feat: activity section

[Agilulfo1820]

We should show user's activities.
When a smart account is used it could be difficult to interpret if we fetch data from an indexer.

We could also store everything locally with cache, but then I don't think we can fetch incoming transactions (in a scalable way)

I can think of two things to avoid a specific indexer:

• a subgraph
• storing transaction records on-chain, in the Smart Account contract

@Agilulfo1820 WDYT?

[Agilulfo1820]

Not sure about it, I would like to have a brainstorming meeting on this so we could add some requirements so we can better understand what technology to use to achieve that.

@daithihearn
maybe you can offer this kind of information on the block explorer you are building?
Ok, let's have a session.
