With Waves

You can buy SIGN Utility tokens on the Waves Exchange by trading it using Waves.

A feature allowing you to trade Waves for SIGN directly in the sign-web.app was available in previous versions of the web application but is on hold at the moment since the project switched from Waves Keeper to Waves Signer, the latter one doesn't support "orders" yet.

This feature will be back as soon as Waves Signer supports it again.
