Solidity Jobs

I’m looking for an experienced blockchain developer to build a smart contract for a decentralized finance (DeFi) application. The platform will focus on staking and reward distribution. The main objective is to create a secure, efficient, and scalable contract that allows users to stake tokens and earn rewards over time. Key responsibilities include developing staking mechanisms, implementing reward calculations, and optimizing the contract for low gas usage. You will also handle testing, debugging, and deployment. The ideal candidate should have strong experience in smart contract development (such as Solidity) and a good understanding of DeFi staking models. Knowledge of blockchain security best practices is essential. Bonus skills include experience with Layer 2 solutions, yie...

My DeFi protocol is code-complete and ready for public launch, but it cannot go live until an exhaustive penetration test confirms it is watertight. The scope is limited to the Solidity smart contracts powering liquidity pools, staking logic, rewards distribution, and governance. I need you to probe for the full range of threats—re-entrancy, flash-loan manipulation, oracle spoofing, unchecked arithmetic, gas griefing, privilege escalation, and any logic flaws unique to DeFi. A balanced mix of automated scanners (e.g., Slither, MythX, Echidna) and deep manual review is expected so no subtle issue slips through. Deliverables • Comprehensive audit report detailing every vulnerability, its severity, reproduction steps, and clear remediation advice • Proof-of-concept e...

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 ...
