ChatPatcher

yep, it's paint.

ChatPatcher is a Velocity plugin that removes the signed chat messages feature introduced in Minecraft 1.19+
If you’ve encountered errors such as:

• “A plugin tried to cancel a signed chat message”
• “A proxy plugin caused an illegal protocol state”

you're likely to require this one!

for reference

Why Use ChatPatcher?

With the release of Minecraft 1.19.1, Mojang introduced mandatory signed chat messages to enhance security and message integrity. While this change aims to reduce abuse and ensure authenticity, it has inadvertently caused compatibility issues for networks relying on Velocity's chat manipulation features. ChatPatcher removes these restrictions, restoring the classic chat handling that many servers have long depended on.

Usage

ChatPatcher requires no setup and no dependencies.

Beware! ChatPatcher DOES NOT replace Paper side plugins such as NoPopup, NoChatReports, ...

Actually, we don't do any packet modification, we're just tweaking Velocity using reflections (ik, i also hate that, but better than having to maintain a fork).
