About this Gig
Need a smart contract that brings your Web3 project closer to launch? I help you turn your requirements into functional, tested Solidity contracts that are ready for integration into your application.
What I can deliver:
- Custom smart contracts: Implement your required business logic and protocol features.
- Token contracts: Build ERC-20, ERC-721, and ERC-1155 contracts for your project.
- DeFi functionality: Develop staking, lending, vault, and other protocol components.
- Contract improvements: Fix bugs, add features, and optimize gas usage.
- Testing and integration: Test contract behavior and prepare contracts for dApp integration.
- Deployment and documentation: Deploy contracts and document the implementation when included in the agreed scope.
I work with Solidity and Foundry across Ethereum, Base, Arbitrum, and other EVM-compatible networks.
The goal is to deliver contract code that meets your requirements, works as expected in testing, and is ready for the next stage of your project.
Message me with your requirements and target network so we can define the scope and select the right package.

FAQ
What blockchain networks do you support?
Ethereum, Base, Arbitrum, Polygon, Optimism, BNB Chain, Avalanche, zkSync, Scroll, Linea and Sonic.
Do you develop both new and existing smart contracts?
Yes. I can build new contracts, improve existing code, fix bugs, optimize gas usage, or add new functionality.
Do you include testing?
Testing is included according to the selected package. The exact test coverage and acceptance criteria will be agreed before work begins.
Do you deploy the contract?
Deployment can be included when agreed in the order scope. Network fees, access requirements and deployment responsibilities will be clarified beforehand.
Do you provide smart contract audits?
This Gig focuses on development and testing. Development checks are not equivalent to an independent security audit. Please contact me if you need a separate security review.

I went into this with Sabi having limited expectations. Just wasn't sure. The expectations I did have were immediately shattered - and then some. Knowledgeable and kind, with no sales push, Sabi provided more information than I could have hoped for. When I am ready to start this project, Sabi is the only choice to help me build it.
