MPC-Secured Payment Gateway for AI Agents
Give your AI agents the ability to transact on-chain — securely. MPC wallet protection, policy-gated spending, x402 micropayments, and multi-chain support out of the box.
AI Agents Need to Spend Money.
But Today's Infrastructure Isn't Ready.
Four critical gaps block agents from becoming autonomous economic actors.
Agents Can't Safely Hold Private Keys
A single prompt injection can extract keys from agent memory, draining all funds instantly.
prompt injection → key extracted → 47,832 USDC drained → NO RECOVERY
No Standardized Agent Payment Protocol
Every developer builds their own payment integration from scratch. No shared standard exists.
100 agent teams → 100 different payment implementations → 100× duplicated effort
Agent Platforms Lack Payment Capability
Without built-in payment, agents are limited to free tasks only. Monetization is impossible.
agents can browse, chat, code → but can't buy API access, pay for services, or tip
Payment Infrastructure Is Too Heavy
Teams spend months building payment plumbing instead of focusing on their core agent logic.
3 months building payments + key management → 1 day writing actual business logic
One Gateway.
Everything Agents Need to Pay.
AgentWallex combines MPC security, x402 micropayments, and native agent integration into a single payment gateway.
MPC Signing Service
Paratro 2-of-3 threshold signing. Agents never touch private keys. Key shards distributed across independent nodes.
x402 Facilitator
Off-chain authorization in 30-80ms. Batch settlement on-chain. Agents auto-pay for API calls on HTTP 402.
Payment Agent (MCP Tool)
Official MCP-compatible payment tool. Agent platforms install it from marketplace — zero integration code needed.
Two Payment Scenarios
Direct on-chain payments for standard transactions. x402 micropayments for API-to-API commerce.
Agent pays a merchant or service provider. Each transaction is signed and broadcast on-chain.

Policy engine validates limits & whitelist

Large Payments
Agent calls a paid API. On HTTP 402, payment is authorized off-chain and settled in batches.

Two Ways to Integrate.
Pick What Fits Your Stack.
Use the SDK for full control, or install the Payment Agent as an MCP tool for zero-code integration.
npm install and 3 lines of code. Full programmatic control over wallets, payments, and policies.
// 3 lines to pay
import { AgentWallex } from "@agentwallex/sdk"
const aw = new AgentWallex({ apiKey })
await aw.payments.send({ to, amount, token: "USDC" })
Install from the marketplace. Agent self-provisions its wallet and starts transacting — no code required.
Compatible with leading agent platforms
Four Layers of Protection
From identity verification to human approval — every transaction passes through multiple security checkpoints.
Identity & Auth
API Key + Session Token authentication. Scoped permissions per agent. Token rotation and expiry.
Policy Engine
Per-agent spending limits, address whitelists, velocity controls, time locks, and circuit breakers.
Paratro MPC
2-of-3 threshold signing. Key shards on independent nodes. Keys never reconstructed. Instant freeze.
Human-in-the-Loop
High-value transactions route to human approval. Configurable thresholds. Instant session freeze.
Two-Layer Policy Architecture
Business policies and infrastructure safety nets work independently — even if the business layer is compromised, the infrastructure layer still protects funds.
Business Layer
Custom spending limits, whitelists, velocity rules set by the developer.
Infrastructure Safety Net
Paratro-enforced hard caps, anomaly detection, and emergency freeze.
TypeScript-First Developer Experience
Integrate in minutes. Type-safe SDK with full IntelliSense support.
import { AgentWallex } from "@agentwallex/sdk";
const aw = new AgentWallex({
apiKey: "aw_live_...",
environment: "production"
});
const agent = await aw.agents.create({
name: "research-bot",
chain: "polygon",
policies: {
dailyLimit: "500",
allowedTokens: ["USDC"],
requireHumanApproval: true,
humanApprovalThreshold: "100"
}
});
console.log(agent.wallet.address);
// 0x7f3a...9c2d{
"id": "agent_8xKm2nP",
"name": "research-bot",
"wallet": {
"address": "0x7f3a...9c2d",
"chain": "polygon"
},
