Mint authority
Mint authority is the address allowed to create new units of a token, increasing its supply. If a memecoin's mint authority is still active, whoever controls it can mint more tokens at any time and dilute every holder. If it has been revoked, the supply can no longer grow.
Where mint authority lives
On Solana, every token is defined by a mint account owned by a token program. Solana's documentation says the mint account stores the total supply, the decimals, the mint authority and the freeze authority. The mint authority is set when the mint is created and does not have to be the wallet that created or paid for it.
Revoking it
Solana's Set Authority documentation says the current authority can hand a role to another address or set it to None. Setting it to None permanently removes that role. When a token page says mint authority is revoked or disabled, this is what it means: nobody, including the creator, can mint more of that token.
Tokens created with the newer Token Extensions program can carry additional authority types for specific extensions. A revoked mint authority does not tell you about those, so check the whole authority list on an explorer or a scanner.
Why it matters before you buy
Jupiter's risk documentation describes an enabled mint authority as a developer control that lets the creator create additional tokens at any time, potentially diluting existing holders. Its Jupiter Shield warnings flag tokens that have a mint authority. GMGN's token checks show the same thing under a MintDisable field.
Fresh supply can be sold into the pool, pushing the price down and draining the SOL or USDC that other holders would sell into. A revoked mint authority closes that one route. It does not stop holders who already own a large share from selling, and it says nothing about liquidity or about whether the token can be frozen.
How to check
Open the mint address in a Solana explorer and look for the mint authority field, or use the authority indicators that Jupiter, GMGN, RugCheck and similar tools show on token pages. Always confirm you are looking at the right mint address, because Jupiter notes that anyone can create a token with any name or ticker.
Where this shows up
- RugCheck — Solana memecoin traders who want a free, quick risk check (authorities, LP locks, insiders, holder concentration) before buying a token.
- Jupiter — Solana traders who want aggregated routing across DEXes with low or zero fees on major and stable pairs.
- GMGN — Multichain memecoin traders who want smart-money tracking and copy trading across a web terminal and Telegram bots.
- Birdeye — Solana-first traders who want a token tracker with a mobile app, and developers who need a metered on-chain data API.
- DEX Screener — Traders who want a free, multi-chain view of new and trending DEX pairs before they trade on a separate DEX, wallet or bot.
- Phantom — Solana-first users who want one self-custodial app for swaps, cross-chain swaps, Hyperliquid perps and predictions.
