PayWatcher is Live
Source: Dev.to

Introduction
We just shipped PayWatcher — payment verification for USDC on Base.
Problem
Verify a $10k stablecoin payment and you either pay $100 to a processor or build your own blockchain listener from scratch.
Solution
PayWatcher is the missing middle: create a payment intent, we watch Base for the transfer, and a webhook fires when confirmed.
- $0.05 flat fee
- Non‑custodial
- You keep 100%
