Update Metadata

Update Metadata edits the on-chain metadata of an existing Solana token: its name, symbol, description, logo, and social links. You sign once from the wallet that holds the update authority, and the token contract address, supply, and balances all stay the same.

Network fee, rent and transaction value are separate.

When this tool fits

#when-this-tool-fits

• You hold the update authority and need to fix or refresh your token’s branding after launch.
• You want to swap a logo, correct a name or symbol typo, or add a website, Twitter, or Telegram link.
• You just want to inspect a token’s current on-chain metadata. The Load step reads it back so you can see what is set before you touch anything.

Before you start

#before-you-start

• A connected wallet that holds the token’s update authority (how to connect), either the header wallet or a Local Signer key. The tool reads the metadata account before it builds the transaction and stops if this wallet is not the current update authority.
• The token’s mint address (contract address). Pick it with the built-in token selector. The token needs a Metaplex metadata account, because that is the account this tool writes to.
• Enough SOL for the network fee and the platform fee. The Update Metadata button stays disabled while the balance is short.
• A logo ready to upload if you plan to change it (PNG, JPG, GIF, or WEBP, up to 1 MB).

How to use it

#how-to-use-it

1. Paste the mint and load current metadata

   Paste the token’s contract address into the mint field, or pick it from the selector. Click Load to read the current name, symbol, description, image, and social links. Loading needs no wallet.

2. Edit only the fields you need

   Change the name, symbol, or description, upload a new logo, and update the website, Twitter, or Telegram links. Every field is written again on update, so start from the loaded values and change only what needs changing.

3. Connect the authority wallet and submit

   Connect the wallet that holds the update authority, check the platform fee next to the button, and click Update Metadata. Approve the single transaction in your wallet.

Key settings

#key-settings

• Token mint address: The token whose metadata you are editing. Required. Pick it with the token selector.
• Name: The token name shown in wallets and explorers. The Metaplex account holds 32 characters. The form does not cut you off: a longer name of up to 64 characters is rejected only when you sign, and anything past 64 is refused when the metadata file is saved. Left empty, the name is written as “Unknown”.
• Symbol: The ticker. Force-uppercased, up to 10 characters. Left empty, it is written as “UNK”.
• Description: A short blurb written into the off-chain metadata JSON. Up to 2000 characters.
• Logo / image: Upload a new logo, or keep the image that Load brought in (Use Current switches back to it after you pick a file). An uploaded file is copied to J Tools asset storage before the update, and the on-chain record points at the copy. The loaded image is copied the same way, and if that copy fails, its original link is kept. Stored files are addressed by hash, so uploading the same image again returns the same URL.
• Website: Your project’s site. The field turns red unless it is a full public http or https address. It does not block the update: a link without http:// or https:// gets https:// added, and a placeholder or unusable link is left out.
• Twitter: Your X / Twitter profile. Checked the same way as the website.
• Telegram: Your Telegram group or channel. Checked the same way as the website.

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	0.2 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.

FAQ

#faq

Can I still edit metadata after I revoke the update authority? No.

No. Once you revoke the update authority, the metadata is frozen for good. Get the name, symbol, and image right here first, then revoke it with Revoke Update Authority or Make Immutable.

How long until wallets show the new branding? The on-chain record updates the moment your transaction confirms.

The on-chain record updates the moment your transaction confirms. Wallets, explorers, and price aggregators cache metadata, so the new name and logo can take from minutes to a few hours to appear everywhere.

Before you sign

#before-you-sign

Check the live summary before signing. The app is the current source of truth for amount, fee and route.

Common issues

#common-issues

• This token has no metadata account. The mint has no Metaplex metadata account, so there is nothing this tool can edit, and it stops before anything is signed. A Token-2022 token that keeps its metadata inside the mint, the way Token-2022 Creator builds it, lands here too, even when Load shows its name and logo.
• You are not the update authority. The connected wallet does not control this token’s update authority. The tool checks this before signing and stops. Connect the wallet that does.
• Editing the wrong field. Skipping the Load step and typing into an empty form overwrites values you meant to keep: an empty name becomes “Unknown”, an empty symbol “UNK”, and empty links are dropped. Load first, then change only what you need.
• Metadata is locked. The metadata account is immutable, usually because Make Immutable has already run on this mint. The tool stops at the pre-flight check and nothing is signed.

Practical tips

#practical-tips

• Keep the logo small. Heavier files slow the upload and gain you nothing at the size wallets and explorers actually render.
• Keep your socials valid. Broken or private links get flagged by some explorers. Use full public http or https URLs.

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.
