Implementation Steps

Seven steps to build global cross-border settlement infrastructure.

1
Configure Multi-Currency Stablecoins

Enable eUSD, eEUR, and eGBP for your platform. Configure wallets and treasury management for each currency.

// Enable multi-currency support
const currencies = ['eUSD', 'eEUR', 'eGBP'];
for (const currency of currencies) {
  await stablecoins.configs.enable({
    asset: currency,
    autoMint: true,
    autoRedeem: true,
    chains: ['ethereum', 'polygon']
  });
}
2
Set Up FX Infrastructure

Integrate reForge for instant currency conversion. Configure rate limits and slippage tolerance.

// Execute cross-border FX
const fx = await reForge.convert({
  from: 'eEUR',
  to: 'eUSD',
  amount: 100000, // 1,000 EUR
  slippageTolerance: 0.001
});

console.log({
  rate: fx.rate, // e.g., 1.085 USD per EUR
  amountReceived: fx.amountReceived, // ~108,500 cents
  fee: fx.fee,
  settlementTime: '10-15 seconds'
});
3
Implement Instant Currency Conversion

Build user flow for currency selection and conversion. Show real-time rates and estimated fees.

  • Real-time rate display
  • Fee breakdown transparency
  • Instant settlement confirmation
4
Add Open Banking for Local On/Off-Ramps

Connect OpenFinance for region-specific payment rails: SEPA in EU, ACH in US, Faster Payments in UK.

// Create region-specific payment account
const account = await openfinance.accounts.create({
  region: 'EU', // or 'US', 'UK'
  currency: 'EUR',
  type: 'virtual_iban',
  holder: { name: 'John Doe', country: 'DE' }
});

// For US users
const usAccount = await openfinance.accounts.create({
  region: 'US',
  currency: 'USD',
  type: 'ach_account',
  holder: { name: 'Jane Smith', country: 'US' }
});
5
Configure Compliance Per Region

Implement region-specific KYC/AML flows. Configure limits and requirements per jurisdiction.

  • EU: GDPR compliance + SEPA regulations
  • US: FinCEN compliance + state-level requirements
  • UK: FCA compliance + Faster Payments
6
Test Cross-Border Flows

Run comprehensive testing covering all currency pairs and regions.

  • Test EUR → USD conversion and settlement
  • Test GBP → EUR conversion and settlement
  • Test local on-ramps (SEPA, ACH, Faster Payments)
  • Test local off-ramps per region
  • Verify compliance per jurisdiction
7
