guardian-wallet and mpc-agent-wallet
These are direct competitors offering similar threshold MPC wallet infrastructure for AI agents, with the second providing more mature production-grade implementation (2-of-3 signatures, multi-chain support, ERC-4337) compared to the first's simpler guardian model.

Threshold MPC wallet for AI Agents
This project helps operations engineers and developers secure their AI agents' on-chain transactions. It takes your agent's spending requests and applies robust policy checks before co-signing them using a distributed key system. The result is secure, policy-compliant transactions without ever exposing a full private key, giving AI agents controlled autonomy.
About mpc-agent-wallet
Kazopl/mpc-agent-wallet
Production-grade MPC wallet SDK for AI agents. 2-of-3 threshold signatures, multi-chain (EVM + Solana), ERC-4337 smart accounts. Secure key management without single points of failure. TypeScript & Python SDKs with Rust core.
It implements a configurable policy engine enforcing rules like spending limits, address whitelists/blacklists, and time bounds on transactions. Key shares are encrypted at rest using ChaCha20-Poly1305. The SDK integrates with a message relay service for MPC coordination and provides WebAssembly bindings for browser or Node.js environments.
