MetaMask has released a new self-custodial wallet designed specifically for artificial intelligence agents, letting automated programs trade across decentralized finance protocols while human owners keep final control. The wallet, called Agent Wallet, went live this week and includes mandatory transaction checks, user-defined spending limits, and insurance covering eligible trades up to $10,000.
How Agent Wallet works
Unlike regular crypto wallets where a person signs every transaction, Agent Wallet gives an AI agent a limited permission to initiate trades. The system automatically checks each proposed transaction against rules set by the user — for instance, a maximum trade size, a whitelist of tokens, or frequency caps. If a transaction violates those rules, it gets blocked. The user can also override or approve any trade manually at any time.
MetaMask, built by ConsenSys, has long been a common entry point for retail DeFi users. The new product extends that toolset to autonomous programs, which have become more capable in the past year. Agent Wallet stores private keys on the user's device, not on any server, so the AI agent never gains full custody.
Coverage and safety guardrails
Each eligible transaction through Agent Wallet is covered by MetaMask up to $10,000. The company said the coverage protects against certain types of losses, though it didn't specify which attack scenarios are excluded. Users can set their own limits for both per-transaction amounts and total daily volume.
Mandatory transaction checks run in the background. If an agent tries to send funds to a new address not on the user's list, or if the trade amount exceeds the limit, the system halts execution and alerts the user. That means a compromised or poorly programmed agent can't drain the wallet automatically.
Targeting the growing AI agent market
Agent Wallet aims at what MetaMask estimates is a $236 billion market for AI agent services. The figure includes both the agents themselves — software that performs tasks like trading, data analysis, or content management — and the infrastructure supporting them. As more developers experiment with autonomous crypto traders, the wallet provides a way to contain risk.
MetaMask rival wallets have offered similar features, but Agent Wallet is the first from a major non-custodial provider to bundle coverage and rule-based limits as standard. The product is available now as a separate download. Users need to install it, connect an existing MetaMask account, and then set up an agent key pair.
The company hasn't said when it might expand the coverage beyond $10,000 or add support for multi-agent setups. For now, the wallet works with any EVM-compatible chain that MetaMask supports — including Ethereum, Polygon, Arbitrum, and Optimism.
