[Lido](https://lido.fi/) is primarily a [liquid staking solution](https://blog.lido.fi/introducing-lido/) for [Ethereum](https://stake.lido.fi/) and [Polygon](https://polygon.lido.fi/). Products offered include [liquid staking derivative token contracts](https://lido.fi/#:\~:text=373%2C379-,Supported%20networks,-Lido%20lets%20you) and [other auxiliary smart contract infrastructure](https://docs.lido.fi/deployed-contracts/#lido-on-l2) to support native token staking services.
Lido’s smart contracts [allow](https://docs.lido.fi/#solution) users to stake ETH on Ethereum and [ERC-20 MATIC on Ethereum](https://docs.polygon.lido.fi/#:\~:text=ERC20%20MATIC%20tokens%20on%20Ethereum) to receive the corresponding liquid staking derivative token (i.e., st\[token\]). The protocol then uses these staked tokens to operate validators on the underlying network, increasing participation in each network’s Proof-of-Stake (PoS) consensus mechanism. As such, Lido’s staking solutions are typically meant for users that are unable to run a validator themselves due to economic or technical limitations.
