A Trusted Execution Environment (TEE) is a secure hardware enclave that provides:
  • Isolated, encrypted execution of sensitive code
  • Cryptographic attestation of software integrity
  • Hardware-backed security guarantees
Arkade uses TEEs for:
  • Arkade Signer: Protects signing keys from operator access
  • Remote attestation: Proves only authorized code is running
  • Encrypted communication: Enables private user-signer interaction
TEEs transform the “trust the operator” assumption into “verify the operator”.
