Ethereum Jobs

我正在筹备一款金融类 DeFi 去中心化应用，需要一位经验扎实的开发者负责整套智能合约开发。核心目标是用安全、可拓展的代码实现产品的业务逻辑，并确保合约能够顺利部署到主网。 工作重点 • 智能合约开发：根据功能需求完成 Solidity 合约（或适合的链上语言），涵盖核心交易逻辑、手续费、权限控制以及紧急暂停等安全机能。 • 单元与集成测试：使用 Hardhat / Foundry / Truffle 等主流框架编写全面测试，提高覆盖率，防止常见攻击向量（如重入、闪电贷）。 • 文档与部署脚本：提供清晰的 README、函数说明、部署与升级步骤，方便后续审计与运维。 • 安全与最佳实践：遵循 OpenZeppelin 标准库、Solidity 最新规范，避免整数溢出、重入等风险。如能协助对接第三方审计更佳。 我对交付时间没有硬性限制，重视质量优先。请在提案中简述相关 DeFi 项目经验、常用工具栈，以及能初步交付的里程碑。期待与你合作，共同打造一款安全可靠的 DeFi 产品。

I need an experienced blockchain coder to handle the entire smart-contract layer of my upcoming project. The priority is clean, secure smart contract development—from architecture through deployment—while keeping gas costs and upgradeability in mind. I have not locked in a chain yet, so if you are comfortable on Ethereum, Binance Smart Chain, Polkadot, or can justify another EVM-compatible network, please outline why it fits. I’m equally open on the contract’s purpose: token logic, an NFT framework, or a back-end for a dApp are all in scope; the key is that the code is solid and audit-ready. Deliverables • Full Solidity (or relevant) source with in-line comments • Comprehensive unit tests and deployment scripts (Hardhat or Truffle preferred) •...

I am currently looking for someone who can work on the blockchain to build out a smart contact website for a very high end domain name that ive owned for years. Now is the perfect time to build this out and I'm looking for a partnership to build this out. I have the design team already in house but need a Developer in the space that can actually handle this type of a build out. ONLY APPLY IF YOU PERSONALLY WORK ON THE BLOCKCHAIN & ARE COOL DOING A PARTNERSHIP DEAL WHERE YOU OWN PART OF THIS.

I need a production-ready smart contract written for Ethereum that will handle straightforward financial transactions, then wrap it in a clean single-page dApp so end-users can interact with it without touching the command line. The contract must be solidly coded in Solidity, thoroughly tested, and deployed to the mainnet once we finish our reviews. On the front-end I want a lightweight React (or similar) page that talks directly to the contract. Wallet integration is essential—MetaMask and any other common Web3 wallets should connect seamlessly so users can approve, send, and monitor transactions. A clear, searchable transaction history pane is the second must-have so people can verify their activity in real time. Beyond those core pieces I have several additional features in min...
