Can update authority be restored later?

No. This action is intended to be permanent. After revoke, this authority can no longer edit token metadata fields like name, symbol, image, and links.

Should I update metadata before revoking authority?

Yes, in most cases. Teams usually use Update Metadata to finalize branding and links first, then revoke update authority as the last metadata control step.

Why do I get a metadata missing error?

That usually means the mint has no metadata account yet, or the mint address is incorrect. Verify the token mint address and try again.

Is revoke update authority the same as make immutable?

Not exactly. This tool focuses on metadata update authority. Make Immutable can combine multiple authority lock actions such as mint, freeze, and metadata depending on token state.

Does this change existing token balances or supply?

No. It only affects metadata edit permissions. Existing balances and supply stay the same after this transaction.

Revoke Update Authority

Connect wallet in top bar

Use this tool to revoke update authority from Solana token metadata in one transaction. Connect the correct wallet, verify metadata account status, and lock metadata edits safely.

Token Mint Address (CA)

Status:

Metadata Missing / Invalid

After revoke, token metadata can no longer be edited from this authority.

Platform Fee

0.1 SOL

What This Tool Does

This page helps you revoke update authority from an SPL token metadata account with one direct action. Paste the mint address, verify metadata account availability, and submit the transaction. Use it when metadata updates are complete and you want a permanent lock.

How It Works

Enter the token mint address and let the tool find the metadata account. If metadata exists, you can submit one transaction that sets new update authority to null. After confirmation, this authority can no longer change name, symbol, image, or linked metadata fields.

How to Lock Token Metadata on Solana

Step 1 — Paste the Token Mint Address

Enter your SPL token's contract address (CA) into the input field. The tool checks whether a metadata account exists for that mint and identifies the wallet that currently holds the ability to modify token name, symbol, image, and linked fields.

Step 2 — Verify Wallet and Metadata Status

Connect the wallet that controls metadata editing. The status field shows whether the connected wallet is valid, whether a different wallet holds the permission, or whether the metadata account is missing or already locked. If the status shows "Metadata Missing / Invalid", you cannot proceed.

Step 3 — Confirm and Submit

Review the warning — this action permanently locks all token metadata fields. After confirmation, no wallet can change the token name, symbol, description, or social links. The tool sends a single on-chain instruction to the Solana network. Platform fee is 0.1 SOL, shown before submission.

Why Use This Tool

Teams often revoke update authority after final branding and links are published. J Tools keeps this step compact with status checks, a clear warning, and a single revoke action. That makes metadata lock decisions easier to execute without dashboard complexity.

What Is Metadata Authority on Solana?

Every SPL token on Solana can have a designated wallet that controls the ability to modify token metadata — including the token name, symbol, description, image, and social links. While this permission is active, the designated wallet can change how the token appears across wallets, explorers, and DEX listings at any time.

Removing this permission means no wallet can edit those fields going forward. Most projects finalize their branding and then permanently lock metadata before listing on DEXs, because the ability to change a token's identity after launch reduces holder trust. Once locked, this action cannot be reversed.

When to Use This Page

This page is designed for one final control step: removing metadata update authority from a live Solana token. J Tools verifies metadata account presence first, then lets the authority wallet submit the revoke transaction clearly. Once confirmed, metadata edits from this authority stop permanently, so you should complete all final metadata updates before you continue.

If you still need to edit branding, open Update Metadata first. If you are starting from scratch instead of locking an existing mint, begin with Token Creator.

Key Features

Mint address input — Paste the token mint address to start the metadata authority check.
Metadata status check — Confirm whether the metadata account exists before submission.
Clear warning — Review the irreversible metadata lock warning before you sign.
One-click action — Submit the revoke update authority transaction from one focused button.
Wallet connection — Use a wallet or private key to sign with the current authority.
Transparent pricing — Platform fee is 0.1 SOL before transaction submission.

What to Do After Locking Metadata

Once token metadata is permanently locked, you may want to continue with related trust and authority actions:

Revoke mint authority to lock the token supply permanently.
Revoke freeze authority to remove account freezing control.
Make your token immutable by removing all remaining authorities in one step.
Update metadata to finalize logo, description, or social links before revoking this authority.
Create a liquidity pool on Raydium, Meteora, or Orca now that all trust settings are locked.
