Store number of transactions:
- Total (across all accounts)
- Per account
We can use this to determine overall total transactions and also do a breakdown by user. This kind of query is not possible to do in airflow as querying the chain state for this is not feasible with the number of accounts that we currently have.
Suggested return shape same as cumulativeDexTradeCounts and cumulativeDexTradeCountPerAccounts.
