Token mint
Change a Solana token authority
Transfer a token's mint and/or freeze authority to a new address. The wallet that currently holds the authority signs. This hands control to the new address; to remove an authority entirely instead, use Revoke authority.

How it works
Pick a mint from the 'Your mints' picker or paste a mint address. SolKnife shows which authorities your wallet holds. Tick the ones to transfer, enter the new authority address, and review. SolKnife builds a single SetAuthority transaction reassigning each selected authority to that address; your wallet signs. The change is immediate and hands control to the new address — only it can use the authority afterward. A small flat fee is shown before you sign.
- Mint authority
- The address allowed to mint new supply. Transferring it lets the new address mint; you keep your tokens but lose the power to mint.
- Freeze authority
- The address that can freeze any holder's account. Transferring it hands that power to the new address.
- Transfer vs revoke
- Transferring (here) reassigns the authority to another address. Revoking (the Revoke authority tool) sets it to None permanently. Both are one-way in the sense that only the new holder can change it again.
Frequently asked
- How do I change the mint authority of a Solana token?
- Load the mint, tick 'Transfer mint authority', enter the new authority address, and sign. SolKnife builds a SetAuthority transaction reassigning the mint authority to that address. Only the new address can mint or further change the authority afterward.
- What's the difference between changing and revoking an authority?
- Changing transfers the authority to a new address (it stays active, under new control). Revoking sets it to None permanently so no one can ever use it. Use Revoke authority for the latter.
- Can I get the authority back after transferring it?
- Only if the new holder transfers it back to you. Once you reassign it, your wallet no longer controls it. Double-check the address before signing.
- Does this work for Token-2022 mints?
- Yes. SetAuthority works the same on SPL Token and Token-2022 mints; SolKnife reads the mint's program and routes the transaction to the right one.
- Can someone else change my token's authority?
- Only the current holder of that authority can sign the change. SolKnife checks your wallet actually holds the authority before building the transaction.
