Gas Price Spikes

Gas price spikes occur when network demand on a blockchain, such as Ethereum, exceeds its processing capacity, leading to a sharp increase in transaction fees. For DeFi protocols, these spikes are particularly dangerous because they can make time-sensitive operations, like liquidations or margin calls, prohibitively expensive or slow.

If a liquidation transaction is stuck in the mempool due to low gas, the protocol cannot recover collateral in time, increasing the risk of bad debt. Furthermore, users may be unable to manage their positions or move funds during market crashes, exacerbating the impact of the volatility.

This creates a feedback loop where market stress drives up transaction demand, which in turn increases gas costs and hinders the very mechanisms meant to stabilize the system. Developers must optimize contract code and utilize Layer 2 solutions to mitigate the impact of these network congestion events.
