Wallet Connectivity

IEthereumHostProvider is the universal interface that every wallet connection in Nethereum implements. It is the shared foundation for the Wallet SDK, Web (Blazor) dApp Integration, and Unity sections.

All providers share the same interface — GetWeb3Async(), EnableProviderAsync(), SignMessageAsync(), SelectedAccountChanged, NetworkChanged — so application code works identically regardless of which wallet is connected.
