What it does
Removes the remaining mint, freeze, and metadata authorities on an SPL token in one transaction so the token becomes fully immutable on-chain.
Use this tool to make token immutable in one compact transaction flow. Check authority status, connect the right wallet, and complete the final lock token authority step safely. Once submitted, control over mint, freeze, and metadata updates cannot be restored.
Removes the remaining mint, freeze, and metadata authorities on an SPL token in one transaction so the token becomes fully immutable on-chain.
Reads the mint, freeze, and metadata authority states for the pasted token, lets you review what is still active, then submits one transaction that revokes everything in scope.
Finalize authority management cleanly in one click instead of revoking each permission separately. One warning, one status view, one final lock.
Enter the token's mint address (CA). The tool reads on-chain state and shows whether mint, freeze, and metadata authorities are still active, already revoked, or missing.
Connect the authority wallet from the top bar or use a local signer with a private key. Review the status panel to confirm which controls are still available.
Read the permanent-control warning, then confirm. A single transaction removes all remaining authority access. Supply, freeze, and metadata are then permanently locked.
When an SPL token is made immutable, all remaining authority controls are permanently removed. No one — not even the original deployer — can mint new supply, freeze holder accounts, or change the token's name, symbol, or logo. For most projects this is the final trust signal before listing on a DEX.
Connect the right wallet, confirm the authority states, and click Make Immutable to remove all remaining control in one transaction.
