# vBTC Protocol vBTC is built on the BNB Chain using the BEP-20 token standard to ensure high compatibility with the existing DeFi ecosystem. The selection of BNB Chain as the initial network enables vBTC to leverage advantages such as low transaction fees, fast processing speeds, and a stable operational environment—well-suited for the widespread usage demands of the digital asset community. In the long-term roadmap, vBTC is designed with multichain expansion capabilities, aiming to enhance interoperability, extend DeFi applications, and reach a broader user base across various blockchain ecosystems. This expansion will follow a structured and carefully planned roadmap to ensure protocol-wide consistency and technical stability. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
