There are different types of keys, validator and wallet keys. do have a look at the link above @Superbit123 @Bernando @KuzoIV .
Additionally, once youve bounded your wallet to the validator key in the create-validator transaction, majority of subsequent queries/transactions made be made in a validator’s capacity.
for eg. say you would like to vote on a proposal
fxcored tx gov vote <proposal_id> <Yes/No/NoWithVeto/Abstain>
–from=<_name>
–chain-id=<chain_id>
running the above command, and inputting your wallet key say --from=Richard (this key will be pointing to my wallet’s address with the prefix fx…)
Additionally do not forget to add the gas fields to your above transaction
–gas=“auto”
–gas-adjustment=1.2
–gas-prices=“4000000000000FX”
because your validator key is bounded to the wallet address, sending the transaction above will vote on behalf of all your delegated stake as well.
