...and a React + Node.js front end; I’d like you to extend and harden that foundation. Core scope • Write, test, and deploy all Solidity contracts that power gameplay logic, staking pools, reward distribution, and the affiliate/referral system. • Create a gas-efficient contract architecture, with clear upgrade paths where practical (proxy pattern or similar). • Integrate mainstream wallets—MetaMask first—via and extend to WalletConnect / Coinbase Wallet as time allows. • Build the React components needed for seamless in-browser gameplay, real-time balance updates, and transaction prompts. • Develop the Node.js back-end utilities (cron jobs, webhook listeners, analytics hooks) that index on-chain events and feed them back to the ...

...browser-based dashboard. The core idea is simple: create a TRC20 token that I can spin up instantly, move freely across major wallets, keep alive for at least 30 days, and spend on betting platforms that accept TRON assets. Key functions I must have • Token creation & on-chain management: One-click deploy, adjust supply, pause/restore, and burn. • Wallet integration: seamless send/receive in MetaMask, Trust Wallet, Coinbase Wallet, and Binance Wallet without extra configuration. • Transaction tracking: real-time status, confirmations, and expiry countdown visible in the UI. Technical freedom is yours—Solidity (or Tron’s Solidity-like variant), JavaScript/TypeScript, Python, Node.js or any stack you prefer—so long as you deliver an exec...

...functional proof-of-concept. • React is baked in (the chosen framework); designs are still coming together, so some screens will arrive progressively. • Solidity contracts compile and deploy, but they still need a proper security pass, gas-cost tuning, and upgradeability considerations. • Only WalletConnect is required for the first release, yet the codebase should remain flexible enough to add MetaMask or Coinbase Wallet later. First milestones • Finalise and harden the Solidity contracts, add a complete test suite, and create clean deployment scripts. • Wire up WalletConnect in the React client, ensuring seamless connection, signature, and network-switching flows. • Extend the Node/Express layer to expose any missing endpoints and prot...

I’m building a decentralised portal that lets students handle every administrative step—from opening a profile to paying tuition—directly on Ethereum. The site must: • let users connect a MetaMask (or any Web3) wallet, create a personal profile and register as a student • allow real-time course browsing, enrollment and on-chain fee payment in ETH or an ERC-20 we define • route each payment and enrollment request to an admin dashboard where staff can verify KYC details, approve or reject registrations and manage fee settlements • store all critical actions in Solidity smart contracts, fully tested and verified on Etherscan, with events that keep the front-end in sync • give admins rich analytics—total fees collected, outstandi...

...records every chip and token—your job is to connect on-chain activity to that ledger with real-time confirmations and webhook callbacks. Key requirements • End-to-end handling of Deposits, Withdrawals, and Transfers between wallets. • Automated sweeps batching user balances into predefined hot / cold addresses on configurable thresholds. • Support for common browser and mobile wallets (e.g., MetaMask, Coinbase Wallet, Trust Wallet) while remaining flexible enough to plug additional providers later. • Clear, signed messages so users never have to paste addresses by hand. • Comprehensive unit tests plus a staging script so QA can replay typical casino flows. Acceptance criteria 1. A user can deposit BTC, ETH, LTC, or SOL and see confirme...

...main purpose is investment, so it must inspire confidence from day one. The job starts with writing and deploying a secure, upgrade-ready smart contract on BNB Chain, followed by verifying it on BscScan and setting up initial liquidity. Once the token is live I need a lightweight trading interface that supports live trading against BNB. A clean web front end (React or similar) that plugs into MetaMask, Trust Wallet, and WalletConnect is fine as long as trades execute in real time and the order book or swap quotes refresh without delay. Extras such as detailed transaction history and advanced user management can wait for phase two; for now the priority is a smooth, functional live-trading experience. Please show previous blockchain or DeFi experience when you reply—links...

I’m launching a new memecoin and need the public-facing website to look and feel as credible as any top-tier crypto project. The priority right now is the web platform itself; mobile apps and broader social campaigns can follow once a solid site is live. Core requirement The site must include a fully functional transaction wallet integration so visitors can connect MetaMask (or other Web3 wallets), see their balance, and buy or sell the token directly. Everything should be wrapped in a professional, sleek UI—clean typography, restrained colour palette, quick loading animations—so even though the coin is playful, the site inspires trust. What I picture • Landing page that highlights the coin’s story, tokenomics and roadmap • Live contract add...

I want a small, self-contained PHP script with a browser-based GUI that sits on my Linux server and lets me swap my own ERC-20 token (the one I already hold in MetaMask) for ETH on the Ethereum Mainnet. The interface should: • Detect the connected MetaMask wallet, display the token balance, and let me enter how many tokens to convert. • Allow me to define and later update the conversion price (token-to-ETH rate) from a simple settings panel so I can run private sales without touching the code. • Build and sign the transaction client-side via MetaMask, then broadcast it so the user receives ETH back to the same wallet once the swap succeeds. • Show clear status and Tx hash feedback while the transaction confirms. Please keep the script focuse...

I’m building a real-cash Ludo experience that runs just as well in a WebGL browser window as it does on Android. Players will stake and win USDT, so every deposit and payout must flow through a robust escrow smart contract. The contract should hold funds during the match, automatically release winnings, and connect to common Web3 wallets (MetaMask, Trust Wallet, etc.) for a friction-free on-ramp. Gameplay & rooms • Classic 4-player Ludo rules. • Public lobbies anyone can jump into plus invite-only private tables—users choose on the fly. • Live matchmaking, reconnection handling, and anti-cheat logic.

I need a solid ERC-20 smart contract that supports on-demand minting and follows best-practice security patterns (OpenZeppelin, upgradable proxies or other proven approaches you’re comfortable with). Alongside the contract, I want a lightweight web dApp that lets users connect with MetaMask, view total supply, and call the mint function in a single, smooth flow. A clean React or front end with is fine; if you prefer Vue or another modern stack, I’m open as long as the UX is clear and responsive. Key acceptance criteria: • Verified, optimised Solidity code deployed on Ethereum mainnet (testnet first for review). • Minting controlled by owner role, with events properly emitted. • Front-end fully wired to the contract, wallet-connect ready, and d...

...guaranteed allocations. A lightweight quest system will encourage users to complete tasks such as testnet participation, feedback submission, or community engagement. Basic anti-Sybil measures, including wallet verification and duplicate detection, should be included to prevent abuse. From a technical perspective, the MVP should include a frontend built in React or with wallet integration (MetaMask, WalletConnect), a backend using Node.js or Supabase to handle user scores, quests, and project data, and Solidity smart contracts to manage allocation logic and whitelist verification. An admin panel should allow project listings, configuration of token sale details, management of allocation tiers, and monitoring of user activity. A clean and intuitive UI/UX is important for both us...

...straightforward financial transactions, then wrap it in a clean single-page dApp so end-users can interact with it without touching the command line. The contract must be solidly coded in Solidity, thoroughly tested, and deployed to the mainnet once we finish our reviews. On the front-end I want a lightweight React (or similar) page that talks directly to the contract. Wallet integration is essential—MetaMask and any other common Web3 wallets should connect seamlessly so users can approve, send, and monitor transactions. A clear, searchable transaction history pane is the second must-have so people can verify their activity in real time. Beyond those core pieces I have several additional features in mind; I’ll share the full list and wireframes once we start and wo...

I need an EVM-compatible utility token deployed on Base for my upcoming gaming site. Players will log in with MetaMask, pay the platform in this new token, and—behind the scenes—my smart contract must swap the incoming tokens to USDC so merchants see funds settle automatically in stablecoins. The token’s first use-case will be rewarding players with bonuses and loyalty perks, but I’m open to more in-game utilities you can suggest. What matters most is a seamless, gas-efficient flow: • MetaMask connection on web front-end • ERC-20 (or optimized equivalent) minted on Base • Automated on-chain swap that routes each payment to USDC and transfers it to the merchant wallet in a single transaction • Clear documentation and a simp...

...functions (think DAO-style proposals for repairs, upgrades, management, etc.). • Enable seamless peer-to-peer ownership transfers, with automated updates to the cap-table and usage calendar. Front-end needs A clean, mobile-responsive dashboard where users can: – view token holdings, upcoming usage windows, and quorum-based proposals, – cast votes in real time, – list or accept transfers. MetaMask and WalletConnect support are mandatory; additional wallets are a plus. Back-end / contract layer Solidity contracts should be upgradable (OpenZeppelin proxies are fine) and thoroughly tested. I will require unit tests, basic audit documentation, and a short deployment guide for Ethereum mainnet plus at least one EVM side-chain (Polygon or similar) to k...

...will launch with Casino games only—specifically Slots, Blackjack, and Roulette—so please come prepared to handle random number generation, fairness proofs, and attractive front-end animations for all three. User accounts & security Registration must include Two-factor authentication (email/SMS or an authenticator app). Each account will have an on-site balance plus a connected crypto wallet (MetaMask and WalletConnect support to start). Users should be able to move funds freely between the wallet and their casino balance with clear transaction logs. Pool creation & voting Players can create wagering pools; others vote to join using on-chain signatures. Once a pool fills, the game launches automatically. I’ll provide detailed pool rules—you wi...

...for upgradability and security Front-end & integration The dApp should connect smoothly through MetaMask or WalletConnect, display pool metrics in real time, and guide users through providing liquidity, staking, claiming rewards, and withdrawing.

Acceptance criteria • All Solidity code compiles under the latest stable compiler, passes 90 %+ test coverage, and is formatted per Prettier-Solidity • Gas usage optimized and no high-risk findings in a basic MythX or Slither scan • Front-end loads in under 3 s, correctly reflects on-chain state, and works in Chrome/Brave + mobile MetaMask • Complete README with deployment scripts and inst...

I’m building a proof-of-concept for my university thesis: a decentralized authentication system based on blockchain. The goal is to implement a web application where users authenticate by signing a message with MetaMask, demonstrating a decentralized login mechanism using cryptographic signatures. Frontend • A lightweight interface (React preferred) that connects to MetaMask using • Prompt the user to sign a message • Display authentication result clearly (success / failure) Backend • Node.js service (Express preferred) • Generate a nonce or message to sign • Verify the signed message against the user’s public wallet address • Return JSON response indicating authentication result Integration & Code Quality • Clean a...

...off-chain. The flow I have in mind: 1. User opens the React front-end (MetaMask connected). 2. They drag-and-drop a certificate (PDF, image, or any common format). 3. The app calculates a SHA-256 hash, sends it to a Solidity contract, and the contract records it immutably on the blockchain (local Ganache during development, then a public testnet or mainnet). 4. To verify, another user re-uploads the certificate; the app re-hashes it and checks the smart contract for a match, instantly confirming authenticity. Technologies I expect you to use include Ethereum + Solidity for the contract layer, React/HTML-CSS-JS for the front-end, and either Node.js or Python for any necessary server-side helpers. MetaMask integration is essential so transactions originate from...

I’m ready to commission a Web3 solution that combines a fully-functional decentralised application with its underlying smart contracts on both Binance Smart Chain and Tron. Core scope The front-end should let users connect their wallets (MetaMask for BSC, TronLink for Tron), approve token spending, initiate transfers, and instantly view their own balances alongside any relevant contract balances. Everything has to feel seamless, with on-chain calls reflected in the UI in real time. Back-end expectations • Smart contracts written in Solidity for BSC and the Tron-compatible variant, compiled, audited for common vulnerabilities, and deployed to mainnet after a successful testnet round. • Clear functions for approve, transfer, and balanceOf, exposed for the d...

I need a lightweight crypto exchange that fits within my ₹3,000–5,000 budget. I am not chasing an enterprise-grade product—just a clean, working web app where a user can sign up, deposit to an in-built wallet, and place basic buy/sell orders. Core flow I must see working: 1. Secure sign-up / log-in (email + password or MetaMask) 2. Wallet generation or connection 3. Simple order form to buy and sell at the latest market price 4. Instant balance update and a short transaction history visible in the dashboard I am flexible on the tech stack, but a typical React + Node.js (or Laravel/PHP) back end tied to a public price API such as CoinGecko or Binance REST will keep costs low and development fast. If you already have a starter template or white-label script, fe...

I already have a draft smart contract, but it needs a careful review and a few modifications before going live. Once the code is solid, I want it deployed on Ethereum (that is my first choice, though I’m open to discussing BSC or Polygon if you feel they offer clear advantages). After deployment, the contract must be fully integrated into my website so users can interact with it through MetaMask. A smooth, reliable Web3 flow is essential—wallet connection, transaction signing, on-chain confirmations, and any UI feedback should feel seamless and secure. The job breaks down into three main parts: • Audit, adjust, and finalise the existing contract code, then compile, test, and verify it on the chosen network. • Deploy the verified contract and wire it up t...
