TL;DR:
Polygon launched sPOL, its native liquid staking token, as a response to one of the most persistent structural problems in its ecosystem: more than 95% of staked POL remained locked and inactive in the DeFi market. According to the official announcement from Polygon Labs, more than 3.6 billion POL are currently staked, yet only between 4% and 5% of that capital circulates in liquid form. sPOL aims to change that equation directly.
The contract was audited by ChainSecurity and Certora, and received immediate backing of 10 million POL from the Polygon Labs treasury on its first day of operation. An additional 90 million are scheduled to be added progressively, reaching a total of 100 million. AMM pools on Uniswap V4 have been active since launch, with no need for the market to build its own initial liquidity.
Those already participating in staking with a validator can migrate their position to sPOL through Polygon’s official portal, with no waiting periods or interruptions to rewards. The exchange rate starts at a 1:1 ratio with POL and appreciates progressively as rewards accumulate. The sPOL balance does not change, but each token represents a growing amount of POL over time.
Once obtained, sPOL can be used like any DeFi asset: providing liquidity, using it as collateral, or combining yield strategies on top of base staking rewards. Redemption for POL plus accumulated returns can be carried out at any time from the portal.
The launch also addresses a distribution problem. Polygon Labs notes that most of the priority fees generated by activity on the network do not reach stakers. Validators integrated into the sPOL program commit to returning a portion of those fees to delegators, aligning economic incentives with those who secure the network.
On Ethereum, approximately 30% of staked ETH is represented by liquid staking tokens. On Polygon, that figure does not exceed 5%. Existing protocols charge fees ranging from 5% to 16%, a gap that the platform identifies as the primary reason for the lag.
