Redemption price oracle
The oracle allows you to get the latest ratio and calculate the Redemption Price by one of the formulas mentioned in the Redemption Price explanation.
Although, technically, it isn't a separate oracle contract but a method from Liquid Staking token contracts, we chose to present it as such, as logically it can be perceived as a service, and also for better discoverability.
What is Redemption Price?
The Redemption Price defines the exact amount of tokens that a user will get if he redeems its liquid staking after waiting its respective unbonding period, and it also defines the amount of Liquid Staking tokens that he receives when staking on the Ankr platform.
The formula is:
1 / ratiowhen the user redeems their Liquid Staking tokens for the assets, i.e., unstakes their assets. This is why the user gets more assets than the number of the redeemed Liquid Staking tokens.1 * ratiowhen the user stakes their assets. This is why the user gets less Liquid Staking tokens than the number of the staked assets.
All this is due to Liquid Staking tokens increasing in value overtime to the originally staked assets, which happens because ratio = TVL / (TVL + rewards).
Ankr's Redemption Price should be considered as the primary market, and market prices on Exchanges should be perceived as the second market.
