ONCHAIN AUTHORIZATION API
Turn onchain state into application permissions.
AccessVerdict gives backend applications a stable authorization layer over Base and Ethereum wallet and token state.
INPUT
Wallet plus policy
Your app sends the authenticated wallet and a saved access policy identifier.
ENGINE
Chain reads stay behind the authorization boundary
AccessVerdict evaluates ERC-20 balances, ERC-721 ownership, ERC-1155 balances and wallet allowlists through the same policy engine.
OUTPUT
Deterministic decisions for application code
The response separates conclusive allow/deny outcomes from verification errors and includes entitlements your application can map to features.
