Upchain Wallet: A Fully Open-Source Ethereum Wallet with Powerful Features

If you've been searching for a reliable, fully open-source Ethereum wallet, your hunt ends here. Upchain Wallet is now completely open-source—yes, all its code is available for scrutiny, modification, and implementation. No more settling for partially open-sourced wallets or worrying about private key security.

Why Open-Source Matters in Blockchain

Blockchain thrives on transparency. Closed-source projects struggle to build trust, which is why the community champions open-source principles. By open-sourcing Upchain Wallet, we aim to:

• Lower development barriers for startups and developers.
• Foster innovation by enabling real-world use cases.
• Enhance security through collective auditing (partnered with Zero-Time Tech for professional audits).

Key Features

Upchain Wallet supports:

1. Multi-Network Compatibility:

   • Ethereum Mainnet
   • Testnets (Infura Kovan, Ropsten)
   • Local test networks (Ganache/Geth)

2. Developer-Friendly Tools:

   • Free test ETH for debugging.
   • ERC20 token deployment via included ERC20_Contract templates.

3. User-Focused Security:

   • Offline private key storage (never uploaded to servers).

4. Real-Time Data:

   • Transaction history (requires self-hosted Trust-Ray API).
   • Cryptocurrency prices (via CoinMarketCap; may require future API key).
