AI-Native Self-Custody Wallet for Mobile
Built an iOS and Android self-custody wallet supporting BTC, ETH, LTC, XRP and AVAX with one-tap send, receive and swap, plus a clean activity feed — shipped from clickable AI prototype to App Store in 8 weeks.
Most of our work is under NDA. Per agreement, we can share the work but not the company details — all names and identifying information shown here have been changed.
1 week scope, 2 weeks clickable AI prototype, 5 weeks production build with multi-chain integration.
Bitcoin, Ethereum, Litecoin, Ripple and Avalanche supported natively in one wallet.
Hardware-backed keystore on iOS and Android, biometric unlock, optional cloud-encrypted backup.
Built to MAS Technology Risk Management guidelines for Singapore-licensed operators.
NovaWallet's target users wanted self-custody without the friction of running a power-user wallet. Existing options were either chain-specific, full of advanced settings, or required users to trust an exchange's hot wallet.
We delivered a multi-chain self-custody mobile wallet that supports the five most-held assets in Singapore retail, with one-tap send/receive/swap, ENS-style human-readable recipients, and a clean activity feed — validated through a clickable AI prototype before any chain integration.
Most self-custody wallets feel like they were built for engineers. NovaWallet's users wanted bank-app-level UX with full custody and multi-chain support.
Existing wallets force users to switch between chain-specific apps. NovaWallet had to surface BTC, ETH, LTC, XRP and AVAX in a single token list with one consistent send/receive flow.
Long hex addresses kill UX. Users wanted ENS-style human-readable recipients with clear network selection and confirmation.
Recovery phrases, PIN, biometrics and backup all need to feel safe without scaring non-technical users away.
Singapore's MAS-TRM imposes strict technology risk requirements on wallets operated by licensed entities — auditability, secure storage, and incident response.
Week 1: embedded with NovaWallet's product and crypto-engineering teams to map onboarding, send, receive, swap, and activity flows across all five chains.
Weeks 2–3: built a fully interactive iOS and Android prototype with mocked balances, swap quotes and activity, so the team could click through every flow before any chain integration.
Weeks 4–8: shipped the production wallet for iOS and Android with hardware-backed key storage, multi-chain send/receive, in-app swap, ENS-style recipients, and a clean activity feed.
Most self-custody wallets take 9–18 months to ship to App Store. We delivered a clickable AI prototype in 2 weeks and a production wallet in 8.
Every flow — onboarding, send, receive, swap, activity — was validated in the prototype before we touched a single chain integration.
Design, AI prototyping, on-chain integration and mobile engineering under one roof — no handoff between an app studio and a crypto-integrations vendor.
NovaWallet paid for milestones and live functionality, not hours. Our incentives were tied directly to shipping a wallet that users actually held funds in.
Built a focused onboarding, recovery-phrase backup and PIN/biometric setup flow for a Japanese self-custody wallet — designed to convert first-time holders into confident self-custodians, shipped in 8 weeks.
Built a rider mobile app for an all-electric premium ride-hailing service — live EV map, charge-aware vehicle selection, real-time booking, and trip-completion CO₂ accounting — shipped from clickable AI prototype to App Store in 10 weeks.
