Alternative Key Management

Validator keystores don’t need to be stored locally — you may prefer to manage them externally for better security or flexibility.

This section covers three alternatives:

Remote Signer → – isolate signing operations from your Operator Service.

HashiCorp Vault → – integrate with enterprise-grade key management.

Relayer (API Mode) → – fully decouple key creation and storage from the Operator Service.

Dive into each section to learn how these options work and how to implement them in your setup.
