Binance Auth REST private ed25519 example for the Siebly Binance SDK, with TypeScript source for exchange REST API and WebSocket integration, setup, and production SDK docs.

What This Example Covers

Binance authentication and request-signing example in TypeScript.

Source path: Binance/Auth/rest-private-ed25519.ts.
Example category: Auth.
Imports SDK symbols including MainClient.
Calls SDK methods such as getAccountInfo().

How To Use This Example

Start here for the specific request or stream pattern, then check the matching SDK guide for install, credentials, and operational notes.
For private or order-management examples, keep credentials in environment variables or a secret manager. Use read-only keys where possible, and check the execution mode reference before any exchange write path can run.

import { MainClient } from 'binance';

// Received after creating a new API key with a self-generated RSA public key on binance

// The self-generated RSA private key, this is never directly given to binance, but used to generate a signature
// Note: this MUST include the "BEGIN PRIVATE KEY" header so the SDK understands this is RSA auth
const ed25519PrivateKey = `
-----BEGIN PRIVATE KEY-----
lkmlkm123lkms1s12s+lkmlkm123lkms1s12s
-----END PRIVATE KEY-----
`;

const ed25519APIKey = 'lkmlkm123lkms1s12slkmlkm123lkms1s12slkmlkm123lkms1s12s';

const client = new MainClient({
  api_key: ed25519APIKey,
  api_secret: ed25519PrivateKey,
  beautifyResponses: true,

(async () => {
  try {
    console.log('private api call result: ', await client.getAccountInfo());
  } catch (e) {
