What Is Mint Authority?
Definition
The mint authority is the wallet address authorized to create new tokens for an SPL token on Solana. Revoking it permanently locks the token supply.
On Solana, every SPL token has an optional mint authority — a public key that is allowed to mint (create) new tokens. When you first create a token, your wallet is typically set as the mint authority.
Revoking the mint authority is a one-way, irreversible action. Once revoked, no one — including the original creator — can ever mint new tokens. The total supply becomes permanently fixed.
- Trust: Holders know the supply can never be inflated
- DEX listings: Many DEX aggregators flag tokens with active mint authority as potentially risky
- Decentralization: It signals the creator has given up control over supply
CoinDevTools makes revoking mint authority a one-click operation. Connect your wallet, select your token, and confirm the transaction.
