I can’t broadcast the transaction to the zcashd testnet.

below is my message,

What version of zcashd are you running? How are you generating the raw transaction? As per the error Overwinter is active on the testnet so you’ll need to make sure you are creating transactions in the version 3 format as per: zips/zip-0202.rst at main · zcash/zips · GitHub

Thanks for your information.
Now I’m using ‘zcash-bitcore-lib’ to create raw transaction. Like below…

var privateKey = new bitcore.PrivateKey(‘L1uyy5qTuGrVXrmrsvHWHgVzW9kKdrp27wBC7Vs6nZDTF2BRUVwy’);
var utxo = {
“txId” : “115e8f72f39fad874cfab0deed11a80f24f967a84079fb56ddf53ea02e308986”,
“outputIndex” : 0,
“address” : “17XBj6iFEsf8kzDMGQk5ghZipxX49VXuaV”,
“script” : “76a91447862fe165e6121af80d5dde1ecb478ed170565b88ac”,
“satoshis” : 50000

var transaction = new bitcore.Transaction()
.to(‘1Gokm82v6DmtwKEB8AiVhm82hyFSsEvBDK’, 15000)

Looks like that library hasn’t been updated in some time so I guess it’s not creating v3 transactions that are compatible with Overwinter. There’s actually already an issue open https://github.com/BitMEX/zcash-bitcore-lib/issues/6.
