According to L2BEAT analysis, users of the Ethereum Layer 2 network Scroll were overcharged more than $50,000 in transaction fees within about four days last week. The reason is that the Scroll team manually adjusted two rate multipliers in their Gas price oracle six times within six days, increasing each by 2 to 10 times, cumulatively raising the L1 data cost parameter to 1,280 times the original benchmark.Approximately 139,000 affected transactions originally had a total cost of only about $280, but were actually charged over $50,000, with automated bots accounting for the vast majority. L2BEAT pointed out that the overcharging was not an issue with the sequencer, but rather stemmed from the team's multiplier adjustments executed through a multi-signature wallet. This incident has raised questions about whether Scroll had previously subsidized users with rates below cost to maintain activity. According to DeFiLlama data, Scroll currently has a TVL of only $24 million, down 96% from its peak of $585 million in October 2024. As of the time of publication, Scroll has not publicly responded.

ChainCatcher news, according to Cointelegraph, users of the Blast network cryptocurrency lending application Pac Finance reportedly suffered a liquidation of $24 million on April 11 due to a sudden change in parameters by the developer's wallet. An official Discord administrator claimed they had notified the team about the issue. The official team has not yet issued a statement regarding this matter.It is reported that Pac Finance allows cryptocurrency holders to deposit funds and earn interest by lending capital. To ensure repayment, the application only allows borrowers to take out loans equivalent to a certain percentage of the collateral value. This percentage is known as the "Loan-to-Value" (LTV) ratio. The LTV can be changed by the development team, but it is usually only executed after an announcement.According to blockchain data from the Blast network, the Pac Finance developer wallet called a function on its PoolConfigurator-Proxy contract at 1:06 AM UTC on April 11, setting the LTV for ezETH at 60%.

ChainCatcher news, the Aave community has initiated a new ARFC proposal aimed at adjusting the risk parameters of the DAI stablecoin.It is reported that the proposal was put forward by the Aave Chan Initiative (ACI) team, recommending to adjust the loan-to-value ratio (LTV) of DAI to 0% across all Aave deployments and to remove sDAI incentives from the Merit program, effective from Merit Round 2 and onwards.Additionally, this move is intended to address the aggressive actions of MakerDAO's recent D3M plan, which has caused DAI's credit line to grow from zero to a projected 600 million DAI in less than a month, and potentially increase to 1 billion DAI in the short term, thereby increasing the risk of DAI as collateral. Considering that currently only a small portion of DAI deposits are used as collateral on Aave, and users can easily switch to USDC or USDT as alternative collateral options, the purpose of the proposal is to mitigate potential risks without significantly impacting the user base.
