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...

I need a brand-new ERC-20 smart contract built from scratch, then deployed to the Ethereum network. The token must include minting, burning, and pausable functionality, implemented with clean, upgrade-friendly Solidity code that follows current best practices (OpenZeppelin libraries, Hardhat or Foundry for testing). Please create, test, and deploy the contract, then hand over everything required for future maintenance. Deliverables • Verified Solidity source code with mint, burn, and pause modules • Full test suite covering core logic and edge cases • Deployment scripts and step-by-step notes (addresses, gas used, etherscan verification) • Final token address on Ethereum mainnet or a clearly documented test deployment if mainnet is postponed Accep...

I am in the middle of financial-remedy proceedings and have been appointed to instruct a single joint expert. My ex-partner has disclosed a series of public keys and wallet addresses; however, I still need a clear, defensible picture of exactly how much cryptocurrency he currently holds and through how many wallets. The work centres on three core blockchains—Bitcoin, Ethereum and Ripple—but there may be additional tokens mixed in, so flexibility to widen the net is essential. I can supply every public key and wallet address already disclosed, and I can request anything else you identify as relevant. Your task is to trace those identifiers on-chain, calculate the present balances, and compile a concise report that can stand up to court scrutiny. Chain-analysis platform...

...Complete source code with clear installation/compilation instructions • Brief technical documentation outlining architecture, key-management method, and backup/restore logic • A short demo video or walkthrough proving send/receive, history display, and backup/restore work on mainnet or testnet Acceptance criteria • Wallet sends and receives transactions successfully on at least one EVM chain (Ethereum testnet is fine). • Transaction history populates within 10 sec of login on a typical 4G connection. • Backup restores the identical account and transaction list on a fresh install without data loss. • Code passes basic static analysis (no hard-coded private keys, secrets, or fatal vulnerabilities). Once these points are met, I’m rea...

...I do know is that the end product will rely on smart contracts, a dApp front end, and secure wallet interaction, so familiarity with Solidity or similar contract languages, , and modern front-end frameworks is essential. Here’s how I’d like to structure our collaboration: – First, a short technical workshop where you assess my concept, recommend an appropriate blockchain (Ethereum, BSC, Polkadot, or another you feel fits), outline the contract architecture, and flag any compliance or security considerations. – Once we lock the specs, you’ll build the smart contracts, write thorough unit and integration tests, and deploy to a testnet. – Finally, we’ll connect the contracts to a simple but polished front end, run a security review,...

I want to launch a simple USDT Stable Coin and I want it live on any of the three major networks: BEP20 (Binance Smart Chain), ERC20 (Ethereum), and TRC20 (Tron). The token only needs the core Tether behaviour—holders must be able to transfer tokens and see their main & asset balance with standard calls, original Logo. If you already have experience shipping tokens on any of these networks and can complete the third quickly, let me know—speed and reliability matter more than extra features.

I’m putting together a consumer-to-business payment gateway that runs entirely on Ethereum. The goal is for any online shop or SaaS platform to accept on-chain payments in ETH or ERC-20 tokens and receive instant confirmation through a simple API or Web3 hook, with built-in fraud checks before funds reach the merchant. Here’s the flow I have in mind: a shopper clicks “Pay with Crypto,” the gateway spins up a one-time smart-contract address, watches the chain for the deposit, runs fraud-detection logic (velocity limits, address reputation, basic AML heuristics), and then notifies the merchant’s backend via webhook or GraphQL subscription. Successful transactions should settle directly to the merchant’s wallet; failed or flagged payments must trigg...

I am building a service that must accept one-time customer payments directly on a public blockchain. My preferred rail is Ethereum, so the core of the job is a production-ready smart-contract–plus–API stack that lets me generate unique payment addresses, confirm the transfer, and surface the confirmation back to my app in real time. Here’s what I need the finished package to do: • Solidity smart contract deployed on Ethereum mainnet (initially Kovan/Goerli for testing) that logs each payment, enforces one-time use, and emits an event my backend can listen to. • Lightweight Web3 interface or RESTful webhook that notifies my server once a transaction reaches a configurable confirmation depth. • Simple front-end snippet (HTML/JS) that shows ...

...monitor USDT on Ethereum. The core of the job is to stand up a private Ethereum node (Geth, Erigon, or another production-grade client you recommend), then layer on the components below: • Wallet creation & management ‑ Generate unlimited ERC-20-compatible addresses locally. ‑ Store keys only on my server; nothing ever leaves it. ‑ Simple CLI or lightweight web panel is fine as long as it’s secure and documented. • Transaction tracking ‑ Real-time detection of incoming USDT transfers to any generated address. ‑ Callback or webhook that posts the transaction hash, amount, sender, and block confirmation count. ‑ Dashboard or log view so I can audit activity at a glance. No exchange or cross-chain connections are needed; everythi...

I need Google Analytics 4 to register every meaningful moment a visitor interacts with our Ethereum-based wallet integration. The scope covers: • Wallet connections – I want separate events when a user connects successfully and when the attempt fails. • Transaction completions – log both payment-success and payment-failed states. • General wallet errors – surface any other connectivity issues as a distinct event so they do not disappear inside generic JavaScript error noise. You may hook into the existing Web3 provider ( is already on the page) or propose an alternative, but the final data must enter GA4 cleanly, ideally through Google Tag Manager for easy maintenance. Acceptance criteria – GA4 real-time debug view shows the five...

...its engineers prefer. • Attack coverage baked into the dataset pipeline: the IDS must correctly classify Malware, Phishing, and DDoS patterns. Synthetic generation for edge cases is fine as long as the final validation shows clear detection rates for all three. • Smart-contract aggregator: the chain’s sole responsibility is aggregating model weights. I want a concise contract—Solidity for an Ethereum PoA test-network or chaincode for Hyperledger Fabric—that stores submissions, computes the federated average, and emits the new global state. No on-chain data other than floats and a small hash for versioning. • bridge: a lightweight Python client that listens for the latest global weights, injects them back into the local model, and kicks off the...

Digital Chain of Custody for Forensic Evidence ​Concept: A system for police and legal teams to track digital evidence (logs, hard drive images, CCTV footage) without ta...defense claims it was tampered with after seizure. ​The Solution: When evidence is collected, a cryptographic hash (SHA-256) of the file is generated and stored on a Blockchain. Every time the evidence is "checked out" or viewed by an officer, a transaction is recorded. If the file hash changes even by one bit, the Blockchain rejects it. ​Tech Stack: ​Frontend: React.js or Flutter. ​Blockchain: Ethereum (Sepolia Testnet) or Hyperledger Fabric (for private permissioned access). ​Storage: IPFS (InterPlanetary File System) to store the actual large files; Blockchain only stores the hash. ​Smart Contracts: S...

I’m building an e-commerce flow where every new order receives its own self-custody Ethereum deposit address. I need a small service that can: • Derive a fresh address from a master wallet (BIP-32/44 HD path preferred) each time my store’s API creates an order. • Secure those addresses behind multi-signature authentication so funds can only be moved with the required M-of-N signatures I specify. • Listen to the Ethereum blockchain in real time, detect incoming payments to any of the generated addresses, confirm once they reach my chosen block depth, and push a webhook or callback so my application can mark the order as paid. You’re free to use tools like , , or a light-client implementation in Node or Go; just keep everything non-custodi...

I need a unified workflow that collects my text documents, images, and videos, packages each bundle as on-chain metadata, and mints it as an NFT on Ethereum. The resulting token must permanently prove ownership, allow normal transfers, and embed a royalty mechanism. Alongside the minting process, I want a language model to process the same material—extract keywords, generate a concise summary, possibly produce embeddings—and write those insights back into the token’s metadata or a linked JSON file. Think Solidity (ERC-721 or ERC-1155 with OpenZeppelin), IPFS or Arweave for storage, plus a Python or Node script that calls GPT-4 / Llama via LangChain or similar. This person must also be familiar with setting up a blockchain and wallets. Specifically using AWS to st...

I’m upgrading my platform to process transactions through a dedicated blockchain gateway so every payment that passes through the system is cryptographically verifiable and tamper-proof. The job covers designing the gateway architecture, selecting an appropriate chain (Ethereum, Polygon, BSC or another you can justify), building or customising smart-contract code if that proves to be the simplest route, and exposing clean REST/JSON or Web3 interfaces my front-end can call. The core success metric is end-to-end security: a user initiates a payment on the site, the request reaches the gateway, the transaction is written on-chain, and I receive an instantly checkable hash I can surface back to the user. Performance must remain within normal web-app latency, and the code needs to...
