support retrieval of detailed info about a specific transaction

[aspiers]

What is needed?

In tx-service mode, the history command displays a nice list of all the transactions, including ones which haven't been executed yet. However, not all the information about each transaction is listed, and there appears to be no other way to retrieve it.

Background

https://github.com/pcaversaccio/safe-tx-hashes-util is able to display a lot of information about a transaction, which is useful for defending against supply chain attacks and ensuring that the right transaction gets signed. It seems strange that the official Safe CLI cannot do the same.

For example, there could be a new subcommand show <nonce> which outputs data like:

• Transaction Data
  • Multisig address
  • To
  • Value
  • Data
  • Operation
  • Safe Transaction Gas
  • Base Gas
  • Gas Price
  • Gas Token
  • Refund Receiver
  • Nonce
  • Encoded message
  • Method
  • Parameters
• Hashes
  • Domain hash
  • Message hash
  • Safe transaction hash
