Balancer hack: hard fork

Hi Gnosis community,

I’m Luca, the founder of Serenita. We manage a relatively high number of Gnosis Chain validators, where most of the stake has been delegated to us. Because of the fact most of our stake is delegated, we’re interested in gauging community sentiment around this hard fork. We are currently not aware of broad discontent about this rescue operation, and therefore plan to support it with the intent to return hacked funds to their owners.


As you may be aware of, a soft fork is currently in place on Gnosis Chain that prevents the attacker from moving funds through what is basically a very targeted form of censorship (with a single address being censored). Shortly after the hack, we have made the decision to support the soft fork, mainly to buy the Gnosis community some time to make an informed decision on what to do next.

Ideally, we wouldn’t have had to take that decision in the first place. In response to the current situation we would like to (help) set some ground rules based on which we can more easily, and quickly, decide what to do if a similar situation should reoccur. The sooner we can define these rules, the better. If Gnosis Chain is to be a place for low-risk DeFi where we want to do everything possible to rescue hacked funds, we should define exactly what that term means, and the exact conditions under which we want to take severe measures like censoring an address. We strongly want to avoid any unnecessary censorship and irregular state changes.


Onto the hard fork. The hard fork spec defines a BALANCER_RESCUE_ADDRESS set to 0x7Be579238a6a621601Eae2c346cDA54d68F7dfee, and also says that this address “should be a robust multisig or Safe configuration”. However,0x7Be579238a6a621601Eae2c346cDA54d68F7dfee is currently a Safe with a single (seemingly EOA) signer - 0xd722EC6853e6EbAaf8664602A37855FAe872E482. I expect more signers will be added to this Safe before the hard fork date, bringing the Safe under control of the DAO? More clarity on who exactly will be in control of the post-hard fork rescue operation is needed here in my opinion.


Lastly, a huge amount of work went into this behind the scenes, and I want to applaud all involved teams for their efforts!
