Buyer-facing guides for screening wallets before payouts or paid x402 work, plus the monitoring and forensics layers that matter after that first decision.
The vision is agentic commerce. The product you can buy today is simpler: screen wallets, investigate risk, and add alerts before payouts or paid x402 route execution.
x402 verifies payment. It does not decide whether a wallet looks trustworthy enough to spend your compute or receive a payout. Here is the simplest Hono middleware pattern for that check.
Before your app sends a payout to an external wallet, check the counterparty and decide whether to allow, review, or stop it. This is the same screening pattern at a different workflow boundary.
The first production policy should be conservative, boring, and easy to explain. Start with one simple rule set you can defend, then tune it with real traffic.
Most first lookups on Base are still thin. The right move is not to pretend that problem does not exist. It is to separate thin data from bad behavior and choose safer defaults.
We analyzed our own payment wallet and discovered real x402 transfers, address poisoning attacks, and a fake token scam. Here is what on-chain forensics looks like in practice.
Cloudflare now supports x402 in Agents SDK and MCP flows. This guide shows the extra step paid routes still need: screening the wallet after payment verification and before work starts.
If your assistant or agent can already call MCP tools, you can make wallet checks part of the tool loop. This is the fastest way to teach an agent when to trust, review, or avoid a wallet.
Screening is the wedge. Monitoring is the operating layer around it. This guide shows how to create watched-wallet subscriptions, alert on score or anomaly changes, and wire the results into your ops flow.
How we use on-chain behavioral forensics to separate real AI agents from manufactured identities — tight cluster rings, symmetric round-trips, coordinated creation, puppet funding, and bot-like timing.
