01Challenge

Cross-border payments lose 3-5% to fees and bad FX — and users can't compare routes because anchors quote opaque prices. Choosing a payment path is a guessing game.

02Strategy

Reframed as a router problem: evaluate multiple Stellar anchors and rails, settle via Rust + Soroban smart contracts, keep state in PostgreSQL/Redis, and surface live prices in a Next.js UI. Dockerized so the whole router spins up in one container.
