This project aims for providing demos in python version for developing smart contract based on ontology. The following templates have been tested smoothly. The template contracts all work well and they can be used as reference when you write ONT smart contract.
- libs contain safe SafeMath, SafeCheck and Utils files
- migrate_destroyWithinContract.py
- MySimpleToken.py
- static_call_Oep4.py
- struct_example.py
- storage_example.py
- native_asset_invoke.py
- OEP4Sample.py
- OEP5Sample.py
- event_test.py
- Compare Executing Entry and Calling ScriptHash
- List and MapSample
- Dynamic Call Contract
For test usage, you can start ontology node and test your contract under ontology cli.
The instructions for installation of cli is given here.
The instructions for usage of cli is given here (EN, CN).
Note here that the official installation instruction is a little bit misunderstanding. Here I will give the full and correct installation guide.
2.1. Download neo-boa (ONT version)
python3 -m venv venv
cd venv/bin
activate
pip install -r requirements.txt
pip install neo-boa
2.5. You can read the docs about how to use neo-boa
Suggest you can ignore boa-test since some of the paths are configured wrongly.
Download the "python-template" zip folder and unzip it to any folder you create parallel with "boa" folder.
Open "compile_contract.py", make sure there is nothing wrong with compiling it. Then you can run this py file. Accordingly, the corresponding readable avm file will be in the corresponded folder.
Copy your avm file into your "$GOPATH/src/github.com/ontio/ontology/*" (the folder containing your ontology and wallet).
ontology --testmode --gasprice=0
Deploy smart contract in testmode. Here --code="your avm file"
./ontology contract deploy --name=xxx
--code=xxx
--author=xxx --desc=xxx --email=xxx --needstore --gaslimit=100000000
Invoke methods within your contract, please refer to the usage of ontology cli (EN, CN).
