🛡️ How these tools work

Every tool builds a Solana transaction that your own wallet signs. MemeMintr never holds your keys, your tokens or your SOL, and can't move anything without your approval.

While metadata is mutable, the update authority can change the token's name, symbol and image at any time. Buyers and scanners treat that as a risk.

Making the token immutable flips the Metaplex metadata to non-mutable. After that, nobody can edit it again.

How it works

  1. Connect the wallet that holds the update authority.
  2. Paste the token mint address and click Load.
  3. Open Make Token Immutable and confirm.
  4. Sign the transaction.

FAQ

Can I update metadata after making it immutable?

No. Finish any metadata changes first, then lock it.

How much does it cost?

0.08 SOL plus the Solana network fee (a fraction of a cent).
