ERC-721 Solidity Contract Creation
Budget: $30 – $250 USD
I need an experienced Solidity developer to craft a production-ready ERC-721 smart contract that follows the latest OpenZeppelin standards and best security practices. The contract should compile cleanly with Solidity 0.8.x, be easily upgradeable or extensible, and keep gas costs in mind.
While I will ultimately decide on the exact feature set during our discussion, the foundation must include the core ERC-721 logic plus room for optional extensions such as metadata, enumerability, royalty support, and pausable or burnable functionality. Clear, well-commented code and unit tests (Hardhat or Foundry preferred) are essential so I can audit and maintain the project long term.
Deliverables I expect:
• Complete Solidity source code with import paths pinned to specific OpenZeppelin versions
• Automated test suite covering minting, transfers, and edge-case failures
• A short deployment script and README explaining environment setup, contract parameters, and post-deployment verification steps
• One post-handover review session to walk through the code and answer any integration questions
If you have previously shipped ERC-721 contracts to mainnet or major testnets, please mention that experience and any libraries or design patterns you favour. I’m ready to start as soon as I find the right fit and will move quickly on milestones for code delivery, testing, and final walkthrough.
