The Token Extensions Program enhances the Solana Token Program with additional functionality.
- Token Extensions Program ID:
TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb - Original Token Program ID:
TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA
Use the Solana Tool Suite CLI to create tokens with specific extensions. Below are the available extensions and their respective CLI flags:
| Extension | CLI Flag |
|---|---|
| Mint Close Authority | --enable-close |
| Transfer Fees | --transfer-fee <basis points> <max fee> |
| Non-Transferable | --enable-non-transferable |
| Interest-Bearing | --interest-rate <rate> |
| Permanent Delegate | --enable-permanent-delegate |
| Transfer Hook | --transfer-hook <programID> |
| Metadata | --enable-metadata |
| Metadata Pointer | --metadata-address <accountId> |
| Confidential Transfers | --enable-confidential-transfers auto |
| Extension | CLI Flag |
|---|---|
| Immutable Owner | Included by default |
| Required Memo on Transfer | --enable-required-transfer-memos |
| CPI Guard | --enable-cpi-guard |
| Default Account State | --default-account-state <state> |
To create a token with Interest Rate and Metadata extensions, use:
spl-token --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb \
create-token --interest-rate 5 --enable-metadata- Extensions cannot be added after the token mint is created.
Certain combinations either conflict or are impractical:
- Non-transferable + (Transfer Hooks, Transfer Fees, Confidential Transfers)
- Confidential Transfers + Fees (until version 1.18)
- Confidential Transfers + Transfer Hooks (limited to source/destination accounts, without acting on transferred amounts)
- Confidential Transfers + Permanent Delegate
Developers can replace standard transfer operations with custom logic using the Transfer Hook Extension.
