Bitcoin-Based Crypto Platform Development

I have a new crypto initiative that must run natively on the Bitcoin blockchain. While the exact product layer—be it a trading interface, a secure wallet, or an analytics dashboard—will be shaped together, the underlying requirement is clear: every function has to interact directly with the Bitcoin network, not a generic multi-chain wrapper.

Here is what I need from you: first, a concise technical proposal that outlines the architecture, security approach, recommended stack, and phased timeline. Once we agree on the blueprint, you will take the lead in spinning up a full Bitcoin node (testnet first), exposing clean JSON-RPC endpoints, and building the core modules that handle address generation, transaction creation, signing, and broadcasting. The front-end framework is flexible—React, Vue, or a lightweight alternative—as long as it speaks seamlessly to the back-end APIs.

Deliverables I will review at each milestone:
• Architecture and security document
• Running testnet prototype with documented API calls
• Source code (well-commented), build scripts, and deployment guide
• Final mainnet release, load-tested and signed off for production

Fluency with Bitcoin Core, SegWit, and best-practice key management is essential. When you respond, include a brief on similar Bitcoin projects you have shipped, your preferred toolchain, and a realistic timeline for the phases above.
