方案一: 通过 ExinCore API 进行币币交易
Exincore 提供了基于 Mixin Network 的币币交易 API.
你可以支付 USDT 给 ExinCore, ExinCore 会以最低的价格,最优惠的交易费将你购买的比特币转给你, 每一币交易都是匿名的,并且可以在区块链上进行验证,交易的细节只有你与 ExinCore 知道!
ExinCore 也不知道你是谁,它只知道你的 UUID.
预备知识:
你先需要创建一个机器人, 方法在 教程一.
安装依赖包
正如教程一里我们介绍过的,我们需要依赖 mixin-bot, 你应该先安装过它了,这儿我们再安装 easy-uuid, msgpack 两个软件包.
gem install msgpack
gem install easy-uuid
充币到 Mixin Network, 并读出它的余额.
ExinCore 可以进行 BTC, USDT, EOS, ETH 等等交易,这儿演示如果用 USDT 购买 BTC 或者 用 BTC 购买 USDT, 交易前,先检查一下钱包地址!
完整的步骤如下:
- 检查比特币或 USDT 的余额,钱包地址。并记下钱包地址。
- 从第三方交易所或者你的冷钱包中,将币充到上述钱包地址。
- 再检查一下币的余额,看到帐与否。(比特币的到帐时间是 5 个区块的高度,约 100 分钟)。
请注意,比特币与 USDT 的地址是一样的。
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
查询 ExinCore 市场的价格信息
如果来查询 ExinCore 市场的价格信息呢?你要先了解你交易的基础币是什么,如果你想买比特币,卖出 USDT, 那么基础货币就是 USDT; 如果你想买 USDT, 卖出比特币,那么基础货币就是比特币.
if cmd == "8"
Utils.ExinCoreMarketPriceRequest(USDT_ASSET_ID)
end
if cmd == "9"
Utils.ExinCoreMarketPriceRequest(BTC_ASSET_ID)
end
def self.ExinCoreMarketPriceRequest(asset_id)
full_url = "https://exinone.com/exincore/markets?base_asset=" + asset_id
p full_url
data = HTTP.get(full_url).body
body = ""
redData = data.readpartial
while redData != nil
body = body + redData
redData = data.readpartial
end
result = ActiveSupport::JSON.decode(body).with_indifferent_access
result["data"].each { |x|
puts x["exchange_asset_symbol"] + "/" + x["base_asset_symbol"] + " " +
x["price"] + "" + x["minimum_amount"] +" "+ x["maximum_amount"] +" "+ x["exchanges"][0]
}
end
交易前,创建一个 Memo!
在第二章里, 基于 Mixin Network 的 Ruby 比特币开发教程: 机器人接受比特币并立即退还用户, 我们学习过退还用户比特币,在这里,我们除了给 ExinCore 支付币外,还要告诉他我们想购买的币是什么,即将想购买的币存到 memo 里。
memo1 = Base64.encode64(MessagePack.pack({'A' => UUID.parse(USDT_ASSET_ID).to_raw
}))
memo = memo1.sub("\n","")
币币交易的完整流程
转币给 ExinCore 时,将 memo 写入你希望购买的币, 这个 memo 别错了,否则,ExinCore 需要人工操作来退币!
如果你想卖出比特币买入 USDT, 调用方式如下:
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 memo
transInfo = 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
如果你想卖出 USDT 买入比特币, 调用方式如下:
if cmd == "6"
memo1 = Base64.encode64(MessagePack.pack({'A' => UUID.parse(BTC_ASSET_ID).to_raw
}))
memo = memo1.sub("\n","")
p memo
transInfo = 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
交易完成后,Exincore 会将你需要的币转到你的帐上,同样,会在 memo 里,记录成交价格,交易费用等信息!你只需要按下面的方式解开即可!
- read_snapshots 读取钱包的交易记录。
if cmd == "7"
if wallet_userid == "5e4ad097-21e8-3f6b-98f7-9dc74dd99f77"
dt = "2019-05-23T09:48:04.582099Z"
else
puts "Input the snapshots datetime:"
dt = gets.chomp
end
p 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 > 0
if x["data"] != nil
uData = MessagePack.unpack(Base64.decode64(x["data"]))
p uData
p "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_s
p "Order id is" + UUID.parse(uData["O"]).to_s
end
end
}
end
一次成功的交易如下:
Make your choose(eg: q for Exit!):

"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"
-------------------------------------------------------------------------
读取币的余额
通过读取币的余额,来确认交易情况!
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
