Solidity DEX Contract Development
Budget: $25 – $50 USD
I need an experienced Solidity engineer (3 + years on main-net projects) to architect, write, test, and deploy a brand-new suite of smart contracts for a DeFi platform. Your core mandate is building everything from scratch, so there is no legacy code to fight with—only green-field development.
Scope of work
• Token creation and on-chain management compliant with the latest OpenZeppelin standards.
• Complete DEX layer focused on reliable token swapping, wired for future expansion into liquidity pooling and a full order engine.
• Staking and rewards logic that can be tuned by governance parameters we will expose later.
You will own the full contract lifecycle: specification, implementation, test coverage (Hardhat/Foundry), gas optimisation, and main-net deployment. Expect to interface directly with our front-end team via clean ABI definitions and event design.
Deliverables
– Audited Solidity contracts (0.8.x) with 100 % unit-test coverage.
– Deployment scripts and configuration for multiple EVM networks.
– Brief technical hand-off document so future contributors can extend the codebase.
Success is measured by secure compilation with no critical issues, passing test suites, and a smooth swap of two ERC-20 test tokens on a public testnet.
If you have shipped token-swap or other trading logic before, let me see it—I move quickly when the fit is right.
