The following protection code in fungible\keeper\evm_hooks.go is totally redundant as if you trace back where hooks are called (with PostTxProcessing) in ethermint@v0.22.0::state_transition.go you can see that receipt parameter even if passed as a pointer can never be nil. Otherwise in case you are paranoid and like redundant code and would like to keep it somehow, then add the same protection at least in crosschain\keeper\evm_hooks.go so that is consistent accross the protocol.
