Describe the bug
Not sure of the best place to put this issue but here.
@TransmissionsDev noted some odd behavior when getting typescript bindings when using TypeChain.
Using TypeChain for L1 artifacts overwrites pre-existing L2 artifacts typescript bindings and vice versa

Expected behavior
Getting TypeScript bindings for L1 contract artifacts should not overwrite pre-existing TypeScript bindings for L2 contract artifacts or vice versa.
