Installation

If you want to setup Lava fullnode manually follow the steps below

Update and upgrade

sudo apt update && sudo apt upgrade -y

Install GO

if ! [ -x "$(command -v go)" ]; then
  ver="1.20.3"
  cd $HOME
  wget "https://golang.org/dl/go$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" >> ~/.bash_profile
  source ~/.bash_profile
fi

Install node

cd $HOME
rm -rf lava
git clone https://github.com/lavanet/lava.git
cd lava
git checkout v0.22.0
export LAVA_BINARY=lavad
make install

Setting up vars

You should replace values in <> <YOUR_MONIKER> Here you should put name of your moniker (validator) that will be visible in explorer <YOUR_WALLET> Here you shoud put the name of your wallet

LAVA_WALLET="<YOUR_WALLET_NAME>"
LAVA_NODENAME="<YOUR_MONIKER>"
LAVA_CHAIN_ID="lava-testnet-2"

echo "
export LAVA_WALLET=${LAVA_WALLET}
export LAVA_NODENAME=${LAVA_NODENAME}
export LAVA_CHAIN_ID=${LAVA_CHAIN_ID}
" >> $HOME/.bash_profile

source $HOME/.bash_profile

Configure your node

lavad config chain-id ${LAVA_CHAIN_ID}

Initialize your node

lavad init ${LAVA_NODENAME} --chain-id ${LAVA_CHAIN_ID}

Download genesis

curl -Ls "https://snapshots.l0vd.com/lava-testnet/genesis.json" > $HOME/.lava/config/genesis.json

(OPTIONAL) Set custom ports

If you want to use non-default ports

LAVA_PORT=<SET_CUSTOM_PORT> #Example: LAVA_PORT=56 (numbers from 1 to 64)

sed -i.bak -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${LAVA_PORT}658\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${LAVA_PORT}657\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${LAVA_PORT}060\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${LAVA_PORT}656\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${LAVA_PORT}660\"%" /$HOME/.lava/config/config.toml
sed -i.bak -e "s%^address = \"tcp://0.0.0.0:1317\"%address = \"tcp://0.0.0.0:${LAVA_PORT}317\"%; s%^address = \"tcp://localhost:1317\"%address = \"tcp://0.0.0.0:${LAVA_PORT}317\"%; s%^address = \":8080\"%address = \":${LAVA_PORT}080\"%; s%^address = \"0.0.0.0:9090\"%address = \"0.0.0.0:${LAVA_PORT}090\"%; s%^address = \"localhost:9090\"%address = \"localhost:${LAVA_PORT}090\"%; s%^address = \"0.0.0.0:9091\"%address = \"0.0.0.0:${LAVA_PORT}091\"%; s%^address = \"localhost:9091\"%address = \"localhost:${LAVA_PORT}091\"%; s%^address = \"0.0.0.0:8545\"%address = \"0.0.0.0:${LAVA_PORT}545\"%; s%^ws-address = \"0.0.0.0:8546\"%ws-address = \"0.0.0.0:${LAVA_PORT}546\"%" /$HOME/.lava/config/app.toml

Set seeds and peers

PEERS="[e-mail]:20656"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.lava/config/config.toml

Config pruning

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="50"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.lava/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.lava/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.lava/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.lava/config/app.toml

Set minimum gas price and null indexer

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0ulava\"/" $HOME/.lava/config/app.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.lava/config/config.toml

Set config

sed -i \
  -e 's/timeout_commit = ".*"/timeout_commit = "30s"/g' \
  -e 's/timeout_propose = ".*"/timeout_propose = "1s"/g' \
  -e 's/timeout_precommit = ".*"/timeout_precommit = "1s"/g' \

  -e 's/skip_timeout_commit = ".*"/skip_timeout_commit = false/g' \
  $HOME/.lava/config/config.toml

Create Service

sudo tee /etc/systemd/system/lavad.service > /dev/null <<EOF
[Unit]
Description=Lava testnet
After=network-online.target

[Service]
User=$USER
ExecStart=$(which lavad) start

Reset blockchain info and restart your node

sudo systemctl daemon-reload
sudo systemctl enable lavad
lavad tendermint unsafe-reset-all --home $HOME/.lava --keep-addr-book
sudo systemctl restart lavad && sudo journalctl -u lavad -f -o cat

(OPTIONAL) Use State Sync

State Sync

Starting a validator

1. Add a new key

lavad keys add ${LAVA_WALLET}

(OR)

1. Recover your key

lavad keys add ${LAVA_WALLET} --recover

LAVA_WALLET_ADDR=$(lavad keys show ${LAVA_WALLET} -a)
echo "export LAVA_WALLET_ADDR=${LAVA_WALLET_ADDR}" >> $HOME/.bash_profile

source $HOME/.bash_profile

2. Create validator

Wait until the node is synchronized.

lavad tx staking create-validator \
--amount 1000000ulava \
--commission-max-change-rate "0.01" \
--commission-max-rate "0.20" \
--commission-rate "0.1" \
