Token-2022
The newer Solana token standard that extends the original SPL Token program with features like transfer hooks, metadata extensions, and confidential transfers.
Token-2022 is Solana's second-generation token program (program ID `TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb`). It is backwards-compatible with SPL Token wallets but adds extensions: transfer hooks, metadata pointer, confidential transfers, interest-bearing tokens, and more. Pump.fun and Printr use Token-2022 for newly launched tokens; LaunchLab and Bags still use the original SPL Token standard.
