# What is AgentWallex?

> MPC-secured payment gateway for AI agents — send on-chain payments without exposing private keys.

## 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](https://paratro.com)'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

<Steps>
  <Step title="Agent requests a payment">
    Your AI agent calls the AgentWallex SDK or REST API with transaction details (recipient, amount, token).
  </Step>

  <Step title="Policy engine evaluates">
    The request passes through the policy engine, which checks spending limits, address whitelists, token restrictions, velocity controls, and schedule rules.
  </Step>

  <Step title="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.
  </Step>

  <Step title="Broadcast and confirmation">
    The signed transaction is submitted to the blockchain. AgentWallex monitors confirmation and delivers a webhook event when complete.
  </Step>
</Steps>
