feeder

Submit exchange rate prevotes and votes, implementing the voting procedure.

Make a new key for oracle votes

You can separate the keys used for controlling a validator account from those that are submitting oracle votes on behalf of a validator. Run:

oracled keys add <feeder>

Show the feeder account details:

oracled keys show <feeder>

Delegate feeder consent

The account address used to submit oracle voting transactions is called a feeder. When you set up your oracle voting process for the first time, you must delegate the feeder permission to an account.

oracled tx oracle set-feeder <feeder-address> --from=<validator>

Instructions

  1. Install dependencies
npm install
  1. Create a key from your mnemonic

You need the mnemonic phrase for the feeder account for your validator.

npm start add-key

Enter a passphrase to encrypt your key to disk: ********
Repeat the passphrase: ********
Enter your bip39 mnemonic : <some nice mnemonic>
saved!
✨  Done in 9.19s.
