What is a digital signature wallet verification?

A digital signature is a secure way to prove that you own a self-hosted wallet, without needing to send any crypto. It’s one of the methods we use to verify wallet ownership, helping us meet regulatory requirements and keep your account secure.

This process involves connecting your wallet (using Reown, formerly WalletConnect) and signing a unique message we generate. The message is non-transactional: signing it doesn’t move any funds. It simply confirms that you control the private key for the address.
