The Ethereum restaking protocol EigenLayer has seen an influx of over $1 billion in deposited crypto within 48 hours of reopening. This surge has benefited other liquid staking protocols like Swell and Stader. EigenLayer's unique offering of restaking has sparked excitement in the crypto economy, with the protocol set to offer larger annual yields for restaking Ether in the future. However, there are concerns about the potential impact of restaking on Ethereum's stability and whether the increased annual yield is sustainable. EigenLayer is cautious in its phased rollout and is set to support additional liquid staking tokens in the future.
