GitHub - Lightprotocol/examples-light-token: Examples for Stablecoin Payments, Agent Commerce, DeFi and Basics on Solana using Light Token and ZK Compression.

Light Token and ZK Compression allows you to build scalable Solana applications with rent-free token and mint accounts and PDA's.

Metric	Light	Standard Solana
Mint Account	~0.000091 SOL	~0.0015 SOL
Token Account	~0.000017 SOL	~0.0029 SOL
PDA (100-byte)	~0.000012 SOL	~0.0016 SOL

All light mint and token accounts are on-chain accounts like SPL, but the light token program sponsors the rent-exemption cost for you.
Light-token accounts can hold balances from any light, SPL, or Token-2022 mint.
Light-mint accounts represent a unique mint and optionally can store token-metadata. Functionally equivalent to SPL mints.
Light-PDAs are Solana PDAs with sponsored rent-exemption and can be implemented with minimal code changes to your existing Solana program. Your program logic stays mostly untouched, which keeps audit overhead minimal.

Macros

	Description
counter	Create, increment and close counter PDA with sponsored rent-exemption
create-associated-token-account	Create associated light-token account
create-mint	Create light-token mint
create-token-account	Create light-token account

Instructions

The instructions use pure CPI calls which you can combine with existing and / or light macros. For existing programs, you can replace spl_token with light_token instructions as you need. The API is a superset of SPL-token so switching is straightforward.
