Revoke Mint Authority Free
Permanently disable the ability to mint new supply for any SPL token you control. No platform fee — only the Solana network fee.
Connect your wallet to look up and revoke mint authority.
What is mint authority?
Every SPL token mint account on Solana has an optional mint authority — the address permitted to create new tokens. As long as mint authority is set, that address can increase the total supply at will, which can dilute existing holders. Revoking it sets the authority to null, permanently disabling further minting.
Benefits of revoking mint authority
A fixed, provably capped supply is one of the strongest trust signals in the Solana ecosystem. Traders and holders routinely check whether mint authority has been revoked before investing in a new token — doing so signals the team cannot inflate supply after launch.
Risks to consider
Revocation is permanent and cannot be undone. Only revoke mint authority once your token's total supply is finalized — you will never be able to mint additional tokens afterward, even for legitimate purposes like community rewards.
Frequently asked questions
What is mint authority?
Mint authority is the on-chain permission that allows an account to create (mint) additional supply of an SPL token. Whoever holds it can increase the token's circulating supply at any time.
Why should I revoke mint authority?
Revoking mint authority permanently proves to your holders that the total supply is fixed and can never be inflated by the team or anyone else. It's one of the clearest trust signals a token project can send.
Is revoking mint authority reversible?
No. Once mint authority is set to null on-chain, it can never be restored. Make sure your total supply is exactly what you want before revoking.
Does revoking mint authority cost anything?
No platform fee. You only pay the standard Solana network fee for the transaction.
