While this is usually very convenient, it means that we can’t assert on the behaviour/state of *different* EVMs from within a fuzzing campaign. This means we will have to walk around the requirement of supertokens having the same address across all chains, and implement a way to mock tokens existing in different chains.

While this is usually very convenient, it means that we can’t assert on the behaviour/state of *different* EVMs from within a fuzzing campaign. This means we will have to walk around the requirement of supertokens having the same address across all chains, and implement a way to mock tokens existing in different chains. We will strive to formally prove it in a unitary fashion to mitigate this in properties 0 and 1 -- a buffer to represent 'in transit' messages should be implemented to assert on invariants relating to the non-atomicity of bridging from one chain to another.
