YAM Finance responds to Inverse attack: Suspicious transactions originated from LlamaLend, not a contract vulnerability

According to BlockSec monitoring, Inverse Finance is suspected of suffering a loss of approximately $240,000 due to an attack. YAM Finance responded in a post on platform X, stating that this incident is not a vulnerability in the Inverse contract, but rather related to the LlamaLend mechanism.

According to their explanation, the attacker initiated a "donation attack" on sDOLA on LlamaLend, driving the price from about 1.188 sDOLA = 1 DOLA up to about 1.358 sDOLA = 1 DOLA, and subsequently liquidated almost all user positions that had crvUSD borrowed against sDOLA as collateral. It is still unclear why the increase in collateral value triggered liquidations, as it should logically keep users away from the liquidation line rather than bring them closer.

It is worth noting that the "secondary effects" of this price anomaly are still ongoing. As a result, users who did not engage in leveraged operations on LlamaLend and only held sDOLA have seen their paper profits increase by about 14%. Additionally, DOLA is currently trading at about a 1% discount in the secondary market compared to its pegged value, and some community members suggest that borrowing users consider repaying their DOLA debts during this discount phase.
