 3) 获取二进制对象  
 在上一步编译成功的 solidity 对象里面包含很多的属性/值, 而我们需要的是其中合约对象的二进制, abi 属性值. 如下, 我们通过属性提取方式进行获取. solidity 对象的其他属性可以通过代码调试方式进行调试, 这里不再赘述. 
 ```js
-const contractFile = tempFile.contracts["Incrementer.sol"]["Incrementer"];
+const contractFile = compiledCode.contracts["Incrementer.sol"]["Incrementer"];
 
 // Get bin & abi
 const bytecode = contractFile.evm.bytecode.object;

-8) 交易签名 
-如下使用私钥对交易进行签名,
-```js
-// Sign Tx
-const deployTransaction = await web3.eth.accounts.signTransaction(

 这里使用发送签名后的交易到区块链网络, 同时会去返回的交易回执. 从返回的交易回执中可以得到此次部署的合约的地址
