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;

6) 构造合约实例

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(
{
data: deployTx.encodeABI(),
gas: 8000000,
},
account_from.privateKey
);

9) 部署合约
8) 部署合约
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
```js
const deployReceipt = await web3.eth.sendSignedTransaction(
deployTransaction.rawTransaction
);
console.log(`Contract deployed at address: ${deployReceipt.contractAddress}`);
const tx = await deployTx.send({
from: accounts[0].address,
gas,
// gasPrice: 10000000000,
});
```
