sendtoaddress feature? about neow3j

[gsmachado]

@pavel-corsaghin thanks for the feature request! Definitely, this would be implemented in the near future.

However, what are you trying to achieve?
If you simply want to send NEO assets from your address to another, and it does not matter where you hold your NEO assets, you can use the raw transaction feature in this project. :-)
If the wallet/address you want to send the assets from is located locked in a NEO node, then, you have two options: 1) either you export the wallet in the WIF format and import it using neow3j; or 2) you can unlock the NEO wallet on the NEO GUI and then use the upcoming sendtoaddress feature as you requested.

Hello @gsmachado, Thank you for reply! I am new in this area so your library very helpful for me. But i have a stupid question, how can i create a raw transaction? I am simply writing an application to send NEO, nep5 tokens and claim GAS from the wallet, I have WIF private key (which created from mnemonic) saved locate in my app and list UTXOs (history transactions) for this address (get from api server). How can I create rawtransaction with your library. Can you create a example for simple transaction instead of "a raw transaction with a 2/3 multisig address". Many thanks and sorry for my english.

i am trying with this:
`
val ecKeyPair = ECKeyPair.create(WIF.getPrivateKeyFromWIF("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"))
val neoAddress = Keys.getAddress(ecKeyPair)
log("address: $neoAddress")

    val rawTx = RawTransaction.createContractTransaction(
        null, null,
        Arrays.asList(
            RawTransactionInput("9feac4774eb0f01ab5d6817c713144b7c020b98f257c30b1105062d434e6f254", 0)
        ),
        Arrays.asList(
            RawTransactionOutput(0, NEOAsset.HASH_ID, "100.0", "AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y")
        )
    )
    val rawTxUnsignedArray = rawTx.toArray()
    val rawInvocationScriptList = Arrays.asList(RawInvocationScript(Sign.signMessage(rawTxUnsignedArray, ecKeyPair)))
    rawTx.addScript(rawInvocationScriptList, Keys.getVerificationScriptFromPublicKey(1, ecKeyPair.publicKey))
    val rawTxSignedArray = rawTx.toArray()
    val rawTransactionHexString = Numeric.toHexStringNoPrefix(rawTxSignedArray)
    log("rawTransactionHexString: $rawTransactionHexString" )

`

But i am not sure about list RawTransactionInput. This is list UTXOs (history transactions of sender address)?. What prevHash and prevIndex means?

[gsmachado]

@pavel-corsaghin so, release version 1.0.8 includes support to sendtoaddress. :-)

[gsmachado]

@pavel-corsaghin just replying to your last message: yes, the RawTransactionInput relates to the unspent amount that you're planning to spend. Then, the prevHash is the hash of the previous unspent transaction (output), and the prevIndex is the index of the previous transaction (also output).

For now, I'm going to close this issue. Let me know if you have some other issues.
By the way, you are welcome to join NEO Discord and ask neow3j questions on the #java channel.
