# Connecting Binance via Ed25519 Keys

### What is Ed25519 and why do you need it

Binance supports two types of API keys: standard (HMAC) and Ed25519.

Ed25519 is a cryptographic key based on an elliptic curve. It is more secure than the standard type: it is harder to brute-force, and request signing is faster.

The key difference from a regular API key: you generate the key pair (private + public) yourself inside MoonTrader, and only the public key is shared with Binance. The private key never leaves your computer.

### Section 1. Connecting via Client

#### Step 1. Create a Profile
