Revault is the first and only Defi layer 4 project. They categorize Defi into 3 existing layers - 1. Borrowing and lending, 2. Farming, 3. Vaults. Revault is the 4th layer, a vault aggregator and relayer designed to bring you the best performing vaults for your assets in any given time and rebalance that position whenever a new vault takes the lead, or your active vault is compromised.
It aims to become the Google search of Defi. Revault was born to solve the two major pains in Defi - finding the right place (including risk) to invest your assets, and maintaining that position to always be on optimum.
