Polygon Ithaca hard fork will go live on the mainnet on July 29, enhancing payment reliability

Jul 22, 2026 08:16:57

The Polygon Foundation posted on the X platform that the Ithaca hard fork has been successfully deployed on the Amoy testnet and will go live on the Polygon mainnet at block height 50,185,000 (expected at 22:00 Beijing time on July 29).

This upgrade aims to enhance payment reliability: automatic failover during rare stalls of block producers ensures smooth transactions, new protective mechanisms intercept transactions that may cause the network to slow down or become unstable, while providing node operators with clearer visibility to ensure seamless integration of underlying operations. All node operators are required to upgrade as soon as possible to ensure compatibility and network security.
