# FAQ **Can anyone mint/burn SSI?** No, only WLPs(Whitelisted Liquidity Providers) are eligible to mint or burn SSI. These providers must complete KYC and KYB verification. For regular users, SSI tokens can be purchased and traded on Uniswap, available 24/7. \ **If I want to make a large SSI purchase, are there other options besides Uniswap?** Please contact our team via email at . \ **How is the underlying asset security ensured？** All underlying assets are held exclusively with regulated & licensed custodians and MPC(Multi-Party Computation) wallet providers. The custodian and MPC wallet provider partners have the highest possible security and are used by all institutional participants in the space. We work with multiple custodians to ensure that the assets held in custody are effectively isolated from both the contract owner and the custodian's own assets, providing the highest level of protection.\ \ **What happens if the underlying assets in the index are adjusted?** If the underlying assets in the index are changed, the corresponding underlying assets within the SSI token will automatically update. This includes any adjustment to the constituent tokens and their weights. These adjustments will be made automatically on a monthly basis, with no action required from users. \ **How are service fees calculated ？** The protocol charges a daily service fee of 0.01% based on the value of the underlying assets. Fees are calculated daily and can be fully traced through the smart contract for transparency. \ **What if I have additional questions or concerns? Who should I contact?** If you have further questions, you can: * Refer to the protocol's official documentation for detailed information. * Contact our support team at for assistance. --- # 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.
