StakeStone StoneBTC and Vault
Summary
The current project revolves around `StoneBTC` and the associated `StoneBTCVault`. The main function of the protocol is to enable users to stake BTC-pegged assets and receive stoneBTC in return. This stoneBTC can be transferred across supported chains using LayerZero's OFT (Omnichain Fungible Token) standard. The use of LayerZero in this context does introduce an unavoidable risk. See the "Operational Considerations" section for detail. The most severe issue found is of medium severity and is related to what may occur in the event of a collateral token depegging from the price of Bitcoin. Moreover, the test suite is significantly underdeveloped and is not in a production-ready status. We recommend all issues be addressed and we strongly suggest the improvement of the test suite. **Update**: The "Unlocked Pragma" suggestion was implemented. All the other issues and suggestions were acknowledged.
