Lookup Tables

Lookup tables reduce your transaction size. We provide pre-initialized lookup tables that cover the Light's program IDs and accounts:

Lookup Table #1 (Mainnet)	9NYFyEqPkyXUhkerbGHXUXkvb4qpzeEdHuGpgbgpH1NJ
Lookup Table #1 (Devnet)	qAJZMgnQJ8G6vA3WRcjD9Jan1wtKkaCFWLWskxJrR5V

We provide a helper function below if you need to extend a custom lookup table.

ExtendLookUpTables.ts

import { Rpc, confirmTx, createRpc } from "@lightprotocol/stateless.js";
import { createTokenProgramLookupTable } from "@lightprotocol/compressed-token";
import { Keypair, PublicKey} from "@solana/web3.js";
import { RPC_ENDPOINT } from "./constants";
const payer = Keypair.generate();
const authority = payer;
const additionalTokenMints : PublicKey[] = [];
const additionalAccounts : PublicKey[] = [];

// Localnet
const connection: Rpc = createRpc();

const main = async () => {
  /// airdrop lamports to pay gas and rent
  await confirmTx(
    connection,
    await connection.requestAirdrop(payer.publicKey, 1e7)
  );

  /// Create LUT
  const { address } = await createTokenProgramLookupTable(
    connection,
    payer,
    authority,
    additionalTokenMints,
    additionalAccounts
  );

  console.log("Created lookup table:", address.toBase58());
};

main();
