To create a validator at symphony, you should import the data of your validator to the validator.json file
nano $HOME/.symphonyd/validator.json
After opening the validator file, you can paste all of these inside identity
{
"pubkey": {"@type":"/cosmos.crypto.ed25519.PubKey.......},
"amount": "5000000note",
"moniker": "",
"identity": "",
"website": "",
"security": "",
"details": "",
"commission-rate": "0.05",
"commission-max-rate": "0.2",
"commission-max-change-rate": "0.01",
"min-self-delegation": "1"
}
Fill the pubkey using the result of this command
symphonyd tendermint show-validator
