Quero lançar um token próprio, padrão TRC-20, na rede TRON. O ativo deverá se chamar “Moeda” e usar o símbolo “usdt”. Preciso do contrato inteligente completo, escrito em Solidity para a máquina virtual da TRON, já configurado para: • Transferências, aprovações e consulta de saldo dentro das normas TRC-20 • Compatibilidade imediata com TronLink, TRONSCAN e qualquer carteira que suporte tokens TRON • Verificação de código no TRONSCAN, exibindo nome, símbolo, supply e decimals corretamente Entrego o nome, símbolo e supply inicial; espero de você: 1. Código-fonte claro, comentado e sem dependências obscuras 2. Compila&cced...

looking for a smart contract developer who really knows their stuff and has at least 3 years of hands-on experience working with blockchain projects. You'll be helping build and deploy smart contracts, making sure everything is secure, efficient, and works smoothly. Ideally, you're comfortable working with Solidity and have experience with tools like Hardhat or Truffle, along with Web3 libraries. It's important that you understand how blockchain systems work and can spot potential security issues before they become problems. I'm looking for someone who's reliable, communicates well, and can take ownership of their work. If you've worked on DeFi, NFTs, or similar projects before, that's a big plus, feel free to share anything you've built. If this ...

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...

I'm seeking a skilled blockchain developer to assist in the development of a utility governance token project on the Polygon network.

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 ...
