Vaulta

Vaulta is a smart savings platform that automates the protection of users’ stablecoins in DeFi. Many users risk losing funds when a stablecoin depegs or market conditions shift rapidly. Vaulta continuously monitors price feeds via Chainlink, and automatically reallocates funds through a mock Aave pool to maintain stable returns.
Users can deposit, withdraw, and interact with an AI assistant that explains their portfolio, all while the system executes a CRE workflow that integrates blockchain data with external price feeds in real time.
Problem solved: Protects everyday DeFi users from silent losses due to volatility, without requiring manual intervention.
