Staking on Ether 2.0 has already surpassed the total quantity of "wrapped Ethereum" on the network, reaching 6.73 million ETH (about $21.2 billion). Staked, or tokenized, versions of the Ethereum network will be able to be used straight away when it merges with the proof-of-stake chain. The merge is expected to happen sometime early in 2022; there are currently 6.69 million on the network.
