it does not really solve the problem. It does noticeably speed up load times for wallets with agora txs in history, tho need to wait for the wallet to load tx history from chronik to get 10 instead of the 20 that will be cached. The speed issue comes from processing the 20 -- we need to cache them better, load and parse async.
