Built a domain registry and marketplace on the XRP Ledger. $3M+ revenue, 20K+ MAU
A naming layer for the XRP Ledger: search, register, manage, resolve, and trade human-readable names, plus a wallet, SDK, and resolver so apps can integrate in minutes.
Built the wallet, main app (registrar/manager/marketplace), landing site, and the SDK + resolver from scratch. Owned architecture, infrastructure, and operations.

Solution
End-to-end flow: search → register → manage → transfer/marketplace. XNS Wallet: lightweight, non-custodial wallet optimized for registration and transfers. SDK + Resolver: TypeScript kit and HTTP endpoints for forward/reverse lookups.
Commit-reveal flows and premium windows to prevent front-running. Redis/edge caching, write queues, and graceful degradation during traffic spikes. Classic/X-address and destination tag handling with idempotent retries.




Outcome
20K+ MAU; platform generated $3M+ in revenue. Thousands of registrations with active secondary trading. Third-party adoption via the SDK + resolver; high uptime despite targeted DDoS attacks.
