# Trusted Execution Environments FOGEVM utilizes hardware-based isolation to ensure code integrity. We currently support Intel SGX and are expanding to AWS Nitro Enclaves. #### The "Black Box" Guarantee * **Remote Attestation:** Before a user submits a transaction, their wallet performs a cryptographic handshake with the node. The node proves it is running genuine, unmodified FOGEVM code inside a secure enclave. * **Memory Encryption:** Even if the cloud provider dumps the RAM of the physical server, the data belonging to FOGEVM remains encrypted. --- # 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.
