Light Token SDK
The base library to use Light Token Accounts, and Light Mints.
Light Token Accounts
- are on Solana devnet.
- are Solana accounts.
- are functionally equivalent to SPL token accounts.
- can hold tokens of Light, SPL and Token 2022 mints.
- cost 17,288 lamports to create with 24 hours rent.
- are rentfree:
- rent exemption is sponsored by the token program.
- rent is 388 lamports per rent epoch (1.5 hours).
- once the account's lamports balance is insufficient, it is auto-compressed to a compressed token account.
- the accounts state is cryptographically preserved on the Solana ledger.
- compressed tokens can be loaded 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.
- users load a compressed account into a light account in-flight when using the account again.
Light Mints
- are on Solana devnet.
- are Compressed accounts.
- support
TokenMetadata. - have the same rent-config as light token accounts
