//Imports
import { AssetBTC, AssetBCH} from '@xchainjs/xchain-util';

Estimate a Single Swap

// Instantiate a new ThorchainQuery class with api's
const thorchainCache = new ThorchainCache()

// Estimate a swap from USDC to RUNE
// Create asset from string
const assetUSDC = assetFromString('ETH.USDC-0XA0B86991C6218B36C1D19D4A2E9EB0CE3606EB48')
const estimateSwapUSDC = async () => {

        destinationAddress: 'xxx',
      }
    const estimate = await thorchainQuery.estimateSwap(swapParams)
    printTx(estimate, swapParams.input)
}
