Class JitoIntegration

Jito Block Engine Integration Real Jito API for MEV-protected transaction bundles

Example

const jito = new JitoIntegration(client);

// Get tip account
const tipAccount = jito.getTipAccount('mainnet');

// Submit bundle
const bundle = await jito.submitBundle({
  transactions: [serializedTx1, serializedTx2],
  tipLamports: 1_000_000,
});

// Check status
const status = await jito.getBundleStatus(bundle.bundleId);
