Cant get an address of ETC

[danilkharlan]

Hello!

We encountered an issue when attempting to retrieve an Ethereum Classic (ETC) address on the Ethereum Classic network in Trust Wallet. The address returned is identical to the one for the BEP20 network, which is incorrect since these networks operate on different protocols and should generate distinct addresses.

Hello @danilkharlan! Do you mind sharing steps to reproduce?

[danilkharlan]

1)Connect trust wallet
2)Call get address
3)I got ETC address for BEP20 network,but user can set Etherium Classic network and addresses it this networks is different

How i can specify network when call get address

[quetool]

But have you added Ethereum Classic network in your dapp in the list of supported networks? Have you switched to it? See docs https://docs.reown.com/appkit/flutter/core/custom-chains

From your steps it feels to me that you connect with Ethereum by default and you just then call getAddress(), therefor you get Ethereum address.

getAddress() is relative to the current selected netowork in your DApp.

selectedChain value is 61 that equal to Etherium clasic network,but I get BEP20 address(

Can you share your code?

[danilkharlan]

showLoader();
    final network = SupportedNetwork.getNetworkFor(
      assetCode: state.assetNetworkModel!.assetCode,
      networkCode: state.assetNetworkModel!.networkCode,
    );
    if (network != null) {
      final res = await getIt<IReownService>().changeNetwork(network);
    }

    final address = getIt<IReownService>().getWalletAddress();

    emitAction(CryptoWithdrawalAction.updateAddress(address, walletType));
    
    
    
    @override
  Future<void> changeNetwork(SupportedNetwork network) async {
    if (!isConnected) return;

    try {
     if (_appKitModal.selectedChain?.chainId == network.chainID) return;
      final chain = ReownAppKitModalNetworks.getNetworkById(
          NetworkUtils.eip155, network.chainID ?? '');
      await _appKitModal.selectChain(chain, switchChain: true);
      _appKitModal.launchConnectedWallet();
      final chainId = int.tryParse(network.chainID ?? '0');
      final result = await _appKitModal.request(
        topic: _appKitModal.session!.topic,
        chainId: _appKitModal.selectedChain!.chainId,
        request: SessionRequestParams(
          method: MethodsConstants.walletSwitchEthChain,
          params: [
            {'chainId': '0x${chainId?.toRadixString(16)}'}
          ],
        ),
      );
    } catch (e) {
      _streamController.addError(e);
    }
  }
  
  
   @override
  String getWalletAddress() =>
      _appKitModal.session?.getAddress(NetworkUtils.eip155) ?? '';
      

[quetool]

But are you adding Ethereum Classic to ReownAppKitModalNetworks before initializing AppKitModal?

[danilkharlan]

Here is my init method.Is it correct?

void init({required BuildContext context}) async {
    if (_isInitialized) return;

     ReownAppKitModalNetworks.addSupportedNetworks(
        NetworkUtils.eip155,
        ReownConstants.supportedNetworks,
      );

    _appKitModal = ReownAppKitModal(
      context: context,
      projectId: ReownConstants.projectId,
      enableAnalytics: true,
      logLevel: LogLevel.debug,
      includedWalletIds: {
        ReownConstants.trustWalletId,
        ReownConstants.metaMaskWalletId,
      },
      metadata: PairingMetadata(
        name: ReownConstants.appName,
        description: 'Mobile app',
        url: """",
        icons: [""""],
        redirect: Redirect(native: """""),
      ),
    );

    // Set up listeners for modal events
    _appKitModal.onModalConnect.subscribe((ModalConnect? event) {
      notifyListeners('onModalConnect');
      _onConnect?.call();
    });
    _appKitModal.onModalUpdate
        .subscribe((ModalConnect? event) => notifyListeners('onModalUpdate'));
    _appKitModal.onModalNetworkChange.subscribe(
        (ModalNetworkChange? event) => notifyListeners('onModalNetworkChange'));
    _appKitModal.onModalDisconnect.subscribe(
        (ModalDisconnect? event) => notifyListeners('onModalDisconnect'));
    _appKitModal.onModalError
        .subscribe((ModalError? event) => notifyListeners('onModalError'));
    _appKitModal.onSessionExpireEvent.subscribe(
        (SessionExpire? event) => notifyListeners('onSessionExpireEvent'));
    _appKitModal.onSessionUpdateEvent.subscribe(
        (SessionUpdate? event) => notifyListeners('onSessionUpdateEvent'));
    _appKitModal.onSessionEventEvent.subscribe(
        (SessionEvent? event) => notifyListeners('onSessionEventEvent'));
    _appKitModal.appKit!.core.relayClient.onRelayClientConnect.subscribe(
        (EventArgs? event) => notifyListeners('onRelayClientConnect'));
    _appKitModal.appKit!.core.relayClient.onRelayClientError
        .subscribe((EventArgs? event) => notifyListeners('onRelayClientError'));
    _appKitModal.appKit!.core.relayClient.onRelayClientDisconnect.subscribe(
        (EventArgs? event) => notifyListeners('onRelayClientDisconnect'));

    try {
      await _appKitModal.init();
      final list = _appKitModal.appKit?.authKeys.storage.getAll() as List<Map>?;
      if (selectedWallet == null) {
        for (final map in list ?? []) {
          final listing = map['listing'];
          if (listing != null) {
            final info = ReownAppKitModalWalletInfo.fromJson(map);
            _appKitModal.selectWallet(info);
            _appKitModal.reconnectRelay();
          }
        }
      }

      _isInitialized = true;
      notifyListeners('isInitialized');
    } catch (e) {
      notifyListeners('isInitialized');
    }
  }

Thanks! Can you explain again the issue? Cause as far as I know Ethereum Classica and Ethereum Mainnet uses the same address format. Furthermore, the addresses depending on the network are given by the connected wallet (Trust in this case) and not by AppKit. I'm a bit lost, sorry...

[danilkharlan]

Yes,you are right!
In looks weird,but ETC has different addresses in networks...

[quetool]

Have you tried a different wallet? Maybe it's just a Trust issue?

[danilkharlan]

In metamask the same addresses,but in trust different
can you handle it?

[quetool]

Sorry, seems to be an issue on Trust side. We, as AppKit don't mange neither keys nor addresses. Essentially we just allow secure communication between dapp and wallet but keys (therefor addresses) are always on wallet side. You can try opening an issue to them https://github.com/trustwallet maybe?

[danilkharlan]

ill investigate it and will back soon
