ignite chain serve
serve command installs dependencies, builds, initializes, and starts Elys in development.
To install the latest version of Elys binary, execute the following command on your machine:
curl https://get.ignite.com/elys-network/elys@latest! | sudo bash
This section provides a step-by-step guide on how to build the Elys Chain binary from the source code using the provided makefile. The makefile automates the build process and generates a binary executable that can be run on your local machine.

- Clone the Elys chain repository:
git clone https://github.com/elys-network/elys.git- Navigate to the cloned repository:
cd elys- Optionally, checkout the specific branch or tag you want to build:
git checkout <version>note: 'latest' is currently not recognized but will be supported in the next version (eg use 'git checkout v.0.2.3')
- Ensure that you have the necessary dependencies installed. For instance, on Ubuntu you need to install the
maketool:
sudo apt-get install --yes make- Run the
make buildcommand to build the binary:
make build- The binary will be generated in the
./builddirectory. You can run the binary using the following command:
./build/elysdYou can also use the make install command to install the binary in the bin directory of your GOPATH.
The validator guide is accessible here.
This section provides a step-by-step guide on how to launch a new network, such as a testnet, for Elys. The guide includes instructions on how to use Ignite commands to set up and configure the new network.

To publish the information about Elys chain as a coordinator, run the following command:
ignite network chain publish github.com/elys-network/elys --tag v0.1.0 --chain-id elystestnet-1 --account-balance 10000000000uelys
This documentation presupposes the validator node is currently operational on Ubuntu 22.04.2 LTS.
Before launching a validator node, a set of tools must be installed.
To install the build-essential package, enter the following command:
sudo apt install build-essential
Install go version 1.19
cd /tmp
wget https://go.dev/dl/go1.19.7.linux-amd64.tar.gz
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf go1.19.7.linux-amd64.tar.gz
Append the following line to the end of the ~/.bashrc file:
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
Run the following command:
go version
This should return the following output:
go version go1.19.7 linux/amd64
Install ignite-cli
Enter the following command to install the ignite-cli command:
curl https://get.ignite.com/cli! | bash
Then run the following command:
ignite network
Install the latest version of Elys binary by running the following command:
curl https://get.ignite.com/elys-network/elys@latest! | sudo bash
Enter the following command to initialize the validator node and request to join the network:
ignite network chain init 12
ignite network chain join 12 --amount 95000000uelys
The coordinator will then have to approve the validator requests with the following commands:
ignite network request list 12
ignite network request approve 12 <REQUEST_ID>,<REQUEST_ID>
Once all the validators needed for the validator set are approved, to launch the chain use the following command:
ignite network chain launch 12
Each validator is now ready to prepare their nodes for launch by using this command:
ignite network chain prepare 12
The output of this command will show a command that a validator would use to launch their node such as:
elysd start --home $HOME/spn/12 2> elysd.log &
A systemd service can be created to auto-start the elysd service.
Create the new file /etc/systemd/system/elysd.service with this content:
[Unit]
Description=Elysd Service
Wants=network.target
After=network.target
[Service]
Environment=HOME=/home/ubuntu
Type=simple
Restart=on-failure
WorkingDirectory=/home/ubuntu
SyslogIdentifier=elysd.user-daemon
ExecStart=/home/ubuntu/go/bin/elysd start --home spn/12 2>&1
ExecStop=/usr/bin/pkill elysd
[Install]
WantedBy=multi-user.target
Then you can use those commands to enable and start the service:
sudo systemctl enable elysd.service
sudo systemctl start elysd.service
You can check the status of the service at any time using this command:
sudo systemctl status elysd.service
Or follow the service logs by using this command:
sudo journalctl -u elysd.service -f

The boilerplate was generated using ignite CLI, which provides a convenient way to generate new chains, modules, messages, and more. The initial modules that are part of the repository include AssetProfile and LiquidityProvider, both of which were generated using the ignite CLI.
AssetProfile requires all changes to go through governance proposals (i.e., adding, updating, or deleting an asset profile entry). Similarly, any modules that expose parameters must require governance proposals to update the module parameters.
The repository also includes a config.yml file, which provides a convenient way to initiate the genesis account, set up a faucet for testnet, define initial validators, and override initial genesis states. Although ignite provides the network layer that allows for easy onboarding of new validators to a chain network, the config.yml file can be used to specify additional configurations.
In the current config.yml file, additional denom metadata has been defined to allow for easy setting of the ELYS amount using any exponent (decimal precision) following the EVMOS good practices. The governance params have also been overridden to reduce the voting period to 20 seconds for local test purposes. Multiple config.yml files can be created for each environment (local, testnet, mainnet) with their specific parameters.
A proposal can be submitted to add one or multiple entries in the asset profile module. The proposal must be in the following format:

To release a new version of Elys, create and push a new tag with v prefix. A new draft release with the configured targets will be created.
git tag v0.1
git push origin v0.1
After a draft release is created, make your final changes from the release page and publish it.
