Revoke the mint authority and fix your token's supply

Paste a mint address to see its supply and authorities, then revoke the mint authority with one signature so no more tokens can ever be minted.

How it works

  1. 1

    Paste the mint address

    Enter the token's mint address, or connect your wallet and pick from the tokens where it still holds the mint authority. Supply, decimals and both authorities load without a wallet.

  2. 2

    Check who holds the authority

    The panel shows whether the mint authority is revoked or active and which address holds it. The revoke button only unlocks when your connected wallet is that address.

  3. 3

    Confirm and sign

    Tick the confirmation that this is permanent, review the 0.02 SOL fee, and approve the transaction. The panel reloads the mint and shows the authority as revoked, with a link to the transaction.

What is the mint authority on a Solana token?

Every SPL token has a mint account that records its supply, its decimals and two optional keys. The mint authority is the address allowed to call the MintTo instruction, which creates new tokens out of nothing and adds them to any token account. When you create a token, the mint authority is normally your own wallet, because you need it to mint the initial supply.

As long as that field holds an address, the supply is not fixed: whoever controls the key can mint another billion tokens tomorrow and sell them into the liquidity pool. Holders have no way to prevent it. That is why an active mint authority is the first thing buyers check, and why this page shows it for any token, even without a wallet connected.

How revoking makes a fixed supply token

Revoking, which people also call renouncing the mint authority, is a single SetAuthority instruction with the authority type MintTokens and the new authority set to none. It is the same thing the command spl-token authorize with the mint and --disable flags does. The token program writes an empty value into the mint account, and from that block on every MintTo instruction fails.

The token program has no instruction that sets an authority once it is empty, so the change cannot be reversed by you, by SOLTidy or by anyone else. The supply can only stay the same or shrink when holders burn tokens. Revoking does not touch existing balances, the metadata, the freeze authority or any liquidity pool. The tool works for classic SPL Token and Token-2022 mints and sends the instruction to whichever program owns the mint.

Why RugCheck, DEX screeners and buyers look for it

Token scanners such as RugCheck and the security panels on DexScreener, Birdeye and in wallets flag a token as mintable while the authority is active. Many trading bots skip such tokens outright. For a community token or memecoin there is rarely a good reason to keep the ability to mint, so an active authority reads as either carelessness or an intention to dilute holders.

Revoking it is a cheap, verifiable commitment: anyone can read the mint account and see that the field is empty. It is not a full safety guarantee. A token with fixed supply can still have a freeze authority, a team holding most of the supply or unlocked liquidity. Those are separate checks, and the freeze authority has its own page.

When you should not revoke yet

Mint the entire supply you will ever need first. If the token is designed with emissions, staking rewards that are minted over time, a bridge that mints wrapped tokens, or a stablecoin-style issuer, the mint authority is part of how it works and should instead be held by a multisig or a program. Revoking in those cases breaks the design permanently.

One more dependency: creating a Metaplex metadata account for a token requires the mint authority's signature. If your token has no name and logo yet, which is common for tokens made with the command line, add the metadata first with the Update Metadata tool and revoke afterwards. Editing existing metadata later is not affected, because that uses the separate update authority.

Questions & answers

Can I undo revoking the mint authority?

No. Once the mint authority is set to none, the SPL Token program offers no way to assign a new one. Nobody can restore it, including the original creator and SOLTidy. Make sure the full supply you need has been minted, and that any metadata has been created, before you sign. The panel asks for an explicit confirmation for this reason.

How much does it cost to revoke mint authority on Solana?

This tool charges a flat 0.02 SOL per revoke, included in the same transaction, plus the standard Solana network fee of about 0.000005 SOL. No account is created or closed, so no rent is involved. Looking up any token's mint and freeze authority is free and does not require a wallet.

Is it safe to connect my wallet to revoke the authority?

The tool is non-custodial and runs in your browser. The transaction contains exactly two instructions that your wallet will show you: a SetAuthority on your mint and a 0.02 SOL transfer for the fee. It cannot move your tokens or change anything else. Only the current mint authority can sign it, so the button stays disabled for every other wallet.

How do I check if a Solana token's mint authority is revoked?

Paste the mint address into the panel above. It reads the mint account directly from the chain and shows Revoked or Active with the holding address for both the mint and the freeze authority, together with the current supply. Explorers such as Solscan show the same field, usually labelled Mint Authority, on the token's page.

Does revoking the mint authority affect my liquidity pool or holders?

No. Balances, token accounts, pools and metadata stay exactly as they are. The only change is that the supply can no longer grow. Tokens can still be transferred, traded and burned as before. If anything, scanners will stop showing the mintable warning the next time they refresh the token.

Why is the revoke button disabled for my token?

Either the authority is already revoked, or the connected wallet is not the address that holds it. The panel shows the current authority in full. If it is a different wallet of yours, connect that one. If it is a multisig or a launchpad program, the revoke has to be executed from there, and many launchpads already revoke it at launch.

Is revoking mint authority the same as renouncing ownership?

It is the closest Solana equivalent. SPL tokens have no owner in the Ethereum sense; control is split into the mint authority, the freeze authority and the metadata update authority. Renouncing fully means revoking the first two and, if you want the name and logo locked as well, making the metadata immutable.

Is there a fee?

Revoking a mint authority costs a flat 0.02 SOL SOLTidy fee, paid in the same transaction, plus the usual Solana network fee of about 0.000005 SOL; checking a token's authorities is free.
