[[ -f $HOME/.lava/data/upgrade-info.json ]] && cp $HOME/.lava/data/upgrade-info.json $HOME/.lava/cosmovisor/genesis/upgrade-info.json

Start service and check the logs

sudo systemctl start lava.service && sudo journalctl -u lava.service -f --no-hostname -o cat

Becoming a Validator

Create wallet key new

lavad keys add wallet

(OPTIONAL) RECOVER EXISTING KEY

lavad keys add wallet --recover

We receive tokens from the tap in the discord

then go to the #faucet branch and write $request your lava address(lava@....)

Create the Validator

Before creating a validator, enter the command and check that you have false. This means that the Node has synchronized and you can create a validator:

lavad status 2>&1 | jq .SyncInfo

Check the balance before creating for the presence of tokens

lavad q bank balances $(lavad keys show wallet -a)

Please enter your details below in quotation marks where required

lavad tx staking create-validator \
--amount 1000000ulava \
--pubkey $(lavad tendermint show-validator) \
--moniker "YOUR_MONIKER_NAME" \
--identity "FFB0AA51A2DF5955 " \
--details "i love YTWO" \
--chain-id lava-testnet-2 \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--gas-prices 0ulava \
-y

Update

cd && rm -rf lava
git clone https://github.com/lavanet/lava
cd lava
git checkout v2.0.0
make install-all

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

Current network:lava-testnet-2
Current version:v2.0.0

Useful commands

Check balance

lavad q bank balances $(lavad keys show wallet -a)

CHECK SERVICE LOGS

sudo journalctl -u lava.service -f --no-hostname -o cat

RESTART SERVICE

sudo systemctl restart lava.service

GET VALIDATOR INFO

lavad status 2>&1 | jq .ValidatorInfo

DELEGATE TOKENS TO YOURSELF

lavad tx staking delegate $(lavad keys show wallet --bech val -a) 1000000ulava --from wallet --chain-id lava-testnet-2 --gas-adjustment 1.4 --gas auto --gas-prices 0ulava -y
