Use it in your code

Load the SPL Token Lending IDL with Anchor in TypeScript, Rust or Python.

import { Connection, PublicKey } from "@solana/web3.js";
import { Program, AnchorProvider, Idl } from "@coral-xyz/anchor";

// Load the SPL Token Lending IDL
import idl from "./spl token lending.json";

const PROGRAM_ID = new PublicKey("LendZqTs8gn5CTSJU1jWKhKuVpjJGom45nnwPb2AMTi");

// Set up the provider and program
const connection = new Connection("https://api.mainnet-beta.solana.com");
const provider = new AnchorProvider(connection, wallet, {
  commitment: "confirmed",
});
const program = new Program(idl as Idl, provider);

// Fetch and decode an account
const accountData = await program.account.sPL_Token_Lending
  .fetch(accountPublicKey);
console.log("Account data:", accountData);

// Build and send an instruction
const tx = await program.methods
  .initialize(/* ...args */)
  .accounts({
    /* ...required accounts */
  })
  .rpc();
console.log("Transaction signature:", tx);

Frequently asked questions

What is the SPL Token Lending IDL?

The SPL Token Lending IDL (Interface Definition Language) is a JSON schema that describes the on-chain program interface for the SPL Token Lending smart contract on Solana. It defines all available instructions, account structures, events, and types needed to interact with the program. This one has 15 instructions, 3 account types, 0 events and 7 type definitions.

How do I use the SPL Token Lending IDL in my project?

You can use the SPL Token Lending IDL with Anchor framework clients in TypeScript (@coral-xyz/anchor), Rust (anchor-client), or Python (anchorpy). Download the JSON file, import it in your project, and use it to create a Program instance that can call instructions and decode accounts.

What is the SPL Token Lending program address on Solana?

The SPL Token Lending program is deployed at address LendZqTs8gn5CTSJU1jWKhKuVpjJGom45nnwPb2AMTi on Solana mainnet.

What version of the SPL Token Lending IDL is this?

This is version 0.2.0 of the SPL Token Lending IDL. IDL versions follow program deployments and change as the protocol evolves, so check it against the program on-chain before you integrate.

Build on SPL Token Lending with AllenHark

Stream the program's accounts and transactions with Yellowstone gRPC, read its state over Solana RPC, or see its transactions before the block is built with ShredStream. To trade against it, try the trading bots or the PumpFun sniper.
