MetaMask has released Agent Wallet, a self-custodial wallet designed to let artificial intelligence agents execute onchain trades automatically while staying within user-defined security limits. The product, announced by the wallet provider, aims to bridge the gap between autonomous AI tools and the strict control that crypto users expect over their funds.
How Agent Wallet works
Agent Wallet is a separate wallet within the MetaMask ecosystem, not a replacement for the main wallet. Users can set specific rules—such as maximum trade size, allowed tokens, or whitelisted smart contracts—that the AI agent must follow. The agent then initiates trades on decentralized exchanges or other protocols, but only within those boundaries. The wallet remains self-custodial, meaning the user holds the private keys and the agent cannot move funds outside the preset rules.
The launch comes as more crypto users experiment with automated trading bots and AI-driven strategies. MetaMask's approach puts the guardrails in place before the agent can act, rather than relying on post-trade monitoring.
Why self-custody matters for AI agents
Self-custodial wallets give users full ownership of their assets, but they also require manual signing for every transaction. That friction makes it hard to automate trades without handing over keys to a third party. Agent Wallet solves this by letting users pre-approve a set of actions the AI can take, while keeping ultimate control in their own hands. The company says this design is meant to prevent the agent from ever accessing the user's entire balance or signing arbitrary transactions.
The move reflects a broader push in crypto to make autonomous agents more practical without sacrificing security. Other projects have tried similar ideas, but MetaMask's large existing user base could give Agent Wallet a head start.
MetaMask has not disclosed how many users have signed up since the launch, nor has it announced a specific timeline for additional features. The wallet is available now through the MetaMask extension and mobile app. Developers can also integrate Agent Wallet into their own applications using the provided API.
The company says it plans to add more rule types and support for additional blockchains in future updates. For now, the wallet works with Ethereum and several EVM-compatible networks.
