I’m finishing up a real-time Web3 game and need an experienced blockchain engineer to slot into our tiny, fast-moving team. The core engine—rendering, networking, and game logic—is already in place; what’s missing is the on-chain layer that turns it into a true metaverse experience. Here’s what the role looks like day to day: you’ll design, code, and test smart contracts, hook them into our existing Python back-end, and expose everything to the front-end so players can transact seamlessly. Whether we deploy on Ethereum, Binance Smart Chain, Polygon, or a mix is still open for discussion, so your insight on trade-offs, gas optimisation, and security will heavily influence the final architecture. Because the feature list ranges from NFT minting and trading to in-game item purchases and broader contract execution, I’m interested in someone comfortable jumping between solidity, web3.py, and the occasional Rust snippet when we experiment with sidechains. You’ll also help set up automated testing, basic audits, and deployment pipelines so we can push updates without drama. Deliverables (all source under MIT licence): • Production-ready smart contracts, fully unit-tested • Integration layer for our Python/Django API and existing React front-end • Simple CLI or script to automate contract deployment and upgrades • Concise technical docs covering setup, functions, and security assumptions Acceptance criteria: contracts pass test suite with >95 % coverage, mainnet-ready deployment succeeds on at least one EVM chain, and front-end calls resolve within target latency. If you thrive on variety, enjoy solving tricky multi-domain problems, and like the idea of shaping a full-stack metaverse platform from the blockchain up, let’s build something awesome together.
