Polygon Heimdall V2 Outage Halts Network for 1 Hour, POL Down 3%
On July 30, 2025, a validator exit triggered a consensus bug in the Polygon Heimdall V2 layer. The Polygon outage halted consensus for one hour, though the Bor execution layer continued processing transactions. Several RPC providers then faced sync inconsistencies, causing explorers and dApps to report false downtime. Developers deployed a patch by 11:01 UTC and are working with providers to restore full RPC sync. With over $1.4 billion TVL and the recent Heimdall V2 upgrade—featuring CometBFT integration and five-second finality—this Polygon outage highlights risks tied to added system complexity. The incident shaved nearly 3% off the POL token price and may weigh on trader confidence. Crypto traders should monitor RPC status and network health indicators to anticipate any residual transaction delays.
Bearish
Despite the Bor layer’s uninterrupted performance, the Polygon Heimdall V2 outage and ensuing RPC sync issues led to a near 3% drop in POL. The consensus-layer halt and false downtime reports have shaken user confidence and could trigger increased volatility in the short term. In the long run, improved validator-exit handling and RPC resilience may mitigate future risks, but for now the market reaction is negative, marking a bearish outlook for POL.
