hiveengine
hiveengine is a python library for working with hive-engine.com tokens.
I released version 0.1.3 which can be installed by
pip install hiveengine
hiveengine is using beem for broadcasting transfers and custom_json to the HIVE blockchain. hiveengine is only working when using HIVE nodes. You can check the currently set nodes with
beem config
Hive nodes can be set with
beem updatenodes --hive
API
hiveengine is using the following API endpoint: https://api.hive-engine.com/rpc/ . For depositing HIVE inside hiveengine, HIVE is send to @honey-swap. For all other operations, custom_jsons with the ssc-mainnet-hive id are broadcast.
CLI tool
The packages comes with a command line tool which can be used with parameters or in shell mode when no parameter is set.
shell mode
hiveengine
starts it and you have now the following commands:
Starting hiveengine... (use help to list all commands)
hiveengine>
buy cancel-unstake help quit sellbook unstake
buybook deposit info richlist stake withdraw
cancel exit issue sell transfer
normal mode
Append a command to use hiveengine in normal mode, e.g.:
hiveengine info
Usage
Latest block
Get the latest block of the side-chain
from hiveengine.api import Api
api = Api()
latest_block = api.get_latest_block_info()
The command line tool can also be used:
hiveengine info
returns
+--------------------------+---------------------+
| Key | Value |
+--------------------------+---------------------+
| latest block number | 5435 |

| virtualTransactions | 1 |
| Number of created tokens | 57 |
+--------------------------+---------------------+
Specific side-chain block
Get the block with the specified block number of the side-chain
from hiveengine.api import Api
api = Api()
print(api.get_block_info(1000))
or with CLI
hiveengine info 1000
Specific transaction trx
Retrieve the specified transaction info of the side-chain. The number behind the - sign selects an operation when there are more than one transaction inside a transaction.

Contracts
Get the contract specified from the database
from hiveengine.api import Api
api = Api()
print(api.get_contract("tokens"))
Find information about tokens
Get an array of objects that match the query from the table of the specified contract
from hiveengine.api import Api
api = Api()
print(api.find("tokens", "tokens"))
Get the object that matches the query from the table of the specified contract
from hiveengine.api import Api
api = Api()
print(api.find("tokens", "tokens", query={"symbol": "BEE"}))
or with CLI:
hiveengine info FOODIE
Token: FOODIE
+------------------------+-----------------+
| Key | Value |
+------------------------+-----------------+
| _id | 33 |
| issuer | foodiesunite |
| symbol | FOODIE |
| name | Foodies Bee Hive|
| metadata_url | foodiesunite.net|
...
Receive token holder
from hiveengine.api import Api
api = Api()
print(api.find("tokens", "balances", query={"symbol": "BEE"}))
This can also be done with the tokenobject class:
from hiveengine.tokenobject import Token
token = Token("BEE")
print(token.get_holder())
or with CLI:
hiveengine richlist BEE

Buybook
from hiveengine.api import Api
api = Api()
print(api.find("market", "buyBook", query={"symbol": "BEE"}))
or by using the market class:
from hiveengine.market import Market
market = Market()
print(market.get_buy_book("BEE"))
or with CLI:
hiveengine buybook BEE
+----------+---------------+---------------+------------+

Sellbook
from hiveengine.api import Api
api = Api()
print(api.find("market", "sellBook", query={"symbol": "BEE"}))
or by using the market class:
from hiveengine.market import Market
market = Market()
print(market.get_sell_book("BEE"))
or with CLI:
hiveengine sellbook BEE

Transfering/Staking and Unstaking token
The wallet object can be used to transfer/stake/unstake token:
from hiveengine.wallet import Wallet
from beem import Steem
from beem.nodelist import NodeList
import getpass
nodelist = NodeList()
nodelist.update_nodes()
active_wif = getpass.getpass("active wif: ")
stm = Steem(node=nodelist.get_hive_nodes(), keys=[active_wif])
account = stm.wallet.getAccountFromPrivateKey(active_wif)
wallet = Wallet(account, steem_instance=stm)
wallet.transfer("holger80", 1, "FOODIE", "test")
wallet.stake(1, "FOODIE")
wallet.stake(1, "FOODIE", receiver="holger80")
wallet.unstake(1, "FOODIE")
wallet.cancel_unstake("faa0af0e27dd4ebe036fd90f36b354e6e1360221")
This can also be done with the CLI
hiveengine transfer -a beembot holger80 1 FOODIE test
hiveengine stake -a beembot 1 FOODIE
hiveengine stake -a beembot -r holger80 1 FOODIE
hiveengine unstake -a beembot 1 FOODIE
hiveengine cancel-unstake -a beembot faa0af0e27dd4ebe036fd90f36b354e6e1360221
Market operation
The market object can be used for market operation
from hiveengine.market import Market
from beem import Steem
from beem.nodelist import NodeList
import getpass
nodelist = NodeList()
nodelist.update_nodes()
active_wif = getpass.getpass("active wif: ")
stm = Steem(node=nodelist.get_hive_nodes(), keys=[active_wif])
account = stm.wallet.getAccountFromPrivateKey(active_wif)
market = Market(steem_instance=stm)
print(market.get_metrics()) # returns all tokens
print(market.get_buy_book("BEE"))
print(market.get_sell_book("BEE"))
market.withdraw(account, 1) # withdraw 1 SWAP.HIVE
market.deposit(account, 1)# transfer 1 HIVE to honey-swap
market.buy(account, 1, "BEE", 0.9) # place buy order for 1 BEE for 0.9 HIVE/BEE
market.sell(account, 1 "BEE", 1.1) # place sell order for 1 BEE for 1.1 HIVE/BEE
market.cancel(account, "buy", 12) # cancel buy order with id 12
These operation can also be performed with the CLI:
hiveengine withdraw -a beembot 1
hiveengine deposit -a beembot 1
hiveengine buy -a beembot 1 BEE 0.9
hiveengine sell -a beembot 1 BEE 1.1
hiveengine cancel -a beembot buy 12
