📝 Create Validator

1️⃣ Create wallet

sedad keys add wallet

Save all information after entering the command, without this you will not be able to restore data to the wallet. SAVE SEED PHRASE (12 words).

2️⃣ Buy tokens to start a node on one of the CEX / DEX exchanges

https://www.mexc.com/ https://www.digifinex.com/

After that, copy your newly created wallet from the terminal and send the purchased tokens to the SEDA network

3️⃣ View your wallet balance

sedad keys q bank balances "address"

if the balance is displayed - continue further

4️⃣ View the sync status of your node

sedad status | jq | grep "catching_up"

If "true" - not synchronized // "false" - synchronized

5️⃣ Create validator

sedad tx staking create-validator \
--amount=1000000aseda \
--pubkey=$(sedad tendermint show-validator) \
--moniker "Alex" \ #Validator name, displayed in explorers.
--identity "" \ #Use your KeyBase ID. If you don't have one, leave it empty.
--website "mywebsite.com" \ #Your website is available, or leave the field blank
--details "A reliable validator of your network" \ #Any details about your validator.
--chain-id=seda-1 \
--commission-rate=0.10 \
--commission-max-rate=0.20 \
--commission-max-change-rate=0.01 \
--min-self-delegation=1 \
--from=wallet \ #or your wallet name
--gas-prices=10000000000aseda \
--gas-adjustment=1.5 \
--gas=auto \
-y 

After entering the command, you will receive hash transactions, check the status in the explorer

6️⃣ Save priv_validator_key.json

cat $HOME/.sedad/config/priv_validator_key.json

SAVE YOUR PRIVATE KEY AFTER ENTERING THE COMMAND
