Challenge

Complex infrastructure, simple surface

The product team needed a wallet that handled fiat top-ups, crypto transfers, and merchant payments without exposing users to blockchain mechanics. The existing prototype could not reconcile across multiple rails, and fraud controls were missing entirely.

No multi-rail reconciliation in the legacy prototype
Key management and fraud velocity rules were not defined
App Store guidelines demanded clear disclosures for crypto features

Solution

Hardened wallet with abstracted payment complexity

We built a React Native application backed by secure services that route payments across custodial and non-custodial paths. Users see balances update in real time without understanding which rail moved the money.

Unified ledger engine with per-rail settlement tracking
Biometric authentication, device binding, and velocity-based fraud limits
QR code and deep-link merchant payment flows
Compliance-ready transaction export and audit history

Results

Users transferred money without thinking about crypto

Launch metrics beat targets across the board. Support volume stayed well below industry benchmarks because users could complete transfers without friction.
