Wallets & Tooling provides the key management and transaction infrastructure that AI agents need to hold, send, and receive digital assets. Unlike human wallets, agent wallets require programmable spending policies, delegated access, and autonomous signing capabilities.

Turnkey leads with hardware-backed infrastructure offering sub-100ms signing. Coinbase, MetaMask, and Fireblocks bring enterprise-grade MPC and smart account solutions.

Privy provides server-side wallet provisioning with configurable guardrails. The category also includes security tooling: Varlock for AI-safe environment variable management and mlld for secure LLM scripting that prevents private key leakage.

Rhinestone's ERC-7579 modular smart accounts enable fine-grained permission scoping — giving trading bots access to swap functions while blocking withdrawal capabilities.
