The numValidators parameter is used by the minter to restrict the maximum number of validators that can be created and thus the maximum ETH deposits we will accept at the given moment.
This parameter has been deployed as 10,000.
This corresponds to a maximum deposit threshold of 320,000 ETH. (Recall 32 ETH per validator)
We want to do a guarded launch like in version 1, but leave it to the community to pick an appropriate number.
You can see the current params at the contract here: https://etherscan.io/address/0x85Bc06f4e3439d41f610a440Ba0FbE333736B310#readContract or via the stake gauge on the stake page in the sharedstake.org UI
Once governance picks a number, SGT Multisig will call setNumValidators(uint num) on the minter at 0x85Bc06f4e3439d41f610a440Ba0FbE333736B310
