DEPOSITED - validator's deposit has been recognized by Ethereum 1, not yet recognized by Ethereum.
PENDING - validator is in Ethereum's activation queue.
ACTIVE - validator is active.
EXITING - validator has initiated an exit request, or has dropped below the ejection balance and is being kicked out.
