Create Wallet:

evmosd keys add wallet-name

Get Wallet EVM Address

echo "0x$(evmosd debug addr $(evmosd keys show wallet-name -a) | grep hex | awk '{print $3}')"

EVM Scan:

https://scan-testnet.0g.ai

EVM Private Key and Metamask:**

evmosd keys unsafe-export-eth-key wallet-name

FAUCET:

Request for a faucet to your wallet that you created before creating validator.

https://faucet.0g.ai/

Create Validator:

Change MONIKAR_NAME with your Moniker name. Example: Rayz

evmosd tx staking create-validator
--amount=10000000000000000aevmos
--pubkey=$(evmosd tendermint show-validator)
--moniker=MONIKER_NAME
--chain-id=zgtendermint_9000-1
--commission-rate=0.05
--commission-max-rate=0.10
