Nethereum.Balances

Easily get all your token balances at https://balance.nethereum.com/

Nethereum features demonstrated

Nethereum now includes built in support to work with Multicall.sol, this enables much faster querying using many different functions from different smart contracts. Just use your FunctionMessages input and outputs.

  for (int i = startItem; i < totaItemsToFetch; i++)
            {
                var balanceOfMessage = new BalanceOfFunction() { Owner = account };
                var call = new MulticallInputOutput<BalanceOfFunction, BalanceOfOutputDTO>(balanceOfMessage,
                    _tokens[i].Address);
                callList.Add(call);
            }

            await _web3.Eth.GetMultiQueryHandler().MultiCallAsync(callList.ToArray()).ConfigureAwait(false);

            var currentBalances = new List<BalanceResult>();

            for (int i = startItem; i < totaItemsToFetch; i++)
            {

                var balance = ((MulticallInputOutput<BalanceOfFunction, BalanceOfOutputDTO>)callList[i - startItem]).Output.Balance;
                if (balance > 0)
                {
                    var balanceResult = new BalanceResult()
                    {
                        Balance = Web3.Web3.Convert.FromWei(balance, _tokens[i].Decimals),
                        TokenImage = _tokens[i].LogoURI,
                        TokenName = _tokens[i].Symbol,
                        TokenAdress = _tokens[i].Address,
                        GeckoToken = _geckoTokens.FirstOrDefault(x => x.Symbol.ToLower() == _tokens[i].Symbol.ToLower())
                    };

                    currentBalances.Add(balanceResult);
                }
            }

Future of the application

This will be later on integrated in the other apps, like Nethereum Desktop and Explorer / Wallet (web, mobile, desktop, etc)
