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

- Follows the [Web3Signer](https://consensys.github.io/web3signer/web3signer-eth2.html) specification
- Compatible with existing Consensus clients
- Designed to run on Intel SGX via the [Occlum LibOS](https://github.com/occlum/occlum)
- Provides protection from [slashable offenses](https://github.com/ethereum/consensus-specs/blob/master/specs/phase0/validator.md#how-to-avoid-slashing)

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](https://hub.docker.com/repository/docker/pufferfi/validator/general) for the latest enclave image.
