Custom Blockchain Development with Cross-Chain Bridges and Web Btc Wallets

We are seeking an experienced blockchain developer or team to design and implement a custom blockchain solution. The primary purpose of this new blockchain will be to securely store Bitcoin (BTC) in a simplified and fundamental manner. The project requires the development of two essential cross-chain bridges to facilitate asset movement:

1.  Bitcoin Network Bridge: A bridge connecting our custom blockchain with the native Bitcoin network. This bridge will enable the locking of real BTC on the Bitcoin network and the subsequent minting of an equivalent representation on our custom blockchain.
2.  Ethereum Network Bridge: A second bridge to link our custom blockchain with the Ethereum network. This will allow for the locking of assets on our chain and minting on Ethereum, or vice versa, focusing on BTC representation.

Additionally, the project includes the creation of two simple web-based BTC wallets with core functionalities (send and receive):

1.  Custom Blockchain BTC Wallet: A web wallet designed to interact with our newly developed blockchain, allowing users to manage their BTC stored on our chain.
2.  Non-Custodial Bitcoin Network Wallet: A web-based, non-custodial wallet that directly interacts with the Bitcoin network for storing and managing actual BTC.

The goal is to build this project in the most straightforward and basic way possible, focusing on core functionality and security. Further details regarding specific requirements and minor functionalities will be shared upon agreement.
