I built SodaxPay over a weekend using the SODAX SDK. It's a payment link generator. You pick a destination network and token, set an amount, add a memo if you want, and you get a link. Whoever opens that link pays with whatever crypto they hold on whatever network they're on. The recipient gets exactly what they asked for. No signups, fully non-custodial, SodaxPay never touches funds at any point.
Three surfaces make up the app. A creation page where you build the link (desktop-shaped, deliberate). A payment page the payer opens cold (often mobile, one shot at credibility). And a landing page for both audiences.
The build experience is probably more useful than the app itself for anyone here, so here's what it was actually like.
