Habbo Avatar Perks is a Chrome extension that offers users exclusive avatar perks and benefits on Habbo Hotel websites without the need to own expensive NFT collectibles. By clicking the "Verify Wallet" button, the extension triggers a verification process that involves sending the developer's wallet address to a backend server for authentication.

The backend server then generates a unique nonce associated with the developer's wallet address, signs it with a private key, and sends the cryptographic signature back to the extension. Utilizing this signature, the extension communicates with Habbo servers, tricking them into believing the user owns the premium NFT collectibles, granting access to special avatar accessories, exclusive rooms/events, and other benefits reserved for NFT owners.
