Smarte kontrakter Jobs

I need a clean, well-commented Solana Program written in Rust with Anchor that lets me create and manage a new token from scratch. The core requirement is straightforward token generation, but all critical actions—minting additional supply later, burning, updating metadata, pausing transfers—must be limited to an on-chain Administrator role defined in the program. Please structure the code so it compiles and deploys in Solana Playground with a single `anchor build && anchor deploy`, and include a short test or demo script showing the admin wallet exercising its exclusive privileges. A concise README that walks through setup, deployment, and typical admin calls will be the final piece I need to ship this into production.

I’m building a Windows-based game and I need a seasoned Solana smart-contract developer to handle two critical tasks at once: create a robust contract that powers our in-game economy and fine-tune every transaction so players never feel the blockchain running underneath. Here’s what I’m after: • Contract scope – In-game purchases – Player rewards (daily quests, achievements, seasonal drops) – Secure peer-to-peer item trading • Optimisation focus – Slash gas-like fees on Solana to the minimum practical level – Make transactions confirm fast enough that UI waits feel invisible – Keep performance consistent even when the network is congested You’ll plug the contract into our existing Windows clie...

I run a cryptocurrency NFT company in Southern California and need a team of Solidity engineers to build the backbone of our on-chain ecosystem on Ethereum. We believe that all companies will eventually launch their own loyalty and utility tokens, we are looking for developers that can help create and manage tokens for companies. The contract will combine three core capabilities: • Token creation and management – an ERC-20 (or comparable standard) that lets us mint, burn, pause, and allocate tokens for rewards, liquidity, and governance. • NFT minting and trading – ERC-721/1155 support with gas-efficient batch minting, on-chain royalties, and signature-based whitelisting for presales. • Decentralized marketplace – in-contract fixed-price and auction l...

We’re looking for experienced senior developer to join our team and help bring InnovaRise to life – a premium NFT project that blends Bitcoin history with video-based NFTs. We have already created MVP of our product and you will build first version of our product based on this MVP. What We Need Help With: • Customize NFT Marketplace Interface: Create a sleek, user-friendly marketplace from our MVP based on Figma Design. • Wallet Integration: Connect MetaMask, WalletConnect, etc. • Ethereum Smart Contract: Write and deploy an ERC-721A (or similar) contract with custom logic. • Mint-to-Render Connection: Trigger our existing video rendering pipeline once a token is purchased (this system is already built; just needs to be connected). • Backend: We will u...

Our playable browser-based game is live, yet the prototype code still feels like a prototype. I now want to move it toward a production-ready architecture while layering in genuine Ethereum functionality. The core objective is performance optimisation: render speed, state updates, and chain interactions must all feel instant to the player. That means refactoring React components with cleaner patterns, trimming bundle size, and tightening any Node.js endpoints that feed the client. Both the front-end/UI and the small Node backend will be profiled and tuned, and we’ll also benchmark every call that touches the EVM to be sure gas costs and response times are sensible. You’ll be working in a modern stack—React + Vite on the front end, a lightweight Express service on the ba...

I’m finishing up a real-time Web3 game and need an experienced blockchain engineer to slot into our tiny, fast-moving team. The core engine—rendering, networking, and game logic—is already in place; what’s missing is the on-chain layer that turns it into a true metaverse experience. Here’s what the role looks like day to day: you’ll design, code, and test smart contracts, hook them into our existing Python back-end, and expose everything to the front-end so players can transact seamlessly. Whether we deploy on Ethereum, Binance Smart Chain, Polygon, or a mix is still open for discussion, so your insight on trade-offs, gas optimisation, and security will heavily influence the final architecture. Because the feature list ranges from NFT minting and tradi...

I’m developing a hybrid exchange that combines a conventional CEX backend and front end with on-chain DEX modules running on Binance Smart Chain, and I need a highly experienced developer to create a newly developed CEX that could integrated with Binance Smart Chain ( API) and all functionality. More Importantly, the CEX could link to well over 100 tokens currently trading at Binance or other well-Known CEX exchanges. In addition, I am currently developing many individual DEX's that could be easily integrated to the CEX I am developing. It is called the hybrid functionality. Your focus will be threefold: • Smart contracts development: Develope Up to 10 smart contracts with different ticker symbols, fully registered, ready to do the ICOs, selling of tokens, providing liqu...

I’m ready to introduce a new utility token on the Solana blockchain and need an experienced developer to handle the technical build-out and launch. The token must support native staking and an automated rewards-distribution mechanism; no governance or voting logic is required. Deliverables • SPL smart contract code implementing the token, staking pool, and rewards distribution • Unit tests and a short walkthrough showing how staking and rewards are calculated • Deployment to Solana devnet for demonstration, followed by mainnet launch once approved • Clear, commented source code and a brief developer-level README I will provide the token name, symbol, total supply, and reward parameters as soon as we start.

I want every coin a player earns in my game to live on the blockchain so balances are transparent, tamper-proof, and easy to audit. The chain will power only the in-game currency: no item ownership, no trading, just rewards that are automatically credited after gameplay events. Your task is to create and deploy a lightweight, low-fee smart contract, then hook it into the existing backend so the game can call a simple awardCoins(playerId, amount) function from Unity. My priorities are security, minimal gas costs, and fast confirmation times, so feel free to suggest the most suitable network (Polygon, BSC, an L2 on Ethereum, etc.) and the right stack—Solidity, Hardhat, , Web3 for Unity—whatever gets the job done cleanly. Deliverables • Smart contract on a public testnet wi...

I have an ERC-20 / SPL token that already lives on Ethereum, Solana and Binance Smart Chain. The pieces that are missing are the contracts, relayer logic and front-end that let holders move the asset seamlessly between these networks. The core requirement is true cross-chain transfer—no swaps, no dApp interoperability extras for now—just the ability to lock or burn the token on one chain and mint or release it on the destination chain with full proof verification. The existing token contracts are live and verified on each network, so your focus will be the bridge layer itself. This includes: • On-chain contracts (Solidity for Ethereum & BSC, Rust/Anchor for Solana) • A lightweight relayer or oracle component to pass finalized block headers / proofs • Se...

I’m building “Tees That Talk,” a premium T-shirt brand that lets each buyer mint or claim an NFT as part of the purchase flow. The core stack is Solidity (ERC-721/1155), Thirdweb (React / ), Wallet Connect, and the Shopify storefront API. I already have the brand assets and basic Shopify theme; what I’m missing is an engineer who has actually shipped production-grade NFT contracts and can wire everything together end-to-end. From my own discovery work, NFT metadata management is likely to be our trickiest hurdle, so deep experience pinning images and JSON to IPFS or Arweave, handling provenance, and keeping metadata immutable after mint is essential. In parallel, I need clean, audited smart contracts, seamless wallet flows, and a checkout that feels native inside S...

Our problem: Access to funds for new projects Possible solution: Issuance of an ERC-1400 token 1. Consultation 2. Turnkey solution I need a Solidity-written smart contract that behaves exactly like a standard ERC-1400 token yet satisfies the extra demands of a fully fledged security token on Ethereum. Beyond the usual balanceOf, transfer, approve, and allowance logic, the contract must: • Distribute dividends proportionally to holders, with a simple function I can call to deposit ETH (or any ERC-1400 stable coin) and have payouts calculated and claimable. Gas-efficient bookkeeping is important. • Enforce compliance: transfers are allowed only between addresses that have passed an off-chain KYC/AML check and been added to a whitelist. I should be able to update that whitelist ...

I need an experienced blockchain developer to plug NFT functionality directly into my website. The smart contract is ready on the mainnet; what’s missing is the front-end and back-end bridge that lets visitors interact with those tokens without ever leaving the site. Your job is to wire my existing smart contract to the site, surface the token data in a clean UI, and make sure every on-chain call runs smoothly and securely. You are free to pick the most suitable stack—, , React, , or any equivalent—as long as the end result is fast, responsive, and easy for non-technical users to navigate. Acceptance criteria • Users can connect a wallet (MetaMask, WalletConnect, or similar) and see the correct wallet address reflected on the page • The site fetches and di...
