Revoke Update Authority

Revoke Update Authority permanently locks your token’s Metaplex metadata in a single transaction by flipping its isMutable flag to false. Once it confirms, no wallet can ever edit the name, the symbol, or the metadata link again, and the link is what carries the image, description, and social links.

Platform fee

0.1 SOL

Network fee, rent and transaction value are separate.

Before you start

#before-you-start

• A connected wallet (how to connect) that currently holds the token’s metadata update authority. This is the wallet that signs. If it is not the update authority, the tool blocks the action before you sign.
• The token’s mint address (CA). Pick it with the built-in token selector.
• A token that already has a Metaplex metadata account. The status check must show Metadata Found before you can proceed.
• Enough SOL in that wallet for the network fee and the platform fee.

How to use it

#how-to-use-it

1. Paste the token mint address

   Paste the mint address (CA) or pick the token from the selector. J Tools derives the metadata account for the mint, reads it on-chain, and shows its address next to a status badge.

2. Verify wallet and metadata status

   Connect the wallet that holds the update authority (the header wallet or a Local Signer key through the Wallet Source selector). Go ahead only when the badge reads Metadata Found and the irreversible-action notice shows. No Metadata, Already Revoked, or Different Wallet means this wallet cannot lock it, and the button is blocked.

3. Confirm and submit the transaction

   Click Revoke Update Authority and approve in your wallet. The page waits for confirmation, then reads the metadata account again to check that the lock took effect.

Key settings

#key-settings

• Token Mint Address (CA): The token whose metadata will be locked, entered through the built-in token selector. As you type, J Tools derives the Metaplex metadata account and shows whether it was found.
• Wallet Source: Picks which wallet signs, either your connected header wallet or a Local Signer key through the Wallet Source selector. Whichever you choose must currently be the update authority on the mint’s metadata.
• Metadata status badge: A read-only indicator. Metadata Found means the account exists and nothing blocks the lock. No Metadata means there is no metadata account, Already Revoked means it is already immutable, and Different Wallet means another wallet is the update authority. Metadata Missing / Invalid shows when the address could not be read, and Loading while the read runs. It gates the action: you can only revoke when it reads Metadata Found.
• Revoke Update Authority button: Builds and submits the transaction that locks the metadata by setting isMutable to false and attaches the platform fee. This is the irreversible step.

Fees and costs

#fees-and-costs

Caution

About fees. Every action has two costs: the Solana network fee paid to validators, and the J Tools platform fee. The platform fee always shows in the app before you confirm, and nothing is charged until you sign. Fees can change over time, so trust the in-app summary rather than a number you saw once.

Cost	Amount
J Tools platform fee	0.1 SOL
Solana network fee	Paid to validators during the transaction; shown in the live summary.
Rent and transaction value	Shown separately when required; not part of the platform fee.

When to use it (and when not to)

#when-to-use-it-and-when-not-to

• You have finished branding the token (name, symbol, image, links) and want to lock it before listing.
• You want to signal to holders that the token identity cannot be silently changed after launch.
• You hold the metadata update authority for an existing SPL mint and want to retire it for good.
• You still might edit the metadata. Once revoked there is no way back. Get everything right with Update Metadata first.
• You want to fix supply or remove freezing instead. To fix supply only, use Revoke Mint; to remove account freezing, use Revoke Freeze.
• You want to remove every authority at once (mint, freeze, and update). Use Make Immutable for a single full lock.

Before you sign

#before-you-sign

Irreversible: This action cannot be reversed on-chain. Double-check the mint and authority before signing.

Common issues

#common-issues

• Metadata account was not found. The badge reads No Metadata: the mint has no Metaplex metadata account, or the address is wrong. Double-check the CA. A token with no metadata account has no update authority to revoke here. A Token-2022 token that keeps its metadata inside the mint, as Token-2022 Creator builds it, is in this group.
• Wrong wallet. The badge reads Different Wallet: the connected wallet does not hold the update authority. Connect the wallet that does, then retry.
• Metadata is already immutable. The isMutable flag is already false, so there is nothing left to lock. The badge reads Already Revoked, the run is blocked before signing, and nothing is charged.
• Lock did not verify. After the transaction confirms, the tool re-reads the metadata account. If isMutable is still true it reports the revoke as not applied rather than treating a no-op as a success.
• Revoked too early. If you locked the metadata before finishing the branding, there is no recovery. The metadata is now permanent. Edit before you revoke, never after.

Practical tips

#practical-tips

• Order does not matter across the three. Revoking update, mint, and freeze are independent. You can do them in any order, or in one batch, without affecting each other.
• Verify after. Open the token’s metadata on Solscan and confirm it shows Mutable: No, so you have proof for holders and listing reviewers. The update authority address still appears on the account; that is expected, and it can no longer change anything.

Note

About wallet warnings. Some tools bundle several instructions into one transaction, for example creating a token and its metadata together. Phantom can show a caution banner for these transactions, and where the tool tells you to expect one, it does not mean something is wrong. Read what you are signing, then approve if it matches what you set up. If a warning appears that the tool did not mention, decline it and tell support.

Tip

J Tools is non-custodial. We never store your wallet’s private keys and never ask for your seed phrase. Every transaction you approve in a connected wallet is signed inside that wallet, and its key never reaches our servers. A few multi-wallet tools do let you paste private keys for throwaway hot wallets, which stay in your browser tab and sign there. Holder Booster is the one tool that hands a key to our worker: the fresh distributor wallet it creates for each run, sent encrypted. Never paste a key tied to long-term holdings, and if a page ever asks for your seed phrase, stop and close it.
