Light Compressed Token SDK

Low-level SDK for compressed token operations on Light Protocol.

This crate provides the core building blocks for working with compressed token accounts, including instruction builders for transfers, mints, and compress/decompress operations.

Compressed Token Accounts

are on Solana mainnet.
are compressed accounts.
can hold Light Mint and SPL Mint tokens.
cost 5,000 lamports to create.
are well suited for airdrops and reward distribution.

Difference to Light-Token:

light-token: Solana account that holds token balances of light-mints, SPL or Token 22 mints. Compressed token: Compressed account storing token data. Rent-free, for storage and distribution.

Features

v1 - Enable v1 compressed token support
anchor - Enable Anchor framework integration
