Core Features of UpChain Wallet

The strength of UpChain lies in its comprehensive feature set that combines usability with advanced blockchain functionality.

Multi-Method Wallet Creation & Recovery

You can create a new Ethereum wallet using one of three standard methods:

All credentials are stored locally on your device—never transmitted or backed up on remote servers. This ensures maximum security and aligns with best practices in self-custody.

Seamless Multi-Account Management

Switch between multiple Ethereum accounts effortlessly. Ideal for users managing personal funds, testnet experiments, or separate investment strategies—all from a single app interface.

Full ERC20 Token Support

Track and transfer popular ERC20 tokens such as USDT, DAI, UNI, and more. The wallet displays real-time balances and integrates live price data in both USD and CNY, helping you stay informed about your portfolio’s value.

Real-Time Cryptocurrency Pricing

Stay updated with accurate, up-to-the-minute market rates. The app fetches current ETH and token prices automatically, converting values into fiat currencies so you always know your holdings’ worth.

Transaction History & QR Code Scanner

Review all incoming and outgoing transactions directly within the app. Each entry includes timestamp, amount, transaction hash, and status. For quick transfers, the built-in QR code scanner supports standard Ethereum formats—including compatibility with imToken—for seamless peer-to-peer payments.

Built-In DApp Browser

Interact with the decentralized web through the integrated DApp browser. Access DeFi platforms, NFT marketplaces, blockchain games, and other Web3 services without leaving the wallet environment. This feature bridges the gap between asset management and active participation in the Ethereum ecosystem.

Test Network Support

Developers and testers will appreciate native support for major Ethereum testnets:

This makes UpChain an excellent tool for building, testing, and debugging smart contracts and DApps before deploying to mainnet.

Future Enhancements in Development

While already feature-rich, the roadmap includes improvements such as:

These upcoming updates aim to transform UpChain into a true multi-chain wallet capable of serving a broader range of crypto users.

How to Run or Contribute to UpChain Wallet

Developers interested in auditing, contributing, or self-hosting the wallet can do so easily thanks to its open-source nature.

The project is built using Android Studio, making it accessible to most Android developers. To configure the project locally:

  1. Create a local.properties file in the root directory.
  2. Add the following configurations:
sdk.dir= /path/to/your/android/sdk
gpr.user=your_github_username
gpr.key=your_github_token
infura.key=your_infura_project_id
Note: The infura.key is required to connect to Ethereum nodes via Infura. You can obtain a free API key by registering on their website.

For guidance on setting up GitHub Packages (gpr.user and gpr.key), refer to Trust Wallet’s integration documentation for Android development.
