Summary of the event
On September 8, 2025, third-party service provider CoolWallet Kiln and SwissBorg received an alert about possible unauthorized access to the wallets, which led to the abnormal withdrawal of some of Solana’s assets. SwissBorg and Kiln immediately initiated response measures, successfully halted the irregular activities, and engaged cybersecurity partners to address the issue. To protect users, Kiln has stopped all staking transactions, forced the exit of the validator, and conducted a comprehensive chain-to-chain investigation to ensure the safety and integrity of assets.
During this time, API performance issues temporarily affected display on CoolWallet’s staking pages. To prevent user exposure, CoolWallet immediately cooperated with Kiln in the investigation and continued to monitor the situation. Services are now fully restored.
