Solidity Jobs

I'm looking for an experienced blockchain developer to create a smart contract for a DeFi application. The DApp will focus on staking and yield farming. Key Requirements: - Develop a secure and efficient smart contract - Implement staking and yield farming features - Ensure scalability and security Ideal Skills: - Expertise in smart contract development - Experience with DeFi protocols - Strong knowledge of blockchain security practices Please provide examples of previous work and relevant qualifications.

I need a clean, well-commented Solidity contract that accepts and forwards ETH payments on Ethereum mainnet (no ERC-20 support, no extra logic). The goal is to drop the file into my existing gateway flow, compile it in Remix or Hardhat, and deploy without adjustments. Here’s what I expect from you: • A single .sol file written for the latest stable Solidity version • Clear constructor or setup method to set the payout address • receive() / fallback() functions that safely capture any plain-ETH transfer • A withdraw function restricted to the payout address • Minimal gas usage and adherence to current best practices (OpenZeppelin style checks, re-entrancy guard where relevant) • A short README explaining compilation, deployment, and how to call each publ...

I’m building an end-to-end Web3 rental platform that lets users pay with real cryptocurrency. The core pieces—smart contracts, custody logic, dispute resolution, and an on-chain payment flow—are already sketched out, but I need an experienced technical project manager to turn those sketches into a production-ready system. Your day-to-day will revolve around three things: • Translating the product vision into a clear, sprint-based roadmap for the dev team • Owning the architecture decisions around smart contracts and off-chain services • Guiding implementation of an Ethereum-based payment flow and making sure every on-chain transaction is predictable, low-friction, and secure Because you listed Crypto payments as your strongest area and have hands-o...

Jeg ønsker å lansere en enkel, men robust utility-token på en populær EVM-kompatibel blokk­kjede (f.eks. Ethereum eller BNB Chain). Samtidig vil jeg ha en minimal staking- og mint-plattform som gjør det lett for brukerne å delta – og for meg å administrere tokenøkonomien. Kjernekrav • Smart-kontrakt for selve utility-tokenet (ERC-20 eller tilsvarende). • Staking-kontrakt som beregner avkastning løpende, men lar brukerne kreve ut belønningen manuelt fra dash­bordet. • Mint-funksjon tilgjengelig kun fra et eget admin-dash­bord slik at jeg kan øke sirkulasjonen når det er nødvendig. • Brukervennlig web-dash­bord som viser saldo, påløpte rewards o...

I am ready to take a theta-based trading idea from whiteboard to production and need a Web3 full-stack partner to carry the build end-to-end. The core features are already defined: real-time trading data flowing into the interface and automated trading algorithms executing on-chain. Everything will run on the Theta blockchain, so familiarity with Theta SDK, solidity-style smart contracts, and its RPC infrastructure is essential. Authentication will be wallet-based (e.g., WalletConnect or a custom Theta wallet integration) so users can sign transactions directly without traditional log-ins. Here is what I expect to see completed: • Responsive front-end (React/TypeScript preferred) that streams live market data and presents intuitive trade controls. • Smart contracts on Theta ...
