Budget: 27000 UAH Deadline: 18 days
Hello, Bohdan 👋
My name is Semen, I am a Python developer with experience in creating Telegram bots for crypto projects, automating payment systems, transaction logic, and integrations with APIs (including Google Sheets, BTC services, Telegram Bot API, etc.). Your technical task looks very well thought out, detailed, and quite realistic to implement ✅
🔧 What I propose:
Based on your technical specifications, I can create a Telegram bot for a crypto guarantee service with the following functionality:
🔁 Main functionality:
Complete deal logic: creation, control, confirmation by both parties
Role distribution (client / executor / guarantor)
Generation and verification of BTC addresses from a pool
Real-time monitoring of address balances 🧮
Automatic payments considering a 3% fee
Logging transaction hashes and saving to files + Google Sheets
🛡️ Protection and stability:
Protection against spam and flooding
Validation of BTC addresses
Tracking participants leaving the chat and inactivity
Restoring the state of deals after a restart
Notifications + buttons to contact administrators
Converter $ → BTC with rate updates
💬 Mass support:
Processing dozens of simultaneous deal chats (from a text file)
Structured saving of deal statuses
Convenient scaling
🧩 Technologies:
Language: Python 3.10+ (for running through IDLE)
Libraries: aiogram / pyTelegramBotAPI, requests, gspread, python-bitcoinrpc or similar
Storage: JSON files or SQLite (if desired)
Integrations: Google Sheets API, BTC rates via API (e.g., CoinGecko / Blockchain.info)
💰 Estimated implementation cost:
from $1100 to $1600, depending on the depth of logic, number of user scenarios, and complexity of API integrations.
I will be able to provide the exact amount after clarifying a few nuances (for example, how BTC addresses are formed, whether there is a pool of addresses, or if they need to be created through an external service).
🕒 Deadlines:
≈ 12–18 days considering testing, debugging, and creating technical documentation.
📎 What is included in the collaboration:
Transparent and phased project management
Technical support for 14 days after delivery
Documentation + video instructions for launch
Reporting in a convenient format (Telegram / Trello / Google Sheets)
I would be happy to participate in the implementation of such an interesting project! If there is a technical specification in PDF/Word — I can study it right away. We can start with a short call or correspondence to clarify the details ☕
Best regards, Semen! | Telegram Bot & Python Developer
