I’m looking for a developer who can plug a Hierarchical Deterministic (HD) wallet manager into our existing backend so that every new user automatically receives an address derived from our single master seed. Scope (keep it lean and focused): • Generate and assign new HD-derived addresses when a user registers. • Enable sending and receiving funds only—no token swaps or contract calls. • Return simple balance and transaction-status queries. Tech landscape you should already know: • A mainstream EVM chain (we’ll confirm once we talk), with typical JSON-RPC calls. • Infura or Alchemy endpoints for node access. • Common crypto libraries such as ethers.js, web3.js, or bitcoinjs-lib, plus best-practice key handling. -familiarity with Laravel as well Integration touchpoints: Our backend (Laravel) exposes REST endpoints, so I’ll provide routes, DB models, and auth middleware; you wire in the wallet logic and hand back clean, documented functions or a lightweight service class. Deliverable: a concise code module (plus brief README) that I can drop into staging, run a quick smoke test, and start issuing addresses. Also you need to help on the integrarion. Also this is a peer to peer crypto platform.
