dforce-network / xswap

most easy way to swap between USDx and stable coins.

xSwap

To check on the maximum amount available for swap in one transaction:

• 1). Call contract function getLiquidity(tokenAddress): Get the real-time balance of a particular asset

• 2). Call contract function getAmountByOutput(inputAsset, outputAsset, outputAmount): Get the real-time balance of the inputAsset by providing outputAmount of the outputAsset

eg: To check on the maximum amount available of each asset for swap in respond to the trading request of “USDC-USDT”. First, get the real-time balance of USDT by calling the function getLiquidity(USDT_Address), for instance, let’s assume there are 10000 USDT sitting in the balance. Secondly, call the function getAmountByOutput(USDC_Address, USDT_Address, 10000) to get the real-time balance of USDC which is available for instant swap.
