DeVault's system is built in a way that whenever you generate a value, there's always some extra value generated alongside. That extra value then aims to be distributed among DAOs already working on the project and you, DeVault user.
Here you can browse proposals created by other users and vote with your collected coins on projects that you believe are worth it. Don't worry, none of your coins will be spent on the voting process. All that matters is that you own, and hold the coins until the proposal you voted on ends.
