Light Token SDK

The base library to use Light Token Accounts, Light Mints, and compressed token accounts.

Light Token Accounts

• are on Solana devnet.
• are Solana accounts.
• can hold Light Mint and SPL Mint tokens.
• cost 17,288 lamports to create with 24 hours rent.
• are rentfree:
  • rent exemption is sponsored by the protocol.
  • rent is 388 lamports per rent epoch (1.5 hours).
  • once the account's lamports balance is insufficient, it is compressed to a compressed token account.
  • compressed tokens can be decompressed to a Light Token account.
  • configurable lamports per write (eg transfer) keep the Light Token account perpetually funded when used. So you don't have to worry about funding rent.

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.

Light Mints

• are on Solana devnet.
• are Compressed accounts.
• cost 15,000 lamports to create.
• support TokenMetadata.
