Localnet Setup Guide

This guide provides instructions on how to spin up a new localnet using the Elys network for development purposes. Follow these steps to set up your localnet environment.

Prerequisites

Getting Started

  1. Clone the Elys Repository

    First, clone the Elys repository to your local machine:

    git clone https://github.com/elys-network/elys.git
  2. Build the Binary

    Navigate into the cloned repository and build the binary using:

    git tag -f v999.999.999 && make install

    This command will install the elysd daemon.

  3. Download the Latest TestNet Snapshot

    To get the latest TestNet snapshot available for the Elys network, use the following command to download the latest TestNet snapshot that uses the changes from the main branch:

    rm -rf ~/.elys && curl -o - -L https://snapshots.elys.network/elys-snapshot-main.tar.lz4 | lz4 -c -d - | tar -x -C ~/
  4. Spin Up the Localnet

    Use the command below to start the localnet:

    elysd start

Installation

With Makefile (Recommended)

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.

Click to expand/collapse 1. Clone the Elys chain repository: ```bash git clone https://github.com/elys-network/elys.git ``` 2. Navigate to the cloned repository: ```bash cd elys ``` 3. Optionally, checkout the specific branch or tag you want to build: ```bash git checkout ``` 4. Ensure that you have the necessary dependencies installed. For instance, on Ubuntu you need to install the `make` tool: ```bash sudo apt-get install --yes make ``` 5. **Optional**: Use _RocksDB_ instead of _pebbledb_ Ensure that you have RocksDB installed on your machine. On Ubuntu, you can install RocksDB using the following suite of commands: ```bash # set rocks db version ROCKSDB_VERSION=8.9.1 # install rocks db dependencies sudo apt install -y libgflags-dev libsnappy-dev zlib1g-dev libbz2-dev liblz4-dev libzstd-dev # download and extract on /tmp cd /tmp wget https://github.com/facebook/rocksdb/archive/refs/tags/v${ROCKSDB_VERSION}.tar.gz tar -xvf v${ROCKSDB_VERSION}.tar.gz && cd rocksdb-${ROCKSDB_VERSION} || return # build rocks db export CXXFLAGS='-Wno-error=deprecated-copy -Wno-error=pessimizing-move -Wno-error=class-memaccess' make shared_lib # install rocks db sudo make install-shared INSTALL_PATH=/usr # cleanup to save space rm -rf /tmp/rocksdb-${ROCKSDB_VERSION} /tmp/v${ROCKSDB_VERSION}.tar.gz ``` In order to build the binary with RocksDB, you need to run the following command: ```bash ROCKSDB=1 make build ``` Note: RocksDB is only required for Linux machines. For macOS, you can continue without installing RocksDB. When running `ROCKSDB=1 make build`, if you are getting this error: ```bash elysd: error while loading shared libraries: librocksdb.so.8.9: cannot open shared object file: No such file or directory ``` You might need to set the `LD_LIBRARY_PATH` environment variable to the local library path. You can do this by running the following command: ```bash export LD_LIBRARY_PATH=/usr/local/lib ``` 6. Run the `make build` command to build the binary: ```bash make build ``` 7. The binary will be generated in the `./build` directory. You can run the binary using the following command: ```bash ./build/elysd ``` You can also use the `make install` command to install the binary in the `bin` directory of your `GOPATH`.

With Ignite (Experimental)

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

Development

You can use ignite-cli to get you started with your development environment. To install ignite-cli, execute the following command on your machine:

curl https://get.ignite.com/ignite/ignite-cli@latest! | sudo bash

Initialize

To initialize and serve your development environment, execute the following command:

ignite chain serve -r

serve command installs dependencies, builds, initializes, and starts Elys in development. The -r flag rebuilds the binary before starting the chain.

Release

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.
