Contagion from the Dec. 12 flash mortgage assault towards Euler has unfold far and vast, leading to frozen or misplaced funds for 11 completely different decentralized finance (DeFi) protocols, in response to Dec. 13 stories from every of them on Twitter. Balancer, an Ethereum protocol with over $1 billion whole worth locked (TVL), is among the many affected protocols. Beneath is a rundown of the key exploits and what we all know thus far.
Balancer
Balancer reported on March 13 that the Euler Boosted USD (bb-e-USD) pool had been affected by the exploit. Roughly $11.9 million price of tokens from this pool had been despatched to Euler through the exploit. The balancer emergency subDAO reacted by pausing the pool and placing it into restoration mode. Nonetheless, over 65% of the pool’s TVL had already been misplaced by the point it was paused.
At 10:00 UTC Balancer contributors grew to become conscious of an exploit on Euler. It was decided the very best plan of action was to pause and put into restoration mode bbeUSD (Euler Boosted USD) and all swimming pools containing bbeUSD. This was executed by the emergency subDAO at 11:00 UTC.

The group has paused all Greatest Yield vaults and Yield Tranches associated to Euler to stop additional losses.
Yearn Finance
Yearn Finance has over $423 million in TVL, in response to DeFi Llama. It reported oblique publicity to Euler, via Angle Protocol and Idle Finance. It has lost roughly $1.38 million. Nonetheless, the group mentioned that any dangerous debt not lined by Idle and Angle can be lined by the Yearn Treasury.
Yield Protocol
Yield Protocol is one other protocol affected by the exploit. Its “mainnet liquidity swimming pools are constructed on Euler,” in response to the group’s announcement relating to the assault. The corporate has disabled the mainnet app, paused borrowing, and is investigating the assault. Its mainnet liquidity swimming pools seem to have been affected, with a doable lack of “lower than $1.5 million.”
The Euler hack has affected our mainnet liquidity swimming pools. Yield liquidity swimming pools maintain two property: Euler eTokens and Yield fyTokens. We don’t but have correct figures for the worth of the eTokens held earlier than the assault however consider the whole worth to be lower than $1.5 million USD.

Different affected protocols
Opyn, Imply, Sense and Harvest additionally reported they may have been affected by the exploit, although none have supplied particulars on how a lot has been misplaced. This brings the whole variety of affected protocols to 11, with $37.6 million in cumulative losses.
