Secure-Signer

Secure-Signer

Secure-Signer is a remote signing tool for Ethereum PoS validators, with the following features:

• Follows the Web3Signer specification
• Compatible with existing Consensus clients
• Designed to run on Intel SGX via the Occlum LibOS
• Provides protection from slashable offenses

Validator keys are safeguarded in SGX's encrypted memory and the hardware enforces that Secure-Signer can only sign non-slashable messages. This reduces validator risk from slashing either from accidents or if their system is compromised.

SECURE SIGNER IS UNDER DEVELOPMENT, see DockerHub for the latest enclave image.
