iWan is the "interface to Wanchain", which provide users with secure, dependable access to the full array of Wanchain full node services, including the Wanchain main network and test network. Through the API and developer tools provided by iWan, developers now have access to both native Wanchain and cross chain services including cross chain transactions, account management, smart contract querries, and much more. iWan provides the core Wanchain interface for developers so that they can focus on building their business layer without worrying about the cost and complexity of setting up their own full node.
