- swETH/ ETH based on swETH/USD and ETH/USD (see additional notes below).
|Oracle on Ethereum network
|Is testnet deploy required?
Additional relevant information:
We will provide an adapter contract for you to get the latest price of swETH/ETH.
The adapter contract will retrieve the latest updates from two feeds: swETH/USD and ETH/USD.
As all our feeds are denominated in USD, we can provide two main advantages:
The price feed will always be extensible for new pools, DEXes and pairs (even pairs not including ETH, e.g., a future swETH/USDC pair)
The price feed will “anticipate” market price changes even when no trades happen in any swETH/ETH pool, e.g., due to a high gas environment in a turbulent market situation. By keeping the latest ETH price updated, the generated price should be closer to the fair market value compared to just taking the potentially stale last actual trade price of swETH/ETH without correcting the value of ETH itself that occurred in the meantime.
Any recorded trade of swETH/ETH is denominated in USD by multiplying it with the current ETH/USD price in our system which depends on CEX and DEX data and is highly reliable. This measure should increase price stability, fair market price evaluation, and will decrease deployment times and the effort for changes and maintenance for your feed.
Additional markets/ pools shall be added when TVL approx. >2mn.
Additional pools may benefit from a longer trade aggregation window size. Additions/ changes in methodology and parameters will be noted in the CDR.
