Polygon Foundation said in an official announcement that the Giugliano hard fork will activate on Polygon mainnet on April 8 at block height 85,268,500, around 14:00 UTC. The upgrade is intended to improve finality speed, and tests on the Amoy testnet showed final confirmation time was reduced by about two seconds. The foundation also said node operators must upgrade Bor to v2.7.0 or Erigon to v3.5.0 before the fork.
