摘要：下面的代碼，可以讀取比特幣錢包余額網(wǎng)內(nèi)免手續(xù)費(fèi)的，并且即時確認(rèn)任何幣在內(nèi)部的交易，都是無手續(xù)費(fèi)的，并且立刻到賬。

我們已經(jīng)創(chuàng)建過一個回復(fù)消息的機(jī)器人和一個能自動支付比特幣的機(jī)器人.

如何創(chuàng)建一個比特幣錢包.

如何讀取比特幣錢包的余額.

如何實(shí)現(xiàn)免手續(xù)費(fèi)支付比特幣并1秒到賬

如何將Mixin Network的比特幣提現(xiàn)到你的冷錢包或第三方交易所.

前期準(zhǔn)備：你要有一個Mixin Network賬戶。如果沒有賬戶，一行代碼就能創(chuàng)建一個

  userInfo = mixinApiBotInstance.createUser(session_key.decode(),"Tom Bot")

上面的語句會在本地創(chuàng)建一個RSA密鑰對，然后調(diào)用Mixin Network來創(chuàng)建帳號，最后輸出帳號信息.

//Create User api include all account information
userInfo.get("data").get("pin_token"),
userInfo.get("data").get("session_id"),
userInfo.get("data").get("user_id"),

帳號創(chuàng)建成功后結(jié)果如下:

{"data": {"type": "user", "user_id": "2f25b669-15e7-392c-a1d5-fe7ba43bdf37",
"identity_number": "0", "full_name": "Tom Bot", "avatar_url": "",
"relationship": "", "mute_until": "0001-01-01T00:00:00Z",
"created_at": "2019-02-22T06:23:41.754573722Z", "is_verified": False,
"session_id": "284c7b39-3284-4cf6-9354-87df30ec7d57", "phone": "",
"pin_token": "g4upUgBXa8ATk7yxL6B94HgI4GV4sG4t8Wyn6uTu2Q2scH11UMQ5bYDb6Md+3LRQqRjEdRFcLlHijXGBihRweTaKTZjHQqolWbZcffesVIias6WppV/QMu4TzXCuKa5xpj3uhjL+yPyfWTLGUaVJTJN9n7PQmHSIUBXrovbfodk=",
"invitation_code": "", "code_id": "", "code_url": "", "has_pin": False,
"receive_message_source": "EVERYBODY", "accept_conversation_source": "EVERYBODY"}}

現(xiàn)在你需要小心保管好你的帳號信息，在讀取該賬戶的比特幣資產(chǎn)余額或者進(jìn)行其他操作時，將需要用到這些信息.

新賬號并不默認(rèn)內(nèi)置比特幣錢包， 現(xiàn)在讀一下比特幣余額就可以創(chuàng)建一個比特幣錢包。

def readAssetAddress(asset_id,isBTC = True):
    with open("new_users.csv", newline="") as csvfile:
        reader  = csv.reader(csvfile)
        for row in reader:
            pin         = row.pop()
            userid      = row.pop()
            session_id  = row.pop()
            pin_token   = row.pop()
            private_key = row.pop()
            mixinApiNewUserInstance = generateMixinAPI(private_key,
                                                        pin_token,
                                                        session_id,
                                                        userid,
                                                        pin,"")
            btcInfo = mixinApiNewUserInstance.getAsset(asset_id)
            print(btcInfo)
            if isBTC:
                print("Account %s "s Bitcoin wallet address is %s  " %(userid,btcInfo.get("data").get("public_key")))
            else:
                print("Account %s "s EOS account name is %s, wallet address is %s  " %(userid,
                                                                        btcInfo.get("data").get("account_name"),
                                                                        btcInfo.get("data").get("account_tag")))

創(chuàng)建的帳號的比特幣資產(chǎn)詳細(xì)信息如下，其中public key就是比特幣的存幣地址:

{"data": {"type": "asset", "asset_id": "c6d0c728-2624-429b-8e0d-d9d19b6592fa",
"chain_id": "c6d0c728-2624-429b-8e0d-d9d19b6592fa",

"account_name": "", "account_tag": "", "price_btc": "1",
"price_usd": "3879.88117389", "change_btc": "0",
"change_usd": "0.017333475714793264",
"asset_key": "c6d0c728-2624-429b-8e0d-d9d19b6592fa",
"confirmations": 12, "capitalization": 0}}
Account a8cefb2e-cb93-338f-aba7-32a3a635ad02 "s Bitcoin wallet address is 12sJHR7HJPMt33KwSHyxQvYqGGUEbVGREf

這個API能夠提供若干與比特幣有關(guān)的信息:

存幣地址:[public_key]

Logo: [icon_url]

資產(chǎn)名字:[name]

資產(chǎn)在Mixin Network的uuid: [asset_key]

對美元的價格(Coinmarketcap.com提供): [price_usd]

存幣時確認(rèn)的區(qū)塊數(shù)量:[confirmations]

比特幣的私鑰呢？這個私鑰被Mixin Network通過多重簽名保護(hù)，所以對用戶來說是不可見的,比特幣資產(chǎn)的提現(xiàn)和轉(zhuǎn)賬都需要用戶提供正確的的RSA簽名,PIN代碼與會話密鑰才能完成.

這個帳號不只支持比特幣，還支持以太坊，EOS等, 完整的區(qū)塊鏈支持列表. 這個賬戶同時也支持所有的 ERC20 代幣與 EOS 代幣.

創(chuàng)建其它的幣的錢包與創(chuàng)建比特幣錢包過程一樣，讀對應(yīng)的資產(chǎn)余額就可以.

EOS的存幣地址與其它的幣有些不同，它由兩部分組成： account_name and account tag, 如果你向Mixin Network存入EOS，你需要填兩項(xiàng)數(shù)據(jù)： account name 是eoswithmixin,備注里輸入你的account_tag,比如0aa2b00fad2c69059ca1b50de2b45569.

EOS的資產(chǎn)余額返回結(jié)果如下:

{"data": {"type": "asset", "asset_id": "6cfe566e-4aad-470b-8c9a-2fd35b49c68d",
"chain_id": "6cfe566e-4aad-470b-8c9a-2fd35b49c68d",
"symbol": "EOS", "name": "EOS",
"icon_url": "https://images.mixin.one/a5dtG-IAg2IO0Zm4HxqJoQjfz-5nf1HWZ0teCyOnReMd3pmB8oEdSAXWvFHt2AJkJj5YgfyceTACjGmXnI-VyRo=s128",
"balance": "0", "public_key": "",
"account_name": "eoswithmixin", "account_tag": "70dae97b661ca9f80cb0e6549feeba6c",
"price_btc": "0.00092392", "price_usd": "3.58276497",

"asset_key": "eosio.token:EOS", "confirmations": 64, "capitalization": 0}}
Account a8cefb2e-cb93-338f-aba7-32a3a635ad02 "s EOS account name is eoswithmixin, wallet address is 70dae97b661ca9f80cb0e6549feeba6c

現(xiàn)在，你可以向比特幣的錢包存幣了。

當(dāng)然，在比特幣網(wǎng)絡(luò)里轉(zhuǎn)幣，手續(xù)費(fèi)是相當(dāng)貴的，費(fèi)用的中位數(shù)在0.001BTC,按當(dāng)前4000美元的價格，在4美元左右，有一個方便的辦法，如果你有Mixin Messenger帳號，里面并且有比特幣的話，可以直接提現(xiàn)比特幣到新創(chuàng)建的帳號的比特幣充值地址，它們在同一個Mixin Network網(wǎng)絡(luò)內(nèi)，手續(xù)費(fèi)為0，而且1秒到賬。

下面的代碼，可以讀取比特幣錢包余額.

btcInfo = mixinApiNewUserInstance.getAsset(asset_id)
print("Account %s "s balance is %s  " %(userid,btcInfo.get("data").get("balance")))

任何幣在Mixin Network內(nèi)部的交易，都是無手續(xù)費(fèi)的，并且立刻到賬。
前期準(zhǔn)備： 賬戶設(shè)置了PIN

對于新創(chuàng)建的帳號，我們通過updatePin來設(shè)置新PIN碼, 代碼如下：

pinInfo = mixinApiNewUserInstance.updatePin(PIN,"")
print(pinInfo)

通過Mixin Messenger，我們可以先轉(zhuǎn)比特幣給機(jī)器人，然后讓機(jī)器人轉(zhuǎn)幣給新用戶。

mixinApiNewUserInstance = generateMixinAPI(private_key,
                                            pin_token,
                                            session_id,
                                            userid,
                                            pin,"")
btcInfo = mixinApiBotInstance.transferTo(MASTER_UUID, BTC_ASSET_ID, AMOUNT, "")
print(btcInfo)

讀取Bitcoin的余額，來確認(rèn)比特幣是不是轉(zhuǎn)成功了！ 注意$mixinSdkNew是新用戶的。

btcInfo = mixinApiNewUserInstance.getAsset(asset_id)
print("Account %s "s balance is %s  " %(userid,btcInfo.get("data").get("balance")))

如果你希望將幣存入你的冷錢包或者第三方交易所, 先要得到冷錢包或者你在第三方交易所的錢包地址，然后將錢包地址提交到Mixin Network.

要點(diǎn)提示: 提現(xiàn)是需要支付收續(xù)費(fèi)的,準(zhǔn)備好比特幣包地址!

調(diào)用createAddress API, 將會返回一個address_id,下一步的提現(xiàn)操作會用到這個id。

BTC_ASSET_ID    = "c6d0c728-2624-429b-8e0d-d9d19b6592fa";
EOS_ASSET_ID    = "6cfe566e-4aad-470b-8c9a-2fd35b49c68d";
BTC_WALLET_ADDR = "14T129GTbXXPGXXvZzVaNLRFPeHXD1C25C";
btcInfo = mixinApiBotInstance.createAddress(BTC_ASSET_ID, BTC_WALLET_ADDR,"BTC","","")
print(btcInfo)

這里的 14T129GTbXXPGXXvZzVaNLRFPeHXD1C25C 就是一個比特幣錢包地址, 如下所示，提現(xiàn)費(fèi)用是0.0034802 BTC, address_id 是"345855b5-56a5-4f3b-ba9e-d99601ef86c1".

{"data": {"type": "address",
"address_id": "47998e2f-2761-45ce-9a6c-6f167b20c78b",
"asset_id": "c6d0c728-2624-429b-8e0d-d9d19b6592fa",
"public_key": "14T129GTbXXPGXXvZzVaNLRFPeHXD1C25C", "label": "BTC",
"account_name": "", "account_tag": "",
"fee": "0.0034802", "reserve": "0", "dust": "0.0001",
"updated_at": "2019-02-26T00:03:05.028140704Z"}}

如果你操作的是EOS, 示例代碼如下：

EOS_ASSET_ID     = "6cfe566e-4aad-470b-8c9a-2fd35b49c68d";
EOS_WALLET_ADDR  = "3e2f70914c8e8abbf60040207c8aae62";
EOS_ACCOUNT_NAME = "eoswithmixin";
eosInfo = mixinApiBotInstance.createAddress(EOS_ASSET_ID, "","",EOS_ACCOUNT_NAME,EOS_WALLET_ADDR)
print(eosInfo)

addr_id = btcInfo.get("data").get("address_id")
addrInfo = mixinApiBotInstance.getAddress(addr_id)
print(addrInfo)

提交提現(xiàn)請求到Mixin Network, $btcInfo["address_id"]就是createAddress創(chuàng)建的。

  mixinApiBotInstance.withdrawals(btcInfo.get("data").get("address_id"),AMOUNT,"")
