Published our full builder story on Paragraph.
What we built: x402-native USDC verification on Base. Why the existing options ($100 per $10k transfer) make no sense for stablecoin payments. What's next: MCP server.

Most payment processors charge a % of every transaction. For stablecoin payments, that makes no sense.
You don't need a middleman. You just need to know the payment arrived.

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

Looking for devs building on Base who accept USDC. Free tier available.
