}

Construct ioctl Commands

Add liquidity

function addLiquidity() {
  exchange=$1
  min_liquidity=`decimal2hex $2`
  max_tokens=`decimal2hex $3`
  iotx_amount=$4
  dl=`deadline`
  ioctl contract invoke bytecode $exchange 422f1043${min_liquidity}${max_tokens}${dl}
}

Remove liquidity

function removeLiquidity() {
  exchange=$1
  amount=`decimal2hex $2`
  min_iotx=`decimal2hex $3`
  min_tokens=`decimal2hex $4`
  dl=`deadline`
  ioctl contract invoke bytecode $exchange f88bf15a${amount}${min_iotx}${min_tokens}${dl}
}

Get token to IOTX input price

function getTokenToIotxInputPrice() {
  exchange=$1
  amount=`decimal2hex $2`
  ioctl action read $exchange d458a2d1${amount}
}

Get IOTX to token input price

function getIotxToTokenInputPrice() {
  exchange=$1
  amount=`decimal2hex $2`
  ioctl action read $exchange a46f9389${amount}
}

Swap token to IOTX

function tokenToIotxSwapInput() {
  exchange=$1
  token_sold=`decimal2hex $2`
  min_iotx=`decimal2hex $3`
  dl=`deadline`
  ioctl contract invoke bytecode $exchange 10dc202f${token_sold}${min_iotx}${dl}
}

Swap IOTX to token

function iotxToTokenSwapInput() {
  exchange=$1
  iotx_sold=`decimal2hex $2`
  min_token=`decimal2hex $3`
  dl=`deadline`
  ioctl contract invoke bytecode $exchange eecd096a${iotx_sold}${min_token}${dl}
}
