Creat a Validator Wallet

mttd keys add alice --home HOMEDIR --keyring-backend file

It will print a message similar to the following (⚠️: Please do not use the following address, as the private key is exposed).

Re-enter keyring passphrase:

- address: mtt1wquq2cfc7dcjyg429ytc5gveckfd7lc9e0jfqg
  name: alice
  pubkey: '{"@type":"/ethermint.crypto.v1.ethsecp256k1.PubKey","key":"AlW+clWNea0SLQhaqoqC230VmM92jbkM5y3ajDR8Gbip"}'
  type: local


**Important** write this mnemonic phrase in a safe place.
It is the only way to recover your account if you ever forget your password.

Obtain wallet address

Run the following command to obtain the EVM address, and replace it with your own address starting with "mtt".

mttd debug addr mtt1wquq2cfc7dcjyg429ytc5gveckfd7lc9e0jfqg

Print like this:

Address bytes: [112 56 - 97 56 - 113 - 34 - 41 23 138 - 153 197 146 223 127 5]

Creat a Validator

You can view the pubkey using :

mttd tendermint show-validator --home HOMEDIR

Print like this:

{"@type":"/cosmos.crypto.ed25519.PubKey","key":"0loT2LrdSncdg2PoWd+te5keYoM08Dy/q7rH/6RUgc8="}

Staking operation

The current command stakes 1 million MTT by default. You can modify the amount, with a minimum of 10,000 . Note that 1 MTT = 1e18 aMTT, so the staking amount includes 18 additional zeros.

MONIKER , WEBSITE and DETAIL are the parameters that can be modified according to your needs.

commission-rate, commission-max-rate and commission -max-change-rate are the parameters related to charging the commission fee to the delegators.

mttd tx staking create-validator --amount 1000000000000000000000000amtt --pubkey '{"@type":"/cosmos.crypto.ed25519.PubKey","key":"0loT2LrdSncdg2PoWd+te5keYoM08Dy/q7rH/6RUgc8="}' --moniker MONIKER --website WEBSITE --details DETAIL --from alice --fees 20000000000000000amtt --commission-rate="0.05" --commission-max-rate="0.20" --commission-max-change-rate="0.01" --min-self-delegation="1000000000000000000000" --gas auto --gas-adjustment 1.2 --home HOMEDIR --keyring-backend file

Then, check if the operation was successful.

mttd q staking validator mttvaloper1wquq2cfc7dcjyg429ytc5gveckfd7lc9xml4r4

mttvaloper1wquq2cfc7dcjyg429ytc5gveckfd7lc9xml4r4 is the "Bech32 Val:" part output from the wallet address. If detailed information is found, it indicates that the node creation was successful.
