This article introduces the working principle, security design, and operational flow of the Pay Protocol Signer, aiming to help merchants understand how to achieve high-security on-chain asset management through an "offline signing + on-chain broadcasting separation" model.
When you make on-chain payments, wallets like TP (TokenPocket) and imToken may display a warning: "The address you entered is a contract address. Please verify before transferring." This warning often causes concern. Below is a detailed explanation.
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 document outlines a comprehensive security validation process, covering transaction operations, signature verification, payment flow, and the enhancement of service security and stability, with the goal of ensuring the security of transactions and the high availability of the system.
The Guardian (also known as a "Guardian") is a security service component deployed in the backend or on an independent server. It is used to perform secondary validation and permission review for on-chain transfer requests or other critical multi-signature operations originating from the merchant system.
Its core mechanism is:
After the merchant system completes the initial signature, the Guardian independently generates a signature using the same parameters and compares it with the original signature. Only when the content matches and the permissions are valid is the on-chain execution allowed.
This mechanism effectively prevents data tampering, forged signatures, and unauthorized operations.
This tutorial will guide you on how to repair orders where users have overpaid or underpaid through the backend management system.
Before starting to repair orders, please ensure you have the following information:
In the past decade, decentralized payments typically used EOA (Externally Owned Accounts) wallet solutions, including existing MPC solutions based on EOA wallet sharding. However, achieving fully decentralized payments without any custodial servers requires an all-contract solution for fund custody. The optimization of gas costs in full-contract solutions has been a core challenge for developers.
While full-contract solutions offer high security, optimizing their gas costs remains a core challenge for developers. This article will explore how to significantly reduce gas costs and promote the application of sub-contracts in real scenarios through contract factory template design and tight packing inline assembly solutions.
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 feature is only available for standard merchants.
The example addresses and accounts in the tutorial are for reference only. Please use your contract address and owner address for actual operations.
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:
