What Is Mint Authority?
Mint authority controls who can create new tokens and increase supply. Learn why revoking mint authority is essential for token trust.
Mint authority on Solana is the permission to create (mint) new tokens and increase the total supply. The wallet holding mint authority can generate unlimited additional tokens at any time.
Why Mint Authority Matters
If mint authority is active, the holder can inflate the supply at any time — diluting all existing holders. This is why revoking mint authority is one of the most important trust signals for any token project.
Revoking Mint Authority
When you revoke mint authority, the total supply is permanently fixed. No one — not even the original creator — can ever mint more tokens. This is irreversible by design.
Analytics tools like RugCheck and DexScreener flag tokens with active mint authority as a risk factor. Experienced traders check mint authority status before buying.
