AI agents need to make autonomous payments, but if you give them direct wallet access, they can drain your funds. Custodial solutions create liability and trust issues. Building custom controls takes weeks.
## The Solution
A two-gate enforcement model:
1. *Gate 1 (Validate)*: Agent requests payment → Policy engine checks limits → Issues single-use authorization token
2. *Gate 2 (Verify)*: Before signing → Verify token + check for tampering → Only then sign transaction
Your keys never leave your infrastructure. Policy enforcement happens before signing.
Currently demonstrated with Tether WDK on Ethereum, but the wrapper pattern works with any wallet SDK.
