Web3.js Jobs

I’m building a BNB Smart Chain dApp and need an experienced full-stack Web3 developer to take it across the finish line. Your first mission is smart-contract development, with the referral and level system at the very top of the queue. Once that is solid, we’ll move on to staking/vesting and an NFT + ATA token suite that enforces minting restrictions, level-gated minting, and tight token-supply management. The front end is already built in (TypeScript) and wired with Wagmi/, but a few hooks still need to be connected and several UI/UX flows polished—especially around wallet connection and transaction feedback. After contract deployment, I’ll rely on you to bridge everything cleanly into the existing React components, squash lingering bugs, and streamline the user ...

I have an almost–finished Web3 application running on BNB Smart Chain and need an experienced engineer to wrap up the last mile. The heavy lifting is on the contract side, but a clean hand-in demands tight coupling with the existing React/TypeScript frontend. What still needs doing • Write production-ready smart contracts for a referral & level system, staking and vesting mechanics, a level-gated NFT mint, and the accompanying ATA utility token. • Deploy, test, and wire those contracts into the current codebase through Wagmi / connectors. • Guarantee seamless Metamask, WalletConnect, and Trust Wallet interaction, including clear transaction states and error handling. • Close out a handful of UI bugs, polish the UX, and verify that every on-chain ac...

I have a new Web3 idea ready to move from concept to code and I’m seeking an experienced blockchain developer to guide and build the entire solution with me. Because the project is still early-stage, I’m open on the specific chain, tech stack, and even the exact feature set—we’ll define those details together during an initial discovery call. What I do know is that the end product will rely on smart contracts, a dApp front end, and secure wallet interaction, so familiarity with Solidity or similar contract languages, , and modern front-end frameworks is essential. Here’s how I’d like to structure our collaboration: – First, a short technical workshop where you assess my concept, recommend an appropriate blockchain (Ethereum, BSC, Polkadot, or ...

I need someone to audit my token code I created with OpenZeppelin and AI? I implemented taxes and max wallet but I don't see taxes into my taxes wallets. I need someone to audit and maybe fix the issues and explain it. It is one hour of work I guess.

I’m assembling a freelance roster of seasoned Solana engineers to push a new decentralised application from idea to mainnet. The role centres on end-to-end DApp development: writing and auditing on-chain Rust programs, wiring them to a TypeScript/React front-end through Anchor or @solana/, and handling deployment, testing and optimisation so the final product is fast and fee-efficient. If you have shipped production Solana work before, please include links or GitHub repos that clearly show what you built and the parts you owned. I’ll review those examples first to decide who moves forward. We will work milestone-by-milestone; as soon as the initial scope is delivered (fully functional features, commented code, concise hand-off docs), I have follow-up tasks ready. Comfortable ...
