Solrise maintains a list of base assets that users can deposit to buy into a fund. A base asset is the assets that users can deposit to a fund. Solrise currently supports USDC (on Solana), with plans to add more base assets via protocol upgrades. Funds can use one or more base assets, which are initially determined by the fund manager when a fund is created. Funds can allow or block deposits in more base assets via governance action. This change does not affect the existing balances in the fund - if one base asset is removed, the balance in the fund remains, but users cannot make deposits in that asset anymore.
