​
Supported Networks

The BlindPay SDK supports multiple blockchain networks for maximum flexibility:
  • Ethereum - The original EVM network
  • Base - Coinbase’s L2 network (recommended for low fees)
  • Arbitrum - High-performance L2 network
  • Polygon - Fast and low-cost transactions
  • Stellar - Built for financial applications
  • Tron - High throughput blockchain
  • Solana - Ultra-fast blockchain network

​
Supported Stablecoins

  • USDC - USD Coin by Circle
  • USDT - Tether USD
  • USDB - USD Base

​
Supported Fiat Currencies & Rails

  • USD (United States Dollar) - ACH, Wire, RTP
  • BRL (Brazilian Real) - PIX
  • MXN (Mexican Peso) - SPEI
  • COP (Colombian Peso) - ACH COP
  • ARS (Argentine Peso) - Transfers
  • International - SWIFT transfers

​
Response Format

All SDK methods return a consistent response format for predictable error handling: Success Response: 
{
  data: YourDataType,
  error: null
}
Error Response: 
{
  data: null,
  error: {
    message: "Error description"
  }
}
This pattern allows you to handle errors gracefully: 
const { data, error } = await blindpay.available.getRails();

if (error) {
  console.error('Operation failed:', error.message);
  return;
}

// data is fully typed and safe to use
console.log('Available rails:', data);

​
Requirements

  • Node.js >= 18.x
  • TypeScript 5.x (optional, but recommended)
