Liquid staking is transforming the cryptocurrency world by allowing stakers to maintain liquidity of their staked tokens. This innovative approach, introduced by projects like Lido, offers a tokenized representation of staked assets, enabling users to participate in staking without losing control over their holdings. It also allows stakers to earn additional yield through DeFi protocols. The process differs from delegated staking, as it reduces the threshold for investing and avoids the issue of locked tokens. Staking-as-a-service platforms are also emerging, predicted to expand to a $40 billion sector by 2025. However, like any crypto service, liquid staking carries technical and market risks.
