Sygna Travel Rule Compliance Integration

Sygna Integration (Travel Rule Compliance)

Sygna Bridge is a Travel Rule messaging platform from CoolBitX, popular in Asia (Taiwan, Japan, Korea) and among major exchanges (OKX, BitoPro, MaiCoin). If your audience or partners are Asian exchanges, Sygna provides better VASP coverage for that region.

API Integration

Sygna uses IVMS101 standard for formatting Travel Rule data — this is InterVASP Messaging Standard, adopted by most providers.

import { SygnaClient } from "@sygna/bridge-sdk";

const client = new SygnaClient({
  apiKey: process.env.SYGNA_API_KEY,
  baseUrl: "https://api.sygna.io/v2",
  privateKeyHex: process.env.SYGNA_PRIVATE_KEY, // for message signing
});

// Send Travel Rule data on withdrawal
async function sendTravelRuleData(withdrawal: Withdrawal): Promise<void> {
  const beneficiaryVASP = await client.getCurrencyId(withdrawal.destinationAddress);
  
  if (!beneficiaryVASP) return; // unhosted wallet
  
  const originatorData = {
    originator: {
      originatorPersons: [{
        naturalPerson: {
          name: [{
            nameIdentifier: [{
              primaryIdentifier: withdrawal.user.lastName,
              secondaryIdentifier: withdrawal.user.firstName,
              nameIdentifierType: "LEGL",
            }]
          }]
        },
        accountNumber: [withdrawal.fromAddress],
      }]
    },
    beneficiary: {
      beneficiaryPersons: [{ accountNumber: [withdrawal.destinationAddress] }]
    },
  };
  
  const callbackUrl = `${process.env.API_URL}/webhooks/sygna/callback`;
  
  await client.postPermissionRequest({
    data: client.encryptData(JSON.stringify(originatorData), beneficiaryVASP.encryptionKey),
    signature: client.signData(originatorData),
    expire_date: Math.floor(Date.now() / 1000) + 3600,
    callback_url: callbackUrl,
    transaction: {
      currency_id: withdrawal.asset,
      amount: withdrawal.amount.toString(),
      sender_address: withdrawal.fromAddress,
      recipient_address: withdrawal.destinationAddress,
    },
  });
}

Sygna vs Notabene

Choice between Sygna and Notabene depends on geography of VASP partners. For global coverage — integrate both through unified Travel Rule service. Sygna integration: 1-2 weeks.
