You can unstake your tokens instantly at any point in time. \ **How do I add new TAO to Mentat?**\ If you already have an address using Mentat, you can just send more funds to your account and they will get automatically staked in the next 24 hours. **What are Mentat's fees?**\ Mentat does not charge any fees on transactions or users’ gains. Revenue is generated through a standard 9% staking fee, all while optimizing for the best possible APY. To put it simply, if a portfolio of 10 TAO earns 1 TAO from staking, Mentat will take 9% of that earned TAO, or 0.09 TAO. **Is there a minimum requirement for using Mentat?**\ Yes. For Build your allocation, the minimum depends on what you select: 0.5 TAO per index and 0.1 TAO per subnet. For example, if you only choose one bundle, you need at least 0.613 TAO; if you only choose one subnet, you need at least 0.213 TAO in your wallet. For One-Click Strategies you should have at least 0.5 TAO in your wallet. **Why do I have 0.093 “Reserved” TAO?**\ This is a portion of your TAOs that is necessary for the [proxy](/mentat/security/what-makes-mentat-secure.md) to function. These TAOs are not working but will be returned to you if you decide to revoke it. **Why do I have 0.3 “free” TAO?**\ These are TAO that are not staked. They are used to cover all transaction fees. **What is the “Remark” when I sign into my wallet?**\ It's an encrypted message added by Mentat in the remark field of a transaction, allowing the platform to internally track details like partner, allocation, or the wallet's DCA strategy, while keeping this information confidential and inaccessible to external users. \ **I need more help. Where should I ask my questions?**\ If you have any questions or would like to discuss Bittensor or subnet tokens, feel free to join our Discord server:
