GET SET UP

Two doors

A human creates the key and sets the limits. The agent never signs in — it reads a different rendering of this same site.

I'M A HUMAN

You hold the boundary

1Sign in — no card details, no company needed. Your wallet is ready the moment you do.
2Fund it with USDC on Base, then create a Passport Key with a spending limit.
3Connect your agent — a checklist inside walks you through it.

Google sign-in only — we never see your password, and we ask for no personal details beyond your email.

A key pasted into a chat dies seconds after first use. One key, one machine.
