Node Start

celestia-appd tendermint unsafe-reset-all --home $HOME/.celestia-app
sudo systemctl enable celestia-appd
sudo systemctl start celestia-appd

Check If Daemon Has Been Started Correctly

sudo systemctl status celestia-appd
  • You can exit the status screen by pressing ctrl+c

Check Daemon Logs in Real Time

sudo journalctl -u celestia-appd.service -f

To check If Your Node is in Sync Before Going Forward

curl -s localhost:26657/status | jq .result | jq .sync_info

latest_block_height = compare its value with the explorer value. When they are identical to each other, synchronization to the system is complete.

Wallet

celestia-appd keys add walletname

celestia-appd keys add walletname --recover
  • Do not forget to save your wallet information (words)!
  • To get a test token, you must enter the Faucet section and type as follows. https://discord.gg/JeRdw5veKu
