Token authorities are special permissions that control how a Solana token behaves. There are three main authorities: Mint Authority (can create new tokens), Freeze Authority (can freeze tokens in wallets), and Update Authority (can change token metadata like name and logo).

Checking authorities helps you understand the risks. If mint authority isn't revoked, the creator can print unlimited tokens and dilute your holdings. Active freeze authority means your tokens could be frozen at any time. These are common red flags for scam tokens.

When an authority is revoked, it means that permission has been permanently removed and cannot be restored. This is generally good - it means the token creator gave up control. For example, revoked mint authority proves the supply is fixed and cannot be increased.

No! Some legitimate tokens keep authorities for valid reasons. For example, USDC keeps mint/freeze authorities for regulatory compliance and redemptions. We mark trusted tokens (like USDC, USDT, wSOL) with a blue verified badge to explain why they retain certain authorities.

Risk scores range from 0-100. Lower is better: 0-30 is Low Risk (most authorities revoked), 30-60 is Medium Risk (some authorities active), and 60-100 is High Risk (multiple authorities active). However, always read the details - some high scores are legitimate (like stablecoins).

Yes! You can paste token URLs from Solscan (solscan.io), Solana Explorer (explorer.solana.com), or Birdeye (birdeye.so). Our tool automatically extracts the token address from these URLs.

sØl is a RugCheck alternative that checks the same core authorities (mint, freeze, update) with a clear risk score. Both tools verify on-chain data directly. sØl also integrates with our other tools — after checking a token, you can track it in our portfolio tracker or use our token manager to revoke authorities on your own tokens.
