What is Token-2022?
Token-2022 (also known as Token Extensions Program) is the next generation of the SPL Token standard on Solana. Built-in extensions that you normally would need a smart contract for.
Available extensions
1. Transfer Fee
Automatically charge a percentage on every transfer. Useful for: revenue sharing, deflationary mechanisms.
2. Interest Bearing
The token supply grows automatically over time. Useful for: yield tokens, staking tokens.
3. Non-Transferable (Soulbound)
Tokens that cannot be transferred between wallets. Useful for: membership tokens, achievement badges.
4. Permanent Delegate
An address with full control over all token accounts. Useful for: programmable compliance.
How to enable via SPLCreator
In step 4 ("Advanced options") of the wizard you can enable extensions. Extensions must be set at creation time.
