals

import { SignalClient } from '@taifoon/sdk/signals';

const signals = new TaifoonSignals({
  apiKey: process.env.TAIFOON_API_KEY
});

// Subscribe to ETH/USDC price across chains
await signals.subscribe('price', {
  pair: 'ETH/USDC',
  chains: [1, 42161, 8453, 10],  // Ethereum, Arbitrum, Base, Optimism
  interval: '1s',  // 1 second updates
});

// Listen for price updates
signals.on('price', (signal) => {
  console.log(`Chain ${signal.chainId}: $${signal.price}`);
  console.log(`Proof: ${signal.proof}`);  // Cryptographic proof

  // Check for arbitrage opportunity
  checkArbitrage(signal);
});

Execute Verified Arbitrage

async function checkArbitrage(signal) {
  const { chainId, price, proof } = signal;

  // Compare with other chains
  const opportunity = findBestOpportunity(price, chainId);

  if (opportunity.profitBps > 50) {  // >0.5% profit
    // Execute cross-chain arbitrage
    const tx = await arbitrageContract.executeArbitrage({
      sourceChain: chainId,
      targetChain: opportunity.targetChain,
      amount: parseEther('1.0'),
      proof: proof,  // ✅ Cryptographically verified price
    });

    console.log('Arbitrage executed:', tx.hash);
  }
}

// ✅ Proof guarantees:
// - Price is accurate (can't be manipulated)
// - Timing is verifiable (exact block timestamp)
// - Execution can be proven on-chain

You're Trading!
