It streamlines the process of leveraging positions by automating multiple loops into a single action. With Mach Boost, users can efficiently open and close long or short positions with just one click. #### Key Benefits * **One-Click Leverage:** Simplifies the complex, manual process of looping positions. * **Flash Loan Integration:** Uses flash loans to boost liquidity, enabling efficient margin management. * **Optimized for the SONIC Ecosystem:** Built to integrate seamlessly within Mach Finance, with future interoperability across DeFi protocols in the SONIC ecosystem. *** ### How It Works #### Example Scenario Let’s say you want to open a long position for **wBTC/USDC**. Traditionally, this would require several repetitive steps: 1. Deposit wBTC as collateral. 2. Borrow USDC against your wBTC. 3. Swap the borrowed USDC to wBTC. 4. Repeat the deposit-borrow-swap cycle until reaching the desired leverage. \ Mach Boost automates these steps using flash loans: * **Step 1:** User initiates a flash loan with margin for wBTC to cover the desired leverage * **Step 2:** Deposits the wBTC (margin + flash loan amount) as collateral on Mach Finance. * **Step 3:** Borrows USDC and swaps it for wBTC. * **Step 4:** Repays the flash loan with a small fee, completing the leverage position in a single transaction. To **close the long position**, Mach Boost reverses each step, paying off the borrowed assets and retrieving the original collateral with minimal interaction required from the user.\ For a **short position** on wBTC/USDC, Mach Boost follows a similar process but with USDC as collateral and wBTC as borrowed asset. Here’s how it works: * **Step 1:** Mach Boost initiates a flash loan with USDC margin for USDC to cover the desired leverage. * **Step 2:** The protocol deposits the USDC (margin + flash loan amount) as collateral on Mach Finance. * **Step 3:** Mach Boost borrows wBTC and immediately sells it to acquire USDC. * **Step 4:** The flash loan is repaid with a small fee, finalizing the short position in a single transaction. *** ### Model \ **Architecture** Mach Boost is structured as a Beacon Proxy, which allows for the separation of account liquidity calculations. This design isolates Mach Boost's leveraged positions from a user’s main portfolio on Mach Finance, enhancing modularity and security. **Fees** There are fees associated with this strategy: 1. Flash loan fees depend on the flash loan provider, ranging from 0.09% on Aave to 0.3% on Uniswap 2. DEX Swap fees - Swapping between the Quote & Base tokens depends on the DEX 3. MachBoost fees - 0.1% fees towards the protocol treasury \ **Future Potential** This architecture also supports future interoperability, making it feasible to expand Mach Boost into other DeFi protocols within the SONIC ecosystem, providing a broader range of strategies and liquidity sources.
