方案一: 通過ExinCore API進行幣幣交易

Exincore 提供了基于Mixin Network的幣幣交易API.

你可以支付USDT給ExinCore, ExinCore會以最低的價格，最優(yōu)惠的交易費將你購買的比特幣轉給你, 每一幣交易都是匿名的，并且可以在區(qū)塊鏈上進行驗證，交易的細節(jié)只有你與ExinCore知道！

ExinCore 也不知道你是誰，它只知道你的UUID.

預備知識:

你先需要創(chuàng)建一個機器人, 方法在 教程一.

安裝依賴包

正如教程一里我們介紹過的， 我們需要依賴 mixin-bot, 你應該先安裝過它了， 這兒我們再安裝 easy-uuid, msgpack 兩個軟件包.

gem install msgpackgem install easy-uuid 復制代碼

充幣到 Mixin Network, 并讀出它的余額.

ExinCore可以進行BTC, USDT, EOS, ETH 等等交易， 這兒演示如果用 USDT購買BTC 或者 用BTC購買USDT, 交易前，先檢查一下錢包地址！ 完整的步驟如下:

• 檢查比特幣或USDT的余額，錢包地址。并記下錢包地址。
• 從第三方交易所或者你的冷錢包中，將幣充到上述錢包地址。
• 再檢查一下幣的余額，看到帳與否。(比特幣的到帳時間是5個區(qū)塊的高度，約100分鐘)。

請注意，比特幣與USDT的地址是一樣的。

if cmd == "aw"assetsInfo = walletAccount.read_assets()p "--------The Wallet Assets List-----------------"assetsInfo["data"].each { |x| puts x["symbol"] + " " +x["balance"] + " " + x["public_key"] +x["account_name"] + " " + x["account_tag"]}p "----------End of Wallet Assets --------------" end 復制代碼

查詢ExinCore市場的價格信息

如果來查詢ExinCore市場的價格信息呢？你要先了解你交易的基礎幣是什么，如果你想買比特幣，賣出USDT,那么基礎貨幣就是USDT;如果你想買USDT,賣出比特幣，那么基礎貨幣就是比特幣.

if cmd == "8"Utils.ExinCoreMarketPriceRequest(USDT_ASSET_ID) end if cmd == "9"Utils.ExinCoreMarketPriceRequest(BTC_ASSET_ID) enddef self.ExinCoreMarketPriceRequest(asset_id)full_url = "https://exinone.com/exincore/markets?base_asset=" + asset_idp full_urldata = HTTP.get(full_url).bodybody = ""redData = data.readpartialwhile redData != nilbody = body + redDataredData = data.readpartialendresult = ActiveSupport::JSON.decode(body).with_indifferent_accessresult["data"].each { |x|puts x["exchange_asset_symbol"] + "/" + x["base_asset_symbol"] + " " +x["price"] + " " + x["minimum_amount"] + " " + x["maximum_amount"] +" " + x["exchanges"][0]} end 復制代碼

交易前，創(chuàng)建一個Memo!

在第二章里,基于Mixin Network的Ruby比特幣開發(fā)教程: 機器人接受比特幣并立即退還用戶, 我們學習過退還用戶比特幣，在這里，我們除了給ExinCore支付幣外，還要告訴他我們想購買的幣是什么，即將想購買的幣存到memo里。

memo1 = Base64.encode64(MessagePack.pack({ 'A' => UUID.parse(USDT_ASSET_ID).to_raw })) memo = memo1.sub("\n","") 復制代碼

幣幣交易的完整流程

轉幣給ExinCore時，將memo寫入你希望購買的幣, 這個memo別錯了，否則，ExinCore需要人工操作來退幣！ 如果你想賣出比特幣買入USDT,調(diào)用方式如下：

const EXIN_BOT = "61103d28-3ac2-44a2-ae34-bd956070dab1"; const BTC_ASSET_ID = "c6d0c728-2624-429b-8e0d-d9d19b6592fa"; const EOS_ASSET_ID = "6cfe566e-4aad-470b-8c9a-2fd35b49c68d"; const USDT_ASSET_ID = "815b0b1a-2764-3736-8faa-42d694fa620a"; if cmd == "5"memo1 = Base64.encode64(MessagePack.pack({'A' => UUID.parse(USDT_ASSET_ID).to_raw}))memo = memo1.sub("\n","")p memotransInfo = walletAccount.create_transfer(walletAccount.encrypt_pin(DEFAULT_PIN),{asset_id: BTC_ASSET_ID,opponent_id: EXIN_BOT,amount: "0.0001",trace_id: SecureRandom.uuid,memo: memo})p transInfo end 復制代碼

如果你想賣出USDT買入比特幣,調(diào)用方式如下：

if cmd == "6"memo1 = Base64.encode64(MessagePack.pack({'A' => UUID.parse(BTC_ASSET_ID).to_raw}))memo = memo1.sub("\n","")p memotransInfo = walletAccount.create_transfer(walletAccount.encrypt_pin(DEFAULT_PIN),{asset_id: USDT_ASSET_ID,opponent_id: EXIN_BOT,amount: "1",trace_id: SecureRandom.uuid,memo: memo})p transInfo end 復制代碼

交易完成后，Exincore會將你需要的幣轉到你的帳上，同樣，會在memo里，記錄成交價格，交易費用等信息！你只需要按下面的方式解開即可！

• read_snapshots 讀取錢包的交易記錄。

if cmd == "7"if wallet_userid == "5e4ad097-21e8-3f6b-98f7-9dc74dd99f77"dt = "2019-05-23T09:48:04.582099Z"elseputs "Input the snapshots datetime: "dt = gets.chompendp CGI.escape(dt)snaps = walletAccount.read_snapshots({limit: "10",offset: CGI.escape(dt),asset: BTC_ASSET_ID,order: "ASC"})snaps["data"].each { |x|if x["amount"].to_f > 0if x["data"] != niluData = MessagePack.unpack(Base64.decode64(x["data"]))p uDatap "The code is " + uData["C"].to_s + " Price is " + uData["P"] + " Fee is " +uData["F"]p "Fee is Asset UUID is " + UUID.parse(uData["FA"]).to_sp "Order id is " + UUID.parse(uData["O"]).to_sendend} end 復制代碼

一次成功的交易如下：

Make your choose(eg: q for Exit!): 7 "2019-05-23T09%3A48%3A04.582099Z" {"C"=>1000, "P"=>"7562.91", "F"=>"0.000000264", "FA"=>"\xC6\xD0\xC7(&$B\x9B\x8E\r\xD9\xD1\x9Be\x92\xFA", "T"=>"R", "O"=>"\xC4\x00*\a\xF1\xB1C9\xBC\xCE%\xC3C\x88^R"} "The code is 1000 Price is 7562.91 Fee is 0.000000264" "Fee is Asset UUID is c6d0c728-2624-429b-8e0d-d9d19b6592fa" "Order id is c4002a07-f1b1-4339-bcce-25c343885e52" ------------------------------------------------------------------------- 復制代碼

讀取幣的余額

通過讀取幣的余額，來確認交易情況！

if cmd == "aw"assetsInfo = walletAccount.read_assets()p "--------The Wallet Assets List-----------------"assetsInfo["data"].each { |x| puts x["symbol"] + " " +x["balance"] + " " + x["public_key"] +x["account_name"] + " " + x["account_tag"]}p "----------End of Wallet Assets --------------" end 復制代碼
