All delivered via one new WebSocket subscription: preconfSubscribe

Get a wallet's balance at any point in time
The new balance-at endpoint returns a wallet's exact SOL or SPL token balance at a given date or slot

@therealricoy +1 to this. Early on we had some pretty specific features requests and they pulled an all nighter to have it live the next day

helius is the only solana-exclusive RPC for a reason
that focus allows us to ship APIs like this for solana devs that are an order of magnitude better than anything else
if 100x lower latency & fewer API calls weren't enough, we've now increased bandwidth 10x & reduced prices
