NovaWallet - Multi-Chain Self-Custody Mobile Wallet
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.
Impact
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.
The Problem
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.
Our Solution
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.
The Challenge: Self-Custody Without the Power-User Tax
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.
Multi-Chain Without Mode Switching
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.
Recipient Friction
Long hex addresses kill UX. Users wanted ENS-style human-readable recipients with clear network selection and confirmation.
Self-Custody UX
Recovery phrases, PIN, biometrics and backup all need to feel safe without scaring non-technical users away.
MAS-TRM Compliance
Singapore's MAS-TRM imposes strict technology risk requirements on wallets operated by licensed entities - auditability, secure storage, and incident response.
Our Approach: 3 Phases in 8 Weeks
Discovery & Scope
Week 1: embedded with NovaWallet's product and crypto-engineering teams to map onboarding, send, receive, swap, and activity flows across all five chains.
AI-Driven Clickable Prototype
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.
Production Build & Launch
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.
Why It Works: Outcome-Based Differentiation
Speed to Value
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.
AI-First Prototyping
Every flow - onboarding, send, receive, swap, activity - was validated in the prototype before we touched a single chain integration.
Single Accountable Team
Design, AI prototyping, on-chain integration and mobile engineering under one roof - no handoff between an app studio and a crypto-integrations vendor.
Outcome-Based Engagement
NovaWallet paid for milestones and live functionality, not hours. Our incentives were tied directly to shipping a wallet that users actually held funds in.
