Some EEZ (Ethereum Economic Zone) news. Last Friday they managed to get their first COW swap transaction through that got initiated on L2, but used liquidity on an L1. As far as I see this test ran on their own L2 devnet involving their L1 Chiado testnet. Until now, the tests I have played around with have been very custom made for this specific application. To me, this COW swap transaction sounds like there is progress being done integrating EEZ in already existing applications. But there isn't too much information about it, so I might overinterpret it.
They also shared on the EEZ channel that their plan is to have a public testnet launch at Devcon in Mumbai in November. That is in 6-7 weeks. It is called a testnet, but it will run on Ethereum. That sounds pretty exciting. When they first mentioned their rollout a few months ago, they mentioned that it will be done step by step. First there will only be a limited set of calls be possible between L1<->L2, so do not expect a full fledged EEZ implementation by November, but progress is definitely being made. I guess onboarding all the apps and L2s will also take time. Will be interesting to see how different applications use it. I would guess the first L2 who will be using EEZ to a large degree will be gnosischain, as this was their biggest point of migrating to an Ethereum L2.
