# 1 Introduction EtheLock is the physical layer for the Ethereum network. It bridges the gap between the absolute security of cold storage and the high-speed utility of hot wallets. We replace the anxiety of seed phrases with the certainty of physics. Your digital wealth is unlocked only by the cards you already hold. #### The Core Concept Traditional crypto security relies entirely on software. Software can be exploited, clipped, and silently accessed. EtheLock adds a **physical requirement** to every interaction. * **No Card?** No Access. * **No PIN?** No Access. * **Both Combined?** Total Control. #### Why EtheLock? * **No Seed Phrases:** Your wallet is deterministically derived from your physical card + PIN. You are the recovery key. * **Ephemeral Keys:** Private keys are generated on-demand for the session and destroyed immediately after. Nothing is stored on disk. * **Global Spending:** Instantly spin up virtual Visa cards funded by your ETH. * **Zero-Knowledge:** Prove ownership and compliance without revealing your identity. --- # 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.
