📄️ Remote Signer
You may not want the operator service to have direct access to the validator keys. Validator keystores do not need to be present directly in the operator. The operator can query a remote signer to get signatures for validator deposit and exit messages.
📄️ HashiCorp Vault
Operator supports loading signing keys from remote HashiCorp Vault ↗ instance, avoiding storage of keystores on the filesystem. This approach is best suited for node operators who already have most of StakeWise Operator functionality implemented in their systems, and only need integration for validator registration or pooling support.
📄️ Relayer (API Mode)
The Operator API facilitates the initiation of validator registrations via API calls, proving particularly useful in cases where the operator independently oversees the creation and storage of validator keys.
