Payments are a crucial scenario in the cryptocurrency ecosystem, with tens of thousands of cryptocurrency payments occurring both on-chain and off-chain every day. A new cryptocurrency often appreciates in value due to its practical use in payments, making payments an essential bridge connecting the Web2 and Web3 worlds. In recent years, traditional payment providers have been actively entering the Web3 payment space, launching products such as stablecoins and peer-to-peer transaction infrastructures. The driving forces behind this trend include the high profit potential of the cryptocurrency industry, intense competition and high operational costs in traditional payment businesses, and the payment advantages brought by new technologies. As more countries begin to regulate and legalize cryptocurrency payments, the prevalence of crypto payments will further increase. The development of blockchain technology and applications will further enhance the convenience, efficiency, and security of Web3 payment services
