# 利用Layer3任务获得ENS域名，几乎0花费 By [Mr Wick空投日记](https://paragraph.com/@mraw8888) · 2022-09-24 --- 本教程适用于那些没有ens域名，没做过这个L3任务的人。可以让你以最少的成本获得更多的收益！ ---------------------------------------------- ### 对于小号来说非常的划算，既获得了ens域名（包括反向解析）交互了主网数据，顺带完成了Layer3的5个任务.涉及到跨链.主网 arb 马蹄三个网络的交互，让每一步交互都不浪费，环环相扣 **推特**[@MrAW8888](https://twitter.com/MrAW8888) **思路整理不易 记得一键三连转发关注哦！** **1.第一步资金，交易所提到arb 把这个任务交互了 （主网没钱的可以顺带交互下这个任务，主网有钱的不想浪费跨链费跳过）** 任务链接： [https://beta.layer3.xyz/bounties/deep-defi-on-arbitrum](https://beta.layer3.xyz/bounties/deep-defi-on-arbitrum)

[https://opensea.io/zh-CN/collection/ens?search\[sortAscending\]=true&search\[sortBy\]=UNIT\_PRICE](https://opensea.io/zh-CN/collection/ens?search%5BsortAscending%5D=true&search%5BsortBy%5D=UNIT_PRICE) 我们随便选一个域名，价格在0.0011差不多1.47u ![](https://storage.googleapis.com/papyrus_images/5ac4be74051f90bf987c240d8a1e26d31ae6dad37b93ec6044f49b0f463d292f.png) 复制红框内的域名名字去ENS上去查什么时候到期 快到期的我们不买！ [ ENS --- Your identity across web3, one name for all your crypto addresses, and your decentralised website. https://app.ens.domains ![](https://storage.googleapis.com/papyrus_images/9a3c736c74add3351afbea8d0f29453183b9b04751f15e4cd599edead22db987.png) ](https://app.ens.domains/) 复制进去查询，像这种灰色的 2023年9月还有一年才到期的直接回到op里直接付款买就行了 ![](https://storage.googleapis.com/papyrus_images/91fbecae18033ebf2bdade88acae12ed0b35bf3e2c5573dfa45a53e725d5cff4.png) 记得调gas 5.8-7都行 一起花费2.8u ![](https://storage.googleapis.com/papyrus_images/06a5d6cc652d214925682ce0d70e5404ff73ca3a4b8c4f1b54566ffa2fc3e26d.png) 买完之后再回到ENS应用上.点左上角链接钱包 [ ENS --- Your identity across web3, one name for all your crypto addresses, and your decentralised website. https://app.ens.domains ![](https://storage.googleapis.com/papyrus_images/9a3c736c74add3351afbea8d0f29453183b9b04751f15e4cd599edead22db987.png) ](https://app.ens.domains/) ![](https://storage.googleapis.com/papyrus_images/17e209d298266ce03b9843e1147461b6e7785213c6b7c6c347c9c8734631b2c7.png) 再点右上角进入我都域名 ![](https://storage.googleapis.com/papyrus_images/f68ad1d3233a8c05792ffa910ee1c06856d64c72e4388f2e0822e983095a1b23.png) 进入之后可以看到是没有反向解析的，我们先点击这里 ![](https://storage.googleapis.com/papyrus_images/2c3742f1e12ee6af90e416d4f65e3040b95d6d0d6d8c065dab1e7836dd98720b.png) 进去看到注册人跟控制器地址不一致，点击2去更改 ![](https://storage.googleapis.com/papyrus_images/205d24c9f22b6b171be948cd23c585efbe79593fb4741ff8b12ee5cbd9095deb.png) 地址填自己钱包地址 也就是注册人地址 花费0.4u ![](https://storage.googleapis.com/papyrus_images/ff227ffbb8a5a5e19923b367e705afb7f63f90f1f9f5cf9b758ba05c68ff83db.png) 点击这个添加自己地址 ![](https://storage.googleapis.com/papyrus_images/4c4abf6e85b04b72636cef337632d1f807944ae01b4c79a038cdb361958a4be5.png) 然后划到最下面确认 花费0.37u ![](https://storage.googleapis.com/papyrus_images/d638d2c72e53db193cf91c16cf0e8e94e90aa8ad4962ee633944e49fac09e3fb.png) 回到我的域名界面 反向解析 选择自己的域名 然后点击确定 花费0.98u ![](https://storage.googleapis.com/papyrus_images/eddc613d89043651a6a32fe9f92d30d9853860d877420a44ac46b7d40dfbc2f9.png) 这里可以把L3的子域名任务做了 花费0.5u 任务链接：

![](https://storage.googleapis.com/papyrus_images/6ae59bc0b581cf1e479c0c425cd91b342f8836c00d53e3029a32e0d6b78974cc.png) 做完这个任务再来做L3的主线任务 [https://beta.layer3.xyz/bounties/ens-holder-you-deserve-an-nft](https://beta.layer3.xyz/bounties/ens-holder-you-deserve-an-nft) ![](https://storage.googleapis.com/papyrus_images/6fce0cd7198ca01240178057e392b5ee5f4f6a8b4d0e9276c2a0db116467483d.png) 完成任务获得这个NFT 然后点这里 去opensea上把他卖了 ![](https://storage.googleapis.com/papyrus_images/2ae70dcfe12d0d0fef2275b45095ce72f5f45e030d2b471e5fd1dea77fe4e62a.png) ### 价格在5u附近不等 如果不做L3的跨链任务花费正好5u 做的话也就5.6u ![](https://storage.googleapis.com/papyrus_images/da736040b4e3f6683489de4975a1a8b50b455ad36126184272fc49a61e72ecae.png) 可以直接在opensea把售出ETH换成matic

[https://beta.layer3.xyz/bounties/intro-to-balancer-ii-staking-rewards](https://beta.layer3.xyz/bounties/intro-to-balancer-ii-staking-rewards) ![](https://storage.googleapis.com/papyrus_images/f9b7d2f25d887a1eceb26a6f06e32de0c5fc6c4ba842ce08cb600e13d6e4f406.png) ### 至此所有的教程就结束了，交互了Layer3的五个任务 获得了大量经验（新号的话够你生好几级了） 还拥有了带有反向解析的ENS域名+子域 花费在5u左右，卖掉的ENS 探索者nft正好抵消了花费，简直就是白嫖了一个ENS域名+L3的经验+主网 arb Polygon网络大量的链上交互数据.赚麻了！ **如果感到本文不错的话，欢迎各位看官老爷关注我的推特**[@MrAW8888](https://twitter.com/MrAW8888) 附上本人谷歌作业表格：
