Set up a pricefeeder

info

{% hint style="warning" %}

To run pricefeeder you validator should be in active set. Otherwise price feeder will not vote on periods. {% endhint %}

  1. Install the pricefeeder binary
curl -s https://get.nibiru.fi/pricefeeder! | bash
  1. Create new wallet for pricefeeder and save 24 word mnemonic phrase
nibid keys add pricefeeder-wallet
  1. Top up the pricefeeder-wallet going to Nibiru Discord #faucet channel. {% hint style="info" %} In order to make pricefeeder work, it needs some testnet tokens to pay for transaction fees {% endhint %}

  2. Export pricefeeder mnemonic into environment variable

export FEEDER_MNEMONIC="my pricefeeder 24 word mnemonic phrase goes here ..."
  1. Setup the systemd service
export CHAIN_ID="nibiru-itn-1"
export GRPC_ENDPOINT="localhost:39090"
export WEBSOCKET_ENDPOINT="ws://localhost:39657/websocket"
export EXCHANGE_SYMBOLS_MAP='{ "bitfinex": { "ubtc:uusd": "tBTCUSD", "ueth:uusd": "tETHUSD", "uusdt:uusd": "tUSTUSD" }, "binance": { "ubtc:uusd": "BTCUSD", "ueth:uusd": "ETHUSD", "uusdt:uusd": "USDTUSD", "uusdc:uusd": "USDCUSD", "uatom:uusd": "ATOMUSD", "ubnb:uusd": "BNBUSD", "uavax:uusd": "AVAXUSD", "usol:uusd": "SOLUSD", "uada:uusd": "ADAUSD", "ubtc:unusd": "BTCUSD", "ueth:unusd": "ETHUSD", "uusdt:unusd": "USDTUSD", "uusdc:unusd": "USDCUSD", "uatom:unusd": "ATOMUSD", "ubnb:unusd": "BNBUSD", "uavax:unusd": "AVAXUSD", "usol:unusd": "SOLUSD", "uada:unusd": "ADAUSD" } }'

  1. Delegate pricefeeder responsibility

{% hint style="info" %} As a validator, if you'd like another account to post prices on your behalf (i.e. you don't want your validator mnemonic sending txs), you can delegate pricefeeder responsibilities to another nibi address. {% endhint %}

nibid tx oracle set-feeder $(nibid keys show pricefeeder-wallet -a) --from wallet
  1. Register and start the systemd service
sudo systemctl daemon-reload && \
sudo systemctl enable pricefeeder && \
sudo systemctl start pricefeeder
  1. View pricefeeder logs
journalctl -fu pricefeeder
