Prerequisites

Install packages in your working directory:
npm install @lightprotocol/stateless.js@alpha \
            @lightprotocol/compressed-token@alpha
Install the CLI globally:
npm install -g @lightprotocol/zk-compression-cli@alpha

# start local test-validator in a separate terminal
light test-validator
In the code examples, use createRpc() without arguments for localnet.

Mint Tokens to Light-ATA

import "dotenv/config";
import { Keypair } from "@solana/web3.js";
import { createRpc } from "@lightprotocol/stateless.js";
import {
    createMintInterface,
    createAtaInterface,
    mintToInterface,
    getAssociatedTokenAddressInterface,
} from "@lightprotocol/compressed-token";
import { homedir } from "os";
import { readFileSync } from "fs";

// devnet:
const RPC_URL = `https://devnet.helius-rpc.com?api-key=${process.env.API_KEY!}`;
// localnet:
// const RPC_URL = undefined;
const payer = Keypair.fromSecretKey(
    new Uint8Array(
        JSON.parse(readFileSync(`${homedir()}/.config/solana/id.json`, "utf8"))
    )
);

(async function () {
    // devnet:
    const rpc = createRpc(RPC_URL);
    // localnet:
    // const rpc = createRpc();

    const { mint } = await createMintInterface(rpc, payer, payer, null, 9);

    const recipient = Keypair.generate();
    await createAtaInterface(rpc, payer, mint, recipient.publicKey);

    const destination = getAssociatedTokenAddressInterface(mint, recipient.publicKey);
    const tx = await mintToInterface(rpc, payer, mint, destination, payer, 1_000_000_000);

    console.log("Tx:", tx);
})();
