Multi-Chain Support

Create wallets on Bitcoin, Ethereum, Solana, and Tron with a consistent API interface.

HD Wallet Architecture

Hierarchical deterministic wallets allow you to generate unlimited addresses from a single seed.

Enterprise Security

Private keys are encrypted with AES-256 and stored in hardware security modules (HSMs).

Simple Integration

Create a wallet in seconds

Our API is designed to be intuitive. Create a new wallet with just a few lines of code and start receiving deposits immediately.

Wallet creation returns:

Address — The public address for receiving funds
Wallet ID — Unique identifier for API operations
Network — The blockchain network
Metadata — Your custom labels and tags

JavaScript

import { Relay } from '@relay/sdk';

const relay = new Relay('your-api-key');

// Create a new Ethereum wallet
const wallet = await relay.wallets.create({
  network: 'ethereum',
  label: 'customer-001',
  metadata: {
    userId: 'user_12345',
    purpose: 'deposit'
  }
});

console.log(wallet);
// {
//   id: "wallet_abc123",
//   address: "0x742d35Cc6634C0532925a3b844Bc...",
//   network: "ethereum",
