token-2022-extensions

To create non-transferable tokens on Solana, you implement the Non-Transferable extension within the Token-2022 program. This enables soulbound tokens for memberships or credentials, ensuring they cannot be moved from the holder's wallet.

The correct initialization order requires configuring desired extensions, such as Transfer Fee or Metadata Pointer, before initializing the mint. This sequence ensures proper authority configuration and manages rent implications for the mint's extension state.

Yes, you can attach on-chain metadata directly to a Solana mint without external storage by using the Metadata Pointer extension. It links the mint to its metadata natively within the Token-2022 framework, simplifying data retrieval.

Wallet and DEX support for Token-2022 transfer fees and extension combinations varies. You must assess cross-ecosystem compatibility and verify extension state on a Solana testnet to ensure interoperability before launching.

To monetize Solana token transfers, you configure the Transfer Fee extension during mint design. This allows you to set configurable fees on transfers and manage the fee withdrawal flow for the designated authority.
