I’m preparing to drop a new NFT collection on Binance Smart Chain and need a Solidity engineer to build the core smart contract. The contract must: • Implement BEP-721 (ERC-721 compatible) with a clean mint() function so I can release tokens in waves or all at once. • Embed creator royalties using the standard OpenSea-compatible interface (EIP-2981 or the BSC equivalent) so secondary-market fees route back to my wallet automatically. Because I plan to list immediately on OpenSea, Binance NFT Marketplace and Rarible, the finished contract has to expose every hook those platforms expect—correct metadata URI structure, royalty info and the usual supportsInterface declarations—so each marketplace recognises the collection without manual intervention. What I’m looking to receive: 1. The commented .sol contract, optimised and ready for verification. 2. A brief deployment script (Hardhat or Truffle) plus a README that lets me repeat the deployment on mainnet after testing. 3. Proof the contract shows up in the three marketplaces above (testnet screenshots are fine). If you’ve shipped BSC NFT drops before and can move quickly, let’s talk code and timelines.
