🌞 Solana Wallet Chrome Extension (bwalletteSolana)

📝 Description

A Chrome browser extension for interacting with the Solana blockchain. It allows users to create, import (partially implemented), and manage Solana wallets directly within their browser popup. This project demonstrates key Solana functionalities like keypair generation (random and deterministic), transaction signing for transfers, viewing account activity, and interacting with the Devnet.

🚀 Setup and Installation

1. Install dependencies:

   npm install
   # or
   yarn install

2. Environment Variables:

   • The application uses process.env.NEXT_PUBLIC_SOLANA_RPC_HOST to connect to the Solana network. If not set, it defaults to the public Solana Devnet RPC (https://api.devnet.solana.com).
   • For better performance and reliability, consider setting this variable to a dedicated RPC endpoint (e.g., from Helius, QuickNode, Alchemy, or your own node). Create a .env.local file in the root directory:

   NEXT_PUBLIC_SOLANA_RPC_HOST=https://api.devnet.solana.com
   # Or replace with your dedicated RPC URL
   

3. Build the extension:

   • You need to build the Next.js application and export it as static files suitable for a Chrome extension. Check your package.json for the specific scripts, but they are typically:

   yarn build

4. Load the extension in Chrome:

   • Open Chrome and navigate to chrome://extensions/
   • Enable "Developer mode" (usually a toggle in the top right)
   • Click "Load unpacked"
   • Select the out directory generated in the previous step
   • The extension icon should appear in your browser toolbar. Ensure your manifest.json is configured correctly to use popup.html (or the equivalent exported file) for the browser action

Development Notes

• The application is configured to interact with the Solana Devnet by default
• Funding for new wallets is provided via an integrated call to a Devnet faucet function (fundWallet). Faucet requests may be rate-limited by the RPC provider
• Ensure you have a stable RPC connection for reliable transaction fetching and submission. Public RPC endpoints (like the default api.devnet.solana.com) have strict rate limits, which can cause errors during heavy use (like fetching many transaction details). Consider using a dedicated RPC provider for development
