What is mutable metadata (update authority)?
Also called: Update authority, Metadata can be changed
A token whose name, symbol, image or links can still be changed, because the metadata's update authority has not been removed.
A Solana token's name, ticker and logo do not live in the mint itself. They live in a separate metadata account (usually Metaplex metadata, or the metadata extension on Token-2022), which has its own update authority. While that authority exists and the metadata is marked mutable, the holder of the key can change what wallets and explorers display.
Many established tokens keep metadata mutable so they can update a logo or website. That is not a problem in itself. The risk is that a malicious or compromised owner can rename a token to impersonate another one, or quietly change links after a rug.
Why it matters before you trade
Mutable metadata is a low-severity flag on its own. It matters more in combination: a new token with mutable metadata, a live mint authority and a name close to a popular ticker deserves extra caution. Always confirm the contract address rather than trusting the name.
How NAVI shows it
When a token's RugCheck report raises "Mutable metadata", NAVI lists it among the named risks on the token page's rug check, with a plain explanation of what the update authority can change.

- Mint authorityThe account allowed to create new units of a token. If it is still set, someone can increase the supply at any time; if it is revoked, the supply is fixed.
- Copycat tokenA token that reuses the name, ticker or logo of a better-known token so buyers mistake it for the real one.
- Contract address (CA)The unique on-chain address of a token. On Solana it is the token's mint address, and it is the only reliable way to identify a token.
