Overview
AgentWallex is an MPC-secured wallet infrastructure and payment gateway purpose-built for AI agents. It enables autonomous agents to transact on-chain — sending payments, paying for APIs, and managing funds — without ever exposing private keys. Built on Paratro’s 2-of-3 threshold MPC protocol, AgentWallex ensures that no single party ever holds a complete private key. A configurable policy engine evaluates every transaction before it reaches the signing layer, giving developers fine-grained control over what their agents can do.How It Works
Agent requests a payment
Your AI agent calls the AgentWallex SDK or REST API with transaction details (recipient, amount, token).
Policy engine evaluates
The request passes through the policy engine, which checks spending limits, address whitelists, token restrictions, velocity controls, and schedule rules.
MPC signing
If the policy check passes, the transaction is signed using 2-of-3 threshold MPC. The full private key is never reconstructed in memory.
