Sign in with your wallet

Signing proves you own the wallet. It moves no funds and costs no fee. You get a token to use as an API key.

Phantom needs Chrome, Brave or Edge: it no longer supports Firefox. On Firefox, use Solflare.

The lifetime and cap are part of the message you sign. Your balance doesn't expire when the token does.

Using an agent or script?

Agents and scripts sign the same challenge with a key. See the auth flow. Don't give an agent your main wallet: sign once here and give it a capped token.
