# Selective Disclosure FOGEVM implements a dual-key architecture inspired by enterprise compliance requirements. This separates **Control** from **Visibility**. * **Spending Key:** Used to sign transactions and move funds. This is never shared. * **Viewing Key:** A read-only key that decrypts the transaction history of a specific address. * **Use Case:** A company operating on FOGEVM can provide their Viewing Key to an auditing firm or a tax agency. The auditor can verify all flows and solvency without the data being public to competitors on the blockchain. --- # 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.
