Pledge an action you can do to support the causes you believe in. Learn about it, sign a petition, volunteer, protest, or something else.
Once you've claimed an action, you'll be added to groups with other people who have claimed actions toward the same cause. Introduce yourself and you'll be invited to all sorts of group activities.
Badges are minted NFTs that give you benefits. You can display them on your LinkedIn, Linkinbio, Patreon and other bio areas to show people what you really stand for, not what you say you stand for.
