Kelp hack could leave Aave on Arbitrum with bad debt and make rsETH worthless if only mainnet rsETH is backed. But the Arbitrum DAO was quick enough to withdraw its assets from Aave after the hack. They had $10M in ETH and ~$5M in stables on Aave, earning yield via the Treasury Management Program. Managed by Entropy Advisors, they quickly withdrew everything. Interestingly, they also withdrew stables from Spark and now only hold some on Morpho, with the other half currently unallocated.(Ignas | DeFi)
