sPOL is a liquid staking token for POL on Polygon. Users stake POL and receive sPOL, which represents their staked position while remaining liquid and usable across the ecosystem. This allows users to earn staking rewards, including priority transaction fees generated by network activity, while continuing to use sPOL in DeFi applications such as lending, liquidity provision, and trading. The design improves capital efficiency by enabling staked assets to remain productive and accessible.
