Crate light_compressed_token_sdk 

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 for most token use cases (launchpads, DeFi, payments). Mint and token accounts with sponsored rent-exemption. Compressed token: Compressed account storing token data. Rent-free, for storage and distribution. Prefer Light Token for other purposes. Used by Light Token under the hood for rent-free storage of inactive Light Tokens.

Features

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