Sniff - Web-based Crypto Wallet

Sniff is a web-based cryptocurrency wallet that provides MetaMask-like functionality for the Solana blockchain, enabling users to manage their SOL and SPL tokens directly in the browser.

I developed the complete wallet interface with real-time balance updates, secure transaction signing, and support for multiple SPL tokens with automatic token detection.

The wallet features robust security measures including encrypted private key storage, secure transaction broadcasting, and comprehensive error handling for failed transactions.

I implemented advanced features like transaction history, token management, and integration with Solana's RPC endpoints for reliable blockchain communication.

This project showcases my deep understanding of blockchain technology, cryptography, and building secure Web3 applications.
