例如在Uniswap V3
这个DEX的方法调用时,需要传入兑换路径之类的参数,就需要使用encodePacked
操作:
function main() {
var fee = exchange.IO("encodePacked", "uint24", 3000)
var tokenInAddress = "0x111111111117dC0aa78b770fA6A738034120C302"
var tokenOutAddress = "0x6b175474e89094c44da98b954eedeac495271d0f"
var path = tokenInAddress.slice(2).toLowerCase()
path += fee + tokenOutAddress.slice(2).toLowerCase()
Log("path:", path)
}
支持encode
支持decode
