How to check Solana Token-2022 extensions
Token-2022 mints can carry extra controls such as a permanent delegate, a transfer hook or a non-transferable setting. Paste the mint into Token Check to read the token program and any flagged extensions. The lookup is read-only.
Confirm the token program first
Open Token Check at /tools?tab=check&mint= followed by the mint. Read whether the mint is on the classic SPL Token program or Token-2022, and note the UTC scan time. Extensions apply to Token-2022 mints. A familiar name or ticker does not tell you which program it uses.
Read the extensions that Token Check flags
A permanent delegate can move holders’ tokens. A transfer hook attaches a program that can run additional logic on transfers. A non-transferable, or soulbound, setting means the token cannot be sent in the ordinary way. Each of these is a separate control; one can be present without the others.
Do not stop at extensions alone
Still read mint authority, freeze authority and whether metadata is mutable. Revoking mint authority does not remove a permanent delegate, and a clean-looking authority row does not audit every Token-2022 extension. If a field is unavailable, treat it as unknown, not as absent.
This is an inspection, not a complete audit
Token Check reports the extensions it flags from public mint data. Other Token-2022 extensions may exist and need independent review, including in a Solana explorer. Never enter a seed phrase or sign a transaction merely to inspect a public mint. Educational content, not financial advice.
Frequently asked questions
Does revoked mint authority remove a permanent delegate?
No. These are separate controls. A revoked mint authority does not remove a permanent delegate.
Do I need a wallet to inspect Token-2022 extensions?
No. Token Check reads public mint data and does not ask you to sign.
