 ## Overview
 
 The Automated Portfolio Manager automatically rebalances an investment portfolio using real-time data from onchain and offchain sources. These contracts enable adjustments in asset allocations within a portfolio based on dynamic market conditions, sentiment scores, and volatility indicators such as the Gold Volatility Index (GVZ). This approach provides a modern way to manage digital assets.
