📬Price feeder (✔️Oracle)

Docs - https://nibiru.fi/docs/run-nodes/validators/pricefeeder.html

In this example:

• a separate wallet is used (not the validator's wallet)

• a separate wallet is attached to the validator and Environment=VALIDATOR_ADDRESS='<nibivaloper1....>' is added to the service file

• a separate wallet should have coins for commissions

• the validator must be in the active set
