Here is a node installation guide
Preparing the server for installation
sudo apt update && sudo apt upgrade -y
sudo apt install curl tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils git make ncdu gcc git jq chrony liblz4-tool -y
Install GO
ver="1.20.5"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version
Download binaries
cd $HOME
git clone https://github.com/dymensionxyz/dymension.git
cd dymension
git checkout v2.0.0-alpha.8
make install
Init your Node
dymd init <YOUR_MONIKER> --chain-id=froopyland_100-1
dymd config chain-id froopyland_100-1
Add wallet
dymd keys add <WALLET_NAME>
Recover wallet
dymd keys add <WALLET_NAME> --recover
