Blockchain Jobs

We are building a next-generation EVM-based ecosystem and are looking for a talented Blockchain Engineer to help develop and scale our platform. This includes working on smart contracts, backend infrastructure, and integrations that power our trading systems, staking mechanisms, and overall protocol functionality. The ideal candidate should have strong experience in Web3 development, particularly within EVM-compatible environments, and be comfortable working with complex, data-driven systems while maintaining high standards for security, performance, and scalability. Key Responsibilities: - Design, develop, and deploy smart contracts on EVM-compatible blockchains. - Build and maintain backend services that interact with blockchain networks. - Integrate smart contracts with frontend appl...

AmonixPlay is our flagship multi-chain Web3 platform that blends AI-driven logic, robust blockchain security, and Play-to-Earn mechanics. I’m now expanding the development team with someone who lives and breathes blockchain scalability, particularly cross-chain interoperability. Your focus will be hands-on development. I already have high-level architecture and business logic in place; what I need is code that lets assets and data move seamlessly between chains without bottlenecks or security gaps. You’ll work in a remote-first environment where schedules are flexible and contributions are measured by the quality and reliability of what ships to production. Key objectives you’ll tackle: • Build and optimise cross-chain bridges or messaging layers that plug into o...

I’m moving the wider DeFi & Web3 project forward by tackling the staking layer first, and I need a developer who can take it from architecture to main-net launch. The immediate goal is to deliver staking contracts that support our own native token alongside key stablecoins, all managed through multiple independent pools that can run different APRs and compounding rules. Here’s what the first milestone looks like: • Write and test Solidity (EVM-compatible) contracts for multiple staking pools. • Enable deposits, withdrawals, and reward calculations for both native tokens and stablecoins. • Build a simple dashboard or CLI so I can monitor TVL, pool-specific metrics, and user positions during testing. • Provide unit tests, coverage reports, and a b...

I’m ready to move from architecture notes to on-chain code for a new DeFi lending and borrowing protocol that will live on EVM networks. You’ll take ownership of the Solidity layer—designing, writing and testing the smart contracts that manage deposits, collateral, interest accrual, and liquidations. At a minimum the contracts need to: • compile under Solidity 0.8.x with no warnings • follow OpenZeppelin standards for upgradeability and access control • integrate price feeds (e.g., Chainlink) for real-time collateral valuation • emit clear, indexed events for every state-changing action • be covered by a Hardhat or Foundry test suite that reaches 90 %+ branch coverage • ship with deployment scripts and a concise markdown do...

I want a real-time, step-by-step walkthrough for moving my Ethereum from Trust Wallet into my wallet and then off-ramping the funds to my linked bank account. Both wallets are already set up and verified, so we can jump straight into the transfer process. During a live screen-sharing session I need you to: • Help me choose the correct ERC-20 network in Trust Wallet, generate and double-check the matching deposit address, and confirm the on-chain transaction. • Explain gas fees, typical confirmation times, and how to monitor progress on Etherscan. • Show me how to swap or sell the received ETH inside and initiate the fiat withdrawal to my bank, highlighting any limits or timing quirks. • Point out common mistakes and security best practices so I avoid irrevers...

I have a five-day window to stand up a brand-new blockchain ecosystem. You may fork whichever codebase you are most comfortable with from EBLA (Taraxa), BlockDAG, or Hedera—the goal is simply to deliver a fully functioning network, not a specific brand. Scope of work • Fork the chosen network and spin up both a mainnet and a testnet, each with three seed nodes and the corresponding validator nodes. • Ship a block explorer that tracks the fork in real time. • Build a web-based multisig wallet featuring multi-device support, multi-user approval flows, and complete transaction history views.

Project Title:** Need PHP Developer for Automated USDT (TRC20) Payment Gateway Integration **Project Description:** I am looking for an experienced PHP developer to integrate a custom, fully automated USDT (TRC20) payment gateway into my existing PHP script. The system needs to be secure, automated, and designed with privacy in mind. **Key Requirements:** * **Unique User Addresses:** The system must dynamically generate a separate, unique USDT (TRC20) deposit address for each individual user on the platform. * **Automated Payment Detection:** The script should automatically monitor the Tron blockchain (e.g., using TronGrid API or a similar method) to verify incoming transactions. Once a deposit is confirmed, it should automatically credit the respective user's account balance in the M...

I want to run a simple, real-world check that a USDT deposit from Binance to another platform without issues. The sole objective is to ensure the transfer lands successfully.

I need a complete, production-ready solution that covers both sides of the project: 1) A new coin that can be created, deployed, and instantly tradable on a decentralized exchange, with its live liquidity metrics clearly visible. 2) A companion wallet application built around a modern interface that feels intuitive from the first tap. The wallet must: • keep a clear transaction history, • hold several currencies (not just my new coin), and • remain exceptionally easy for new users to navigate. My priority is a smooth user flow and accurate liquidity data pulled directly from the blockchain. I am flexible on the underlying chain and open to your recommendation, provided it supports low-cost, fast transactions and reliable DEX integrations. Acceptance criteria ...
