The contract address will be printed on the console and save the contract address in your file！

--- approve.js

This approve.js can help you authorize the airdrop contract address to use your specified number of tokens from your account; you need set 'amount','airdropApproveAddress','userPrivateKey' and 'tokenContractAddress' then run approve.js , it will print the txHash and transfer result;

--- airdrop.js

This airdrop.js is an executive document of the airdrop contract.

parameters: 'filePath':your airdrop address file,and i am using the *.xlsx 'addressIndex': this means the index of eth address in your *.xlsx, 'amountIndex': this means the index of token amount in your *.xlsx, 'addressNeedJudgeRepeat': this parameter represents whether you want to filter duplicate addresses.

--- execute.js

The airdrop sequence is as follows:

1. Deploy ERC20Token contract and airdrop contract.
2. Approve enough ERC20 tokens to the airdrop contract.
3. Compile a list of reciepient addresses and store them in 'airdropList.txt' file.
4. Run 'start.js' script.
5. You can look the airdrop result on the console or check the txHash in 'https://etherscan.io';

If you are not familiar with the smart contract, then follow the steps below!

1. run npm install
2. Config your userPrivateKey and other info in config.js
3. Run deploy.js , then you will get the result on console
4. copy the contractAddress on the console, and paste it in config.js ->approveModule->airdropApproveAddress
5. Config your tokenContractAddress and userPrivateKey in config.js ->approveModule. this userPrivateKey is the private key of the account which you want to use for transfer token;
6. Run approve.js, then your will get the result on console .
7. The address and number of airdrop will be required to be listed in xlsx.
8. Run 'start.js' script.
9. You can check the airdrop result on the console or check the txHash in 'https://etherscan.io'.
