Download and build binaries

cd $HOME
rm -rf lava
git clone https://github.com/lavanet/lava.git
cd lava
git checkout v0.35.0

# Build binaries

export LAVA_BINARY=lavad
make build

Set up Cosmovisor and create the corresponding service

# Download and install Cosmovisor

go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest

# Prepare binaries for Cosmovisor

mkdir -p $HOME/.lava/cosmovisor/genesis/bin
mv build/lavad $HOME/.lava/cosmovisor/genesis/bin/
rm -rf build

# Create application symlinks

sudo ln -s $HOME/.lava/cosmovisor/genesis $HOME/.lava/cosmovisor/current -f
sudo ln -s $HOME/.lava/cosmovisor/current/bin/lavad /usr/local/bin/lavad -f

Initialize the node

# Set node configuration

lavad config chain-id lava-testnet-2
lavad config keyring-backend test
lavad config node tcp://localhost:14457

# Initialize the node

lavad init $LAVA_MONIKER --chain-id lava-testnet-2

# Download genesis and addrbook

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

# Add seeds

sed -i -e "s|^seeds *=.*|seeds = \"3f472746f46493309650e5a033076689996c8881@lava-testnet.rpc.kjnodes.com:14459\"|" $HOME/.lava/config/config.toml

# Set minimum gas price

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

# Set pruning

sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \

  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "19"|' \

# Set custom ports

sed -i -e "s%^proxy_app = \"tcp://\"%proxy_app = \"tcp://\"%; s%^laddr = \"tcp://\"%laddr = \"tcp://\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:14460\"%; s%^laddr = \"tcp://\"%laddr = \"tcp://\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":14466\"%" $HOME/.lava/config/config.toml

Update chain-specific configuration

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' \

Download latest chain snapshot

curl -L https://snapshots.kjnodes.com/lava-testnet/snapshot_latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.lava
[[ -f $HOME/.lava/data/upgrade-info.json ]] && cp $HOME/.lava/data/upgrade-info.json $HOME/.lava/cosmovisor/genesis/upgrade-info.json

Create service

sudo tee /etc/systemd/system/lava.service > /dev/null << EOF
Description=lava node service

[Service] User=$USER ExecStart=$(which cosmovisor) run start Restart=on-failure RestartSec=10 LimitNOFILE=65535 Environment="DAEMON_HOME=$HOME/.lava" Environment="DAEMON_NAME=lavad" Environment="UNSAFE_SKIP_BACKUP=true"

[Install] WantedBy=multi-user.target EOF

Start Service

sudo -S systemctl daemon-reload
sudo -S systemctl enable lava
sudo -S systemctl start lava
sudo systemctl status lava
sudo journalctl -u lava.service -f --no-hostname -o cat

Becoming a validator

Create wallet

lavad keys add wallet

Details such as name, address, public key, and the seed phrase are crucial and should be saved.

Faucet Lava token

Visit Lava's discord here: https://discord.com/invite/Tbk5NxTCdA

$request lava@1s4.... 

Note: lava@1s4.... is the lava wallet address you created in the step above. You need to get at least 0.2 LAVA to be able to create your validator.

Save the private validator key

cat $HOME/.lava/config/priv_validator_key.json

Please saved this file.

Check status synced

lavad status 2>&1 | jq .SyncInfo.catching_up

As soon as the value of catching_up becomes “false”.

Create a validator

lavad tx staking create-validator -y \
--chain-id lava-testnet-2 \
--moniker name_moniker \
--gas auto \
--gas-adjustment 1.5 \
--pubkey "$(lavad tendermint show-validator)" \
--amount 100000ulava \
--details "Build details..." \
--from wallet \
--commission-rate=0.1 \
--commission-max-rate=0.20 \
--commission-max-change-rate=0.01 \
--min-self-delegation 1

Ensure you replace your_moniker and details with your actual moniker.

You can check your Validator status here. Please allow some time for your validator to be added to the Lava Validator list: https://lava.explorers.guru/validators.
