Describe the task.
Get a typed SDK.
Skip the plumbing.

# plain language, no schema required
"Track every Kamino lending reserve,
 expose current supply APY and
 utilisation, and stream updates
 when a rate moves more than 5 bps."

import { createClient } from "@solanasdk/kamino-reserves";

const sdk = createClient({ apiKey: process.env.SDK_KEY });

// fully typed — no decoding, no PDAs
const reserves = await sdk.listReserves();

reserves.forEach(r => {
  console.log(r.symbol, r.supplyApy, r.utilization);
});

// schema-validated stream
sdk.onRateChange({ minBps: 5 }, e => {
  alert(`${e.symbol}: ${e.from} → ${e.to}`);
});

use solanasdk_kamino::{Client, RateFilter};

}

// stream with a validated shape
let mut s = sdk.rate_changes(RateFilter { min_bps: 5 }).await?;
