Use transaction hash for signing #34

Closed juniset closed 2 years ago

Since 0.8.0, the transaction hash is available to the account as part of the tx_info object.

The transaction hash is a hash chain of all the information of the transaction:

A prefix that depends on the transaction type.
The transaction's version.
The Account address.
The Entry point selector.
A hash chain of the calldata (multicall + nonce).
The transaction's maximum fee.
The network's chain ID.

It can thus be used to authorise transactions on an account.

This PR replaces the custom hash_multicall method by the transaction hash.
