Ethereum Jobs

Several small but important online tasks are ready to be delegated and I need them handled locally from within Egypt so time-zone and cultural context remain perfectly aligned. The work will vary week to week—one assignment might involve formatting product data in Google Sheets, another could be drafting a short blog post in Arabic or English, or preparing a quick Canva visual for a social post. I always supply clear briefs, examples, and deadlines, and I value proactive communication through WhatsApp or Slack. Strong command of Microsoft Office or Google Workspace, basic design familiarity (Canva, Photoshop, or similar), and reliable high-speed internet will make the collaboration smooth. If you already work comfortably with WordPress, Shopify, or simple research tools, do mention ...

I’m ready to commission a production-grade DeFi dashboard that behaves much like , but purpose-built for my needs. The front-end must be written in React (TypeScript preferred) and speak directly to live Ethereum nodes—no mocked or hard-coded data. From the first render the app should query real-time farming stats, then let users act on them through MetaMask, WalletConnect, or Coinbase Wallet. Core workflow • Connect wallet → fetch on-chain positions → allow Compounding, Harvesting, and Rebalancing in a single click, signing the transaction in the connected wallet. Gas status, pending state, and success/error toasts need to feel snappy and informative. • Multicall batching or similar optimisations are essential so the UI stays fast even when reading doz...

We already have a complete Figma design for the landing + presale website of our token project.

I already have a live Solidity swap contract paired with its own ERC-20 token. Before I push the next release, I need an experienced smart-contract developer to jump in, modify the existing swap logic, and make sure both contracts work seamlessly together. The core tasks are: • Update and expand current functionality – I have a short list of new features to add, plus a few existing functions that need refinement for better UX and gas use. • Hunt down and fix the bugs that have shown up in testing and on-chain analytics. • Refactor any overlapping code in the token contract so it remains fully compatible with the refreshed swap contract. I’ll provide the current repos, unit tests, and a changelog of desired upgrades. Deliverables are the updated Solidity fil...

I'm seeking an experienced blockchain developer to help with smart contract interactions and wallet recovery. Key Tasks: - Access legacy contracts on Ethereum, Binance Smart Chain, and Polygon. - Resolve gas estimation issues.

I need a smart contract developer to build a TRC20 token on the Tron network that goes beyond simple transfers. The contract must support minting and burning functions and incorporate a staking mechanism that distributes rewards on-chain. An admin role is required so that I can manage mint, burn, and staking parameters without touching user balances directly. I haven’t decided whether I’ll deploy it myself or have you handle deployment, so please quote for both scenarios and outline any additional steps or tooling you would need (TronBox, TronGrid, Remix-Tron, etc.). To make expectations crystal clear, here’s what I consider a complete delivery: • TRC20 contract code with transfer, mint, burn, and staking logic • Proper admin role implementation (OpenZeppeli...

I’m gearing up to build a production-ready set of smart contracts and need an experienced developer to bring the on-chain logic to life. The core of the assignment revolves around architecting, coding, and testing the contracts themselves; tokenomics, dApp front-end, and broader infrastructure are handled elsewhere. To streamline selection, I’d like to see concrete past work—live contracts, GitHub repos, audits, or anything that proves you’ve shipped secure Solidity code before. Please highlight any experience with Truffle, Hardhat, Foundry, or comparable frameworks, plus the security tools you rely on (Slither, MythX, Echidna, etc.). Gas optimization and adherence to current best practices (e.g., EIP-2535, OpenZeppelin upgradeable patterns) will weigh heavily in m...

I’m preparing to launch a beta for a fully on-chain poker room and need an expert who can take charge of the blockchain layer. The web front end and core poker logic are already mapped out, but the smart-contract stack that makes the game provably fair, secure, and multi-chain ready still needs to be built, tested, and deployed. Scope of work Your main mission is to design, write, and integrate the smart contracts that power: • NFT-based avatars (ERC-721) minted and managed in-game • Tokenized poker chips (ERC-20) that handle buy-ins, pots, and cash-outs • Seamless crypto transactions across Ethereum, BNB Smart Chain, and Polygon—one wallet, three networks, no friction Alongside those core pieces, the contracts must expose hooks for staking rewards and f...

I’m the CTO at CoinZoom and I’m kicking off a three-month build of a company-wide ERP that will consolidate every internal business workflow into a single web application. The main objective is simple: streamline all of our internal processes. Tech stack is locked in: on the front end, Node.js with Express on the back end, and MySQL for data persistence. On top of that, the platform will include an automated crypto-based salary engine, so hands-on blockchain experience is non-negotiable. Key features we’ll deliver together: • Real-time analytics and reporting • Automated workflows • Customizable dashboards You’ll collaborate with our in-house engineers on sprint-based milestones, commit to clean, well-documented code, and partic...

I’m ready to purchase USDT for the first time and I’d like someone to walk me through the complete, step-by-step process from funding my account to seeing the tokens in my wallet. I haven’t committed to a specific exchange yet, so you’re free to suggest Binance, Coinbase, Kraken, or any other reputable option if it makes the walkthrough smoother. Here’s what I expect from you: • A real-time session (voice, video, or live chat) where you demonstrate each step and answer questions as we go. • Clear explanations of deposits, order placement, withdrawal to a personal wallet, and any security points I shouldn’t overlook. • A concise summary afterward so I can repeat the process on my own. Once the transaction is successfully completed a...

I’m building a finance-focused DApp and need a Solidity expert to craft the core smart contracts. The immediate requirement is a secure, audit-ready transferFrom-style function that lets users move assets between wallets without exposing them to re-entrancy or allowance-drift risks. The code must be: • Written in Solidity following the latest compiler version and OpenZeppelin best practices. • Fully covered by automated tests (Hardhat or Truffle) that demonstrate correct behaviour under normal, edge-case, and malicious scenarios. • Optimised for gas and easy to upgrade, as I may expand into lending, yield farming, or staking later. Deliverables 1. Production-ready smart contract source code. 2. Deployment/​migration scripts for testnet and mainnet. 3....

I’m ready to launch a BEP20 token on Binance Smart Chain and need an experienced Solidity developer who can deliver a clean, audited contract and guide me through deployment. Scope of work • Build a BEP20 smart contract that includes: – Airdrop distribution logic that automatically allocates tokens proportionally to each holder’s balance (“based on the amount held” method). – DeFi liquidity provision via liquidity pools, with functions to add/remove liquidity and lock LP tokens as needed. – Staking and rewards so holders can lock tokens and earn native-token rewards on a configurable schedule. • Write and run unit tests covering transfers, airdrop events, staking, and liquidity functions. • Deploy the contract to BSC m...

I want a brand-new TRC-20 token on the Tron network that mirrors USDT in decimals (6) and symbol behavior, yet is entirely my own asset. The contract must be written and deployed from scratch; I do not have an existing code base. Key objectives • On deployment, my wallet should immediately display a total balance of exactly 1,000,000 tokens. • The token must move freely to and from any compatible wallet (Trust Wallet, TronLink, etc.) without restrictions or additional steps. • The USDT coin you will make has to be like a 1on1 copy from the real USDT, so indistinguable. Scope of work 1. Write the Solidity (or TRC-20-compatible) smart contract. 2. Deploy it to the main Tron network and verify it on TronScan so the code is publicly visible. 3. Send the entire in...

I am refining a custom subgraph on The Graph for Uniswap v3 and need an experienced hand to guide the process rather than to build everything from scratch. The goal is to be certain the architecture, mappings, and queries will scale before my team invests further development time. Scope of the advice • Indexing coverage must include: transactions & swaps, liquidity positions, pool statistics, plus both the overall TVL in USD and the TVL of in-range positions only. • I already have contract ABIs and a draft schema; what I need is a critical review of the design, suggestions for AssemblyScript mapping optimisations, and pointers on how best to calculate the two TVL metrics without bloating the node. • Performance tuning tips around entity ordering, handling large bl...

I’m expanding our core team for an upcoming Web3 gaming and staking platform and I’m looking for a seasoned Blockchain Developer who lives and breathes Solidity. You’ll design, code, and audit smart contracts that power gameplay mechanics, reward distribution, and staking pools. Your past success building DeFi platforms will serve you well here, as many of the token-economy pieces—liquidity incentives, yield logic, and on-chain governance—map directly into our game loop. What you’ll tackle • Architect and write Solidity contracts for game assets, staking, and treasury functions • Integrate contracts with an Ethereum-based backend and front-end dApp (React + ) • Conduct rigorous unit, integration, and security testing before every ma...
