Liquid staked ETH (stETH) is not currently supported on Polygon due to the fact that Lido does not currently offer stETH or derivatives on Polygon. This means that users of Polygon are unable to stake their ETH and receive rewards in the form of stETH. However, if users have a specific vault in mind for staking their ETH, they can request it through Lido's "strategy devs" channel. This channel allows users to request specific vaults and provides the necessary support and guidance to make the process easier. While stETH is not currently supported on Polygon, users can still benefit from the staking rewards offered by other Ethereum Layer 2 networks.
