Best Practices

Health Factor Monitoring

async function checkHealthFactor(
  market: KaminoMarket,
  wallet: PublicKey
): Promise<number> {
  await market.refreshAll();
  const obligation = await market.getUserVanillaObligation(wallet);

  if (!obligation) return Infinity;

  const stats = obligation.refreshedStats;
  const healthFactor = stats.borrowLimit / stats.borrowedValue;

  if (healthFactor < 1.1) {
    console.warn("WARNING: Health factor below 1.1, consider adding collateral");
  }

  return healthFactor;
}

Transaction Optimization

// Use lookup tables for smaller transactions
const { instructions, lookupTables } = await kaminoAction.buildWithLookupTables();

// Create versioned transaction
const messageV0 = new TransactionMessage({
  payerKey: wallet.publicKey,
  recentBlockhash: (await connection.getLatestBlockhash()).blockhash,
  instructions,
}).compileToV0Message(lookupTables);

const tx = new VersionedTransaction(messageV0);
tx.sign([wallet]);

await sendAndConfirmTransaction(connection, tx, [wallet]);

Slippage Protection

// For liquidity operations, always use slippage protection
const slippage = new Decimal(0.005); // 0.5% max slippage

const depositIxs = await kamino.deposit(
  strategy,
  wallet.publicKey,
  tokenAAmount,
  tokenBAmount,
  slippage  // Protects against price movement
);

Failure handling

Error Handling

import { KaminoError, ErrorCode } from "@kamino-finance/klend-sdk";

try {
  await kaminoAction.execute();
} catch (error) {
  if (error instanceof KaminoError) {
    switch (error.code) {
      case ErrorCode.InsufficientCollateral:
        console.error("Not enough collateral for this borrow");
        break;
      case ErrorCode.BorrowLimitExceeded:
        console.error("Borrow limit reached for this reserve");
        break;
      case ErrorCode.LiquidationThresholdExceeded:
        console.error("Position is at risk of liquidation");
        break;
      case ErrorCode.InvalidObligation:
        console.error("Obligation account not found or invalid");
        break;
      default:
        console.error("Kamino error:", error.message);
    }
  } else {
    throw error;
  }
}

Kamino Lending (klend-sdk)

The lending SDK enables interaction with Kamino's lending markets for deposits, borrows, repayments, and liquidations.

Core Classes

| Class | Purpose | |-------|---------| | KaminoMarket | Load and interact with lending markets | | KaminoAction | Build lending transactions (deposit, borrow, repay, withdraw) | | KaminoObligation | Manage user obligations (positions) | | KaminoReserve | Access reserve configurations and stats | | VanillaObligation | Standard obligation type |

Initialize Market

import { KaminoMarket } from "@kamino-finance/klend-sdk";

// Main lending market address
const MAIN_MARKET = new PublicKey("7u3HeHxYDLhnCoErrtycNokbQYbWGzLs6JSDqGAv5PfF");

// Load market with basic data
const market = await KaminoMarket.load(connection, MAIN_MARKET);

// Load reserves for detailed data
await market.loadReserves();

// Get specific reserve
const usdcReserve = market.getReserve("USDC");
console.log("Total Deposits:", usdcReserve?.stats.totalDepositsWads.toString());
console.log("LTV:", usdcReserve?.stats.loanToValueRatio);
console.log("Borrow APY:", usdcReserve?.stats.borrowInterestAPY);
console.log("Supply APY:", usdcReserve?.stats.supplyInterestAPY);

// Refresh all data including obligations

Scope Oracle (scope-sdk)

Oracle price aggregator providing reliable pricing data.

Initialize Scope

import { Scope } from "@kamino-finance/scope-sdk";
import { Connection, clusterApiUrl } from "@solana/web3.js";

const connection = new Connection(clusterApiUrl("mainnet-beta"));
const scope = new Scope("mainnet-beta", connection);

Get Oracle Prices

// Get all oracle prices
const prices = await scope.getOraclePrices();

// Prices indexed by token
console.log("SOL Price:", prices.get("SOL"));
console.log("USDC Price:", prices.get("USDC"));

// Get specific price
const solPrice = await scope.getPrice("SOL");
console.log("SOL/USD:", solPrice.price.toString());
console.log("Timestamp:", solPrice.timestamp);
console.log("Confidence:", solPrice.confidence);

Price Feeds

Scope aggregates from multiple oracle sources:

  • Pyth: Real-time market prices
  • Switchboard: Decentralized oracle network
  • TWAP: Time-weighted average prices
  • CLMM Prices: DEX-derived prices
// Get price with source info
const priceData = await scope.getPriceWithMetadata("SOL");
console.log("Price:", priceData.price);
console.log("Source:", priceData.source);
console.log("Age (slots):", priceData.ageSlots);

Best Practices

Health Factor Monitoring

async function checkHealthFactor(
  market: KaminoMarket,
  wallet: PublicKey
): Promise<number> {
  await market.refreshAll();
  const obligation = await market.getUserVanillaObligation(wallet);

  if (!obligation) return Infinity;

  const stats = obligation.refreshedStats;
  const healthFactor = stats.borrowLimit / stats.borrowedValue;

  if (healthFactor < 1.1) {
    console.warn("WARNING: Health factor below 1.1, consider adding collateral");
  }

  return healthFactor;
}

Transaction Optimization

// Use lookup tables for smaller transactions
const { instructions, lookupTables } = await kaminoAction.buildWithLookupTables();

// Create versioned transaction
const messageV0 = new TransactionMessage({

Slippage Protection

// For liquidity operations, always use slippage protection
const slippage = new Decimal(0.005); // 0.5% max slippage

const depositIxs = await kamino.deposit(
  strategy,
  wallet.publicKey,
  tokenAAmount,
  tokenBAmount,
  slippage  // Protects against price movement
);
