Hello! My partner (designer + full-stack) and I have been specializing in the development and stabilization of trading bots for cryptocurrency exchanges for over 4 years, so we will help you turn "crooked" code into a reliable tool that does not crash and clearly executes strategies through the Bybit and Polygon APIs. We will conduct a deep refactoring of your current codebase, eliminate memory leaks (which cause it to crash), and implement an error handling system (Retry logic) so that the bot maintains a stable connection with the exchanges 24/7. Our experience in development is 4 years; take a look at our work from the perspective of technical logic and speed: hyperfi.tech, espressolab.com.ua, hudi.com.ua. We will integrate several trading strategies, set up connections to free AI models (via OpenRouter or Groq) for dynamic parameter adjustment depending on the market, and ensure transparent logging of each transaction. We will discuss the fixed cost after a quick audit of your code.

Good day! My colleague and I have been professionally engaged in technical automation and algorithmic trading for over 4 years, so we will help you get a "working bot" that does not lag and clearly executes commands via API. We will implement the bot's architecture in Python (Asyncio) for instant reaction to price changes, set up secure key storage, and implement a modular strategy system that can be easily expanded. Our 4 years of experience is confirmed by projects drkukharevich.rivne.ua, crave-agency.com.ua, jk-solution.com.ua, where we have already successfully "lifted" and stabilized problematic AI scripts. We will provide AI integration for trend analysis, set up automatic trading notifications in Telegram, and guarantee that the bot will operate without crashes even with unstable API responses. We work for results and are ready to discuss all the details of your strategy.

Good day, I am currently implementing a similar system and have a lot of developments. I am ready to assist with the implementation. There is currently a ready pipeline - multi-source price (Binance/Coinbase/Kraken/Pyth), integration with Polymarket CLOB API, a signal system with several strategies for any markets - crypto, sports, geopolitics, elections, companies. Dry-run simulator, circuit breaker, Telegram alerts. Python/FastAPI, Docker.

We will do it, you provide the strategies/trading stories and I will provide the working bot.
Write.
Budget: 150 USD Deadline: 3 days
Good day, I am a Python developer with extensive experience in developing Telegram bots of various complexity. I can complete your order quickly and efficiently. Write to discuss the details, I am ready to start today. I will also upload your bot to the server for stable operation 24/7 and I will provide technical support for the bot for another month. This is included in the cost.

I can access your current bot, quickly understand why it is crashing, and then proceed based on the situation: if there is really something to save, I will fix it and bring it to stable operation; if the code is completely dead, I will rebuild it properly on clean logic. This option is the most reasonable: first an audit, then either we fix it, or we don't waste time and create a working version.

What needs to be done: conduct an independent expert consultation on the implementation of multisig wallets to protect the company's treasury funds, which operates with high-volume payment processing in USDT across three networks - TRON (TRC20), BNB Smart Chain (BEP20), and Ethereum (ERC20). Requirements: (1) review available market solutions and recommend the optimal one for our profile - a single custodial platform for all three networks or a combination of separate tools for EVM and TRON; (2) propose a signature architecture (e.g., 2-of-3), key distribution among roles, thresholds for quick/large payments; (3) provide recommendations for key storage (hardware wallets, HSM) and procedures in case of key loss or compromise. For whom: the team administering the company's treasury with a high volume of crypto transactions. Success criterion: a ready recommended architecture with a clear implementation plan. Requirements: practical experience in implementing multisig, specifically with TRON (not just EVM), experience with specific solutions (Safe/Gnosis, Fireblocks, BitGo, Cobo, or native TRON multisig), preferably with cases of previous implementations.
