We have created a bot to echo message and echo Bitcoin.
- How to create Bitcoin wallet
- How to read Bitcoin balance
- How to send Bitcoin with zero transaction fee and confirmed in 1 second
- How to send Bitcoin to other wallet
Pre-request: You should have a Mixin Network account. Create an account can be done by one line code:
userInfo = mixinApiBotInstance.createUser(session_key.decode(),"Tom Bot")The function in Python SDK create a RSA key pair automatically, then call Mixin Network to create an account. last the function return all account information.
//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"),Result of createUser is:
{'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'}}Now you need to carefully keep the account information. You need these information to read asset balance and other content.
The Bitcoin wallet is not generated automatically at same time when we create Mixin Network account. Read Bitcoin asset once to generate a Bitcoin wallet.
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")))You can found information about Bitcoin asset in the account. Public key is the Bitcoin deposit address. Full response of read Bitcoin asset is
{'data': {'type': 'asset', 'asset_id': 'c6d0c728-2624-429b-8e0d-d9d19b6592fa',

'confirmations': 12, 'capitalization': 0}}The API provide many information about Bitcoin asset.
- Deposit address:[public_key]
- Logo: [icon_url]
- Asset name:[name]
- Asset uuid in Mixin network: [asset_key]
- Price in USD from Coinmarketcap.com: [price_usd]
- Least confirmed blocks before deposit is accepted by Mixin network:[confirmations]
Where is Bitcoin private key? The private key is protected by multi signature inside Mixin Network so it is invisible for user. Bitcoin asset can only be withdraw to other address when user provide correct RSA private key signature, PIN code and Session key.
The account not only contain a Bitcoin wallet, but also contains wallet for Ethereum, EOS, etc. Full blockchain support list. All ERC20 Token and EOS token are supported by the account.
Create other asset wallet is same as create Bitcoin wallet, just read the asset.

If you read EOS deposit address, the deposit address is composed of two parts: account_name and account tag. When you transfer EOS token to your account in Mixin network, you should fill both account name and memo. The memo content is value of 'account_tag'. Result of read EOS asset is:
{'data': {'type': 'asset', 'asset_id': '6cfe566e-4aad-470b-8c9a-2fd35b49c68d',
'chain_id': '6cfe566e-4aad-470b-8c9a-2fd35b49c68d',

'confirmations': 64, 'capitalization': 0}}Now you can deposit Bitcoin into the deposit address.
This is maybe too expensive for this tutorial. There is a free and lightening fast solution to deposit Bitcoin: add the address in your Mixin messenger account withdrawal address and withdraw small amount Bitcoin from your account to the address. It is free and confirmed instantly because they are both on Mixin Network.
Now you can read Bitcoin balance of the account.
btcInfo = mixinApiNewUserInstance.getAsset("c6d0c728-2624-429b-8e0d-d9d19b6592fa");
print(btcInfo);Any transaction happen between Mixin network account is free and is confirmed in 1 second.
We can send Bitcoin to our bot through Mixin Messenger, and then transfer Bitcoin from bot to new user.
mixinApiBotInstance = MIXIN_API(mixin_config)
//$user_info["user_id"] generated by create user;
mixinApiBotInstance.transferTo(userid, BTC_ASSET_ID, AMOUNT, "")Read bot's Bitcoin balance to confirm the transaction. Caution: mixinApiNewUserInstance is for the New User!
def readAssetBalance(asset_id):
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("Account %s \'s balance is %s " %(userid,btcInfo.get("data").get("balance")))If you want to send Bitcoin to another exchange or wallet, you need to know the destination deposit address, then add the address in withdraw address list of the Mixin network account.
Pre-request: Withdrawal address is added and know the Bitcoin withdrawal fee
Call createAddress, the ID of address will be returned in result of API and is required soon.
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)The 14T129GTbXXPGXXvZzVaNLRFPeHXD1C25C is a Bitcoin wallet address, Output like below, The API result contains the withdrawal address ID, fee is 0.0034802 BTC.

'updated_at': '2019-02-26T00:03:05.028140704Z'}}If you want create a EOS address, call it like below:
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)Submit the withdrawal request to Mixin Network, the btcInfo.get("data").get("address_id") is the address id it's return by createAddress
mixinApiBotInstance.withdrawals(btcInfo.get("data").get("address_id"),AMOUNT,"")
