一、智能合约dapp开发技术简介智能合约dapp开发技术是一种基于区块链技术的开发技术，它可以帮助开发者构建出功能强大、可靠性高的dapp（去中心化应用）系统开发180.3831.97z4。
To deploy via Infura you'll need a wallet provider (like @truffle/hdwallet-provider)
* to sign your transactions before they're sent to a remote public node. Infura accounts
* are available for free at: infura.io/register.
*
* You'll also need a mnemonic - the twelve word phrase the wallet uses to generate
* public/private key pairs. If you're publishing your code to GitHub make sure you load this
* phrase from a file you've .gitignored so it doesn't accidentally become public.
