Enable and start service

sudo systemctl daemon-reload
sudo systemctl enable crossfid
sudo systemctl start crossfid

sudo journalctl -u crossfid -f -o cat

After successful synchronisation we recommend to turn off snapshot_interval and state sync, this will save space on your hardware.

snapshot_interval=0
sed -i.bak -e "s/^snapshot-interval *=.*/snapshot-interval = \"$snapshot_interval\"/" ~/.crossfid/config/app.toml
sed -i 's|^enable *=.*|enable = false|' $HOME/.crossfid/config/config.toml
sudo systemctl restart crossfid && sudo journalctl -u crossfid -f -o cat

Wallet creation

Create wallet

⚠️ store seed phrase, important during recovering

crossfid keys add <YOUR_WALLET_NAME>

Recover wallet

⚠️ store seed phrase, important during recovering

crossfid keys add <YOUR_WALLET_NAME> --recover

Validator creation

After successful synchronisation we can proceed with validation creation.

Create validator

crossfid tx staking create-validator \
