if [ ! $WALLET ]; then
	echo "export WALLET=wallet" >> $HOME/.bash_profile
fi
echo "export UNION_CHAIN_ID=union-testnet-6" >> $HOME/.bash_profile
source $HOME/.bash_profile

Update packages

sudo apt update && sudo apt upgrade -y

Install dependencies

sudo apt install curl build-essential git wget jq make gcc tmux net-tools ccze -y

Config app

alias uniond='uniond --home=$HOME/.union/'
uniond config chain-id $UNION_CHAIN_ID

Init app

uniond init $NODENAME --chain-id $UNION_CHAIN_ID

Download configuration

curl -Ls https://snapshot.konsortech.xyz/union/genesis.json > $HOME/.union/config/genesis.json
curl -Ls https://snapshot.konsortech.xyz/union/addrbook.json > $HOME/.union/config/addrbook.json

Set seeds and peers

sed -i -e "s|^seeds *=.*|seeds = \"[e-mail]:39165\"|" $HOME/.union/config/config.toml

Disable indexing

indexer="null"
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.union/config/config.toml

Config pruning

pruning="custom"
pruning_keep_recent="100"

sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.union/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.union/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.union/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.union/config/app.toml

Set minimum gas price

sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"0muno\"|" $HOME/.union/config/app.toml

Create service

sudo tee /etc/systemd/system/uniond.service > /dev/null <<EOF
