We can get storage by ForEachStorage, but all the keys are encrypted in cipher. so this issue aims to design a method as below:

func (db *StateDB) GetVariables(arg abi.Argument) ([]byte, err) 

abi as github.com/ethereum/go-ethereum/accounts/abi. There is an expensive method to meet this demand via getter method provided by EVM.

Can we get it from MPT tree directly?
