# 二层网络主流解决方案zksync-rollup的合约交互流程

一，前言 现在以太坊网络拥堵是人尽皆知的事情，钱包里面转100美金的，选择30分钟确认速度的矿工费居然也要20多美金了，defi的大爆发，各种应用在以太坊网络搭建，在2年以内，只要ETH2.0没有真正落地，以太坊网络拥堵将是常态。

以太坊网络是一层，类似中央银行，而在以太坊之外发展众多的小银行，每个小银行单独处理业务（作者蓝星），每个月提交一个汇总的借贷记录给中央银行，以此来减轻中央银行的工作压力，这些小银行就是二层网络。

现在主流的二层网络解决方案，主要就是两个，一个是optimism-rollup以及zksync-rollup，根据V神所说，中短期内，选择or，长期来看，zksync会胜出，那么我们现在要做的，就是去zksync合约上去花点手续费交互下。

目的就是看下zksync能否有空投，比如uni，早期在uni上交易过的地址，都获得了400个空投，另外一个就是看下zksync会否有IDO（现在OR以及Zksync都已经拿到了知名机构的超千万美金风投），早期合约交互过的地址（公众号：蓝星生财之道），有更大的概率可以获得白名单资格，毕竟这两个是明星项目了。

二，操作流程 1，必备工具：梯子，浏览器（谷歌或者brave），metamask钱包（即小狐狸钱包） 2, 打开谷歌浏览器，先安装好metamask钱包插件（直接搜索metamask然后选择浏览器插件下载就可以），创建ETH钱包，往钱包地址转入0.01个ETH，网络就选择以太坊主网。

3， 在浏览器地址栏输入 ： [https://zksync.io/](https://zksync.io/) , 记住，这个才是zksync的官方网址。 4， 点击open wallet， 图片: [https://uploader.shimo.im/f/Cf5SFEaSX7EnRmlW.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag\_abucJilFgemPWSPWojY](https://uploader.shimo.im/f/Cf5SFEaSX7EnRmlW.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag_abucJilFgemPWSPWojY)

在跳转页面选择metamask钱包， 图片: [https://uploader.shimo.im/f/SzG4WXCtYAMYdvdi.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag\_abucJilFgemPWSPWojY](https://uploader.shimo.im/f/SzG4WXCtYAMYdvdi.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag_abucJilFgemPWSPWojY)

在小狐狸页面点击sign in ，就是确认签名请求。 图片: [https://uploader.shimo.im/f/nTkTcnqXLkm47Lxp.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag\_abucJilFgemPWSPWojY](https://uploader.shimo.im/f/nTkTcnqXLkm47Lxp.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag_abucJilFgemPWSPWojY)

点击sign in 之后，会出现下面这张图，再点击deposit，就是将一层网络的资产存入到二层网络中去，如果你小狐狸钱包是转入了0.01个ETH，那个这里deposit的数量就是0.05个，因为要剩下一点ETH作为一层向二层转入的矿工费。

点击deposit之后会跳转到下面的页面，点击select，选择你要存入二层网络的代币，因为一层网络的钱包地址，我只转入了0.01个ETH，那么这里就只能选择ETH了。 图片: [https://uploader.shimo.im/f/COGG3Mfj7nyjaJZQ.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag\_abucJilFgemPWSPWojY](https://uploader.shimo.im/f/COGG3Mfj7nyjaJZQ.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag_abucJilFgemPWSPWojY)

一层网络上的矿工费(gas)还是太高了，转0.005个ETH，居然需要0.016个ETH作为矿工费,这意味着要完成这笔交易，我还得从imtoken钱包往小狐狸钱包再转点ETH过去。

新增ETH到小狐狸钱包之后，就可以从一层网络转到二层网络了，需要大概4分钟的时间进行区块确认。 图片: [https://uploader.shimo.im/f/Wm0rBEWKVW7rSo5u.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag\_abucJilFgemPWSPWojY](https://uploader.shimo.im/f/Wm0rBEWKVW7rSo5u.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag_abucJilFgemPWSPWojY) 图片: [https://uploader.shimo.im/f/drYtnM2ClomjYszW.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag\_abucJilFgemPWSPWojY](https://uploader.shimo.im/f/drYtnM2ClomjYszW.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag_abucJilFgemPWSPWojY)

点击OK，返回了如下图，可以看到二层网络有0.01个ETH了，可以点击Transfer进行转账，体验下二层网络转账的低手续费。

点击transfer之后，再点击select，然后再点击activate，需要先登记你的公钥地址，登记需要消耗11000gas，登记手续费大概是0.0047个ETH。 图片: [https://uploader.shimo.im/f/ncH0mOPjYmmBjRAs.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag\_abucJilFgemPWSPWojY](https://uploader.shimo.im/f/ncH0mOPjYmmBjRAs.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag_abucJilFgemPWSPWojY)

激活之后，就可以转账了(transfer)，但是刚开始你并没有联系人地址，可以去添加同样的二层网络的地址，也可以自己创建一个，或者邀请朋友创建一个。

二层网络激活了公钥地址，留点钱在二层网络，如果有空投，这个地址应当不会错过了。 图片: [https://uploader.shimo.im/f/09afZVRyNq9Ebek2.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag\_abucJilFgemPWSPWojY](https://uploader.shimo.im/f/09afZVRyNq9Ebek2.png!thumbnail?accessToken=eyJhbGciOiJIUzI1NiIsImtpZCI6ImRlZmF1bHQiLCJ0eXAiOiJKV1QifQ.eyJhdWQiOiJhY2Nlc3NfcmVzb3VyY2UiLCJleHAiOjE2MzcxNjUyNzIsImciOiJRd0NrZHZKeGhHeGdHdDZqIiwiaWF0IjoxNjM3MTY0OTcyLCJ1c2VySWQiOjEyNDg1MX0.9WY3QNXCaY9g1kPSWe5yYag_abucJilFgemPWSPWojY)
