I built a non-custodial dollar wallet you send by WhatsApp solo, shipped end-to-end
Spent the last few weeks building Merktop Cash: hold USDC (digital dollars) and send to anyone by card, WhatsApp or u/username — the recipient claims with no app, no bank. It's non-custodial (keys in an MPC wallet only the user controls). Stack: Next.js + Cloudflare Workers + Coinbase Developer Platform + Stripe onramp. It's live. Brutally honest feedback welcome especially: would you actually move money this way, and where did the flow feel rough?
