Euler attack causes locked tokens, losses in 11 DeFi protocols, including Balancer
Contagion from the Dec. 12 flash loan attack against Euler has spread far and wide, resulting in frozen or lost funds for 11 different decentralized finance (DeFi) protocols, according to Dec. 13 reports from each of them on Twitter. Balancer, an Ethereum protocol with over $1 billion total value locked (TVL), is among the affected protocols. Below is a rundown of the major exploits and what we know so far.
Balancer reported on March 13 that the Euler Boosted USD (bb-e-USD) pool had been affected by the exploit. Approximately $11.9 million worth of tokens from this pool were sent to Euler during the exploit. The balancer emergency subDAO reacted by pausing the pool and putting it into recovery mode. However, over 65% of the pool’s TVL had already been lost by the time it was paused.
At 10:00 UTC Balancer contributors became aware of an exploit on Euler. It was determined the best course of action was to pause and put into recovery mode bbeUSD (Euler Boosted USD) and all pools containing bbeUSD. This was executed by the emergency subDAO at 11:00 UTC.
As a result of a bug in the app’s user interface (UI), liquidity providers cannot retrieve the remaining funds left in the pool. However, a new UI will be offered “in the near future” that will allow the remaining funds to be withdrawn, Balancer said. No other pools have been affected, Balancer clarified.
Angle Protocol released a preliminary report on its exposure to the attack. It may have lost over $17 million worth of USD Coin (USDC). This may have caused the agEUR stablecoin, which is pegged to the euro, to become undercollateralized. The team is still investigating and attempting to prepare a detailed balance sheet. All minting and redemption of agEUR is currently paused,
