OETH / ETH Price Feed (Chainlink Oracle)
wOETH LayerZero Adapter
The following Chainlink oracles are used to protect the vault in case a backing asset loses value. They also offer slippage protection when harvesting rewards tokens.
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.
