In the wallet side, is it possible to specify the chain that will be chosen on Dapp side?

[SametSahin10]

I've integrated this package into my Flutter app and it's working well. However, I just have a question about specifying the chain to use. In our mobile app, we connect to a Dapp that supports three chains: Fuse, Ethereum, Binance. When the wallet is connected to the Dapp via WalletConnect, Ethereum is chosen by default. Is there a way to specify which chain to choose after connecting?

Hello! I don't quite understand, are you developing a Wallet or a dApp? A bit more of clarification would be helpful.

In any case, the way a dApp "specifies the network" is by calling wallet_switchEthereumChain (or wallet_addEthereumChain if the current connected wallet has not approved the network). This request will make the wallet to change the "current working network"

Could you teach me how to make transactions with a Metamask in Flutter? I need help when I try to interact with the smart contract between Metamask and my app. I am using the package 'web3modal_flutter/web3modal_flutter.dart'. After approving my app, how can I interact with user's metamask, for ex: I want the user click on my send button, and they can send 0.001 eth to the address that they chose

My code:

final w3mService = W3MService( projectId: '123', metadata: const PairingMetadata( name: 'New App', description: 'WalletConnect', url: 'https://www.walletconnect.com/', icons: [ 'https://avatars.githubusercontent.com/u/37784886' ], redirect: Redirect( native: 'flutterdapp://', universal: 'https://www.walletconnect.com', ), ), );

await w3mService.init();

await w3mService .openModal(context);

Please @Mash-Woo open a discussion or refer to docs. Also you are commenting in the wrong repo.

I'm working on a wallet app @quetool but the Dapp is also our product. So, we're able to make changes on both sides. What we need is to choose Fuse network on Dapp when the wallet is connected via WC. Which side should take care of this? Dapp or Wallet?

When the wallet is connected to the Dapp via WalletConnect, Ethereum is chosen by default. Is there a way to specify which chain to choose after connecting?

Hello @SametSahin10, sorry for the delay. After connection you can call wallet_switchEthereumChain from your dApp so your Wallet can change to your desired chain, right? Maybe I misunderstood your issue?
