About the service
I develop smart contracts in Solidity for your specific task and handle the entire cycle myself: from the initial meeting with technical specifications to the moment a verified contract is published on the network. The work includes ERC-20 standard tokens, staking and reward pools, NFT collections on ERC-721 and ERC-1155, vesting and token lock schedules, as well as custom business logic for your product. I write each contract to be readable and predictable, with clear access control, event logging, and meaningful error messages so your team and future auditors can see exactly what the code does and why.
Testing doesn't take a back seat in my work. I cover every contract with a full suite of unit and integration tests, model edge cases: reentrancy, overflow and numerical boundaries, privilege abuse, external call failures, and run the code on a local fork of the target network before any deployment. Additionally, I conduct structured security self-review against a checklist of known vulnerabilities and a separate pass for gas optimization: reduce storage writes, pack variables, and rewrite hot paths so users pay less on every transaction. You get test reports and review notes along with the code.
Beyond the contracts themselves, I build a Web3 frontend that real people can use: wallet connection, transaction signing, live blockchain state, and clear feedback when a transaction is pending, confirmed, or failed. On output you get a complete product, ready to launch, not a lonely Solidity file. I'm equally comfortable with a rough idea and a ready specification, and keep you in the loop with regular demos on the test network so there are no surprises at launch.
