The stablecoin payment stack on /base is forming fast. /x402 nails micropayments — agent hits API, pays $0.10 USDC inline, gets response. No account, no API key. Brilliant. But what about the other side? A client pays you $10K in USDC for a project. Or $99/mo for a SaaS subscription. Nobody's watching the chain for you. That's what we built PayWatcher for. → You create a payment intent → We watch Base for the exact transfer → Webhook fires when confirmed $0.05 flat. Non-custodial. No checkout. /x402 for micropayments. PayWatcher for everything else. paywatcher.dev #BuildOnBase #USDC #x402 #Web3

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%. Live now → paywatcher.dev Looking for devs building on Base who accept USDC. Free tier available. #BuildOnBase #Base #USDC #Stablecoins #Web3 #DevTools #Payments
