How to Revoke Mint Authority on SolanaPermanently cap your token supply · One-click · Irreversible
Revoking mint authority is one of the most important trust signals for a Solana token. It permanently prevents anyone from ever creating new tokens — effectively capping the total supply forever. Here's what it means, why it matters, and how to do it.
What Is Mint Authority?
Every Solana SPL token has a "mint authority" — a wallet address that has the power to create (mint) new tokens. When you create a token, your wallet is set as the mint authority by default.
This means that at any time, the mint authority can issue millions or billions of new tokens, diluting existing holders. This is a major red flag for buyers and DEX listings.
Revoking mint authority sets it to null — permanently. No new tokens can ever be minted. The total supply is locked forever.
The Three Revocations Explained
Revoke Mint Authority
Permanently prevents new tokens from being minted. Caps the total supply forever. This is the #1 trust signal for buyers and required by most token auditors.
Revoke Freeze Authority
Prevents any token account from being frozen. Required by most DEXes (including Raydium) before they will list your token. Without this, the token creator could freeze users' wallets.
Make Metadata Immutable
Locks your token name, symbol, logo, and description on-chain permanently. Prevents the creator from changing the token's appearance after launch. Strong signal of legitimate intent.
