BAL/ETH	0xC1438AA3823A6Ba0C159CfA8D98dF5A994bA120b

The AURA/ETH price comes from Origin's AuraWETHPriceFeed contract, which uses the Balancer 80 AURA, 20 WETH pool to get a time weighted average price (TWAP). The TWAP used is the latest AURA/WETH price with a five-minute interval. This is cross checked with the one hour interval price from five minutes earlier. If the two TWAPs are more than 2% out, the price is rejected.
