# What is Blacksail Finance?

**Blacksail Finance** is an advanced smart contract yield compounding suite built on the Sonic Blockchain network. Blacksail helps users earn more cryptocurrency by automatically compounding their DeFi rewards for their crypto tokens into their original assets, allowing users to easily earn more of their favorite holdings. 

Additionally, while other projects retain their revenues and charge substantial fees, Blacksail instead reinvests and distributes rewards through a bonded USDC revenue token known as **SAIL**. This approach allows users to grow alongside the platform and build their own treasury reserve backed by a liquid stable coin.  SAIL tokens can be redeemed from the bonding curve to receive USDC, while the value of the tokens is scaled up as demand increases. SAIL can also be used as collateral to borrow USDC for other uses while earning swap revenues.

Blacksail Finance is on a mission to fortify decentralized finance on the Sonic Network. The Blacksail protocol aims to support all of the projects on the Sonic Network by:&#x20;

* Developing customized yield strategies that both optimize and align incentives on each platform, driving robust liquidity to the ecosystem.
* Removing the guesswork and difficulty of discovering and capitalizing on yield strategies for our users. Allowing them to receive more of their favorite tokens without any additional work.
* Empowering individuals to build a liquid USDC reserve (represented by the SAIL token) to strategically fund and invest in both up and coming and established Sonic protocols alike.
