gm Pythians,
On Monday 26th, May, 2025, the FXS/USD price feed will be renamed to FRAX/USD.
While the metadata of the current FXS/USD price feed will be modified, the price feed id will remain the same as today: 0x735f591e4fed988cd38df74d8fcedecf2fe8d9111664e0fd500db9aa78b316b1
Therefore, as a user, if your protocol purely rely on the price feed id part of your integration, there is no downstream impact.
If you were to rely on a feed ticker, it is important that you prepare for such change.
As a reminder, Frax Finance has recently been changing its various tokens tickers.
-
FRAX, the stablecoin, became FRXUSD.
As a reminder, the FRAX/USD price feed is sunsetting on May 23rd, 2025 - announcement - and the FRXUSD/USD feed is already available here. -
FXS, the native token of Frax Finance, is now called FRAX, like the recently sunset stablecoin.
