Lido is a liquid staking solution for ETH backed by industry-leading staking providers. Lido lets users stake their ETH - without locking tokens or maintaining infrastructure - whilst participating in on-chain activities, e.g. lending.
Lido attempts to solve the problems associated with initial ETH staking - illiquidity, immovability and accessibility - making staked ETH liquid and allowing for participation with any amount of ETH to improve performance of the Ethereum network.
