A user's sub-contract can sometimes be contaminated by malicious transfers (e.g., receiving blacklisted USDT). If a normal sweep is performed, the blacklisted funds would be transferred into the cold contract, putting the merchant's main funds at risk. To prevent this, merchants should first blacklist the contaminated sub-contract to exclude it from the normal sweep flow, then use the emergency sweep feature to sweep the funds to a safe external address instead of the cold contract, achieving risk isolation.

The steps to use the emergency sweep feature are as follows:

1. Overview​

Tag Address is used to categorize and manage wallet addresses. When creating a payment order, merchants can specify tagId so the system automatically assigns a receiving address from the corresponding tagged address pool.

Address allocation rules:

• If an available address exists under the tag, the system prioritizes reusing it.
• If all addresses under the tag are occupied, the system automatically creates a new address.
• The newly created address is automatically assigned to the same tag.

This mechanism helps merchants achieve:

• Address categorization
• Address reuse
• Automatic address expansion

This mechanism is ideal for merchant scenarios that require managing a large number of receiving addresses.

Documentation Overview​

This guide helps merchant administrators complete the following configurations:

• Enable new blockchain networks (such as ETH, BSC)
• Add new cryptocurrencies (Tokens) on the blockchain

To help merchants further reduce energy costs, we have added support for the ITRX platform. Merchants can now choose to automatically purchase energy from ITRX or Neee before on-chain operations, thereby reducing TRX consumption.

This tutorial will guide you on how to repair orders where users have overpaid or underpaid through the backend management system.

Prerequisites​

Before starting to repair orders, please ensure you have the following information:

1. Order Number: The order number or payment number that needs to be repaired.
2. Transaction Hash: The transaction hash of the user's payment (can be obtained through a blockchain explorer or payment platform).

This tutorial will guide you on how to buy energy through the TG mini program to reduce transaction fees when performing functions such as sweeping and rebalancing on the Tron network.

This tutorial will guide you on how to replace the batch transfer contract address and display the balance information of the address in the admin console. After the replacement, any administrator can perform the transfer-in operation, while only the owner of the batch transfer contract has the authority to perform the transfer-out operation.

To help merchants reduce network fees, we have introduced the TRON automatic energy purchase feature. With the help of a third-party platform, merchants can automatically purchase energy before performing on-chain operations, thereby reducing TRX consumption.

If you need to use this feature, please follow the steps below:

When customers make payments using Pay Protocol, merchants may encounter issues such as payment failure, overpayment, wrong address, or wrong currency. Merchants need to handle these issues based on the information provided by the customers.

TRON is a decentralized platform based on blockchain, aimed at establishing a global free content entertainment system. In the TRON network, bandwidth and energy are two important resources that are crucial for executing transactions and smart contracts.

The operation of Pay Protocol is based on smart contracts, and each operation by merchants requires a certain amount of bandwidth and energy. This article will introduce the concepts of bandwidth and energy, as well as how to save on network fees by purchasing energy on the TRON network.
