Web3.js Jobs

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 ...

I need someone experienced with OpenZeppelin and Taxes? The task is to add Taxes and Anti Whale functionality and create my BEP-20 token. I need something simple and working. Please apply only if you can show some tokens portfolio with at least 2 OpenZeppelin contracts.

I want to represent my physical gold holdings on the Binance Smart Chain by issuing a BEP-721 token. The contract must fully comply with the BEP-721 standard so wallets and marketplaces on BSC recognize it, yet go beyond the basics by including three essential capabilities: easy transferability, an on-chain dividend-distribution function that lets me send BNB or BUSD to current holders, and a burn mechanism I alone can trigger when underlying gold is redeemed. Please write clean, well-commented Solidity, test it thoroughly with Hardhat or Truffle, and deploy first to the BSC testnet; after I confirm everything works, walk me through the mainnet deployment. Deliverables 1. Auditable BEP-721 Solidity contract with transferability, dividend payments, and burn controls implemented. 2. Un...
