MetaMask has launched Agent Wallet, a self-custodial wallet that allows ai agents to execute on-chain crypto transactions within rules set by users. The product became publicly available on August 6, 2026, following an early-access phase that began in June. MetaMask announced that Agent Wallet is now live for everyone, marking a significant expansion of AI-powered tools in decentralized finance (DeFi). Developed by Consensys, MetaMask Agent Wallet is designed for traders and developers who want AI agents to monitor markets, identify opportunities and execute transactions without requiring manual approval for every trade. 

However, the wallet does not give an AI system unrestricted control over a user’s funds. Instead, users establish spending limits, approved protocols and risk preferences before the agent begins operating. The launch comes as crypto activity increasingly moves toward automated and algorithmic execution. AI agents can process market data continuously, compare liquidity across platforms and respond to changing conditions faster than a human trader. MetaMask is positioning Agent Wallet as infrastructure for this emerging “agentic” economy, while attempting to preserve the self-custody principles associated with cryptocurrency wallets.

How Agent Wallet works

Users can connect Agent Wallet to supported AI development frameworks, including Claude Code, Codex, Cursor, OpenClaw, Hermes and OpenCode. The wallet is built around a command-line interface, allowing agents to interact with on-chain applications through structured instructions rather than a conventional point-and-click wallet interface.

Agent Wallet supports a range of DeFi activities, including token swaps, perpetual futures, prediction markets, staking and liquidity provision. It operates across Hyperliquid and a growing list of Ethereum Virtual Machine-compatible networks, including Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Linea, Sei and Monad. MetaMask has also highlighted integrations with platforms such as Polymarket, Aave, CoW Swap and LI.FI. 

Users can choose between two operating modes. Guard Mode is the default setting and applies daily spending limits, allowlisted protocols and two-factor authentication for transactions that fall outside the user’s policy. Beast Mode is an opt-in setting for experienced users who want fewer interruptions and broader flexibility. Even in Beast Mode, transactions identified as malicious are blocked or sent for additional approval.

Security remains central

MetaMask says every supported EVM transaction passes through a mandatory security pipeline before execution. This includes transaction simulation, threat scanning powered by Blockaid and MEV-protected transaction processing. The system is designed to show potential balance changes, approvals and fee routes before a transaction is completed. Transactions that are flagged as suspicious, exceed spending limits or involve non-approved protocols can be paused for human review. Users receive approval requests through the MetaMask mobile application or an email link, and the agent cannot proceed until the request is accepted. Eligible transactions that pass MetaMask’s security checks may also qualify for Transaction Protection of up to $10,000 per month, subject to the company’s terms and conditions. The coverage is not a guarantee against all trading losses, and users remain responsible for understanding the risks of automated crypto trading.

Gas abstraction and user control

Another notable feature is gas abstraction. Agents can transfer or swap assets without first holding a blockchain’s native token to pay transaction fees, as MetaMask settles the network fee using the asset being moved. This could simplify automated trading across multiple networks, where managing separate gas balances has traditionally added friction. Despite the automation, Agent Wallet remains self-custodial. Users retain control of their keys and can export their recovery phrase. That distinction may be important for traders who want the speed of AI execution without placing funds under the custody of an exchange or third-party service.
