Volatile prices can cause issue when users try to do rigidRedemption.
Volatile prices can cause slippage loss when users use rigidRedemption(). This function takes PeUSD (stable coin) amount and converts it to WstETH/stETH (variable price). Unfortunately, rigidRedemption() does not include timestamp or minAmount received, meaning this trade can be executed later in time and at a different price than user previously expected.
