How to Update Metaplex Token Metadata?

Solscan has switched to using Metaplex Metadata as the newest token standard across the network.

When you create a token, you want to make sure that the token shows up in user's wallets with a name, ticker, and image. Solana uses the Token Metadata Program from Metaplex to achieve this.

The metadata account address is derived from the mint account. The metadata field requires a JSON file to be populated with at least the following:

{ 
"name": "Coin name",
"symbol": "Symbol",
"image": "Image link"
}

Some background for users and developers:

The concept of tokens on Solana is not binary anymore as there are different types of tokens on Solana than simply “fungible” and “non-fungible” tokens.

The Metaplex’s token standard field can have the following values:

• NonFungible: A non-fungible token with a Master Edition.
• FungibleAsset: A token with metadata that can also have attributes, sometimes called Semi-Fungible.
• Fungible: A token with simple metadata.
• NonFungibleEdition: A non-fungible token with an Edition account (printed from a Master edition).

This section serves two goals: Assist developers with the process of creating new Token using Metaplex Token Standard: Also help them update “legacy tokens” metadata with the Metaplex standard.

The JSON schema for the tokens according to the Metaplex Fungible Token Metadata Standard includes the following:

How to Update Token Information on Solscan

To update a Solana token metadata, you must be the token deployer or have access to the wallet that creates the token and holds the Update Authority.

When you make the changes in the token's metadata, your token's page on Solscan will be automatically updated to reflect the new information.

However, Solscan provides support for token projects that wish to update their token information on Solscan website (under specific cases).

This assistance will only help you to update the information on Solscan UI, not the metadata.

To request support for updating token information, simply fill out the form UPDATE TOKEN INFORMATION ON SOLSCAN with accurate details and await our review.

It’s essential to ensure that the request needs to contain proof of ownership from the token owner through on-chain data. Without this information, your request will most likely be rejected.

A few other rules to remember:

• This form is exclusively developed for projects that have no access to updating the token metadata (such as community takeover, or token with immutable update authority). If your token does not fall into this category, please do not fill out this form.
• Ensure that all put-down information is accurate, and links are valid and accessible.
• Avoid submitting duplicate entries, this will only add to the backlog and cause longer waiting times.
