Good day!
I am a freelancer with experience in on-chain analysis in BTC, ETH, BNB Chain, Solana, and TRON networks. I work with tools such as Blockchair, OKLink, Etherscan, BscScan, Solscan, Arkham, Nansen, and other analytical platforms.
I am ready to perform:
a complete analysis of the transaction history for the provided addresses;
building transfer chains (sender → receiver → further movements);
detecting interactions with exchanges, DEX, bridges, smart contracts, launchpads;
collecting key statistics (volumes, frequency, types of operations, suspicious patterns);
preparing a structured and clear report (table + main conclusions).
The format of cooperation is project-based involvement.
My rate is 50 USD/hour.
I am ready to discuss the details of the first task and the deadlines for completion.

Hello. I am a very advanced user of various scanners for blockchain. In my main job (as a web3 programmer), I had tasks that required investigating wallets, transactions, and smart contracts to replicate the logic of certain scripts. I also have reverse engineering skills, which will perfectly complement the set of necessary skills for your tasks.

Good day. I am ready to complete this project as I have extensive experience in application development.

I have experience in on-chain analysis in BTC, ETH, Solana, and TRON networks. I use professional visualization tools (Arkham, Nansen) and custom scripts for data collection, which allows me to uncover hidden connections between wallets that are not visible in regular explorers.
I will prepare a structured report for you with a detailed transaction map, identification of addresses (CEX, DEX, Bridges), and analysis of anomalous activity. I guarantee clarity of conclusions without unnecessary fluff. I am ready to start working today. I can also offer to write a bot for automation of tracking.

Hello! I am ready to complete your tasks related to on-chain analysis. My advantage is automation: instead of manual searching, I use my own Python scripts (Etherscan API, Arkham), which guarantees the detection of 100% of transactions, including hidden ones (Internal).
What you will receive:
Accurate chains: I track the movement of funds through bridges, DEX, and mixers to the final withdrawal points.
Speed: Thanks to the code, I process data arrays several times faster than competitors.
Report: A clear table with wallet identification and patterns of suspicious activity.
Networks: BTC, ETH, BSC, SOL, TRON. I am ready to take the first case (1–10 addresses) into work today.
Best regards, Pavlo

Development of a Telegram Mini App (Bot + WebApp) for selling digital goods and in-game currencies (Python / aiogram) Project description: A Telegram bot with a full WebApp interface is required for the automated sale of digital goods (Telegram Stars, Telegram Premium, in-game currencies/donations for PUBG Mobile, Steam, etc.). The project is called Aspect App. The main focus is on speed, smooth UI/UX in a Web3/minimalist style, and complete automation of product delivery after payment. Technology stack: Backend: Python 3.10+, aiogram 3.x (FastAPI for Webhook/API is welcome). Database: PostgreSQL / Redis (for sessions and caching). Frontend (WebApp): React.js / Vue.js / Next.js (at the developer's discretion, speed and smoothness of animations are important). Integrations: Telegram WebApp API. Main functionality (MVP): 1. Client side (Telegram Mini App): Main screen: Product categories (Telegram Assets, In-game Donations). Banner grid for promotions. Product catalog: Product cards with volume selection (e.g., 50, 100, 500 Telegram Stars or UC). Fields for entering player data (Player ID for PUBG). Cart and Checkout: Quick purchase in 2 clicks. Payment module: Integration of payment methods (CryptoBot API / TON Connect / other fiat gateways by agreement). Personal account: Order history, status tracking, referral system (balance within the app). 2. Admin panel (built into WebApp or separate bot): Catalog management (adding/removing products, changing prices). Order monitoring and sales statistics. User database mailing system. 3. Automation logic (A plus): Readiness of the architecture for integration with supplier APIs (API for auto-purchasing Stars/UC). At the MVP stage, some products may be issued with codes from the database. What is required from the contractor: 1. Development of the database and backend architecture in Python. 2. Layout and integration of WebApp (design mockup to be discussed, clean Web3 style, Glassmorphism is important). 3. Setting up secure transactions and payment webhooks. 4. Deployment on the server (Docker, Ubuntu, SSL setup). Candidate requirements: Experience in commercial development of Telegram WebApps for at least 1 year. Portfolio with launched and working Mini Apps (please provide links in your response). Clean, documented code. Working conditions: Work only through the Secure Deal (Safe / Escrow) of the platform. Payment is staged (the project is divided into Sprint 1: Backend + DB, Sprint 2: Frontend WebApp, Sprint 3: Payment integration and testing). Budget: To be discussed with the successful candidate (please indicate your price range and timelines in your response)
