What does revoking mint authority do?

It permanently fixes the token supply. Once the mint authority is null, no address — including you — can ever mint more of the token. Buyers look for this as the baseline proof that the supply cannot be inflated.

Can I undo revoking the mint authority?

No. Setting the mint authority to null is one-way and irreversible. There is no way to restore a mint authority once it has been removed, so only revoke when you are sure the supply is final.

Does revoking mint authority make my token safe?

It removes one specific risk — supply inflation — but not all of them. The freeze authority can still exist, and if you hold the liquidity you can still pull it. Revoke mint authority, revoke freeze authority, and lock or burn liquidity are three separate protections; a serious launch does all three.

Revoke mint authority on Solana

Permanently remove the mint authority from your SPL token so no more can ever be minted and the supply is fixed forever. Paste your mint address, connect your wallet, and sign a single transaction — non-custodial from start to finish.

What revoking mint authority does

Every SPL token has a mint authority: the single address allowed to create new units of that token. While it exists, the holder can inflate the supply at will, which is why an active mint authority is a red flag to buyers and to token scanners. Revoking it issues a SetAuthority instruction that sets the mint authority to null, permanently. After that, the supply on-chain is the final supply — nobody can ever mint more.

This tool does exactly one thing: it revokes the mint authority on the mint address you paste, in a single transaction your own wallet signs. It never takes custody of the token, the mint, or any other authority. It is the graphical equivalent of running spl-token authorize <MINT> mint --disable yourself.

When to revoke, and what it does not cover

Revoke the mint authority once your supply is genuinely final — after any presale mint, airdrop allocation, or LP seeding is done, because you cannot mint again afterward. Fixing the supply is only one of three separate trust signals:

Mint authority — controls whether more supply can be created. This tool handles it.
Freeze authority — controls whether holders can be frozen. Revoke it with the revoke freeze authority tool.
Liquidity — a fixed supply means nothing if you can still pull the pool. Lock or burn your liquidity too.

This is permanent. A revoked mint authority can never be restored. Make sure every token you ever intend to mint has been minted before you sign.

Revoke mint authority: FAQ

How do I revoke mint authority on Solana?

Paste your token mint address, connect the wallet that holds the mint authority, and sign one transaction. The tool issues a SetAuthority instruction that sets the mint authority to null so no more tokens can ever be created.

Can I undo it?

No. Setting the mint authority to null is one-way and irreversible — there is no way to restore it afterward.

Does this make my token rug-proof?

No. It stops supply inflation only. You still need to revoke the freeze authority and lock or burn the liquidity for a launch to be meaningfully rug-resistant.

What does it cost?

A small service fee plus the Solana network fee, charged only when the revoke succeeds. We don't keep the fee — see how this tool's fees benefit compassSOL stakers.
