How to track the Ether liquid staking market

This DefiLlama "ETH Liquid Staking" dashboard tracks the liquid staking market, where protocols stake users' Ether and issue liquid staking tokens that can be used elsewhere in DeFi. Lido is the largest protocol, having issued $14.5 billion worth of its stETH token, and the article says it holds over $18.4 billion of DeFi's $38 billion TVL in liquid staking protocols. The dashboard offers pie and area charts of protocol market share, an Inflows tab showing flows into and out of each protocol, and a table with metrics such as TVL, peg and APR. The article notes that outflows spiked on May 18, 2023, the day Ethereum's Shapella upgrade enabled withdrawals, but later inflows have outweighed them.
