Make Token Immutable
Make token metadata immutable for an existing SPL token with a fixed 0.03 SOL service fee. SolCreate checks update authority first, shows the current mutable state and handles the full no-code wallet flow.
This flow triggers two wallet confirmations: the 0.03 SOL service fee and the final on-chain immutable transaction.
Load the token first, verify the update authority and then make the token immutable when you are ready to lock metadata changes.

How this immutable tool works
Load the token first so SolCreate can fetch the update authority, metadata account and the current mutable property before you sign anything.
Make Token Immutable is a one-way metadata action. Once the mutable flag is turned off, future metadata edits are blocked even if the same wallet still appears as the recorded update authority.
This page is intentionally separate from metadata editing because the user intent is different: first you update fields while the token is still mutable, then you can lock that state with the fixed 0.03 SOL fee when the project is ready.
