领水使用教程

1.脚本使用yescaptcha过验证码，需要注册并获取key。没有的可以注册yescaptcha register。

2.将获取的key在faucet.py文件中替换232行中yes_key='XXX' 的XXX ，修改n为一次想要生成和领水的地址数量。

3.(新增）fuel龙头更新规则，同一ip重复领水将被拒绝，因此需要使用动态ip，已有在使用的动态ip经验的可直接配置242行。没有的可以注册使用nstproxy register.完成后在238行处替换nstproxy_Channel的XXX，239行处替换nstproxy_Password的XXX，删除238，239，240，241行的‘#‘，再删除掉242行即可，或者直接咨询所用代理的客服帮忙配置。

【注意】据反馈这个nstproxy动态代理区域似乎ip blocked的较多，可能是代理设置或者ip池较小原因，建议大家使用更有效的ip代理，如rola-ip，iproyal等。

4.在python3.10版本下运行 python3 faucet.py，如果显示Error：No module named 'XXX' ,请在cmd下运行 pip install XXX，如果是别的报错请自己查询谷歌或者百度，windows下似乎比较麻烦，涉及问题较多，大家自行尝试，mac和linux下运行较为顺畅。

5.运行完成后相关地址、私钥和助记词都会保存在fuel-wallet.txt文件中，请妥善保存。

import the mnemonic seed to fuel official wallet , get result

if you export private key from wallet, you will get same result

faucet

use yescaptcha to solver captcha

if you dont have YesCaptcha account yet, you can register here：yescaptcha register。

last but important!

1. test the result and compare it with main web wallet app(such as: metamask, mathwallet, trustwallet...) before you deposit crypto assets to the address
2. some wallet may get diffrent result, because it may use diffrent derive path to generate wallet
3. learn about hd-wallet principle by your self
