Why AgentWallex?

​

The Problem

AI agents are increasingly autonomous — they browse the web, call APIs, and make decisions. But when an agent needs to pay for something, the options are limited and dangerous:

• Giving agents private keys means a single prompt injection or bug can drain the wallet entirely.
• Human-in-the-loop for every payment defeats the purpose of autonomous agents.
• Traditional wallet infrastructure was designed for humans clicking buttons, not machines making thousands of decisions per hour.

​

What AgentWallex Does Differently

​

No Private Key Exposure

AgentWallex uses 2-of-3 threshold MPC signing via Paratro. The full private key is never reconstructed — not in memory, not on disk, not anywhere. Even if your agent or API key is compromised, the attacker cannot sign transactions alone.

​

Policy Engine as a Safety Net

Every transaction passes through a configurable policy engine before signing. Set per-agent limits on:

• Transaction amount — cap individual payments
• Daily and monthly totals — rolling spending limits
• Allowed addresses — whitelist trusted recipients
• Token restrictions — limit to stablecoins only
• Velocity controls — prevent runaway transaction loops
• Time-based rules — restrict to business hours
• Human approval — route high-value transactions to human review

​

Infrastructure Safety Net

Even if your business-layer policies are misconfigured, Paratro enforces hard limits at the MPC signing level that cannot be overridden by API calls:

​

x402 Native Support

AgentWallex natively supports the x402 machine-to-machine payment protocol. Your agents can automatically negotiate and pay for API access using HTTP 402 headers — no human intervention needed.
