Ethereum.Blazor.Metamask

This project is based on https://github.com/Nethereum/Nethereum.Metamask.Blazor

TODO

• Add custom tokens (ERC20, ERC721, etc.)
• Make this package a little bit easier to install, by removing js script import statement from index.html (load script in .net runtime)

How to install

1.Download the package from NuGet

2.Place this script import into header of index.html file <script src="_content/Ethereum.Blazor.Metamask/EthereumMetamaskIterop.js"></script>

3.Register the necessary service in Progra.cs builder.Services.AddBlazorMetamask();

4.Wrap all components with <Metamask>...</Metamask> in App.razor file

How to use

The regular flow of using this package is looks like this

1.Check for metamask availability bool isAvailable = await _ethereumHostProvider.IsMetamaskAvailableAsync(); If its not avalaible, ask user to install the Metamask

2.Check, if user attached Metamask to your Dapp: bool isConnected = await _ethereumHostProvider.IsMetamaskConnectedAsync();

3.Enable provider. Allways call this method to initially load users selected account: string selectedAccount await _ethereumHostProvider.EnableProviderAsync(); If user previosly didnt attached his Metamask account, calling this method will triger Metamask account selection

4.Optional. Subscribe on on SelectedAccountChanged and NetworkChanged events to handle user iteraction with Metamask

AT THAT TIME TESTED ONLY ON BLAZOR WASM
