I will help you design, develop, test, and integrate Solidity smart contracts for Web3 applications, tokenization platforms, NFT utilities, ERC-20, ERC-721, ERC-1155, and Polygon/EVM-based projects.
I can help with:
- Solidity smart contract development
- ERC-20 / ERC-721 / ERC-1155 contracts
- Asset tokenization logic
- NFT certificates and proof-based token systems
- Hardhat project setup
- Deployment scripts
- Role-based access control
- Contract integration with frontend/backend
- ethers.js / web3.js interaction scripts
- Testing and debugging
- Gas and logic optimization
- Preparing contracts for audit review
My experience includes building GSun, a Web3 energy proof system that connects physical solar generation data with blockchain proofs, ERC-1155 energy batches, NFT-based certificates, Polygon/Sepolia deployments, oracle-style data flow, and backend/API integration.
I can start with a small paid milestone: review your requirements, propose the contract architecture, and prepare the initial implementation plan.
Important: I can prepare contracts for audit and follow security best practices, but I do not replace a professional third-party security audit.
