No. The first time you post, reply or react, your wallet asks for one signature. It covers posts, replies, reposts, rockets, deleting your own posts, comments, War Room chat, reports, hide and block, and creator updates for 30 days.
A signature is a message, not a transaction. It costs no gas, moves no funds and gives nobody access to your money. The message starts with MemeWarzone API Action. If a prompt asks you to approve a transaction or spend tokens when you only wanted to post, reject it.
The signature is kept in this browser. On another browser or device, or with another wallet, you sign once more. Payments, claims, votes and challenges ask each time.
