Token-2022 Standard
SolFoundry supports both Token-2022 (recommended, with on-chain metadata) and Classic SPL tokens. Token-2022 adds metadata extensions and future-proof architecture to the classic SPL token standard.
Why Token-2022
Token-2022 (also called Token Extensions) is Solana's latest token program. It adds native support for features that previously required external programs or complex workarounds.
- On-chain metadata — token name, symbol, and image URI are stored directly in the mint account, not in a separate Metaplex account
- Transfer hooks — custom logic that runs on every token transfer (available for future extensions)
- Future extensions — confidential transfers, transfer fees, permanent delegate, and more
What this means for your token
- Your token metadata is part of the mint itself — no separate metadata account to manage or pay for
- Explorers (Solscan, Solana Explorer) read the metadata directly from the mint
- The metadata update authority can be revoked at launch, making name, symbol, and image truly permanent
- Anti-sniper protection is handled at the pool level via Meteora fee scheduler (no token-level hooks needed)
Compatibility
- Token-2022 tokens are supported by Phantom, Solflare, and all major Solana wallets
- Jupiter, Raydium, and other DEXes support Token-2022 tokens
- Solscan and Solana Explorer display Token-2022 metadata natively
