/cronos

Cronos is the first Ethereum-compatible blockchain network built on Cosmos SDK technology. Cronos aims to massively scale the DeFi, GameFi, and overall Web3 user community by providing builders with the ability to instantly port apps and crypto assets from other chains while benefiting from low transaction fees, high throughput, and fast finality.

Please follow this documentation to run a local devnet.

After setting the local devnet, you may interact with the your local blockchain by following this documentation.

There are different tests that can be executed in the following ways:

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.

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 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)

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
