Layer 2 seems to be a dying narrative already, even before a proper bull run.
Agreed, trend seem to be going back to L1 again, the upcoming project that got heavily invested are bunch of L1, Monad, Berachain and so on, getting hundred million of investment and they are L1.
I think it heavily due to the recent failure of most of L2, milking the community that they destroyed themselves, also, most of people just stick with arbitrum and optimism and some other L2 but that's it, the metric is stuck.
maybe it's because people finally realize that L2 project are just cash cow for developers and investors, so the retailer just decide to opt out and just don't give two damn.
