The situation

Users abandoned transfers because the old app required 14 fields, manual SWIFT codes, and showed stale exchange rates.

What we built

A contact-based send flow that auto-fills routing details from a phone number or email.
Live exchange rate preview with a firm 60-second lock, so users know exactly what the recipient gets.
Face ID and fingerprint unlock with device-bound encryption — no passwords to forget.
