 #### Will address derivation with regular `create` and `create2` be the same as on other EVM chains?
 Yes.
 
+#### Is it possible to check if a contract was deployed with EVM bytecode?
+Yes. The `AccountCodeStorage` system contract (deployed on `0x0000000000000000000000000000000000008002`) has a
+function `isAccountEVM(address)` that returns `true/false`.

 #### Is the EVM interpreter 100% compatible with EVM?
 No. Although interpretation covers most developers' needs, there are limitations due to the underlying EraVM, such as unsupported opcodes or gas differences.
 Full EVM equivalence is expected with the next proving system in **2025**.
