Show that a transaction occurred

[olaven]

Goal

After the user has gone through #38, #39 and #40, a transaction should have occurred (#55). We want to show this to our audience.

TODO

• Figure out how we can show this
• Implement whatever we figure out

@aridder In my mind, we want to inspect balances of two Ethereum accounts, show how they changed and show the transaction. What do you think is the easiest way to do this?
