Bot-guarantee for the flea market

Hello 👋
I am ready to implement a reliable Telegram bot for "Safe Deal" in your chat.

My technical solution:
Backend: Python (aiogram) and PostgreSQL. It will ensure stability and reliable operation of deal statuses (Pending -> Hold -> Success -> Dispute).
Architecture: I will build the correct logic for holding funds and develop a convenient arbitration panel for fair dispute resolution.
Security: I will implement reliable protection against scammers in the chat and prevent the forgery of payment confirmations.
I specialize in developing complex Telegram bots with financial logic, so I will create a product that truly protects your users and will not break under load.

… Message me privately to discuss Telegram Payments. I respond quickly!

I will develop a Telegram bot in Python (aiogram) for secure transactions on a marketplace. I will implement a system for holding funds until confirmation from both parties, as well as features for refunds and disputes, using Telegram Payments. This will significantly reduce the risk of fraud.
Contact me, we will discuss everything in detail, and I can start working immediately.

I will create a Telegram bot with guarantor functions: accepting payments through Telegram Payments (only for delivery), holding funds until the transaction is completed, transferring after confirmation from both parties, the possibility of refunds/disputes. I have experience in Python and Telegram API.

Hello! I can implement this functionality. I have experience in developing Telegram bots in Python and working with PostgreSQL, which is critical for reliable storage of transaction states and payment history.

Here is how I see the implementation:

- Payments: integration through Telegram Payments (connecting LiqPay/Stripe or another acquirer).

- Escrow logic: creating a system for holding funds on the payment system side or logic for transferring after confirmation by both parties (2-way handshake).

- Dispute system: developing a mechanism for refunds or involving a moderator in case of disputes.
…
- Security: protection against manipulation of order statuses in the database.

For the final calculation of timelines and costs, I need to clarify:

- What is the expected load on the service (number of active transactions simultaneously)?

- Which payment provider is planned to be used?

- How deep should the "disputes" logic be (is a separate interface for arbitration needed)?

I am ready to discuss the details. Write to me.

Hello
And how do you plan to pay the other party? This API does not provide such an opportunity.

Hello!
The topic of security in marketplaces is close to me. The task is clear: you need a classic Escrow service (holding funds), which acts as an intermediary between the buyer and the seller, protecting both from scams.
I specialize in developing complex bots in Python (using the Aiogram library) and am ready to implement secure transaction logic.
The technical solution I propose:
FSM (Finite State Machine) logic:
I will implement a strict sequence of transaction states: Create request -> Hold funds (Pre-checkout query) -> Confirm receipt -> Payout/Refund. This will eliminate situations where money gets stuck or disappears.
Payment system:
I will integrate the Telegram Payments API (through providers like Smart Glocal or Stripe, depending on your legal entity/region) for freezing funds for delivery.
Database (PostgreSQL/SQLite):
… All transactions, user IDs, and payment statuses will be securely stored. In case of a dispute, the administrator will have a complete history of actions (who pressed the button and when).
Dispute system (Arbitration):
A "Open dispute" button that calls the admin to the transaction chat or forwards logs for manual resolution.

Hello! I studied the task. Creating a bot that will defeat scammers and take care of the delivery payment is feasible. Here are the main problems we see and how we will address them:

1. Problem: Scammers take advance payments and disappear.

Our solution: The money for delivery does not go immediately to the seller's card. It is "frozen" within the system. The seller will see it, but can only withdraw it when you confirm receipt of the package.

2. Problem: Security and trust.

Our solution: We will connect official payments through Telegram. The buyer does not need to send money to suspicious cards — payment goes through a secure window (like in an online store).
…
3. Problem: Conflicts ("I sent it," "But I didn't receive it").

Our solution: The bot will have a "double confirmation" system. The deal will close only when both parties press the buttons. If something goes wrong, there will be a "Dispute" button — then an administrator will get involved in the situation.

How we will do this (step by step):

Database setup: We will create a reliable storage for all transactions so that no payment is lost.

Payment system integration: We will set up an official payment gateway in Telegram.

Protection logic: We will write an algorithm: Payment → Freezing money → Confirmation → Payout to the seller or Refund.

Testing: We will check all scenarios, including refunds and payment errors, to ensure the bot works like clockwork.

I am ready to discuss the details and start the first stage.
