pzETH is the Liquid Restaking Token (LRT) issued by Renzo Protocol, representing user deposits of ETH or Ethereum-based liquid staking tokens restaked within the Symbiotic ecosystem. It allows holders to earn both staking and restaking rewards through an auto-compounding mechanism while maintaining liquidity for use in DeFi protocols. Users can mint pzETH by depositing ETH, stETH, wstETH, or wETH and can redeem it for the underlying assets.
