Toolkit to Index Light Token Accounts

Light token accounts follow the same layout as SPL-token accounts, so you can reuse your existing parsers.

When a market becomes inactive, its token accounts and related PDAs will be compressed - their state is committed and effectively frozen until a client decompresses it. While compressed, pure on-chain lookups will return uninitialized.

Your indexer should keep tracking, quoting, and routing markets even if the on-chain account shows is_initialized: false, is_compressed: true. To trade a cold market, the first client must prepend an idempotent decompress “warm up” instruction.

Setup

npm install @lightprotocol/compressed-token@alpha \
            @lightprotocol/stateless.js@alpha

1. Load Compressed Tokens to Hot Balance

   Action

   import { Keypair } from "@solana/web3.js";
   import { createRpc, bn } from "@lightprotocol/stateless.js";
   import {
     createMint,
     mintTo,
     loadAta,
     getAssociatedTokenAddressInterface,
   } from "@lightprotocol/compressed-token";
   
   async function main() {
     const rpc = createRpc();
     const payer = Keypair.generate();
     await rpc.requestAirdrop(payer.publicKey, 10e9);
   
     const owner = Keypair.generate();
     await rpc.requestAirdrop(owner.publicKey, 1e9);
   
     const mintAuthority = Keypair.generate();
     const mintKeypair = Keypair.generate();
     const { mint } = await createMint(
       rpc,
       payer,
       mintAuthority.publicKey,
       9,
       mintKeypair,
     );
   
     await mintTo(rpc, payer, mint, owner.publicKey, mintAuthority, bn(1000));
   
     // Get c-token ATA address
     const ctokenAta = getAssociatedTokenAddressInterface(mint, owner.publicKey);
   
     // Load compressed tokens to hot balance
     // Creates ATA if needed, returns null if nothing to load
     const signature = await loadAta(rpc, ctokenAta, owner, mint, payer);
   
     if (signature) {
       console.log("Loaded tokens to hot balance");
       console.log("Transaction:", signature);
     } else {
       console.log("Nothing to load");
     }
   }
   
   main().catch(console.error);
