If you want to compile HSC, you should have the Aergo Lua Compiler(aergoluac)
Without it, you will face the error
$ python hsc_compile.py

ERROR: Cannot find AERGO_PATH for finding AERGO Lua Compiler (aergoluac)You can set the AERGO path manually

To deploy, you need to designate a target, private key. If not, the default target would be testnet of Aergo, and a private key will generate automatically.
$ python hsc_deploy.py --help
Usage: hsc_deploy.py [OPTIONS] COMMAND [ARGS]...
Options:
--target TEXT target AERGO for Horde configuration
--private-key TEXT the private key to create Horde Smart Contract. If
not set, it will be random
--waiting-time INTEGER the private key to create Horde Smart Contract
--help Show this message and exit.The default target is the testnet of Aergo, so you cannot deploy with 0 token for fee. Follow the instruction to top up your tokens.
$ python hsc_deploy.py

Not enough balance.
You need to request AERGO tokens on
https://faucet.aergoscan.io/
with the address:
AmLwYmhkFCh53fBSPJ25TCuezSFpBTu4M8uPWoP8j7LjupXeUYvW
And deploy again with the private key:
python hsc_deploy.py --private-key 6imerQYecKf8BqHNRQVqGuSoDS9BqDC3EtFtCXM5MPEZQySACEY
After deploying successfully, (in this example, I used locally installed and independent Aergo node)
$ python hsc_deploy.py --target localhost:7845

Prepared Horde Smart Contract
Deployed HSC Address: Amhs3AYJiuVzZoG3YyiMGSMkLSb2o6earj5udcAW15JiNfia4jvJYou will get the Horde Smart Contract address.
You need to remember
- the private key of the account (ie. "6jDmfXvispppzyTcBLWa2Bgj97kU8fo5633YLdd9EAv9E235ieJ")
- and HSC address (ie. "Amhs3AYJiuVzZoG3YyiMGSMkLSb2o6earj5udcAW15JiNfia4jvJ")
If you don't modify or add any Lua code under 'sc' directory, it will not compile and will not deploy.

Deployed HSC Address: Amhs3AYJiuVzZoG3YyiMGSMkLSb2o6earj5udcAW15JiNfia4jvJAll cached data is stored in the 'hsc.deployed.payload.dat' file.
You can check the deployed HSC address again.
$ tail -n -2 hsc.deployed.payload.dat
"hsc_address": "Amhs3AYJiuVzZoG3YyiMGSMkLSb2o6earj5udcAW15JiNfia4jvJ"The Horde Smart Contract address is above, in the example it is "Amhs3AYJiuVzZoG3YyiMGSMkLSb2o6earj5udcAW15JiNfia4jvJ".
However, if you lost the private key, you could not upgrade the HSC anymore. It means you need to migrate all data every time upgrade HSC.
You can check the version the deployed HSC using HeraPy via Python.
