What are mint and freeze authority on Solana?
Short answer: mint authority is the right to create new supply; freeze authority is the right to freeze any holder's token account so it can't move. For a memecoin, both should be revoked (set to none). If either is ON, treat it as Risky.
Why it matters
- Mint ON: the holder of that key can mint billions of tokens and sell them into the pool, crashing the price.
- Freeze ON: a honeypot setup. You can buy but your account can be frozen before you sell.
When it is normal
Stablecoins such as USDC keep both for regulatory reasons. That is expected for regulated issuers, not for anonymous memecoins.
