Wallets

# Create wallet
saod keys add wallet

Create a password for the wallet and write it down so you don't forget it. The wallet has been created. In the last line there will be a phrase that must be written down

# If the wallet was already there, restore it
saod keys add wallet --recover
# Insert the seed phrase from your wallet
# If everything is correct, you will see your wallet data

Go to the # faucet branch and request tokens

# Save the wallet address
# Replace <your_address> with your wallet address
WALLET_SAO=<your_address>
echo "export WALLET_SAO="${WALLET_SAO}"" >> $HOME/.bash_profile
source $HOME/.bash_profile

# Check the ballance
saod q bank balances $WALLET_SAO

Validator

Do not forget to create a profile on https://keybase.io/ and set a profile photo there that will be imported by key and used for your validators.

# Change <identity> to your key from keybase
saod tx staking create-validator \
--amount 1000000sao \
--from=wallet \
--commission-rate "0.05" \
--commission-max-rate "0.20" \
--commission-max-change-rate "0.1" \
--min-self-delegation "1" \
--pubkey=$(saod tendermint show-validator) \
--moniker=$MONIKER_SAO \
--chain-id=$CHAIN_ID_SAO \
--fees=5000sao \
--identity=<identity> \
--details="" \
--website="" \
-y

Check yourself in the list explorer

Or by command

saod query staking validators --limit 1000000 -o json | jq '.validators[] | select(.description.moniker=="$MONIKER_SAO")' | jq

# Edit the validator
saod tx staking edit-validator \
  --new-moniker=$MONIKER_SAO \
