Integration Examples
Use the SPL Token Swap IDL in your application with these code examples for TypeScript, Rust, and Python.
import { Connection, PublicKey } from "@solana/web3.js";
import { Program, AnchorProvider, Idl } from "@coral-xyz/anchor";
// Load the SPL Token Swap IDL
import idl from "./spl token swap.json";
const PROGRAM_ID = new PublicKey("SwaPpA9LAaLfeLi3a68M4DjnLqgtticKg6CnyNwgAC8");
// 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_Swap
.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);IDL JSON Preview

...Frequently Asked Questions
What is the SPL Token Swap IDL?
The SPL Token Swap IDL (Interface Definition Language) is a JSON schema that defines the on-chain program interface for the SPL Token Swap smart contract on Solana. It describes all available instructions, account structures, events, and custom types that developers need to interact with the SPL Token Swap program. This IDL contains 6 instructions, 6 account types, 0 events, and 1 type definitions.
How do I use the SPL Token Swap IDL in my project?
Download the JSON file and import it in your project. With TypeScript, use the @coral-xyz/anchor package to create a Program instance. In Rust, use anchor-client. For Python, use anchorpy. See the integration examples above for complete code snippets in all three languages.
What is the SPL Token Swap program address on Solana?
The SPL Token Swap program is deployed at address SwaPpA9LAaLfeLi3a68M4DjnLqgtticKg6CnyNwgAC8 on Solana mainnet. You can verify this on any Solana block explorer.
What version of the SPL Token Swap IDL is this?
This is version 3.0.0 of the SPL Token Swap IDL. IDL versions correspond to specific program deployments and may be updated as the protocol evolves. Always verify compatibility with the on-chain program version before integrating.
