AI Agent Wallet

In Brief
An AI agent wallet is a crypto wallet operated by an autonomous AI agent, letting software hold funds and pay for services on its owner's behalf — ideally within strict, programmable limits the owner sets in advance.
What Is an AI Agent Wallet?
An AI agent wallet is a crypto wallet operated by an autonomous AI agent rather than directly by a human. It lets software hold funds and make payments on its owner's behalf — paying for API calls, data, or services — ideally within strict, programmable limits the owner defines in advance.
Crypto suits agents because it's machine-native: an agent can hold keys and settle payments without a bank account, card, or human in the loop. The hard problem isn't the payment — it's authority: giving an agent enough spending power to be useful without giving it enough to be dangerous.
How Agentic Payments Work
The owner provisions the agent with a wallet — its own key, a session key, or a sub-account of a smart account.
Policy rules are set in code: spending caps, allowed recipients or merchants, expiry dates.
The agent transacts autonomously within those bounds — paying per API call, per task, or per resource.
The owner monitors activity and can revoke the agent's authority at any time.
Risks and Design Principles
A key is total power: an agent holding an unrestricted key can lose everything to a bug or a prompt injection.
Least privilege wins: small budgets, short-lived keys, and tight allowlists limit the blast radius.
Agents can be manipulated: malicious content an agent reads can try to redirect its payments.
Revocation must be real: if you can't cut the agent off instantly, the limits are theater.
AI Agent Wallets and Trust Wallet
Trust Wallet is built for humans holding their own keys: self-custody, where nothing moves without your signature. As agentic payments mature, the same principle carries over — an agent should get delegated, limited authority, and never your secret phrase.
