  const receiver = '<receiver>';
  const exactIn = trade.tradeType === TradeType.EXACT_INPUT;
  const maxSent = exactIn ? trade.inputAmount : trade.maximumAmountIn(slippage);
  const minReceived = exactIn ? trade.minimumAmountOut(slippage) : trade.outputAmount;
  const tradeType = exactIn ? 'swapexactin' : 'swapexactout';

    const input = inputAmount.toAsset();
