Lido on Polygon | Bug Bounty Terms

in Polygon by Lido

In collaboration with Shard Labs and Immunefi, we’re pleased to unveil our comprehensive bug bounty program for Lido on Polygon. Earn up to $2 million in bounties - with no KYC requirements - for helping us ensure the security of a cutting-edge liquid staking solution for Polygon.


Get started on


Lido On Polygon

Working in conjunction with Shard Labs, Lido launched liquid staking for Polygon in March 2022.


Built around stMATIC, Lido now lets users earn staking rewards on their MATIC without the need for complex infrastructure or locked/illiquid tokens. With Lido, MATIC ecosystem participants can generate staking rewards and contribute to the security and stability of the Polygon chain through 1-click staking.


Lido on Polygon launched with an initial $1m cap on staked assets. This cap was raised to $10M  and staked assets have since grown to approximately $7.4m at the time of writing.
