Stader is a non-custodial, multi-chain liquid staking platform built for Proof-of-Stake networks like Ethereum and Polygon. It enables users to stake assets and receive liquid tokens, providing seamless access to staking rewards and DeFi opportunities across multiple blockchains.

The SD token is the ERC-20 governance token for the Stader protocol. Its utilities include governance voting, participation in a unique utility pool that rewards decentralization, providing liquidity for incentives, and serving as a bond for permissionless node operators on the network.
