Ethereum Jobs

I need a complete installation and configuration of a private Hyperledger Besu network whose main job is reliable data storage and sharing. I have servers ready (cloud or on-prem) and want a clean, repeatable setup that lets me add nodes later and expose standard JSON-RPC and WebSocket endpoints. Scope of work • Install the latest stable Besu release on 3+ nodes (validator and non-validator) • Create a custom genesis file, bootnodes list, and network ID • Enable data-storage–focused consensus (IBFT or Clique—whichever you recommend for fast confirmation) • Configure basic account permissioning and privacy groups if they help our data-sharing use case • Expose HTTP & WS APIs with CORS and authentication where needed • Deploy a sampl...

I have a bep20 token and require 2 options that both need to be included in the smart contract so users have 2 options to claim tokens: 1) Simple smart contract function on bsc where users send bnb to the contract address and receive project tokens in exchange. 2) Need users to interact with the smart contract by using a web3 function as simple as possible and get a set amount of tokens per claim and I need in this contract to take a small fee on top of gas that is to be deducted when user calls contract to claim tokens. This small fee will be sent to admin wallet for each transaction but this will not include gas (small fee will land in admins wallet each tx). I need for this all to be 1 transaction for the user so they call the contract from my website and metamask,...

I want to develop solid, real-world skills in crypto trading and I’m starting from a beginner’s standpoint in technical analysis. I can read basic candlestick charts but that’s where my confidence ends. I need a seasoned trader who can walk me through the core concepts of technical analysis—interpreting price action, spotting reliable patterns, and understanding indicators such as moving averages, RSI, MACD, and Fibonacci levels in the context of Bitcoin, Ethereum, and the major alt pairs I follow on Binance and Bybit. My goal is to progress from theory to practical application, so live screen-share sessions on TradingView (or a comparable charting platform you prefer) are essential. I’d like you to demonstrate how you build a trade thesis, set entries and ex...

Freelancer Needed – Advanced On-Chain Gambling Protocol with Liquidity Pool, Fully Operational Arbitrage Engine, Railway Backend Compatibility, and Optional Complete Automation I am seeking a highly experienced blockchain developer to finalize, secure, and deploy my on-chain Gambling system.

This is not a basic betting application. The objective is to build a mathematically sound, automated, liquidity-backed on-chain betting system that functions independently and does not require manual...
