Intro

Pay Protocol adopts a decentralized smart contract protocol, dedicated to providing a non-custodial Web3 digital encryption asset payment gateway service.

Compared to traditional crypto asset custody and payment solutions, Pay Protocol has the following significant features:

  1. Fully Decentralized Service: Traditional solutions need to ensure server security and rely on professionals to maintain payment and custody servers. Pay Protocol leverages the advantages of blockchain technology to provide a 7x24 uninterrupted secure blockchain contract solution. Funds are decentralized, achieving cold and hot isolation, and multiple management permissions can be set to ensure safety and convenience.

  2. On-chain Confirmation for All Transactions: Pay Protocol's smart contract protocol records every transaction on the blockchain, significantly reducing GAS consumption through the log function, achieving full on-chain data recovery. Even in extreme cases where the Pay Protocol server is completely destroyed, it can guarantee the safety of merchants and users' funds and the complete recovery of order records.

  3. Secure Fault Traceback: Compared with traditional custody solutions, Pay Protocol avoids the funds first being transferred to a third-party platform's custody fund pool or being hosted by trusted nodes (such as the MPC private key fragmentation scheme), reducing dependence on third-party platforms. Pay Protocol is secured by the underlying blockchain, sharing the same security level with the public chain. All operation records can be queried and traced, effectively preventing improper internal behavior.

Pay Protocol is built by a team with many years of DeFi development experience, using assembly-level smart contract development language, which ensures security and greatly reduces network GAS costs. The protocol is open source and has been audited by multiple auditing companies. Adopting the mature solution of Pay Protocol can significantly reduce the risk of Web3 crypto asset payment and custody, reduce internal R&D costs and cycles. We provide a simple API interface, open source and editable front-end modules, and a powerful backend management system, let's create the future together.
