'Lido for Solana' is a liquid staking protocol that enables Solana token holders to get liquidity on their staked assets. Through Lido, staked SOL becomes liquid and can be traded or used as collateral in DeFi products. SOL token holders deposit their tokens into the Lido program and receive tokenized staked SOL (stSOL) in return, representing a share of the total pool of staked assets. stSOL can be used like SOL and earns staking rewards, as well as rewards through integrated platforms like Saber and Raydium. The supply of stSOL tracks the number of SOL deposited into the Lido contract and the current exchange rate.
