We built a secure, cross-platform blockchain app using Ionic that gives users a unified Web3 experience across iOS, Android, and the web. From managing multiple wallets to signing transactions and interacting with DeFi protocols, the app is designed for clarity, safety, and advanced users who still appreciate a clean, guided UX.
Under the hood, the app integrates with Web3 providers for Ethereum-compatible chains, handles gas estimation and fee selection, and exposes a DApp browser with deep-link support. Ionic + Capacitor powers a single codebase, while secure key handling, biometric locks, and transaction simulations reduce user risk at every step.
The app lets users move from basic token transfers to exploring DeFi and NFT use-cases, without needing multiple wallets or browser extensions.
Web3 users and projects were hitting friction:
We delivered a branded Ionic Web3 app:
The blockchain app now:
The app combines Ionic’s cross-platform UI with a Web3 integration layer and secure storage so keys never leave the device while still enabling advanced blockchain features.
Sensitive actions (sending, signing) require biometric or PIN confirmation, with clear transaction previews before signing.
Suggested gas presets (slow/normal/fast) plus advanced mode for power users, all based on live network conditions.
Human-readable decoding and risk flags for approvals and contract interactions to reduce “blind signing” risk.
Cached balances and history, graceful offline states, and queued actions that retry when connection is restored.
A CI/CD pipeline (App Store / Play Store builds via Fastlane, environment-based configs) lets the team add new chains, RPC endpoints, or DApp integrations without rewriting the core app.
