I'm thrilled to announce my project submission for the MIT Bitcoin Hackathon 2023: Bitchat Wallet! Bitchat Wallet is a secure and user-friendly Bitcoin on-chain wallet that enables communication and transactions between users based on BDK and Nostr.

As a Bitcoin and Nostr enthusiast, I saw a need for a secure and easy-to-use platform for transferring bitcoins between users, and Bitchat Wallet is my solution to that problem. With features like requesting bitcoins from other users, sending and receiving bitcoins securely, and E2EE communication, Bitchat Wallet provides a seamless experience for users.

I developed Bitchat Wallet using Flutter framework for the frontend, Bitcoin Development Kit, and Nostr Tools Dart package, specifically Nip-06, Nip-19, and Nip-04.

While Bitchat Wallet is currently available on the Bitcoin testnet, I have plans for future development, including support for coinjoins, integration with other wallets and platforms, and support for mainnet transactions.

I'm excited about the potential of Bitchat Wallet and how it can benefit the Bitcoin community. If you're interested in learning more about Bitchat Wallet or have any feedback to share, please don't hesitate to reach out. Thank you for your support!
