# Credit Staking and XBTC Staking

BTC holders can become BTC Validators on the exSat network by staking their #BTC through either [**Credit Staking**](https://docs.exsat.network/guides-of-data-consensus/others/operation-references/validator-operations/stake-for-validator-via-credit-staking) or [**XBTC Staking**](https://docs.exsat.network/guides-of-data-consensus/others/operation-references/validator-operations/stake-for-validator-via-xbtc-staking-or-xsat-staking). Each method has distinct features and benefits, as outlined below.

***

### **Credit Staking**

Credit Staking allows BTC holders to retain self-custody of their #BTC on the Bitcoin network. By proving control over a specific BTC address and maintaining a locked balance of at least **100 #BTC**, users can qualify as BTC Validators. This method plays a key role in promoting decentralization and enhancing the security of the exSat network. However, it comes with certain limitations:

* **Fixed Staking Amount:**\
  Only two states are recognized: 0 #BTC or 100 #BTC.
  * If the BTC address balance falls below 100 #BTC, Credit Staking is deactivated and considered 0 #BTC.
  * If the balance is 100 #BTC or more, the staking amount is fixed at 100 #BTC—regardless of the actual balance (e.g., even with 1,000 #BTC, only 100 #BTC counts toward Credit Staking).
* **No XBTC Minting:**\
  BTC staked via Credit Staking does **not** generate XBTC, meaning it cannot be used in any on-chain yield-generating activities, such as quantitative strategies or restaking on the exSat chain.
* **Lower XSAT Reward Weight:**\
  Credit Staking typically earns a lower XSAT reward per BTC compared to XBTC Staking.
* **Mandatory XSAT Donation:**\
  A **20% portion** of the XSAT rewards earned through Credit Staking must be donated to the XSAT Foundation.

### **XBTC Staking**

In contrast, XBTC Staking involves bridging BTC to the exSat network and minting XBTC, which can then be staked to become a BTC Validator. This approach offers several advantages:

* **Secure Custody with Licensed Providers:**\
  Bridged BTC is safeguarded by regulated custodians such as **Ceffu** ,**Standard Chartered Bank** and **Cactus**. For large holdings, assets are stored in **dedicated cold wallets**, and users can monitor their BTC to ensure full transparency and security.
* **No Staking Limitations:**\
  A minimum of **100 #XBTC** is required to become a BTC Validator, but there is no upper limit. The more #XBTC you stake, the more #XSAT rewards you earn.
* **Participation in On-Chain CeDeFi Yields:**\
  XBTC holders can access the full suite of CeDeFi opportunities on the exSat network—such as **quantitative strategies**, **restaking**, and other high-yield protocols—while simultaneously participating in consensus.
* **Higher XSAT Reward Weight:**\
  The reward weight per unit of XBTC is **higher** than that of BTC staked via Credit Staking, enabling greater XSAT earnings for the same notional amount.
* **No Mandatory Donations:**\
  XSAT rewards earned through XBTC Staking are **fully retained** by the staker—no contributions to the XSAT Foundation are required.
