Market

Reading Market Data

Retrieve market metrics, reserve information, and TVL data using the Kamino SDK and API.

Historical market data is only available via the API.

Get Market Info

Retrieves real-time market-wide metrics including total deposits and borrows TVL across all reserves.

Using the SDK requires a private RPC connection or the public rate-limited RPC endpoint.

TypeScript

getMarketInfo

import { createSolanaRpc, address } from "@solana/kit";
import { KaminoMarket, getMedianSlotDurationInMsFromLastEpochs } from "@kamino-finance/klend-sdk";

const rpc = createSolanaRpc("https://api.mainnet-beta.solana.com");
const marketPubkey = address("7u3HeHxYDLhnCoErrtycNokbQYbWGzLs6JSDqGAv5PfF");

const market = await KaminoMarket.load(rpc, marketPubkey, await getMedianSlotDurationInMsFromLastEpochs());

console.log({
  totalDepositsUsd: market!.getTotalDepositTVL().toFixed(2),
  totalBorrowsUsd: market!.getTotalBorrowTVL().toFixed(2),
});

Get Reserve Info

Queries detailed information for all reserves in the market including deposit/borrow TVL, APY rates, and utilization ratios.

TypeScript
Rust

getReserveInfo

import { createSolanaRpc, address } from "@solana/kit";
import {
  KaminoMarket,
  getCurrentLedgerInstant,
  getMedianSlotDurationInMsFromLastEpochs,
} from "@kamino-finance/klend-sdk";

const rpc = createSolanaRpc("https://api.mainnet-beta.solana.com");
const marketPubkey = address("7u3HeHxYDLhnCoErrtycNokbQYbWGzLs6JSDqGAv5PfF");

const market = await KaminoMarket.load(rpc, marketPubkey, await getMedianSlotDurationInMsFromLastEpochs());
const ledgerInstant = await getCurrentLedgerInstant(rpc);

const reserves = market!.getReserves().map((reserve) => ({
  symbol: reserve.getTokenSymbol(),
  kind: reserve.getKind().toString(),
  supplyAPY: `${(reserve.totalSupplyAPY(ledgerInstant) * 100).toFixed(2)}%`,
  borrowAPY: `${(reserve.totalBorrowAPY(ledgerInstant) * 100).toFixed(2)}%`,
  utilization: `${(reserve.calculateUtilizationRatio() * 100).toFixed(2)}%`,
  depositTvlUsd: reserve.getDepositTvl().toFixed(2),
  borrowTvlUsd: reserve.getBorrowTvl().toFixed(2),
}));

console.table(reserves);

A token can have several reserves: one variable-rate reserve plus fixed-rate ones, so each row shows its kind. Fixed-rate APYs depend on the slot duration passed to KaminoMarket.load. A hard-coded value such as 400 ms shows them at about half their real rate, because mainnet slots are closer to 210 ms.
