Setup your node on Lava

Introduction

Lava uses a cryptoeconomic incentive framework and appchain to coordinate node runners and applications in the trustless exchange of blockchain RPC service. Web3 must diversify its node operators to ensure that the ecosystem can achieve censorship-resistance; Lava creates this diversity. The Network also includes several novel innovations across its technology stack and blockchain, including mechanisms for ensuring data integrity, scalability and privacy.

wget -O lava.sh https://raw.githubusercontent.com/appieasahbie/lava/main/lava.sh && chmod +x lava.sh && ./lava.sh

post installation

source $HOME/.bash_profile

(Check the status of your node)

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

open ports and active the firewall

  sudo ufw default allow outgoing
  sudo ufw default deny incoming
  sudo ufw allow ssh/tcp
  sudo ufw limit ssh/tcp
  sudo ufw allow ${LAVA_PORT}656,${LAVA_PORT}660/tcp
  sudo ufw enable

Create wallet

• (Please save all keys on your notepad)

  lavad keys add $WALLET
  

• To recover your old wallet use this command

  lavad keys add $WALLET --recover
  

• show keys

  lavad keys list
  

Fund your wallet (to create validator) Discord channel #faucet

Create validator (after recieving of tokens and must important sync is false)

• replace with your wallet name and with your validator name

   lavad tx staking create-validator \
    --amount=90000ulava \
    --pubkey=$(lavad tendermint show-validator) \
    --moniker="Yourvalidatorname" \
    --chain-id=lava-testnet-1 \
    --commission-rate=0.1 \
    --commission-max-rate=0.2 \
    --commission-max-change-rate=0.05 \
    --min-self-delegation=1 \
    --fees=10000ulava \
    --from=Yourwalletname \
    -y
  

Snapchot (optional)

  sudo systemctl stop lavad

  cp $HOME/.lava/data/priv_validator_state.json $HOME/.lava/priv_validator_state.json.backup 

  lavad tendermint unsafe-reset-all --home $HOME/.lava --keep-addr-book 
  curl https://snapshot.lava.aknodes.net/snapshot-lava.AKNodes.lz4 | lz4 -dc - | tar -xf - -C $HOME/.lava

  mv $HOME/.lava/priv_validator_state.json.backup $HOME/.lava/data/priv_validator_state.json 

  sudo systemctl start lavad
  sudo journalctl -u lavad -f --no-hostname -o cat

Cheat Sheet

Delegate to yourself

  lavad tx staking delegate $(lavad keys show wallet --bech val -a) 1000000ulava --from wallet --chain-id lava-testnet-1 --gas-prices 0.1ulava --gas-adjustment 1.5 --gas auto -y 

Redelegate

  lavad tx staking redelegate $(lavad keys show wallet --bech val -a) 1000000ulava --from wallet --chain-id lava-testnet-1 --gas-prices 0.1ulava --gas-adjustment 1.5 --gas auto -y  

Get Validator Info

 lavad status 2>&1 | jq .ValidatorInfo

Get Catching Up

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

Get Latest Height

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

Get Peer

 echo $(lavad tendermint show-node-id)'@'$(curl -s ifconfig.me)':'$(cat $HOME/.lavad/config/config.toml | sed -n '/Address to listen for incoming connection/{n;p;}' | sed 's/.*://; s/".*//')

Reset Node

lavad tendermint unsafe-reset-all --home $HOME/.lavad --keep-addr-book

    --identity=XXXXXXXXXXXX \
    --details="xxxxxxxxxx" \
    --chain-id=lava-testnet-1 \
    --from=wallet \
    --fees=5000ulava \
    -y
