Martin Köppelmann who is the Founder of Gnosis Chain which is the same chain on which Agave protocol is built has tweeted in reply to Shegen that: can’t make any promises, and first we should really understand what happened.

Latest Update

  • 08:58 PM IST, 15th March: According to the twitter thread by BlockSec Team, Agave on the XDai Chain was attacked. They suspect that the attack is through an untrusted external call. The attacker invoked the liquidateCall function to liquidate himself even if he doesn’t have any debt. In the liquidation process, the contract invoked an untrusted external call to the attacker’s contract. In this external call, the attacker deposits 2728 WETH from flash loan to mint 2728 aWETH and borrows everything that is borrowable. When the external call ends, liquidateCall function burns 2728 aWETH and transfers 2728 WETH to the liquidator. Here is a reference image for better understanding.
