Renzo Protocol simplifies Ethereum and Solana restaking. It uses smart contracts and operator nodes to manage optimal restaking strategies, maximizing user returns while minimizing risk. Users deposit ETH or equivalent tokens to receive Renzo's liquid restaking tokens (LRTs), like ezETH, which accrue rewards reflected in their price. This simplifies the complex process of interacting with various restaking protocols like EigenLayer, Symbiotic, and Jito Network.
