Enable and start service
sudo systemctl daemon-reload
sudo systemctl enable evmosd
sudo systemctl start evmosd
sudo journalctl -u evmosd -f -o cat
After successful synchronisation we recommend to turn off snapshot_interval and state sync, this will save space on your hardware.

Wallet creation
Create wallet
⚠️ store seed phrase, important during recovering
evmosd keys add <YOUR_WALLET_NAME>
Recover wallet

Validator creation
After successful synchronisation we can proceed with validation creation.
Create validator
evmosd tx staking create-validator \
