Hello.
I develop Telegram bots in NodeJS. Ready to start. Write me, let's discuss.
Goal: Create a Telegram bot that allows users to make payments in cryptocurrency, specifically in USDT on the TRC-20 network, automatically verify the payment, and after successful payment, send a form for completion and necessary text. The received funds should be automatically transferred to the main wallet.
What needs to be done?
1. Wallet Generation:
2. Automatic Payment Verification:
3. Response to User after Payment:
4. Automatic Fund Transfer:
5. Security:
6. Payment Tariffs:
7. Product and Tariff Descriptions:

Good day. I mainly do this kind of work so I can do it. Write to me, let's talk.

Good day, I have experience processing payments in TRC20. I already have experience developing similar systems, I can show them to you and explain how they are done and why. I will also immediately say that there are nuances that you are not considering right now, but since my rate is public, I cannot write them here due to competition.
Interacting with the blockchain, sending transactions, and not only with USDT but also with any other tokens is absolutely not a problem. If the withdrawals do not need to be instantaneous, I can even tell you about options for very cheap sending in the Tron network.
I also work with many other blockchains and can integrate other payment options.

Hello, I develop Telegram bots in Python (Aiogram3, aiogram_dialogs) for more than 3 years.
The possibility of interacting with trc-20 can be implemented using tronpy. I am ready to implement your bot and install it on the server.
Write, let's discuss the details.

Добрый вечер. А какой кошелек будет использоваться для USDT? Биржевой не подойдет, у них там с генерацией новых адресов будут проблемы

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.
