1. Description
Cronos is the Crypto.org EVM chain that aims to massively scale the DeFi ecosystem.
2. Contributing
Please abide by the Code of Conduct in all interactions and the contributing guidelines when submitting code.
3. License
4. Documentation
For detailed technical insights, check the Technical Documentation.
5. Build Full Node
To build your full node, run the following commands in your terminal:
bash
COSMOS_BUILD_OPTIONS=rocksdb make install
make build
Think of this step like setting up the foundation of a house – without a solid base, constructing the rest won’t be possible.
6. Start a Local Development Network and Node
Follow the documentation to run a local devnet.
7. Send Your First Transaction
After setting up your local devnet, you may interact with your local blockchain by following this documentation.
8. Testing
You can execute various tests in the following ways:
- Unit tests:
make test - Integration tests
CI Testing
We use Nix as our CI testing environment. First, install gomod2nix:
go install github.com/nix-community/gomod2nix@latest
gomod2nix generate
This will ensure that your tests are comprehensive and reflective of your code’s evolution over time.
9. Pystarport Quick Start
You can install Pystarport to manage nodes for development.
Install Latest Python (for Linux)
Ensure you have Python version 3.8 or above. You can install it using the following commands:
git clone git@github.com:python/cpython.git
cd cpython
git checkout tags/v3.9.5
./configure
make
sudo make install
Set Path (for Linux or for Mac)
If there are multiple Python versions, adjust your Python path as follows:
export PATH=/usr/local/bin:$HOME/.local/bin:$PATH
Install Pystarport
python3 -m pip install pystarport
Quick Start
Run two nodes in devnet:
pystarport serve --config .scripts/cronos-devnet.yaml
Get Status
pystarport supervisorctl status
Stop All
pystarport supervisorctl stop all
