Manual Installation

# Download binary files
cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node
cd celestia-node/
git checkout tags/v0.23.1-mocha
make build

# Initiaton
celestia bridge init --core.ip <RPC_NODE_IP> --p2p.network mocha

Once you start the Bridge Node, a wallet key will be generated for you. You will need to fund that address with Testnet tokens to pay for PayForBlob transactions. You can find the address by running the following command:

cd $HOME/celestia-node
./cel-key list --node.type bridge --keyring-backend test --p2p.network mocha

# Create service file
sudo tee /etc/systemd/system/celestia-bridge.service > /dev/null <<EOF
