    function require_evm_signatures_can_be_used()
    source

    Ensures that this operation is authorizing an operation which is whitelisted for usage with evm_signatures

    The operation that is being authorized should be the next operation in the transaction, but it's allowed to have an auth operation or a strategy operation between this operation and the authorized one.

    Throws "EVM SIG FORBIDDEN" if:

    • the operation that is being authorized is not whitelisted,
    • there's no operation after this one, or
    • there is only one operation after this one, and it's an auth or strategy operation

    Can only be called from an operation, and it should only be called by evm_signatures
