Overview

Represent ‘reduced` transaction, i.e. unsigned transaction where each unsigned input is augmented with ReducedInput which contains a script reduction result. After an unsigned transaction is reduced it can be signed without context. Thus, it can be serialized and transferred for example to Cold Wallet and signed in an environment where secrets are known. see EIP-19 for more details
