What is Secure Self-Custody?​

Secure self-custody is a fully smart contract-based solution for managing crypto assets. This solution allows merchants to have complete control over all crypto assets and permissions within their system without relying on any third-party servers or services. At the same time, it ensures multi-node security, preventing the loss of funds or data due to the compromise of a single point of authority.

When evaluating whether a solution meets the standard of secure self-custody, two key considerations must be addressed:

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 UtcPay, 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 UtcPay 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.

According to the operating mode of UtcPay, the funds paid or recharged by customers will be stored in the merchant's sub-contract. Merchants can extract the funds to their own wallets through the "Sweep"-"Rebalance"-"Transfer" process.

For ease of expression, this article uses "hot wallet" to refer to the hot contract address of the Pro version.

PRO and STD merchants use a contract with multi-signature functionality to manage members, merchant configurations, and transfer operations. This article will explain how to use the multi-signature contract to manage your organization and funds.
