Key facts

  • Irreversible on-chain action
  • Improves Launch Score trust signals
  • Atomic fee — pay only on success

What this tool does

Sets the mint authority to null on-chain so no wallet can create additional supply. This is irreversible and is one of the strongest launch hygiene signals for buyers.

Who should use it

Token founders who have finalized supply and want to prove no more tokens can be minted.

When to use it

After minting and any planned airdrops or treasury allocations — before public launch marketing.

Step-by-step usage

  1. Connect the wallet that currently holds mint authority.
  2. Open Token Control and select your token mint.
  3. Review mint authority status and Launch Score impact.
  4. Click Revoke Mint Authority and approve the transaction.
  5. Refresh your public Launch Score and share the updated trust page.

Fees

0.1 SOL MMAC platform fee + Solana network gas. Fee is atomic — charged only if the revoke transaction succeeds.

What happens on-chain

One transaction revokes mint authority and transfers the platform fee to the treasury wallet.

Common mistakes

  • Irreversible — you cannot mint more supply after revocation.
  • Wrong wallet — only the current mint authority holder can sign.
  • Does not revoke freeze authority — that is a separate action.

How it affects Launch Score

Revoking mint authority typically improves Launch Score and removes the "mint authority active" risk flag.
