CryptoCountries.io高阶技巧1 - 使用MyEtherWallet(MEW)从后台直接购买国家

D小游

文/吴尼克

MyEtherWallet是以太坊主流钱包之一，可以用来和智能合约直接进行交互。由于CryptoCountries刚上新的时候，会有众多玩家一起抢购。很容易导致前端更新缓慢。如果想要更快出价的话，可以直接通过MyEtherWallet进行后台交互。

操作流程：

1至11步为准备流程，请在打新之前准备好。

12步及之后是打新重要步骤，请做到眼疾手快。

1、打开https://www.myetherwallet.com/#contracts

2、把这里的Gas Price 调整到合适的位置，建议30以上。不贪的兄弟可以参考ethgasstation里fast的gas price。

3、

Contract Address里填写CryptoCountries的合约地址：0x92cB5F1FbabbcbDd891B9Cbd8E9a056c8c1eEbEF

4、复制以下文字到ABI/JSON INTERFACE

[{"constant":true,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"tokenExists","outputs":[{"name":"_exists","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_amount","type":"uint256"}],"name":"withdrawAmount","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"_name","type":"string"}],"payable":false,"stateMutability":"pure","type":"function"},{"constant":false,"inputs":[{"name":"_to","type":"address"},{"name":"_itemId","type":"uint256"}],"name":"approve","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"implementsERC721","outputs":[{"name":"_implements","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_owner","type":"address"}],"name":"setOwner","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"_admin","type":"address"}],"name":"removeAdmin","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"_totalSupply","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_itemRegistry","type":"address"}],"name":"setItemRegistry","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"_from","type":"address"},{"name":"_to","type":"address"},{"name":"_itemId","type":"uint256"}],"name":"transferFrom","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"_admin","type":"address"}],"name":"isAdmin","outputs":[{"name":"_isAdmin","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"approvedFor","outputs":[{"name":"_approved","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"allOf","outputs":[{"name":"_owner","type":"address"},{"name":"_startingPrice","type":"uint256"},{"name":"_price","type":"uint256"},{"name":"_nextPrice","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"listItemFromRegistry","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"_itemId","type":"uint256"},{"name":"_price","type":"uint256"},{"name":"_owner","type":"address"}],"name":"listItem","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"_from","type":"uint256"},{"name":"_take","type":"uint256"}],"name":"itemsForSaleLimit","outputs":[{"name":"_items","type":"uint256[]"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"_owner","type":"address"}],"name":"tokensOf","outputs":[{"name":"_tokenIds","type":"uint256[]"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"nextPriceOf","outputs":[{"name":"_nextPrice","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"ownerOf","outputs":[{"name":"_owner","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"_price","type":"uint256"}],"name":"calculateDevCut","outputs":[{"name":"_devCut","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_admin","type":"address"}],"name":"addAdmin","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"_owner","type":"address"}],"name":"balanceOf","outputs":[{"name":"_balance","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[],"name":"enableERC721","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[],"name":"withdrawAll","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"_itemIds","type":"uint256[]"}],"name":"populateFromItemRegistry","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"symbol","outputs":[{"name":"_symbol","type":"string"}],"payable":false,"stateMutability":"pure","type":"function"},{"constant":false,"inputs":[{"name":"_to","type":"address"},{"name":"_itemId","type":"uint256"}],"name":"transfer","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"startingPriceOf","outputs":[{"name":"_startingPrice","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"priceOf","outputs":[{"name":"_price","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_itemIds","type":"uint256[]"},{"name":"_price","type":"uint256"},{"name":"_owner","type":"address"}],"name":"listMultipleItems","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"_itemId","type":"uint256"}],"name":"buy","outputs":[],"payable":true,"stateMutability":"payable","type":"function"},{"constant":true,"inputs":[{"name":"_price","type":"uint256"}],"name":"calculateNextPrice","outputs":[{"name":"_nextPrice","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_itemId","type":"uint256"},{"indexed":true,"name":"_owner","type":"address"},{"indexed":false,"name":"_price","type":"uint256"}],"name":"Bought","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_itemId","type":"uint256"},{"indexed":true,"name":"_owner","type":"address"},{"indexed":false,"name":"_price","type":"uint256"}],"name":"Sold","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_from","type":"address"},{"indexed":true,"name":"_to","type":"address"},{"indexed":false,"name":"_tokenId","type":"uint256"}],"name":"Transfer","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_owner","type":"address"},{"indexed":true,"name":"_approved","type":"address"},{"indexed":false,"name":"_tokenId","type":"uint256"}],"name":"Approval","type":"event"}]

5、点access

6、这里拉到下面选buy

7、这里选新出来的国家的编号。国家的编号如何查看可以通过监测智能合约管理者的地址来看。但是需要做一下16进制到10进制的转换。具体在后面说。

8、选择第一个MetaMask/Mist

然后connect to MetaMask

9、点write

10、非常关键的一步。Amount写你认为这个国家可以卖到的最高价的前一个价格。比如你认为新出的这个国家可以卖到1eth，那你就写0.7。如果想稳赚，请尽量保守，比如只填1的一半0.5。土豪随意。

Gas limit
应该会自动跳出来。不跳就300000

11、Generate transaction

至此已经完成了准备工作

12、这一步至关重要。点击Yes, I am sure!然后马上再回来，重复11步和12步2-5次。意思是向后台服务器连续发送2-5次购买指令。这样做的目的是为了可以和对手盘反复成交，炒作新的国家。吃掉预期价格前的所有利润空间。

特别注意：如果metamask出现错误，请reject，返回重新再试一次。在出现错误的时候请切勿发出命令！出现错误的迹象如下：

1、Gas Limit超级高，高于100万。

2、出现Transaction error的提示

如何看新出国家的编号

还是群里问吧，方法有点复杂。。。
