Service details

I will develop, debug, and deploy professional Solidity smart contracts using Hardhat for Ethereum-based projects, whether you are building an MVP, launching a new token, creating NFT collections, or fixing issues in existing code.

\

What you will get:

• Secure, clean, and optimized smart contracts written with best practices

• ERC20, ERC721, ERC1155, and ERC721A token creation

• NFT minting logic with royalties using EIP-2981

• Hardhat unit tests, deployment scripts, and local testing setup

• Bug fixing, revert-error resolution, and gas optimization

• Support for testnet or mainnet deployment on Ethereum networks

• Clear documentation with step-by-step instructions for usage and maintenance


I focus on writing maintainable code, following security standards, and communicating clearly throughout the project. My goal is to help Web3 founders, startups, and development teams move fast while keeping their contracts reliable, scalable, and easy to extend for future upgrades.


Whether you need a quick fix, a prototype for investors, or a complete smart-contract setup for your application, I can tailor the solution to match your technical requirements, budget, and timeline.

Message me before ordering so we can discuss your project details. I respond quickly and am happy to review your idea or existing code before starting.
