By ToTo BugelmanNewcomer0 rep· 9/9/2025

SwissBorg, a prominent cryptocurrency platform, has fallen victim to a significant security breach, resulting in the loss of approximately $40 million worth of SOL. The incident, which occurred on September 8th, targeted the platform's SOL Earn product through a compromised partner API. While the main SwissBorg app and other 'Earn' programs remain secure, the attack has prompted swift action from the company to address user compensation.

Key Takeaways

  • Approximately 192,600 SOL, valued at $41 million, was stolen.

  • The hack impacted the SOL Earn program via a compromised partner, Kiln, which provides staking infrastructure.

  • SwissBorg assures that less than 1% of its user base was affected and that the core application is secure.

  • A recovery plan is in place, with SwissBorg pledging to cover all user losses.

 

Details of the Breach

The attack was first brought to light by on-chain detective ZachXBT. Investigations revealed that the vulnerability stemmed from a compromised partner API belonging to Kiln, a service provider for Solana and Ethereum staking. SwissBorg has stated that the incident did not affect the overall security of its application or other 'Earn' programs, emphasizing that the company remains in a strong financial position and daily operations are unaffected.

SwissBorg's Response and Recovery Plan

In response to the breach, SwissBorg has outlined a comprehensive recovery plan. The company has committed to fully compensating all users who incurred losses due to the SOL Earn program exploit. This proactive approach aims to restore user confidence and mitigate the impact of the security incident.

 

Broader Context of Crypto Security

This incident at SwissBorg occurred on the same day that the DeFi platform Nemo, built on Sui, also experienced a security breach, with hackers making off with $2.4 million in USDC. The stolen funds were reportedly moved from Arbitrum to Ethereum. Nemo's team has temporarily suspended smart contract activity while investigating the cause, assuring users that assets in vaults are safe. These events highlight the persistent security challenges within the cryptocurrency ecosystem.
