Snapshot
MetFi uses a social voting platform called Snapshot. Snapshot is a decentralized voting platform that is used by many blockchain projects such as Aave, Uniswap, Sushi Swap, PancakeSwap, Curve Finance, Decentraland, and many others.
Snapshot provides a flexible platform for casting votes and calculating voting power in a gasless voting environment, meaning the voter does not pay any gas fees for voting. Snapshot voting is easy, free, safe, and accurate with each vote cast being a signed message that can be easily verified online.
