What is update permission?

It is the power to change how your coin looks in many apps—name, image, description, and links—after launch.

If I lock the profile, can I fix a typo later?

Treat locking as permanent. Fix typos first, check multiple wallets, then lock.

Does locking change supply?

No. Supply rules are a different topic. Locking is about the public profile people see.

Lock your coin’s public profile so the picture and links never change

Understand update permission in plain English, why locking branding can reduce scam worries, and how to remove update permission after your profile is final.

Branding
Trust
Final launch

Picture frame with a check mark meaning final branding

Imagine you launch with a website link in your coin profile. Later, a scammer wishes they could swap that link to a fake site. Update permission is what makes profile changes possible.

Many teams keep things flexible at first, then lock the profile once everything is correct. That is a strong statement: “What you see in wallets is final.”

Benefits of locking your profile

Buyers see a stable identity across apps.
Less fear of sudden link swaps that look like phishing.
A clean story for communities that value “final art” launches.

Update first, lock second

Use Token Metadata Editor until:

The picture looks crisp on mobile and desktop wallets.
The name and short ticker match what you market.
Links go to the real website and social pages you control.

Then use Revoke Update Authority.

How to lock the profile (no code)

Open the revoke tool.
Paste your coin address.
Read the warnings.
Approve in your wallet.
Verify with Solana Token Checker and a real wallet preview.
