The staking process is triggered after a predetermined period of time or once a balance limit is reached.
At that point, the minter contract is paused to prevent any losses while creating the validators. SharedStake deploys multiple validators to the Eth2.0 Deposit Contract. After this process, the Minter Contract is unpaused and continues to accept Eth and mint vEth2 again.
The Minter Contract can be updated with SIPs and voted on by DAO members with SGT.
