halmos does currently not support the new EVM version cancun (example MCOPY):

↩ 0x5e 0x (error: HalmosException('Unsupported opcode 0x5e'))

In order to formally verify properties given this new EVM version, it would be useful to add support for this new version.

@ByungHeonLEE that would be great!

For TSTORE/TLOAD, the quick and dirty way to do it is to just use the existing SSTORE/SLOAD since atm everything exists in the context of a single transaction.

Longer term, we may want to support multiple transactions, in which case there will be a difference between transient and persistent storage, so it may be useful to have a transient tag on stored values.
