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 ...

I want to launch a brand-new crypto coin on its own custom blockchain, then build out everything needed for people to actually use it. The work begins with the chain itself: consensus design, node software, smart-contract capability, a block explorer, and clear tokenomics that leave me free to adjust supply or governance later on. Once the chain is live, I need a companion wallet / exchange app that runs smoothly on iOS, Android, and the Web. Users must be able to store, send, receive, trade, and convert the coin in-app, with security features such as biometric login, 2-factor authentication, and optional cold-storage integration. Finally, the coin has to power in-game purchases inside a first-person-shooter that also offers a lighter casual mode. Think weapon skins, character upgrades, ...

I’m in the full-development stage of a browser-based RPG and now need a developer who can weave solid gameplay together with Ethereum-powered Web3 features. The core game loop, narrative arcs, and art style are already mapped out; what’s missing is the code that turns those ideas into a living, playable experience directly in the browser. Your focus will be to: • Build the front-end gameplay layer (HTML5, WebGL, or your preferred JS game framework) and connect it to a secure back-end. • Integrate Ethereum smart contracts for on-chain assets such as character NFTs, item drops, and marketplace trades. • Ensure wallet connectivity (MetaMask or similar) and smooth signing flows so players stay immersed. • Optimise for quick load times and responsive controls ac...
