Wallet, transfers, and secure authentication at scale
The Challenge:
- Users required bank-grade security without adding friction: biometrics, step-up auth, and risk scoring.
- Payment failures and network retries needed to be invisible to the user, with clear recovery paths.
- Transaction analytics had to be understandable to non-technical customers while meeting fraud controls.
Our Approach:
- End-to-end encryption, device binding, and threat-aware login flows; PCI scope reduction via tokenization path.
- Idempotent money movement APIs, optimistic UI with strong reconciliation, and in-app support hooks.
- KPIs inside the app: spend, savings, and activity feed with education modules for first-time fintech users.
The Challenge:
Security & product:Threat model, auth story, and regulatory-ready UX copy review.
UX & design:Clarity for balances, fees, and limits; motion kept minimal for trust.
Engineering:App shell, real-time ledgers, and observability (APM + crashlytics).
Release & test:Staged rollouts, device matrix, and incident runbooks for money flows.
Key Features Delivered:
- Biometric unlock, step-up 3DS, and in-app device management for high-risk events.
- Real-time P2P and top-ups with clear fees, receipts, and shareable payment proofs.
- Fraud and velocity signals surfaced as friendly prompts instead of hard errors.
- Business reporting: exports, month summaries, and CSV for accountants.
