Rivac LabsSolidity Smart Contract Engineer
Smart contract bugs are uniquely expensive because deployed contracts often can't be patched, and a single vulnerability can drain funds directly — there's no rollback, no incident response, just an immutable record of the mistake. We write secure, gas-optimized EVM smart contracts and build out DeFi protocol logic with security as the primary design constraint, not an afterthought before deployment. This is for teams building on-chain products who need contracts written by someone who treats every line as a potential attack surface. You get audited, gas-conscious contracts, not code that merely compiles and passes a happy-path test.
How We’d Approach This
A clear, staged plan — not a black box
- 1
Define the contract's exact economic logic and threat model before writing a single line of Solidity.
- 2
Build and test the core contract logic against a comprehensive test suite, including adversarial scenarios.
- 3
Review the contract with a security-focused read-through — and external audit where funds are at stake — before deployment.
- 4
Deploy with gas optimization verified and monitoring in place for on-chain contract activity.
