The Travel Rule compliance architecture.

// S5 Transport — CCTP bridge call (code-enforced Gate)
const tx = await cctpBridge.depositForBurn(
  amount, destinationDomain, mintRecipient, burnToken
);

// S6 Authorization — OFAC screening gate (code-enforced)
const screenResult = await chainalysis.checkAddress(mintRecipient);
if (screenResult.sanctioned) throw new ComplianceError('OFAC_HIT', 'S6');

// S7 Settlement — on-chain finality monitor
const receipt = await provider.waitForTransaction(tx.hash, 1);
assert(receipt.status === 1, 'Settlement failed at S7');

// S8 Finality — Travel Rule obligation (policy-enforced)
await travelRuleProvider.transmitPII({
  originator: { name, account, institution },
  beneficiary: { name, account, institution },
  txHash: tx.hash,
  amount, asset: 'USDC',
});
