如何将 Mixin Network 的比特币提现到你的冷钱包或第三方交易所.

前期准备：你要有一个 Mixin Network 账户。下面的代码创建一个帐号，并写到 csv 文件里。

if File.file?(WALLET_NAME)
  p "mybitcoin_wallet.csv has already existed !"
  next
end
yaml_hash = YAML.load_file('./config.yml')

MixinBot.client_id  = yaml_hash["MIXIN_CLIENT_ID"]
MixinBot.session_id = yaml_hash["MIXIN_SESSION_ID"]
MixinBot.client_secret = yaml_hash["MIXIN_CLIENT_SECRET"]
MixinBot.pin_token   = yaml_hash["MIXIN_PIN_TOKEN"]
MixinBot.private_key = yaml_hash["MIXIN_PRIVATE_KEY"]

access_token = MixinBot.api.access_token("GET","/","")

rsa_key = OpenSSL::PKey::RSA.new(1024)
private_key = rsa_key.to_pem()
p private_key
public_key = rsa_key.public_key.to_pem
secret_client = public_key.sub("-----BEGIN PUBLIC KEY-----\n","").sub("\n-----END PUBLIC KEY-----\n","")
reqInfo = MixinBot.api.create_user("ruby bot",secret_client)
p reqInfo["data"]["pin_token"]
p reqInfo["data"]["user_id"]
p reqInfo["data"]["session_id"]


CSV.open(WALLET_NAME, "wb") do |csv|
  csv << [private_key, reqInfo["data"]["pin_token"], reqInfo["data"]["session_id"], reqInfo["data"]["user_id"]]
end

上面的语句会在本地创建一个 RSA 密钥对，然后调用 Mixin Network 来创建帐号，最后保存帐号信息到 csv 文件.

现在你需要小心保管好你的帐号信息，在读取该账户的比特币资产余额或者进行其他操作时，将需要用到这些信息.

新账号并不默认内置比特币钱包，现在读一下比特币余额就可以创建一个比特币钱包。

if cmd == "2"
  table = CSV.read(WALLET_NAME)
  MixinBot.client_id = table[0][3]
  MixinBot.session_id = table[0][2]
  MixinBot.pin_token = table[0][1]
  MixinBot.private_key = table[0][0]
  botAssetsInfo = MixinBot.api.read_asset(BTC_ASSET_ID)
  p botAssetsInfo
  p "The BTC wallet address is" + botAssetsInfo["data"]["public_key"]
  p "The BTC wallet balance is" + botAssetsInfo["data"]["balance"]
end

创建的帐号的比特币资产详细信息如下，其中 public key 就是比特币的存币地址:

Make your choose(eg: q for Exit!):

"chain_id"=>"c6d0c728-2624-429b-8e0d-d9d19b6592fa", "symbol"=>"BTC",
 "name"=>"Bitcoin", "icon_url"=>"https://images.mixin.one/HvYGJsV5TGeZ-X9Ek3FEQohQZ3fE9LBEBGcOcn4c4BNHovP4fW4YB97Dg5LcXoQ1hUjMEgjbl1DPlKg1TW7kK6XP=s128",

 "confirmations"=>6, "capitalization"=>0}}
"The BTC wallet address is 1MQLQG1FshdVaQrDE36FLGabCitE3vPUA"
"The BTC wallet balance is 0"
-------------------------------------------------------------------------

这个 API 能够提供若干与比特币有关的信息:

存币地址:[public_key]
Logo: [icon_url]
资产名字:[name]
资产在 Mixin Network 的 uuid: [asset_key]
对美元的价格 (Coinmarketcap.com 提供): [price_usd]
存币时确认的区块数量:[confirmations]

比特币的私钥呢？这个私钥被 Mixin Network 通过多重签名保护，所以对用户来说是不可见的, 比特币资产的提现和转账都需要用户提供正确的的 RSA 签名,PIN 代码与会话密钥才能完成.

这个帐号不只支持比特币，还支持以太坊，EOS 等, 完整的区块链支持列表. 这个账户同时也支持所有的 ERC20 代币与 EOS 代币.

创建其它的币的钱包与创建比特币钱包过程一样，读对应的资产余额就可以.

EOS 的存币地址与其它的币有些不同，它由两部分组成：account_name and account tag, 如果你向 Mixin Network 存入 EOS，你需要填两项数据：account name 是 eoswithmixin, 备注里输入你的 account_tag, 比如 0aa2b00fad2c69059ca1b50de2b45569.

EOS 的资产余额返回结果如下:

现在，你可以向比特币的钱包存币了。

当然，在比特币网络里转币，手续费是相当贵的，费用的中位数在 0.001BTC, 按当前 4000 美元的价格，在 4 美元左右，有一个方便的办法，如果你有 Mixin Messenger 帐号，里面并且有比特币的话，可以直接提现比特币到新创建的帐号的比特币充值地址，它们在同一个 Mixin Network 网络内，手续费为 0，而且 1 秒到账。

下面的代码，可以读取比特币钱包余额.

table = CSV.read(WALLET_NAME)
MixinBot.client_id = table[0][3]
MixinBot.session_id = table[0][2]
MixinBot.pin_token = table[0][1]
MixinBot.private_key = table[0][0]
botAssetsInfo = MixinBot.api.read_asset(BTC_ASSET_ID)
p botAssetsInfo
p "The BTC wallet address is" + botAssetsInfo["data"]["public_key"]
p "The BTC wallet balance is" + botAssetsInfo["data"]["balance"]

任何币在 Mixin Network 内部的交易，都是无手续费的，并且立刻到账。
前期准备：账户设置了 PIN

对于新创建的帐号，我们通过 updatePin 来设置新 PIN 码, 代码如下：

table = CSV.read(WALLET_NAME)
puts table[0][1]
MixinBot.client_id = table[0][3]
MixinBot.session_id = table[0][2]
MixinBot.pin_token = table[0][1]
MixinBot.private_key = table[0][0]
pinInfo = MixinBot.api.update_pin('',DEFAULT_PIN)
p pinInfo

通过 Mixin Messenger，我们可以先转比特币给机器人，然后让机器人转币给新用户。

if cmd == "teb"
  yaml_hash = YAML.load_file('./config.yml')

  MixinBot.client_id  = yaml_hash["MIXIN_CLIENT_ID"]
  MixinBot.session_id = yaml_hash["MIXIN_SESSION_ID"]
  MixinBot.client_secret = yaml_hash["MIXIN_CLIENT_SECRET"]
  MixinBot.pin_token   = yaml_hash["MIXIN_PIN_TOKEN"]
  MixinBot.private_key = yaml_hash["MIXIN_PRIVATE_KEY"]
  table = CSV.read(WALLET_NAME)
  wallet_userid = table[0][3]
  botAssetsInfo = MixinBot.api.read_asset(EOS_ASSET_ID)
  if botAssetsInfo["data"]["balance"].to_f > 0
    transInfo = MixinBot.api.create_transfer(MixinBot.api.encrypt_pin(yaml_hash["MIXIN_PIN_CODE"]),
                                      {
                                        asset_id: EOS_ASSET_ID,
                                        opponent_id: wallet_userid,
                                        amount: botAssetsInfo["data"]["balance"],
                                        trace_id: SecureRandom.uuid,
                                        memo: "from ruby"
                                      })
    p transInfo
 end
end

读取 Bitcoin 的余额，来确认比特币是不是转成功了！

    botAssetsInfo = MixinBot.api.read_assets()

如果你希望将币存入你的冷钱包或者第三方交易所, 先要得到冷钱包或者你在第三方交易所的钱包地址，然后将钱包地址提交到 Mixin Network.

要点提示 : 提现是需要支付收续费的, 准备好比特币包地址!

调用 createAddress API, 将会返回一个 address_id, 下一步的提现操作会用到这个 id。

if cmd == "wb"
  table = CSV.read(WALLET_NAME)
  MixinBot.client_id = table[0][3]
  MixinBot.session_id = table[0][2]
  MixinBot.pin_token = table[0][1]
  MixinBot.private_key = table[0][0]
  addressInfo = MixinBot.api.create_withdraw_address(BTC_ASSET_ID,
                                                       DEFAULT_PIN,
                                                       BTC_WALLET_ADDR,
                                                       "","",
                                                       "from ruby")
  p addressInfo
  p "The address id is" + addressInfo["data"]["address_id"] + "it is needed by read fee!"
end

这里的 14T129GTbXXPGXXvZzVaNLRFPeHXD1C25C 就是一个比特币钱包地址, 如下所示，提现费用是 0.0025738 BTC, address_id 是 ”345855b5-56a5-4f3b-ba9e-d99601ef86c1″.

The BTC withdraw fee  is 0.00118846

  addressInfo = MixinBot.api.get_withdraw_address(addressInfo["data"]["address_id"])
  p addressInfo

提交提现请求到 Mixin Network, withdrawAddress.address_id 就是 createAddress 创建的。

if cmd == "wb"
  table = CSV.read(WALLET_NAME)
  MixinBot.client_id = table[0][3]
  MixinBot.session_id = table[0][2]
  MixinBot.pin_token = table[0][1]
  MixinBot.private_key = table[0][0]
  addressInfo = MixinBot.api.create_withdraw_address(BTC_ASSET_ID,
                                                       DEFAULT_PIN,
                                                       BTC_WALLET_ADDR,
                                                       "","",
                                                       "from ruby")
  p addressInfo
  p "The address id is" + addressInfo["data"]["address_id"] + "it is needed by read fee!"
  addressInfo2 = MixinBot.api.del_withdraw_address(addressInfo["data"]["address_id"], DEFAULT_PIN)
  p addressInfo2

  withdrawInfo = MixinBot.api.withdrawals(addressInfo["data"]["address_id"],
                                          DEFAULT_PIN,
                                          "0.1",
                                          SecureRandom.uuid,"from ruby")
  p withdrawInfo
end
