Decentralized Application Interface

A decentralized application interface is the front-end layer that allows users to interact with smart contracts on a blockchain. It serves as the bridge between the complex, back-end blockchain logic and the user, providing a graphical environment to monitor market data, view order books, and manage portfolio positions.

The interface is designed to translate user inputs into valid blockchain transactions, which are then passed to the wallet for signing. Because these applications are decentralized, the interface itself does not hold the user's funds; it merely facilitates the communication between the user's wallet and the protocol's smart contracts.

This design allows for a trustless trading experience where the user maintains control throughout the entire lifecycle of a trade. It is the primary venue for price discovery and execution in decentralized financial markets.
