Create a pool example

const compound = true       // Compound interest or not, put the profit back in the pool or not

Borrow example

import { RainFi } from "rainfi-test";
import {signAndSend, loadEnv} from "your-utils"
import { Connection, LAMPORTS_PER_SOL } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com", "confirmed");

// Dump all pools available
const poolAvailable = await RainFi.utils.getAllPoolAvailable(connection)
// Select the pool
const pool = poolAvailable[0]

const duration = 3 // The duration of the loan in DAYS


//Instruction will most likely require more compute unit than the standard of 200k CU. So we ask for more.
const increaseCuIx = ComputeBudgetProgram.requestUnits({
    units: 400000,
    additionalFee: 0,
});

//Create the borrow instruction
const instruction = await RainFi.instructions.borrow(
  connection,
  publicKey!,
  {
    nft_address: "Eb89RFb5MZh4QWaae7m3pMQf5S1eNwUvoaYcpiDGdBfE",  // NFT mint address that you want to collateralize
    pool_owner: pool.owner,                                       // The owner of the pool
    duration: duration,                                           // The duration of the loan in DAYS
  }
