Scroll users were overcharged more than $50,000 in fees after the team manually increased the fee rate parameter.

Mars Finance reports that, according to L2BEAT analysis, users of Ethereum Layer 2 network Scroll were overcharged more than $50k in transaction fees within approximately four days. The reason is that the Scroll team manually increased two fee rate multipliers in its Gas Price Oracle six times over six days, each time raising them by 2 to 10 times, cumulatively increasing the L1 data cost parameter to 1,280 times the original baseline. About 139,000 affected transactions, which originally cost only around $280 in total, were actually charged over $50k, with the vast majority caused by automated bots. L2BEAT pointed out that the overcharge was not due to a sequencer issue but resulted from the team executing multiplier adjustments via a multisignature wallet. This incident has sparked public suspicion that Scroll may have previously subsidized users at below-cost rates to maintain activity. According to DeFiLlama data, Scroll’s current TVL is only $24 million, down 96% from the peak of $585 million in October 2024. As of press time, Scroll has not publicly responded.
