Liquidity Staking Token (LST): Users deposit ETH into the protocol and receive tokens that represent proof of liquidity. The protocol stakes the ETH into Ethereum to earn rewards distributed to the stakers. For example, users stake ETH into Lido and receive stETH.
Liquidity Re-staking Token (LRT): Users deposit ETH or LST into the protocol for re-staking and receive tokens that represent proof of re-staking. The protocol stakes the ETH or LST into EigenLayer to earn rewards distributed to the stakers. For example, users deposit stETH into KelpDAO.
