Official documentation

Before We begin for your easier understanding

CONSENSUS_NODE is same as celestia-app node

Core ip can be consensus node ip or an RPC endpoint

Setting Variables

RPC_NODE_IP="Your-RPC-ENDPOINT"
RPC_PORT="Your-RPC-PORT"

Download and build binary

# Clone project repository
cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node
git checkout v0.20.4
make build
make install
make cel-key

#if you face permission error
sudo chown -R $USER:$USER /usr/local/bin/
sudo chmod -R 755 /usr/local/bin/

Your celestia Bridge Node is saved at /usr/local/bin/celestia

Initializing Bridge Node

# After starting the Bridge Node, a wallet key will be generated for you. 
celestia bridge init --core.ip RPC_NODE_IP

To facilitate Blob transactions, you must fund this address with Mainnet tokens.

If you did not save the wallet address you can find the address by running the following command:

cd $HOME/celestia-node 
./cel-key list --node.type bridge --keyring-backend test

Creating Systemd

Without Metrics - if you do not want your metrics to be reported

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

[Service]
User=$USER
ExecStart=/usr/local/bin/celestia bridge start --core.ip $RPC_NODE_IP --core.rpc.port $RPC_PORT 
Restart=on-failure
RestartSec=3
LimitNOFILE=1400000

[Install]
WantedBy=multi-user.target
EOF

With Metrics

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

[Service]
User=$USER
ExecStart=/usr/local/bin/celestia bridge start --core.ip $RPC_NODE_IP --core.rpc.port $RPC_PORT --metrics.tls=true --metrics --metrics.endpoint otel.celestia.observer

Enable and start the service

sudo systemctl daemon-reload
sudo systemctl enable celestia-bridge.service
sudo systemctl restart celestia-bridge && sudo journalctl -u celestia-bridge -f -o cat

Retrieve your node's peerId information.

Note: You can only generate an auth token after initializing and starting your Celestia node.

NODE_TYPE=bridge
AUTH_TOKEN=$(celestia $NODE_TYPE auth admin)

curl -X POST \
     -H "Authorization: Bearer $AUTH_TOKEN" \
     -H 'Content-Type: application/json' \
     -d '{"jsonrpc":"2.0","id":0,"method":"p2p.Info","params":[]}' \
