I created a token 2 days ago and have spent over 20 hours in that time attempting to associate to it a name, symbol and picture. I have searches far and wide and can’t find any functioning advice online. You would think that naming your token would be the simplest part but it has proved to be a nearly impossible task. If there is any documentation on this at all, it is VERY well hidden because I haven’t been able to find a singe up-to-date piece of info yet. I tried using the Vercel Token Creation app to “Update my Metadata” but I get a “Blockhash Not Found” error every time. I’ve asked about this on dofferent subreddits and discords, I’ve googled the issue, and it seems I’m the only person to ever receive this error message. How is it that a problem so simple is so impossible to solve?
Have you tried fluxbeam.xyz? They have some tools for updating token metadata.
