MetaMask launches its agent wallet, Glamsterdam Testnet goes public, a lattice-crypto attack draws doubt, NEAR Intents unifies liquidity

Welcome to our weekly digest, where we unpack the latest in account and chain abstraction and the broader infrastructure shaping Ethereum. This week: MetaMask launches a self-custodial wallet built for AI agents; Ethereum core devs send Glamsterdam to a public testnet while Frame Transactions pick up client support for Hegota; a new quantum attack on lattice-based cryptography draws quick skepticism; and NEAR Intents grows into a single cross-chain liquidity layer. MetaMask Launches Its Agent Wallet Glamsterdam Testnet Goes Public as Hegota Advances A Lattice-Crypto Attack Draws Doubt NEAR Intents Becomes a Unified Liquidity Layer Please fasten your belts! MetaMask Launches Its Agent Wallet MetaMask launched its Agent Wallet , a self-custodial wallet built for AI agents to execute onchain actions inside rules the user sets. It lets traders and builders connect an agent framework, then define spend limits, allowlisted protocols, and a risk profile before the agent acts. The pitch is that safety is the product. Agent Wallet is not blind delegation, so supported transactions pass through MetaMask’s security pipeline, including transaction simulation, Blockaid-powered threat scanning, and MEV protection, and anything outside policy pauses for two-factor approval. Users pick between two modes. Guard Mode, the default, enforces daily spend limits, allowlists, and human approval for out-of-policy actions, while opt-in Beast Mode reduces approval interruptions but still runs security checks and still stops flagged transactions. On capabilities, agents can connect frameworks like Claude Code, Codex, and Cursor and execute across HyperLiquid and EVM chains such as Robinhood and Monad. They can run ERC-7821 batch swaps, and they never need a chain’s native gas token, since MetaMask settles the fee in the token being moved. This is account abstraction in a very practical form. Spend limits, allowlists, gasless execution, and batching are exactly the programmable account feature
