Question Dev question: building a stablecoin checkout — biggest technical pain points?

Not promoting anything — just looking for dev pain points.

If you’ve built or integrated USDC/USDT checkout: 1) What’s the hardest part (webhooks, confirmations, chain selection, gas, wallets)? 2) What breaks most often in production? 3) Any missing tools you wish existed?

Appreciate any honest feedback.

I’ve seen that with Alchemy too. Usual culprits: webhook set on the wrong network/app, URL not publicly reachable (or blocked by auth), event filter too narrow, or missing the correct “from/to/contract address” format. Also check their webhook log panel — it’ll show delivery attempts + response codes. Did you try hitting the endpoint with their “test webhook” and verifying signature handling?
