AgiCards

AgiCards gives an AI agent its own spending card, with strict rules you set. The agent can pay for things on its own, and your main wallet is never touched.

The problem

AI agents are starting to do real work. They buy tools, call paid APIs, and run tasks for you all day.

But there is no safe way to let them spend money. You either hand over your private key and risk losing everything, or you approve every payment by hand, which defeats the whole point.

The idea

You create a permission card for your agent. A card is a clear, limited license to spend.

You set the rules for each card: how much it can spend per day, how much per single action, which apps it can use, and when it expires.

Once you approve those rules, the agent acts on its own. It can never go past the limits you set.

Why it is safe

The limits are not based on trust, and they are not enforced by our servers. They are enforced by the blockchain itself.

When you make a card, MetaMask asks you to approve one permission. That permission holds your rules.

Every time the agent tries to spend, the rules are checked on chain. If it goes over the daily cap, or the card has expired, the blockchain rejects the payment. There is no way around it.

How a card works

1. You describe what you want in plain words. For example: pay for cloud compute, one dollar a day, twenty cents per charge, for seven days.

2. AgiCards turns that into a real permission, and MetaMask approves it. This also upgrades your wallet into a smart account, so the rules can live on chain.

3. A background agent uses the permission to pay for you. You do not sign each time.

4. Every payment is saved to 0G storage, so you always have a clear history of what your agent did.

What it can do today

Right now, agents can pay for services and subscribe to them on a repeating schedule, all in USDC on the Base network.

Your agent can pay a few cents each time it uses a tool, or a small amount on a regular basis. It stops on its own once it hits the daily limit.

Coming next

Token swaps, prediction markets, yield actions, NFT bids, and buying data. All through the same simple card.

You stay in control

Your money never leaves your own account. You can see how much each card has spent, and you can switch any card off in one click. That removes the agent's permission right away.

Built on

The MetaMask Smart Accounts Kit, using Advanced Permissions (ERC-7715) and delegation (ERC-7710), with EIP-7702 account upgrades. It runs on Base, pays in USDC, uses the x402 standard for payments, and stores its history on 0G.

AgiCards is for anyone who wants an AI agent with real spending power, while keeping strict limits and full control of their money.

Proof on chain (Base mainnet)

AgiCards is live and verifiable. Real Advanced Permissions are granted in MetaMask, and the agent redeems them on chain to make capped USDC payments.

During the hackathon, we built the core AgiCards experience.

We created a wallet connection flow with MetaMask on Base, a plain English card creation flow, and a minting flow that grants an agent controlled spending permissions.

We added card dashboards, agent views, spending limits, execution history, and revocation controls.

We also built the backend structure for agent sessions, card storage, permission execution, and audit logs.

The current version supports controlled agent spending for Web3 actions, with the foundation to add more skills such as DeFi trading, prediction markets, and paid API access.

AgiCards is currently bootstrapped and has not raised external funding yet.

We are actively open to strategic funding, partnerships, and ecosystem support as we continue building programmable permission cards for AI agents across Web3 payments, DeFi actions, and prediction markets.
