OpenLeverage Protocol

The OpenLeverage Protocol comprises Smart Contracts in Solidity for permissionless lending and borrowing assets for leverage trading with DEX integration.

• Through provided API, anyone can create a pair of lending pools for a specific token pair.
• LToken, similar to CToken of Compound, is an interest-bearing ERC-20 token to be received by the fund supplier when they supply ERC-20 tokens to the lending pools. The LToken contracts track these balances and algorithmically set interest rates with a kinked model for borrowers.
• All margin trades will be executed against the liquidity pool of DEX, like Uniswap.
• Risk is calculated with real-time price from AMM.
• Positions are protected with OnDemand Oracle utilizing TWAP from AMM.
