Whitepaper and roadmap
Overview
AgiCards turns a MetaMask Smart Account permission into a scoped capability card for an AI agent, enforced on chain. The agent gets a controlled power, today spending, and can use it only within the limits the user sets. Funds never leave the user's account.
How it works
1. Grant. The user approves one Advanced Permission (ERC-7715) in MetaMask: a daily USDC cap with an expiry, granted to the agent's session key. This also upgrades the user's account to an EIP-7702 smart account.
2. Enforce. The cap and expiry are checked by the account's caveat enforcer on chain, not by a server. The agent can never exceed them.
3. Redeem. A background agent redeems the delegation (ERC-7710) to run the action, for example an x402 USDC payment, on the user's behalf and inside the caveat.
4. Audit. Each execution is recorded to 0G storage, giving a verifiable trail.
Trust model
Non-custodial: funds stay in the user's MetaMask Smart Account. Every spend is enforced on chain on Base, and the card is revocable at any time. Revoking removes the permission immediately.
Capability model
A card is a capability primitive. The same permission model can scope any allowlisted on-chain action within limits, so payments are the first of many powers a card can grant.
