Earlier this week, the SwissBorg cryptocurrency exchange platform was the victim of a theft estimated at over $40 million. The incident involved the Solana staking module set up by the Kiln crypto project, which has just announced the removal of all its Ethereum (ETH) validators as a precautionary measure.
Kiln initiates the exit of its Ethereum validators
On September 9, the SwissBorg cryptocurrency exchange platform was impacted by the hack of a partner used for its staking operations, resulting in a loss of more than $40 million in SOL cryptocurrency.
The attack was quickly detected by the exchange, which triggered a joint response with its partner Kiln, in charge of the compromised staking strategy, with the activation of an incident management plan and a pause in staking operations to ensure the safety of SwissBorg users.
Once the incident was under control, Kiln officials decided to “take additional precautionary measures to protect customer assets on all networks.” The goal of this operation? To guarantee the integrity of the cryptocurrencies involved while ensuring the reliability of the infrastructure developed by Kiln, according to the project’s co-founder and CEO, Laszlo Szabo.
We took immediate action once we identified a potential compromise in our infrastructure. The exit of [Ethereum] validators is the responsible step to protect stakers, and we are closely monitoring the process to ensure the security and reliability of our services.

A process that could take up to 45 days
This decision by the Kiln project involves a large-scale operation. Its staking services are used by many leading cryptocurrency exchanges, but they are also present on central protocols of decentralized finance (DeFi) such as EigenLayer, to the point of representing a 6% market share of staking on Ethereum, according to data highlighted on its website.
Furthermore, this is not necessarily the best time to initiate a massive unstaking process for Ethereum validators. The queue is currently experiencing historically long congestion, with a fixed duration of more than 45 days.
The exit process is expected to take between 10 and 42 days depending on the validator, after which withdrawals will occur as scheduled by the network, which can take up to 9 days.

This is a waiting period over which Kiln has no control. However, the project explains that “validators continue to receive rewards while they are in the exit queue.” At the same time, Kiln has announced the temporary suspension of access to some of its services in order to conduct a comprehensive review of its infrastructure before publishing a detailed report.
