Web3 payments refer to a type of online payment that uses blockchain technology and decentralized finance (DeFi) to facilitate secure and transparent transactions. Unlike traditional online payment systems, which are often centralized and controlled by a single entity, Web3 payments are decentralized and allow users to make transactions directly with one another without the need for a trusted third party. Web3 payments are a key component of the growing Web3 ecosystem, which is focused on using blockchain technology to enable decentralized, peer-to-peer applications and services.
