Great package!

Could we put on the roadmap, the ability to initiate the RPC requests in order to support DApp integrations more easily?

From what I understand, this package provides the receiver/wallet side of the protocol, but I am looking to use Flutter to ask a wallet connect capable wallet to personal_sign, eth_signTypedData etc. (e.g. https://docs.walletconnect.com/1.0/json-rpc-api-methods/ethereum#eth_signtypeddata https://docs.walletconnect.com/1.0/quick-start/dapps/client#sign-typed-data-eth_signtypeddata)

The package already initiates rpc requests with updateSession() in lib/wc_client.dart, so adding "sendRequestXXX" should be straightforward. I think... ;-)

Even supporting a single 'Send Custom Request' method would help, as we could author our own support with effort.

I tried to connect MetaMask wallet in debug mode and is working fine. But when we create release build it stops working. It still able to open MetaMask, but after unlock the MetaMask account it won't prompt the dialog for connect wallet.

Wallet Connect v1 is will end of support. ( 2022. 12. 16 )
Do you have any plan support Wallet Connect v2?

I'm working on a wallet app with wallet connect.
When I got a request by onEthSendTransaction, I just did these things below:

1. Get the info from wallet connect.
2. Sign the transaction.
3. Send transaction by web3 and get the txHash.
4. wc.approveRequest(id: id, result: txHash). And the id is get from 1.

I can check the transaction on explorer. But the dapp web is still waiting for me to confirm the transaction.

Is there anyone can help me?
Thanks!

Please does this package support integration with Binance smart chain?

Hello guys, I got this error when doing transaction from dApps for algorand

Description

When connecting multiple sessions through WC and caching the connected sessions list, it's important for us to know whether the WCClient is already connected or not, so we can restore the session or initiate a connection.

i have a smart contract with multiple functions that allow user to pay bills in crypto currencies .i just want to known how can i call smart contract functions through web3dart without private key.I already connect wallet with walletconnect but how can i use them instead of private key.Is there any option in walletconnect to call smart contract function?.

Im having handshake exception dont know if i'm doing anything wrong, please check below

from pancakeswap.finance: "You are connected to the wrong network

Hey guys,
I was trying out this lib's example code to see how it works, and when I load it as a web app it just shows this:

And there's no way to connect it to metamask (my wallet). Is this library fully ready. I'm just testing it on web, but my needs are I need a way to use walletconnect on a mobile device.

I tried with sample app in android but it is not working.
Not connect or not showing up other things like application selection.
Is there any way to use it in android app.

After connecting to opensea with walletconnect, I connect to uniswap. When I want to operate on opensea again, I get a HandshakeException error, how can I follow. I only get a request from the last dapp I connected to.

Hello. I see only eth example, but how can I check and handle erc20 token transaction? Cause if this is a token transfer that it should be other handling in web3. Can you show an example with tokens?

inappwebview does not show connect to mobile wallet on ios ,

but a list of some wallet app .

how can i use it on ios?

thanks!

Future<void> updateSession({ List<String>? accounts, int? chainId, bool approved = true, }) async { final param = WCSessionUpdate( approved: approved, chainId: _chainId ?? chainId, accounts: accounts, ); final request = JsonRpcRequest( id: DateTime.now().millisecondsSinceEpoch, method: WCMethod.SESSION_UPDATE, params: [param.toJson()], ); return _encryptAndSend(jsonEncode(request.toJson())); }

In this block chainId is never updated. It always uses current _chainId .

to Update Session we need to call approveSession method first then call updateSession method

i am trying to connect trust wallet to wallet connect session using deeplinks but i did not get any wallet connect popup. but i am getting popup on metamask app

The wallet can be connected to more than one dapps. How do we know which dapp triggered the function?? For example, if we take onEthSign...

When I use wcClient.disconnect() to disconnect, but Dapp shows that I am still connected.

How can it be make for the desktop so that it is the one who is connected to it from the mobile and not the one who requests the connection ?

I had connecting to two Dapps, now i want to disconnect from only one Dapp.
I try to use killsession, and two Dapps' sessions were been killed.
Please teach me how to do, thank you.

I've been trying the example and connecting to Metamask app on my phone, I am unsure if this is web-only, or does it support android too, because it doesn't show a list of apps when I open it on my android phone, do I need to make some additional configurations ? I was unsure as there is not any documentation around it, within the codebase too. It'd be great if I can get some help figuring this out.

hello, first of all, thank you very much for the package you developed. The wallet connect plugin on pub.dev is out of date. The updateSession function is not working because it was last updated 11 months ago and there are no chainID changes.

step1:
open the opensea.io, and connect walletconnect

step2:
open profile -> collected, and open the own collect.

step3:
click the sell button, to sell my collect.

step4:
set the price, click "Complete listing" button, then click "unlock" button

step5:
click "sign" button in walletconnect.

then error:
There was an error with your transaction. Please try again.

By clicking "Connect to WalletConnect", a popup shows up, when I select Metamask from the wallet list, nothing happens. Below error shows up. Does it suppose to open the installed Metamask App?

Sometimes the program will be exited without reason
the close code is 1005
For the definition of code, refer to the definition document of Web Socket
https://www.rfc-editor.org/rfc/rfc6455#section-7.4

(Actually it's always 1005 when the dapp call loginout, the sdk will not notify program,and direct call disconnect then throw a code of 1005,for example, on opensea.io),see the following code.


It is noteworthy that
_ webSocket._ webSocket._ closeCode
_ webSocket._ webSocket._ closeReason
There are values in.But obviously these are internal properties I can't access. In addition, I added the Reason and Close parameters on my own initiative.

So in the onDisconnect event, I can't determine whether it is an unexpected end or the user's active end
(If it is an accidental termination, I can reconnect and continue to communicate with DAPP, but if it is the user's active termination, there is no connection significance.)

The difference between the two is that when DAPP is disconnected, according to the official document of WalletConnect, a SessionUpdate method must be sent.
So I added this onSessionUpdate event and called it so that the program can determine whether to reconnect or disconnect

Good afternoon, please how can I preserve my session while restarting app flutter in flutter?

Environment

I'm trying to develop a mobile app in Flutter which should interact with a very simple contract.
The contract contains a basic string which can be read or write.

My environment is the following:

• Ganache running on localhost, with the contract deployed at a know address.
• A physical Android device with adb-reverse to reach the Ganache network.
• On the Android I've Metamask app installed with the Ganache network set and one of the Ganache account.

I'm using the following dependencies:

  web3dart: ^2.3.0
  walletconnect_dart: ^0.0.11
  url_launcher: ^6.1.5

I use the Web3Dart code generator to generate the class to interact with my contract.

Expected behaviour

The app has a login button, which redirect the user to Metamask for the login, and it initialise the session.
After that it displays a screen with a text containing the value of the contract variable, a textField and a button.
Tapping on the button should execute a transaction that updates the value on the contract with the textField content.

Problem

After looking around on Github for examples I was able to assemble the code and make it work.
The EthClient, the Connector and the Contract are initialised correctly.
At login button tap the user is switched to Metamask and a popup ask to connect to the mobile app.
After that the user can interact with the TextField and submit the new value.

I copied the WalletConnectEthereumCredentials from the example folder and here's my version:

class WalletConnectEthereumCredentials extends CustomTransactionSender {
  WalletConnectEthereumCredentials(
      {required this.provider});

  final EthereumWalletConnectProvider provider;

  @override
  Future<EthereumAddress> extractAddress() => Future(
      () => EthereumAddress.fromHex(provider.connector.session.accounts.first));

  @override
  Future<String> sendTransaction(Transaction transaction) async {
    final from = await this.extractAddress();
    final hash = await provider.sendTransaction(
      from: from.hex,
      to: transaction.to?.hex,
      data: transaction.data,
      gas: transaction.maxGas,
      gasPrice: transaction.gasPrice?.getInWei,
      value: transaction.value?.getInWei,
      nonce: transaction.nonce,
    );

    return hash;
  }

  @override
  Future<MsgSignature> signToSignature(Uint8List payload,
      {int? chainId, bool isEIP1559 = false}) {
    // TODO: implement signToSignature
    throw UnimplementedError();
  }
}

When the user tap on the button, a transaction is sent.
Now if the user want to proceed he has to open manually Metamask and confirm the transaction through a popoup.

Is there a way to avoid having to move in Metamask and confirm every simple transaction every time, then switch back in the app?

I was able to automatically open Metamask every time a transaction is sent, with this code inside the sendTransaction:

 launchUrlString(metamaskUri, mode: LaunchMode.externalApplication);

But still a confirmation for every transaction is needed.

Thanks

How can i retrive a privete key of a wallet?

I can't sign message to use NFT platforms as Opensea or Rarible with Ethereum network.

I wanted to use this plugin to try and sign in to my Metamask wallet on iOS or Android completely natively, but your example uses an InAppWebView that completely hides what happens when we click the "Connect to WalletConnect" button. As a Wallet Connect newbie I'm completely lost. Is it a requirement to go through a web page that does most of the work like that, and if so, can you share how you implemented the website on example.openwallet.org? And if it's possible to do everything natively, could you show an example of how to do that, with clearer indication as to what the values for each parameter should be? Right now the documentation is not very helpful.

As per the docs, after creating instance of WCClient, we need to create a session:

final wcUri = '...';
final session = WCSession.from(wcUri);

I am new to blockchain and crypto wallets.
Can some one please help me understand, how can I create the wcUri?
Also, does the WCClient automatically stores the session and we don't need to re-authenticate on every app launch?

Thanks.
