Browser Interceptor

Definition ∞ A browser interceptor is a software component, often a browser extension, designed to monitor and modify network requests originating from a web browser. In the context of digital assets, these tools frequently interact with decentralized applications or smart contracts, facilitating user interactions with blockchain protocols. They act as a conduit, translating user actions within a web interface into blockchain-compatible operations.
Context ∞ Browser interceptors are central to the user experience of many Web3 applications, particularly those involving cryptocurrency wallets and decentralized finance platforms. Their security and functionality directly impact user safety and the reliability of interactions with smart contracts. Concerns frequently arise regarding the potential for malicious interceptors to phish user credentials or reroute transactions.
