Price Oracle

Implementation of a Price Oracle that fetches price data from Coingecko and Binance. This is heavily influenced from Kava Labs' implementation https://github.com/Kava-Labs/kava-tools/blob/master/oracle/

Setup (Local)

All steps should be run in this directory (sei-chain/oracle/)

Install the oracle software

yarn

Configure a .env file. Example:

# Cron tab for how frequently prices will be posted (ex: 5 minutes)
CRONTAB="*/5 * * * *"

# List of markets the oracle will post prices for. See pricefeed parameters for the list of active markets.
MARKET_IDS="bnb:usd,bnb:usd:30,btc:usd,btc:usd:30,xrp:usd,xrp:usd:30,busd:usd,busd:usd:30,kava:usd,kava:usd:30,hard:usd,hard:usd:30,usdx:usd"

Run the oracle process:

node main.js

Setup (Launch ec2 instance)

All the local steps aboved are bundled in an Ansible playbook that will launch, configure and start an Oracle for you in AWS. Simply run:

GIT_USER=$GIT_USER GIT_ACCESS_TOKEN=$GIT_ACCESS_TOKEN ansible-playbook oracle/deploy.yaml
