Revoke Solana token authority

Frequently asked

How do I revoke the mint authority of my Solana token?

Pick the mint from the 'Controlled mints' picker (or paste its address), tick 'Revoke mint authority', and your wallet signs. The mint authority is set to None in one transaction — anyone reading the mint sees a fixed supply going forward. The change is permanent.

What does revoking mint authority actually do?

It sets the mint's mint_authority field to None. No further supply can ever be minted, by you or anyone. The current supply becomes the maximum supply forever. This is one of the strongest commitments a creator can make to holders — the most reliable on-chain signal that the supply won't be inflated.

What does revoking freeze authority do?

It sets the mint's freeze_authority field to None. No one can ever freeze a holder's token account, so no one can stop a holder from selling. Active freeze authorities are the most common honeypot mechanism on Solana; revoking it removes that risk for every current and future holder.

Can I undo a revoke?

No, never. Revoking is one-way at the protocol level — the Solana program literally checks for None and refuses to accept a set-authority instruction once the authority is None. The only way to get a fresh mint authority is to deploy a new mint. Plan accordingly.

Why are mint and freeze authority flagged as risks by rug checkers?

Mint authority means the creator can keep minting and dilute every holder. Freeze authority means the creator can freeze any wallet from selling. Both are unilateral powers that put buyers at the creator's mercy. Revoking them removes the levers — safety checkers (including SolKnife's own) read the mint and emit a positive signal when both are None.

Can I revoke both authorities in one transaction?

Yes. The tool packs both set-authority instructions into a single tx so you sign once. If you only want to revoke one (e.g. keep freeze authority for a regulated stablecoin), tick only the one you want; the other stays untouched.

What if I want to keep one authority for now?

Just tick the one you want to revoke; leave the other unchecked. Most creators revoke mint authority first (right after minting the final supply) and keep freeze authority off from the start (SolKnife's create-mint defaults to no freeze authority for this reason).

Does this work for Token-2022 mints with extensions?

Yes. Token-2022 mints with any combination of extensions (transfer fee, interest-bearing, confidential transfer, etc.) use the same set-authority instruction shape as classic SPL Token mints. SolKnife reads the program and routes the tx to the right one automatically.

Will my token's display change after revoke?

Yes — token-safety tools and explorers update within seconds of confirmation. A token that was 'mint authority: active' becomes 'mint authority: revoked' on every site that reads on-chain data, and the safety signals from rug-checkers flip accordingly.

Can someone else revoke my authority?

Only if they're the current holder of that authority. The tool checks: only the wallet that actually holds the mint or freeze authority can sign the revoke tx for that authority. If you transferred the authority away, only the new holder can revoke it (or transfer it further).
