Description

Dompet Ku Mobile App is a cross-platform mobile wallet that allows users to manage assets across multiple blockchain networks including Ethereum, Solana, and Bitcoin. The app provides a full-featured wallet experience with asset tracking, transaction history, wallet creation/import, and a built-in dApp browser for interacting with decentralized applications.

The app is designed for security, performance, and multi-chain compatibility, using advanced encryption and local storage to protect sensitive data.

My Role

As the lead mobile developer, I was responsible for:

1. Building the app with Flutter and managing state with GetX.
2. Integrating multi-chain blockchain libraries:
3. Web3 Dart - Ethereum/EVM networks
4. Solana Dart library - Solana network
5. Bitcoin_base & blockchain_utils - Bitcoin network
6. Implementing wallet management using Reown WalletKit.
7. Generating and securing seed phrases with BIP32.
8. Implementing local encrypted storage with GetStorage and AES CBC encryption.
9. Connecting to the Gin backend and PostgreSQL database.
10. Developing features like multi-chain asset tracking, sending transactions, wallet creation/import, and dApp browser.
