the address and creation block look correct to me, but is it correct that the same UR is used for V1_2 and V2_0? I dont know what those specific versions mean in the sdk

@hensha256 yes this should be fine - see entries of other chains above, all have same address for those (except sepolia).
Those are going to come into play once v4 is introduced I believe (related PR here that introduce this split)

@hensha256 v1_2 means UR with v2 and v3, i.e., v2 everywhere. v2_0 means UR with v2 and v3 and v4. Unichain initial deploy will have a single UR with v2 and v3 and v4 right? Hence being the same seems no harm.
