🔥 @0xPolygon is set to implement the Heimdall v2 upgrade on July 10th

#Polygon is set to undergo its #Heimdallv2 migration on July 10th between 14:00 and 17:00 UTC, marking the most technically complex hard fork for Polygon PoS since its inception. Heimdall v2 eliminates legacy tech debt from its 2018–19 architecture, upgrading from #Tendermint and Cosmos-SDK v0.37 to #CometBFT and Cosmos-SDK v0.50, reducing finality to around X seconds with no reorgs beyond two blocks.
