Proposal: Update keyRemovalCharge parameter in CSM
The keyRemovalCharge is one of the safety parameters in the Community Staking Module (CSM). Initially, this value was set to 0.05 ETH, with the rationale detailed in the original post: Lido Research Forum – CSM Parameter Discussion.
Since that time, Ethereum gas prices have decreased significantly. The current 8-month average gas price is approximately 11 Gwei. For conservative estimation, we use a higher value of 20 Gwei as the maximum expected gas price.
Following the same methodology used in the original calculation:
Estimated gas cost for queue cleanup: 1,000,000 gas * 20 Gwei = 0.02 ETH
Based on this updated estimate, it is proposed that the keyRemovalCharge be reduced from 0.05 ETH to 0.02 ETH.
This change ensures the parameter remains aligned with current network conditions while maintaining its safety function.
