Manual configuration of the Lava node with Cosmovisor

Required packages installation

sudo apt update
sudo apt upgrade -y
sudo apt install -y curl git jq lz4 build-essential
sudo apt install -y unzip logrotate git jq sed wget curl coreutils systemd

Go installation.

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.21.7.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
eval $(echo 'export PATH=$PATH:/usr/local/go/bin' | sudo tee /etc/profile.d/golang.sh)
eval $(echo 'export PATH=$PATH:$HOME/go/bin' | tee -a $HOME/.profile)
go version

Download and build binaries

MONIKER="YOUR MONIKER"
cd $HOME
rm -rf seda-chain
git clone https://github.com/sedaprotocol/seda-chain.git
cd seda-chain
git checkout v0.0.5

Build binaries

make build

Prepare binaries for Cosmovisor

mkdir -p $HOME/.seda-chain/cosmovisor/genesis/bin
mv build/seda-chaind $HOME/.seda-chain/cosmovisor/genesis/bin/
rm -rf build

Create application symlinks

sudo ln -s $HOME/.seda-chain/cosmovisor/genesis $HOME/.seda-chain/cosmovisor/current -f
sudo ln -s $HOME/.seda-chain/cosmovisor/current/bin/seda-chaind /usr/local/bin/seda-chaind -f

Download and install Cosmovisor

go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@v1.5.0

Create service

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

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

sudo systemctl daemon-reload
sudo systemctl enable seda.service

Set node configuration

seda-chaind config chain-id seda-1-testnet
seda-chaind config keyring-backend test
seda-chaind config node tcp://localhost:17357

Initialize the node

seda-chaind init $MONIKER --chain-id seda-1-testnet

Download genesis and addrbook

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

Add seeds

sed -i -e "s|^seeds *=.*|seeds = \"3f472746f46493309650e5a033076689996c8881@seda-testnet.rpc.kjnodes.com:17359\"|" $HOME/.seda-chain/config/config.toml

Set minimum gas price

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

Set pruning

sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "19"|' \
  $HOME/.seda-chain/config/app.toml

Set custom ports

sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:17358\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:17357\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:17360\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:17356\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":17366\"%" $HOME/.seda-chain/config/config.toml

Download latest chain snapshot

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

Start service and check the logs

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

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:

seda-chaind status 2>&1 | jq .SyncInfo

Check the balance before creating for the presence of tokens

seda-chaind q bank balances $(seda-chaind keys show wallet -a)

Please enter your details below in quotation marks where required

seda-chaind tx staking create-validator \
--amount 1000000aseda \
--pubkey $(seda-chaind tendermint show-validator) \
--moniker "YOUR_MONIKER_NAME" \
--identity "FFB0AA51A2DF5955 " \
--details "i love @Dikcicrypto" \
--chain-id seda-1-testnet \
--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 0aseda \
-y

Current network:seda-1-testnet
Current version:v0.0.5

Useful commands

Check balance

seda-chaind q bank balances $(seda-chaind keys show wallet -a)

CHECK SERVICE LOGS

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

RESTART SERVICE

sudo systemctl restart seda.service

GET VALIDATOR INFO

seda-chaind status 2>&1 | jq .ValidatorInfo

DELEGATE TOKENS TO YOURSELF

seda-chaind tx staking delegate $(seda-chaind keys show wallet --bech val -a) 1000000aseda --from wallet --chain-id seda-1-testnet --gas-adjustment 1.4 --gas auto --gas-prices 0aseda -y

REMOVE NODE Please, before proceeding with the next step! All chain data will be lost! Make sure you have backed up your priv_validator_key.json!

cd $HOME
sudo systemctl stop seda.service
sudo systemctl disable seda.service
sudo rm /etc/systemd/system/seda.service
sudo systemctl daemon-reload
rm -f $(which seda-chaind)
rm -rf $HOME/.seda-chain
rm -rf $HOME/seda-chain
