Smart contract vulnerabilities are expensive. I build custom, gas-optimized Solidity smart contracts backed by a security-first methodology. I do not just write code; I mathematically test it. Using Foundry, I subject every contract to rigorous unit, fuzz, and invariant testing to catch edge cases before deployment.
From custom DeFi protocols to fully autonomous Chainlink integrations, you get production-grade infrastructure that is secure, verifiable, and efficient.
What You Get:
- Custom Smart Contracts: ERC-20, ERC-721, custom DeFi logic (staking, lending, AMMs), or autonomous operational contracts.
- Chainlink Integrations: Seamless implementation of Chainlink VRF (v2.5) for provable randomness and Chainlink Automation for autonomous on-chain actions.
- Comprehensive Foundry Testing: A complete test suite aiming for 100% line, branch, and function coverage, including fuzz testing for random inputs and invariant testing to enforce protocol solvency and accounting integrity.
- Deployment & Verification: Clean deployment scripts (handling mock setups for local Anvil environments and live testnet setups) and Etherscan source code verification.
Tech Stack: Solidity, Foundry, OpenZeppelin, Chainlink (VRF/Automation/Oracles), Ethernaut Security Principles.
Why Work With Me: I prioritize robust security over rushed deployments. I have built fully autonomous, provably fair decentralized raffles and complex lending protocols that maintain 100% test coverage against reentrancy, negative-balance attacks, and access control flaws. I hold Cyfrin Updraft certifications in Solidity Development, Advanced Foundry, and Web3 Wallet Security.
Requirements for the Buyer:
Please provide your project specifications, tokenomics, required external integrations (like Oracles or specific DEXs), and any existing architectural diagrams.
