# FAQs #### Why build on Solana if it is a multi-chain protocol? Solana offers the highest throughput and lowest latency of any major blockchain. To rebalance ETF portfolios efficiently without losing money to gas fees, we need a high-speed execution layer. Solana is the engine; other chains are the fuel sources. #### Is my money safe when I bridge it? Security is our top priority. The Nexus Layer uses a decentralized network of validators rather than a single centralized server. Furthermore, the I-PoSR consensus ensures that the network is secured by the diverse value of all assets it holds, making it economically expensive to attack. #### Do I need to run a node to use Spectra? No. Regular users can simply connect their wallet, deposit assets, and buy ETF shares. Running a Nexus Node is an advanced feature for technical users who want to earn extra yield by helping verify transactions. #### Where does the yield come from? Yield comes from two places: the natural appreciation of the assets in your portfolio, and the automated strategies Spectra uses, such as lending idle assets to safe protocols like Solend or Kamino to earn interest. #### How often does the portfolio rebalance? The AI engine monitors the market 24/7. Rebalancing occurs whenever the market drift exceeds a certain threshold defined by the ETF parameters. Thanks to Solana speed, this can happen multiple times a day if necessary. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
