About this Gig
I develop secure and well-structured Solidity smart contracts and Web3 integrations for real-world applications.
This gig is suitable for startups, developers, founders, and teams that need custom blockchain functionality, smart contract development, or integration with an existing frontend, backend, or API.
I can help with:
- Custom Solidity smart contracts
- ERC-20, ERC-721, and ERC-1155 implementations
- Staking, escrow, payment, and access-control logic
- Smart contract fixes and feature additions.
- Web3 integrations with frontend or backend applications
- API development for blockchain-based systems
- Wallet and contract interaction
- Contract deployment scripts
- Testnet deployment assistance
- Unit testing and debugging
- Smart contract code review and improvement
- OpenZeppelin-based implementations where appropriate
My focus is on clean code, clear scope, maintainability, and practical integration.
Important: gas fees, hosting, RPC/provider costs, and other third-party expenses are not included. Code review included in this gig is not a formal third-party security audit.

FAQ
Do you deploy smart contracts to mainnet?
I can assist with depoyment, but gas fees and other third-party costs are not included. Mainnet deployment should be discussed before ordering.
Do you provide smart contract audits?
I can review code, identify common issues, improve structure, and add tests. This gig does not provide a formal third-party security audit.
Can you work with an existing smart contract?
Yes. I can fix bugs, add features, refactor code, improve tests, or integrate an existing contract with your application.
What counts as one feature?
One feature is one clearly defined functional requirement, such as minting, pausing, whitelist access, withdrawals, staking rewards, or one API integration. Larger systems may count as multiple features.
Can you integrate the contract with my website or backend?
Yes. The Premium package includes one frontend or backend/API integration. Larger integrations can be handled through a custom offer.
Do you support cross-chain projects?
Potentially, but cross-chain development is not included in the standard packages and must be discussed separately.
Should I contact you before ordering?
For Standard and Premium, yes. Please message me first so we can confirm the requirements, complexity, and exact scope.
