# Overview  
  
[Compound](https://iq.wiki/wiki/compound) Protocol is an [Ethereum](https://iq.wiki/wiki/ethereum)-based lending and borrowing protocol. The protocol provides cTokens, representing the funds a user has deposited in the [Compound](https://iq.wiki/wiki/compound). cWBTC is a category of cTokens that users can receive in exchange for depositing WBTC.  
  
Each asset integrated with the Compound Protocol is connected through a cToken contract, adhering to the EIP-20 standard for representing supplied balances. [Minting](https://iq.wiki/wiki/minting) cTokens provides users with the opportunity to earn interest through the cToken's exchange rate, which increases relative to the underlying asset, and enables the use of cTokens as collateral.
