How We Built a Browser-Based Monero Wallet With Zero KYC

Most Monero wallets require you to either download an app, sync a full node, or hand over your personal data. We wanted to build something different — a Monero wallet that works the moment you open it in your browser. No installs, no KYC, no email. Just a seed phrase, a password, and a working XMR address in under 30 seconds. Here's how we built WebMonero and the technical decisions behind it. The Problem If you want to use Monero today, your options look like this: Monero GUI — full node sync (100+ GB, several hours), desktop only Feather Wallet — lightweight but still desktop only Cake Wallet — great mobile app, but you need to install it MyMonero — has a web version, but the interface is from 2017 There's a gap: no modern, fast, browser-based wallet for Monero that respects user privacy. We decided to fill it. Architecture Overview The stack is intentionally simple. Fewer moving parts = fewer things that break. Backend: Python + Flask SQLite with WAL mode (fast reads, atomic writes)
