```

## ***Automatic Installation***

```bash
source <(curl -s https://raw.githubusercontent.com/validexisinfra/Zetachain/main/installmain.sh)
```

## ***Manual Installation***

```bash
# Come up with the name of your node and replace it instead <your_moniker>
MONIKER=<your_moniker>
```

```bash
# Download binary files
cd $HOME
wget -O $HOME/zetacored https://github.com/zeta-chain/node/releases/download/v32.0.0/zetacored-linux-amd64
chmod +x $HOME/zetacored 
mv $HOME/zetacored $HOME/go/bin
```

```bash
# Initialize the node
zetacored config set client chain-id zetachain_7000-1
zetacored config set client keyring-backend file
zetacored init $MONIKER --chain-id=zetachain_7000-1
```

<pre class="language-bash"><code class="lang-bash"># Download genesis and addrbook

</strong>curl -L https://snapshots.nodejumper.io/zetachain/addrbook.json > $HOME/.zetacored/config/addrbook.json
</code></pre>

***Setup config***

```bash
# Set seeds and peers
sed -i -e 's|^seeds *=.*|seeds = "20e1000e88125698264454a884812746c2eb4807@seeds.lavenderfive.com:22556,1d41d344d3370d2ba54332de4967baa5cbd70a06@rpc.zetachain.nodestake.org:666,ade4d8bc8cbe014af6ebdf3cb7b1e9ad36f412c0@seeds.polkachu.com:22556,8d93468c6022fb3b263963bdea46b0a131d247cd@34.28.196.79:26656,637077d431f618181597706810a65c826524fd74@zetachain.rpc.nodeshub.online:22556,11b86546b092e0645a91b32ca78e40c8bec54546@zetachain-m.peer.stavr.tech:17656"|' $HOME/.zetacored/config/config.toml

# Config pruning

sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"19\"/" $HOME/.zetacored/config/app.toml

```

#### ***Set custom ports***

You can change value CUSTOM\_PORT=161 To any other ports

```bash
CUSTOM_PORT=161
```

```bash
sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${CUSTOM_PORT}58\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${CUSTOM_PORT}57\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${CUSTOM_PORT}60\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${CUSTOM_PORT}56\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${CUSTOM_PORT}66\"%" $HOME/.zetacored/config/config.toml
sed -i -e "s%^address = \"tcp://localhost:1317\"%address = \"tcp://localhost:${CUSTOM_PORT}17\"%; s%^address = \":8080\"%address = \":${CUSTOM_PORT}80\"%; s%^address = \"localhost:9090\"%address = \"localhost:${CUSTOM_PORT}90\"%; s%^address = \"localhost:9091\"%address = \"localhost:${CUSTOM_PORT}91\"%; s%^address = \"0.0.0.0:8545\"%address = \"0.0.0.0:${CUSTOM_PORT}45\"%; s%^ws-address = \"0.0.0.0:8546\"%ws-address = \"0.0.0.0:${CUSTOM_PORT}46\"%" $HOME/.zetacored/config/app.toml
```

```bash
#Set config with new custom port
zetacored config set client node tcp://localhost:${CUSTOM_PORT}57
```

```bash
# Create service file
sudo tee /etc/systemd/system/zetacored.service > /dev/null <<EOF

```bash
# Download latest chain snapshot
curl "https://snapshots.nodejumper.io/zetachain/zetachain_latest.tar.lz4" | lz4 -dc - | tar -xf - -C "$HOME/.zetacored"
```

```bash
# Enable and start service
sudo systemctl daemon-reload
sudo systemctl enable zetacored
sudo systemctl restart zetacored && sudo journalctl -u zetacored -fo cat
```

```bash
# Check status
zetacored status 2>&1 | jq .SyncInfo

#"catching_up": false means that the node is synchronized, we are waiting for complete synchronization
```

***Wallets***

```bash
# Create wallet
zetacored keys add wallet
```

The wallet has been created. In the last line there will be a phrase that must be written down

```bash
# If the wallet was already there, restore it
zetacored keys add wallet --recover

# Insert the seed phrase from your wallet
# If everything is correct, you will see your wallet data
```

***Validator***

Do not forget to create a profile on <https://keybase.io/> and set a profile photo there that will be imported by key and used for your validators.

```bash
# Change <identity> to your key from keybase
zetacored tx staking create-validator \
--amount 1000000azeta \
--from=wallet \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--pubkey $(zetacored tendermint show-validator) \
--moniker=$MONIKER \
--identity=<identity> \
--website "" \
--details "" \
--chain-id zetachain_7000-1 \
--gas-prices=20000000000azeta \
--gas-adjustment=1.5 \
--gas=auto \
-y 
```

**!!! Save priv\_validator\_key.json which is located in /root/.zetacored/config**
