This program is a custom token implementation on Solana built with Anchor.
It provides token functionality similar to the SPL Token Program but with customizable business logic such as account freezing, custom delegation rules, and controlled burning.
- Minting – Create and distribute tokens from a mint account.
- Transfers – Send tokens between accounts with ownership and freeze checks.
- Delegation – Approve a delegate to spend tokens on your behalf.
- Revoke Delegate – Remove a delegate’s spending authority.
- Freezing – Temporarily lock a token account so no transfers can occur.
- Burning – Permanently destroy tokens, reducing the total supply.
- Closing Accounts – Burn remaining tokens and reclaim rent before closing.
