BNB Chain NFT Developer for Web3 Platform

We need a skilled BNB Chain NFT developer to create a custom ERC-721 token and set up a Bitbond whitelist. The role involves working with our team to ensure seamless integration and functionality. Ideal candidates will have experience in blockchain development and a strong understanding of NFTs. Job Title: BNB Chain NFT Dev: Custom ERC-721 and Bitbond Whitelist Setup Job Description: We are a movie-themed Web3 platform launching a high-priority dev cycle. Our token is already deployed. The presale pool and master whitelist will be managed directly inside Bitbond TokenTool. Your job is to build and deploy the custom NFT membership card infrastructure acting as the exclusive access gate for this presale. Ecosystem Workflow: Mint: Users mint a premium, looping MP4 digital membership card. Snapshot: At mint close, we extract holders to a CSV via online tools like Holders.at or Dune. Presale: We upload this CSV into Bitbond to unlock exclusive early token purchase rights. Deliverables: Solidity Contract: Secure, gas-optimized ERC-721 on BNB Chain with a Merkle Tree structure (bytes32 root) for a pre-approved free/discounted mint whitelist. Standard onlyOwner controls for withdrawals. IPFS Metadata: Custom JSON optimized for a looping 3D MP4 asset under 10MB, using dual-routing (animation_url for video, image for static preview thumbnails). Web Integration: Connect minting page UI to the contract and embed Bitbond's checkout iFrame widget into our dashboard. 4-Day Schedule: Days 1-2: Contract writing, Merkle Tree setup, IPFS formatting, and frontend connections. Day 3: Rigid testing and edge-case simulation on BNB Testnet. Day 4: BNB Mainnet deployment, BscScan verification, and widget integration. Budget: $150 Fixed-Price. Please link prior work with Merkle Trees or MP4 NFT metadata.
