B4J Question [ Web3X ] Have a way to send Ether between wallets on mainNet ?

Waldemar Lima · Apr 18, 2022

Hello everyone !
Is there any example of how to send ether between 2 accounts on the backend using MainNet?

Erel · Apr 18, 2022

Yes. See posts #4 - #5: https://www.b4x.com/android/forum/threads/web3x-develop-web3-solutions-with-b4x.137350/

It will be easier to help you if you tell us what happens when you run the code.

Waldemar Lima · Apr 19, 2022

when i run in Release, show it on log :

Bash:

*** mainpage: B4XPage_Appear
*** mainpage: B4XPage_Resize [mainpage]
0xdhfyr293jdh8aus929jdasak01923jdajjsldas 'my wallet
*** mainpage: B4XPage_Resize [mainpage]
*** mainpage: B4XPage_Resize [mainpage]
*** mainpage: B4XPage_Resize [mainpage]

after several minutes with the application open, the same log remains as above... looks like it's not calling send funds or something...

Put a breakpoint on line 39 (in the code you posted). Is it reached?

Try it with mainnet (up to the chainid step). You can also upload the project and I'll try it here.

Waldemar Lima · Apr 20, 2022

can i send private with keys or only projet ?

Erel · Apr 21, 2022

Only the project.

Waldemar Lima · Apr 21, 2022

here project !

Erel · Apr 22, 2022

Start with this:

B4X:

Private Sub B4XPage_Created (Root1 As B4XView)
    B4XPages.GetManager.LogEvents = True
    Root = Root1
    Root.LoadLayout("MainPage")
    Utils.Initialize
    Web3Ropsten = Utils.BuildWeb3Infura(InfuraRopstenLink)

    Dim credentials As W3Credentials = Utils.CreateCredentialsFromPrivateKey(Utils.BigIntFromHex(pk).ToByteArray)
    Wait For (Web3Ropsten.EthChainId) Complete (Result As W3AsyncResult)
    Log(Result.Value)
    Wait For (Web3Ropsten.EthGetBalance(credentials.Address, Utils.BLOCK_LATEST)) Complete (Result As W3AsyncResult)
    Log(Result)
End Sub

pk is a global string with the account private key. You can use a wallet instead.

If it doesn't work for you then something is misconfigured. Maybe your infura link or the set of libraries.

Waldemar Lima · Apr 22, 2022

I tested this example code, but even so without a link to the wallet, there is no return... it's as if the http request was not made...

B4X:

Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private Web3Ropsten As Web3X
    Private Utils As W3Utils
    Private InfuraRopstenLink As String = "https://ropsten.infura.io/v3/your_project_id_here"
End Sub

Public Sub Initialize
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    Utils.Initialize
    Web3Ropsten = Utils.BuildWeb3Infura(InfuraRopstenLink)
    Wait For (Web3Ropsten.EthBlockNumber) Complete (Result As W3AsyncResult)
    If Result.Success Then
        Log("Current block: " & Result.Value)
    End If
End Sub

I'm studying the web3x .bas to try to understand what's going on behind .

on line 75 of Web3X.bas when calling the example above, it gets stuck on RunAsync_Complete
as the screenshot above shows.

what is preventing the request?

Erel · Apr 24, 2022

My guess is that your SDK is misconfigured. Carefully follow the instructions: https://www.b4x.com/android/forum/threads/web3x-develop-web3-solutions-with-b4x.137350/#content

Waldemar Lima · Apr 25, 2022

My mistake, I forgot that to update the okhttp library, I would need to update the b4j root directory... ?
Thanks a lot for the help ?

B4J Question [ Web3X ] Have a way to send Ether between wallets on mainNet ?
