Overview - Developer Docs

Users deposit assets into Earn vaults or supply them to Kamino’s lending markets as collateral to borrow against. Developers can integrate the same flows using the SDK’s composable methods for deposits, borrows, repayments, and withdrawals.

Integrate Kamino

Developers can integrate Kamino using the Kamino Typescript SDK or the Kamino REST API.

REST API

REST API for vault lists, performance metrics, user positions, and transaction history.

TypeScript SDK

Compose on-chain transactions for deposits, borrows, repayments, and withdrawals.

Getting Started

Set up your development environment:

Install SDK

Install the K-Lend Typescript SDK and Solana Kit packages.

npm i @kamino-finance/klend-sdk @solana/kit

Setup the RPC (optional)

Use a private RPC for reliability. Public RPCs are often rate-limited and can cause transaction failures.

Multiple RPC providers are available. Helius is one option. @solana/kit is used for standardized RPC interactions with improved type safety and better handling of Solana transactions.

import { createSolanaRpc } from '@solana/kit';

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

Create or Import Wallet (optional)

Choose a method to create or import a wallet for signing transactions.

Alternatively, create a wallet using a browser wallet provider like Phantom.

Show Create with CLI

Use the Solana CLI to generate a new keypair file.

solana-keygen new -o wallet.json

Show Create with Solana Kit

Generate a new keypair programmatically using the Solana Kit.

import { generateKeyPairSigner } from "@solana/kit";

const signer = await generateKeyPairSigner();
console.log("address: ", signer.address);

Show Import Keypair File

Import a wallet from an existing keypair file.

import { createKeyPairSignerFromBytes } from '@solana/kit';
import fs from 'fs';
import path from 'path';
import os from 'os';

const resolvedPath = path.resolve(
  filePath.startsWith("~") ? filePath.replace("~", os.homedir()) : filePath
);
const loadedKeyBytes = Uint8Array.from(
  JSON.parse(fs.readFileSync(resolvedPath, "utf8"))
);
const signer = await createKeyPairSignerFromBytes(loadedKeyBytes);
console.log(signer.address);

Show Import Private Key

Import a private key from an existing browser wallet.

import { createKeyPairSignerFromBytes } from '@solana/kit';

// Get your private key from browser wallet (as Uint8Array or number array)
const privateKey = new Uint8Array([/* your private key bytes */]);
const signer = await createKeyPairSignerFromBytes(privateKey);
