Project description:
"I'm building a hot wallet connected to 25 separate blockchains. The project is server-side: secure key management, high-throughput transaction processing, and seamless connectivity to an RPC gateway for each network or its equivalent. In addition to basic send and receive functionality, the backend also needs endpoints for staking flows and public DeFi/DApp calls, so the frontend can offer these features without additional hops.

All send, receive, and swap transactions are handled through an API with the platform [login to view URL] so we don't have to build blockchains for each cryptocurrency. I already have the frontend resources in place, so what I need is to build, implement, and enhance the backend layer itself—such as designing the API, the database schema for balances and metadata, backend staff for confirmations, and an audit-ready security model for hot key storage.

Outputs
• Production-ready source code and configuring environment
• API documentation (OpenAPI/Swagger or similar) covering all wallet, storage, and decentralized finance pathways
• A concise deployment guide and a test suite demonstrating successful transactions across the full list of 25 chains

I am open to any language and stack—TypeScript/Node, Go, Rust, or similar—as long as it is robust, well-tested, and easy to maintain." (client-provided description)
