The design space of Ethereum rollups is huge. I am not going to deny that assessing @0xFacet was challenging for the whole team as its design is not what you would expect from a typical rollup. Nevertheless we love being challenged and as a result some new dashboards related to canonical and externally-bridged assets are in the works. The most challenging aspect of @0xFacet is undoubtedly its non-standard gas token. It's use challenges the core definition of a "canonical" asset as normally we assume that gas token must be bridged canonically but what if you don't really "bridge" gas token at all ? What is a canonical asset and canonical bridge then ? Read the full review and @0xFacet announcement for more technical details.
