Polygon has introduced a fix intended to stabilize the network. We are actively validating these changes through our systems. As mitigation takes effect, customers may see incremental improvements, though intermittent impact is still possible until full stabilization is confirmed.
We are currently investigating degraded performance affecting Polygon Mainnet. A subset of nodes appears to be stalled, and early indicators suggest a broader, chain-wide issue. We are actively coordinating with the Polygon team and will provide updates as more information becomes available.
