Hack Compromises SwissBorg’s Solana Holdings
While the hack primarily impacted the SOL Earn protocol, other staking protocols remain unaffected. Despite this, the breach has drained a substantial portion of SwissBorg’s Solana holdings. SwissBorg’s total Solana assets amount to around $72.6 million, so the hack compromised a significant part of its stockpile.
SwissBorg plans to refund affected users using its treasury funds. The company aims to reimburse a significant portion of the lost assets. However, it is unclear whether full compensation will be possible without recovering some of the stolen Solana.
The hack highlights vulnerabilities in partner APIs and underscores the growing risks in the crypto space. API exploits have become increasingly common, and they can bypass even the best internal security measures. As SwissBorg works to recover from the breach, investigators continue to track the stolen assets.
