Overview

Compressed tokens provide full SPL token functionality without per-account rent cost.

Creation	Regular SPL Token	Compressed Token	Cost Reduction
100 Token Accounts	~ 0.2 SOL	~ 0.00004 SOL	5000x

Compressed token accounts store information about an individual’s ownership of a specific token (mint). Different from regular token accounts, they don’t require an Associated Token Account (ATA) per token holder.

For example, this simplifies token distribution, since you don’t need to allocate a token account per recipient.

Compressed Tokens at a Glance

Rent-free tokens

Create token accounts without upfront rent exempt balance.

SPL Compatibility

Compatible with SPL tokens and Solana programs.

Wallet Support

Supported by leading wallets including Phantom and Backpack.

Start building

Developing with compressed tokens works similar SPL tokens and involves minimal setup:

1. Install dependencies

   npm

   npm install --save-dev typescript tsx @types/node && \
   npm install --save \
       @lightprotocol/stateless.js \
       @lightprotocol/compressed-token \
       @solana/web3.js \
       @solana/spl-token
   
2. Set up your developer environment

   Setup Developer Environment

   By default, all guides use Localnet.

   # Install the development CLI
   npm install @lightprotocol/zk-compression-cli
   

   # Start a local test validator
   light test-validator
   
   ## ensure you have the Solana CLI accessible in your system PATH
   

   // createRpc() defaults to local test validator endpoints
   import {
     Rpc,
     createRpc,
   } from "@lightprotocol/stateless.js";
   
   const connection: Rpc = createRpc();
   
   async function main() {
     let slot = await connection.getSlot();
     console.log(slot);
   
     let health = await connection.getIndexerHealth(slot);
     console.log(health);
     // "Ok"
   }
   
   main();
   

   Alternative: Using Devnet

   Replace <your-api-key> with your actual API key. Get your API key here, if you don’t have one yet.

   import { createRpc } from "@lightprotocol/stateless.js";
   
   // Helius exposes Solana and Photon RPC endpoints through a single URL
   const RPC_ENDPOINT = "https://devnet.helius-rpc.com?api-key=<your_api_key>";
   const connection = createRpc(RPC_ENDPOINT, RPC_ENDPOINT, RPC_ENDPOINT);
   
   console.log("Connection created!");
   console.log("RPC Endpoint:", RPC_ENDPOINT);
