Polygon Mainnet Upped with Ithaca Hardfork Live on July 29
Polygon's mainnet has undergone an upgrade to its network infrastructure with the Ithaca hardfork going live on July 29, 2026. The update, which marks another payments-focused upgrade for Polygon, brings several key improvements aimed at boosting reliability and predictability in transaction processing.
The Ithaca hardfork introduces automatic failover and transaction safeguards as part of network-level changes designed to minimize disruption during operational issues. This means that if something goes wrong on the network, these new features can help mitigate the impact and keep transactions flowing smoothly.
Additionally, improved node-operator visibility has been implemented to enable operators to detect and respond to problems more quickly. This should in turn support continuity at the infrastructure level by making it easier for operators to identify and address issues before they become major problems.
