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.

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

Wallet creation

Create wallet

⚠️ store seed phrase, important during recovering

evmosd keys add <YOUR_WALLET_NAME>

Recover wallet

⚠️ store seed phrase, important during recovering

evmosd keys add <YOUR_WALLET_NAME> --recover

Validator creation

After successful synchronisation we can proceed with validation creation.

Create validator

evmosd tx staking create-validator \
--amount=1000000000000000000atevmos \
--pubkey=$(evmosd tendermint show-validator) \
--moniker="<Your moniker>" \
