Lido said on Twitter that with the completion of the v2 version upgrade on Polygon, Lido has opened the second round of applications for Polygon node operators, and the application deadline is February 28. Applicants need to meet the requirements of running an active Polygon mainnet validator with ownership of validator slots, maintaining a commission rate of 0 to 5%, and providing detailed infrastructure setup information. The Lido Node Operations sub-governance group will review the submitted applications and make a shortlist to the DAO in March.
