Step 1: To get the value in USD for a LP token, our exchange abi has method called getLtPrice (contract address'):
{constant: true,inputs: [{internalType: "uint256",name: "_assetPrice",type: "uint256"},{internalType: "uint256",name: "_stablePrice",type: "uint256"}],name: "getLtPrice",outputs: [{internalType: "uint256",name: "",type: "uint256"}],payable: false,stateMutability: "view",type: "function"},
Step 2: Call the getLtPrice method with the current price of ETH and USDC
