How can i change the Transaction version?

[jiuyaopinyin]

I had add the bitcoinTestNet and rebuild
when i use the demo to signand push "https://api.blockcypher.com/v1/btc/test3/txs/push"
error = "Error validating transaction: Transaction 64733fe9a3a8be05b848679612e58266ac969bc1761a782f343537c55054b6a0 orphaned, missing reference df652f1f56e9fd94c19f87b86a2a3df654ddc74a68ff376a45e9786a9e991485."

how can i sign the Transaction with version 2

let coin: CoinType = .bitcoinTestNet
        let privateData = Data(hexString: privateHexStr)!
        let secretPrivateKeyBtc = PrivateKey(data: privateData)!
        let addressBtc = bitCoinPrivateKeyToAddress(privateKey: secretPrivateKeyBtc, prefix: CoinType.bitcoinTestNet.p2pkhPrefix, isSegwit: false)
        print(addressBtc)
        // Build a transaction
        let toAddress = "n3Jhg7HKYcYSZCScoTAeFCvJ4ywG6Srh2G"
        let changeAddress = "miEs7HKq37uBxyVMCbHiLuEfbogaN3GmWx"
        let outPoint = BitcoinOutPoint.with {
            $0.hash = Data(hexString: "8514999e6a78e9456a37ff684ac7dd54f63d2a6ab8879fc194fde9561f2f65df")!
            $0.index = 0
        }
        let utxo = BitcoinUnspentTransaction.with {
            $0.amount = 133352
            $0.outPoint = outPoint
            $0.script = BitcoinScript.lockScriptForAddress(address: addressBtc, coin: coin).data
        }
        var input = BitcoinSigningInput.with {
            $0.amount = 600
            $0.hashType = TWBitcoinSigHashTypeAll.rawValue
            $0.toAddress = toAddress
            $0.changeAddress = changeAddress
            $0.byteFee = 2
            $0.coinType = coin.rawValue
        }
        input.utxo.append(utxo)
        input.privateKey.append(secretPrivateKeyBtc.data)

        // Calculate fee (plan a tranaction)
        let plan: BitcoinTransactionPlan = AnySigner.plan(input: input, coin: coin)
        print("Planned fee:  ", plan.fee, "amount:", plan.amount, "avail_amount:", plan.availableAmount, "change:", plan.change)

        // Set the precomputed plan
        input.plan = plan
        input.amount = plan.amount

        let outputBtc: BitcoinSigningOutput = AnySigner.sign(input: input, coin: coin)

        print("Signed transaction:")
        print(" data:   ", outputBtc.encoded.hexString)
```

Wallet core does not support Testnet.
From the error message I guess that this transaction was interpreted as a mainnet transaction and the mentioned hash (df..85) was not found there.
Can you elaborate what do you mean by version 2?

[jiuyaopinyin]

sorry ,i mean the version by TW_Bitcoin_Proto_Transaction in TW_Bitcoin_Proto_SigningOutput

[jiuyaopinyin]

Is it possible that after I modify some parameters myself, I can let Wallet core support Testnet?

Hi ,

How can I get hash value ?

let outPoint = BitcoinOutPoint.with {
$0.hash = Data(hexString: "8514999e6a78e9456a37ff684ac7dd54f63d2a6ab8879fc194fde9561f2f65df")!
$0.index = 0
}
