Sign in to send21

Get paid in crypto straight to your own wallet.

Non-custodial by design. send21 never holds keys or funds. It only prepares payment instructions that you review and sign in your own wallet. You are fully responsible for your keys and for verifying every transaction before signing.

Sign in

Phishing-resistant and passwordless. Your passkey (Face ID, Windows Hello, security key) never leaves your device, and send21 stores only its public key.
