# FAQs

**Q: What is liquid staking?**

A: Liquid staking allows you to stake your STRK/BTC tokens while receiving a tradeable token (like xSTRK, xWBTC, etc.) that represents your staked assets, providing both staking rewards and access to liquidity.

#### **Q: How does xSTRK differ from native STRK staking?**

A: xSTRK offers liquidity, faster unstaking in normal conditions and no staking/redemption fees, unlike native STRK staking which locks tokens for 7 days during unstaking.

#### **Q: What is xyBTC?**

A: xyBTC refers to Endur's family of Bitcoin Liquid staking tokens (LSTs), where 'x' is Endur's prefix and 'y' represents different Bitcoin variants. Examples include xWBTC, xtBTC, xLBTC, and xsBTC

#### **Q: How are xyBTCs (e.g. xWBTC, xtBTC, etc.) differ from native BTC staking?**

A: BTC LSTs offers liquidity, faster unstaking in normal conditions and no staking/redemption fees, unlike native BTC staking which locks tokens for 7 days during unstaking.

**Q: How does the value of xSTRK/xyBTC gradually increase over time?**

**A:** xSTRK/xyBTC automatically accumulates staking rewards, increasing its value over time compared to underlying asset (e.g. STRK/BTC). This is called "Automatic Reward Accrual". Staking rewards are reinvested, allowing for compound growth. xSTRK/xyBTC token's value grows to reflect these compounded rewards.

Exchange Rate: As rewards accrue, the exchange rate between xSTRK and STRK increases. For example, 1 xSTRK might equal 1.1 STRK after a period of staking.

Constant Balance with growing value: **While your xSTRK balance remains the same, its value in STRK increases over time.**

#### **Q: Are there any fees for using Endur?**

A: There are no fees on your stake or redemption amount. However, a performance fee of 15% is charged on the *rewards earned*, which is shared between Node operators and LST. 

#### **Q: How long does it take to redeem LST?** 

A: Redeeming LST typically takes anywhere from a few hours to 1–2 days under good circumstances. However, it can take longer. Read more [here](https://docs.endur.fi/docs/concepts/withdraw-log#worst-case-scenario).

#### **Q: Is Endur secure?**

A: Our smart contracts have undergone an audit and you can check out there report in the [security page](https://docs.endur.fi/docs/security). However, as with all DeFi protocols, there are inherent risks users should be aware of.
