MicroLend XRPL is a lightweight peer-to-peer microloan platform built to demonstrate how permissionless ledgers can power fairer, transparent credit for underserved borrowers. The idea was inspired by field research on microfinance and by the XRPL ecosystem’s low-cost settlement primitive — I wanted a small, practical demo that shows how on‑chain escrows and tokenized stablecoins can enable trust-minimized lending flows.
- What inspired me: real-world microcredit workflows and the XRPL toolkit — I wanted to combine real financial UX (loan creation, milestones, repayments) with robust on‑chain settlement without heavy infrastructure.
- What I learned: practical integration patterns for XRPL (escrows, multisig-like flows), designing defensive APIs for financial actions, and the trade-offs between UX simplicity and key management/security. I also improved my end-to-end test and deployment experience (adding smoke/unit tests and safer env management).
- How I built it: a Node.js + Express backend that orchestrates XRPL transactions and stores app state, and a React frontend (Tailwind CSS) that guides users through wallet creation, loan listings, and milestone approvals. I added focused tests (backend smoke tests, frontend unit tests) and created small service modules (escrow, stable token service, reputation) to keep responsibilities clear.
- Challenges faced: safely handling seeds (one-time reveal on registration), reproducing intermittent runtime issues (stale process vs. old code references), and cleaning a repo that had tracked large vendored files (node_modules) and sensitive .env contents. Operationally, designing UX that is secure yet approachable for users unfamiliar with private key concepts was a recurring tradeoff.
