Getting the following error
"Web3Exception: RPC returned error for "eth_call": -32000 err: insufficient funds for gas * price + value: address 0xB65f5Ac5eAD9598f7Ec61c8C89033B970dA7B77D have 0 want 748486779400000000 (supplied gas 50000000)

But can check balance using Remix Ide.

public async void BalanceOf()
    {
        var balance = await Web3Accessor.Web3.Erc20.GetBalanceOf(
            "0x24383f6AC03b6B43ae95CFb83C88762Af1e142E8",

        Debug.Log("Balance of : "+ balance);
    }

Were you able to resolve this issue ? Was also facing this similar issue

#

we have an issue for this already i think

#

these two are tied together, feel free to comment on it 🙂
https://github.com/ChainSafe/web3.unity/issues/908
we should have it resolved soon.

This happens even on BSC main net & polygon mainnet

are you trying to do it on webgl by any chance?

terse delta are you trying to do it on webgl by any chance?

I am only testing inside Editor.

terse delta Jul 23, 2024, 4:16 AM

#

ok good, solves that possiblity

#

just have to wait for the issue to be resolved in the next release

rustic sparrow Jul 23, 2024, 4:18 AM

terse delta just have to wait for the issue to be resolved in the next release

When can we get the next release?

Or can we import the GitHub code to use now ?

i mean if it was fixed, sure

#

but it's not fixed yet unfortunately

Oh got it!!

once the issue above closes with a solution you should be able to

rustic sparrow Jul 24, 2024, 5:44 AM

#

Balance checking is working fine. If the required chain is set correctly in ProjectConfigData file inside resources folder.
Sometimes Server settings menu don't save if just select chain and close window without any other edit.

You can also check this once.

it should auto save on any change, @robust vault

rustic sparrow Jul 24, 2024, 4:41 PM

I am trying to switch network just by logging out, and destroying the Web3Accessor and Destroying WalletConnectDialog.
And again Calling Initialize of LoginProvider after changing the ProjectConfigData, wallet is connecting successfully, but I think chain is not changing, because new chain token balance is always shown as 0.

Is there any quick solution for this ?

Are you passing the right contract address

rustic sparrow Jul 24, 2024, 5:50 PM

#

robust vault Are you passing the right contract address

Yes

robust vault Jul 24, 2024, 5:50 PM

#

You can check if the chain is correct by debug logging the webe.chainconfig.chainId

Yes I have also checked that, the chain is correct.

But the balance is 0, if first time initialized with another chain.

robust vault Jul 24, 2024, 5:59 PM

#

Can you give me the snippet of your code, and the address to the contract, as well as the chain config, would like to test it out

rustic sparrow Jul 25, 2024, 2:36 AM

#

robust vault Can you give me the snippet of your code, and the address to the contract, as we...

public class WalletConnectLoginProviderDD : LoginProviderDD, IWeb3BuilderServiceAdapter
{
    [SerializeField] private WalletConnectConfigSO walletConnectConfig;
    
    [SerializeField] private Button loginButton;
    private void OnEnable()
    {
        loginButton.onClick.AddListener(Initialize);
    }

    protected override void Initialize()
    {
        base.Initialize();
        OnLoginClicked();
    }

    public Web3Builder ConfigureServices(Web3Builder web3Builder)
    {
        return web3Builder.Configure(services =>
        {
            services.UseWalletConnect(walletConnectConfig)
                .UseWalletConnectSigner()
                .UseWalletConnectTransactionExecutor();
        });
    }

    private async void OnLoginClicked()
    {
        await TryLogin();
    }
}

I am using this Custom Script for Wallet Connect Logic.
I am calling the Initialize() when Connect button will be clicked, not on start, so that it can be initialized with selected chain. LoginProviderDD class is same as LoginProvider class without the Start function.

At first I am setting Binance Mainnet on ProjectConfigData (ScriptableObject) inside Resources folder.
Clicking on Connect Button, it is being initialized with Binance Mainnet and connecting Wallet and Showing Balance as 0. It's okay because the token is deployed on another chain.
Now I am disconnecting wallet by Calling

await Web3Accessor.TerminateAndClear(logout: true);

Destroying Web3Accessor gameobject and WalletConnect Dialog in the scene.
Setting ProjectConfigData again for Cardona Testnet,
Clicking on connect button, so again initializing and connecting wallet.
Debug log is showing chain as Cardona, but the balance of the token is 0 again. It should show 960.

But if we at first set as Cardona and initialize and connect, the showing correct balance.

#

My token is on Cardona Testnet (chain id 2442) and contract address is 0x24383f6AC03b6B43ae95CFb83C88762Af1e142E8

And this wallet 0xB65f5Ac5eAD9598f7Ec61c8C89033B970dA7B77D
has 960 of the above token.

rustic sparrow Jul 25, 2024, 3:41 AM

#

The first selected chain balance is always showing even we change chain in ProjectConfigData resource file and Initialize again. Even not showing any error.

robust vault Jul 25, 2024, 6:36 AM

#

Setting ProjectConfigData again for Cardona Testnet,
How are you setting the projectconfigdata

#

like while you are in the unity game you are directly changing your scriptable object in the editor itself?

Checked both.

robust vault Jul 25, 2024, 8:51 AM

#

Can you send that code snippet when you actually change the chain ? If you are doing it dynamically

rustic sparrow Jul 25, 2024, 8:51 AM

#

One minute

#

private void NetworkChanged(ChainDetails chainDetails)
    {
        Debug.Log("Network Changed to " + chainDetails.chainName);
        currentChainDetails = chainDetails;
        //chainConfigResource = chainDetails.chainConfig;
        chainConfigResource.Chain = chainDetails.chainConfig.Chain;
        chainConfigResource.ChainId = chainDetails.chainConfig.ChainId;
        chainConfigResource.Network = chainDetails.chainConfig.Network;
        chainConfigResource.Symbol = chainDetails.chainConfig.Symbol;
        chainConfigResource.Rpc = chainDetails.chainConfig.Rpc;

    }

#

Here is the full Script

using ChainSafe.Gaming.UnityPackage;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Numerics;
using UnityEngine;

public class BlockchainManager : MonoBehaviour
{
    [SerializeField] private ProjectConfigScriptableObject chainConfigResource;


    private void OnEnable()
    {
        NetworkSlider.OnNetworkChainChanged += NetworkChanged;
    }
    private void OnDisable()
    {
        NetworkSlider.OnNetworkChainChanged -= NetworkChanged;
    }


    public static BlockchainManager Instance;
    private void Awake()
    {
        if(Instance != null && Instance != this)
        {
            Destroy(gameObject);
        }
        Instance = this;
        
       
    }
    private void NetworkChanged(ChainDetails chainDetails)
    {
        Debug.Log("Network Changed to " + chainDetails.chainName);
        currentChainDetails = chainDetails;
        //chainConfigResource = chainDetails.chainConfig;
        chainConfigResource.Chain = chainDetails.chainConfig.Chain;
        chainConfigResource.ChainId = chainDetails.chainConfig.ChainId;
        chainConfigResource.Network = chainDetails.chainConfig.Network;
        chainConfigResource.Symbol = chainDetails.chainConfig.Symbol;
        chainConfigResource.Rpc = chainDetails.chainConfig.Rpc;
    }
}

[Serializable]
public class ChainDetails
{
    public ChainName chainName;
    public Sprite chainIcon;
    public ProjectConfigScriptableObject chainConfig;

}

public enum ChainName
{
    BSC_Main,
    Polygon_Main,
    Test
}

#

Here I have created ProjectConfig scriptable objects and passing for selected chain

#

chainConfigResource is the reference for ProjectConfigData inside resources folder. And this is being updated succesfully.

robust vault Jul 25, 2024, 1:38 PM

#

Aha so you just use it like Resources.Load<PRojectConfigScriptableObject>("NAME");

#

Got it

rustic sparrow Jul 25, 2024, 2:46 PM

#

robust vault Aha so you just use it like Resources.Load<PRojectConfigScriptableObject>("NAME"...

Okay I'll use like that.

But how to solve the checking balance after chain switching issue?

robust vault Jul 25, 2024, 3:39 PM

#

I will try to fix the issue for the upcoming release of the sdk in the next week

#

Since tomorrow is company-wide day off

#

So will keep you updated

Thank you very much!!

rustic sparrow Jul 25, 2024, 4:12 PM

robust vault I will try to fix the issue for the upcoming release of the sdk in the next week

But you can also give me any idea if I can do anything on my side to do it.

Can you check maybe if the rpc is also correct

rustic sparrow Jul 29, 2024, 6:22 AM

Yes RPC is correct
