Make Solana token metadata immutable

Permanently lock a token’s name, symbol, and logo so nobody — including you — can ever edit them again. This action is irreversible.

01

Select token

This tool permanently locks a Solana token’s metadata — its name, symbol, and logo — so nobody can ever edit it again. Not you, not Dexmint, not whoever holds the wallet in five years. It is a one-signature trust signal: anyone checking your token on an explorer sees the metadata is frozen exactly as it is today, which is something careful buyers look for before they put money in.

The lock only becomes real once you approve it from your own wallet — until that signature, nothing changes.

How to make Solana token metadata immutable

  1. Connect your wallet

    Connect the wallet that holds the token’s update authority — usually the one that created the token. No other wallet can lock the metadata.

  2. Select the token

    Pick the token from your wallet list or paste its mint address. The tool reads its live on-chain state and shows the supply, decimals, and authorities so you can confirm it’s the right one.

  3. Make your final edits first

    This is your last chance to change anything. If the name, symbol, or logo needs a fix, do it with the Update Metadata tool before you continue — after this transaction, editing is closed forever.

  4. Check the eligibility notice

    The tool tells you up front if the metadata is already immutable or the connected wallet isn’t the update authority, so you never pay for a transaction that would fail.

  5. Review the fee and sign

    A flat fee is shown in the fee ledger before you approve anything, and coupon codes apply there too. Read the warning, sign in your wallet, and you get an explorer link once the change confirms.

What immutable metadata means on Solana

Every Solana token has a metadata account storing its name, symbol, and a link to its logo. While that account is mutable, the update authority can rewrite any of it at any time — a token could quietly change its name or image after people have bought it. This tool switches that mutable flag off, permanently. Explorers then show the metadata as immutable, and nobody can turn it back on.

Note what it does not touch: supply and freezing are separate. Locking the metadata doesn’t revoke the mint or freeze authority — those have their own tools, linked below.

When to make your token immutable

The usual moment is around launch, once your branding is final. Many rug-check tools and DEX screeners flag mutable metadata as a risk, so locking it removes one reason for buyers to hesitate — especially combined with revoking the mint authority.

Hold off if there’s any chance you’ll rebrand, fix a typo, or swap the logo. Double-check the spelling of your name and symbol and how the logo looks in a wallet first. If you want a free dry run, do the whole flow on Devnet — it costs nothing and behaves identically.

Frequently asked questions

Can I undo making my token immutable?

No. This is permanent and irreversible — neither you, Dexmint, nor anyone else can ever edit the name, symbol, or logo again. That finality is exactly what makes it a trust signal.

Does this affect my token supply or freeze authority?

No. It only locks the metadata. The mint authority (creating more supply) and freeze authority (freezing holder accounts) are separate, each with its own revoke tool.

Is there a charge for locking metadata?

A single flat fee, itemised with any coupon in the fee ledger before you approve, plus a tiny Solana network fee. If you never sign, nothing is charged — and nothing is locked.

Who is allowed to make a token immutable?

Only the wallet holding the token’s update authority — typically the creator. The tool checks this on-chain when you select the token and tells you if the wallet doesn’t qualify or the metadata is already locked.

Can the token still be traded and sent afterwards?

Yes, completely. Holders can buy, sell, and transfer it exactly as before. The only thing that closes is the ability to edit the metadata.
