## 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](CODE_OF_CONDUCT.md) in all interactions,
and the [contributing guidelines](CONTRIBUTING.md) when submitting code.
## 3. License
[Apache 2.0](./LICENSE)
## 4. Documentation
[Technical documentation](http://cronos.org/docs).
## 5. Build full node
```bash
# COSMOS_BUILD_OPTIONS=rocksdb make install
make build
```
## 6. Start a local Development Network and Node
Please follow this [documentation](https://cronos.org/docs/getting-started/local-devnet.html#devnet-running-latest-development-node) to run a local devnet.
## 7. Send Your First Transaction
After setting the local devnet, you may interact with the your local blockchain by following this [documentation](https://cronos.org/docs/getting-started/local-devnet.html#interact-with-the-chain).
## 8. Testing
There are different tests that can be executed in the following ways:
- unit tests: `make test`
- [integration tests](./docs/integration-test.md)
### CI Testing
we use `Nix` as our CI testing environment and use `gomod2nix` to convert go modules into nix packages.
Therefore, to install `gomod2nix` is required:
```
go install github.com/nix-community/gomod2nix@latest
```
And then, you can run:
```
gomod2nix generate
```
to update `gomod2nix.toml` if any go package has changed.
## 9. Pystarport Quick Start
you can install pystarport to manage nodes for development.
### install latest python (for linux)
python version should be 3.8 or above.
you can install python like this.
```
git clone [email protected]:python/cpython.git
cd cpython
git checkout tags/v3.9.5
./configure
make
sudo make install
```
### set path (for linux or for mac)
in some cases, if there are multiple python versions, pystarport cannot be found.
then adjust python path.
also `$HOME/.local/bin` should be included to the PATH.
```
export PATH=/usr/local/bin:$HOME/.local/bin:$PATH
```
### install pystarport
```
python3 -m pip install pystarport
```
### quick start
run two nodes devnet
```
pystarport serve --config ./scripts/cronos-devnet.yaml
```
### get status
```
pystarport supervisorctl status
```
### stop all
```
pystarport supervisorctl stop all
```
