On September 10-11, 2025, the Polygon network experienced temporary disruptions due to a bug in Bor and Erigon nodes, leading to a price dip in the POL token. Nevertheless, thanks to the prompt response from the developer team, network stability was restored quickly.
Causes of Network Disruption
The disruption was caused by a bug in the Bor and Erigon nodes, which led to significant finality delays and RPC disruptions. Polygon co-founder Sandeep Nailwal confirmed that the incident was due to a 'faulty proposal' by a validator, which pushed several Bor nodes onto separate forks and halted block production.
Impact on POL Token
During the outage, the POL token experienced a temporary 4% price dip. However, following the stabilization of the network, the token's price rebounded despite temporary challenges in applications and transaction delays.
Outcomes and Consequences of the Incident
There were no significant outflows or drops in Total Value Locked (TVL), indicating that funds remained secure and Ethereum's security was intact. The restoration of normal operations was quickly verified by leading blockchain explorers. The developer team continued to monitor the network to ensure its integrity.
The event underscores the importance of swift technological interventions to mitigate risks, as well as the significance of strategic node management in blockchain networks. The Polygon market stabilized with minimal lingering effects.
