LSaaS GuideETH LSDEjector

Ejector service plays an important role in ETH LSD stack. Every validator should run an ejector service to properly handle the validator exiting process, as users are free to unstake and withdraw.

⚠️When use our SSV client service to run validators, you don’t need to run an ejector service explicitly, cause it is embedded in the SSV client service.
