Shutter Shielded Voting has been great for Snapshot, it keeps votes private until voting ends, which stops people from copying others or gaming the system. We're excited about the API migration making this privacy feature even better for the thousands of DAOs using Snapshot.

Kleros
Shutter's API has been a game-changer for us, by hiding juror votes until voting completes it strengthens the crypto-economic security at the heart of Kleros. Integration was a breeze and the service has been rock-solid since launch.

Decent DAO
At Decent, we have been fighting for the transparency brought by blockchains for many years, to make the world a safer and fairer place. Unfortunately, just yeeting all of an organization's data onchain produces a host of new problems. We need nuanced solutions to make the data that should be private, truly private, without sacrificing the security of blockchains. Thats where Shutter comes in.
