Beluga's peg stability mechanism for its pegged assets.
Anchors are a Beluga product that is designed to help maintain the peg of Beluga's asset wrappers. Through anchor pools, Beluga provides instant liquidity for redeeming Beluga's Be Assets. Anchors are built on the means of arbitrage and open a window for arbitrage to push the price of these assets to peg on secondary markets through a liquidity pool with fixed pricing.

Understanding Anchors

When understanding how anchors work, you can envision something of a vending machine. This machine takes in say, a dollar, and in return outputs a form of goods at a fixed rate. Each dollar yielding the same goods at the same quantity each and every time. This is how anchors are designed.
With anchors, a user can deposit say, 1000 beBEETS into an anchor, and in return they will get a total of 990 fBEETS from the anchor, with this rate remaining at a constant/fixed rate and fee.
With anchors, you are given the option to always be able to mint/redeem beTokens at a 1:0.99 rate, establishing a fixed price for swapping these tokens, pushing the price on secondary markets towards this rate through the means of arbitrage.

Capital Efficiency

To maintain liquidity and the peg of Beluga's assets, anchors employ capital efficiency methods to maximize the value of its reserves to ensure that each and every anchor remains liquid.
Thanks to the inherited interest-bearing properties of holding beTokens, Beluga's anchor pools are able to generate yield on its reserves to feed back into. For instance, on Beluga's beBEETS vault, holding beBEETS earns fBEETS for holders. beBEETS held in the anchor is periodically claimed by the pool and used to provide fBEETS reserves for beBEETS redemptions.
This effect amplifies the more users redeem their beTokens via anchors as the anchor's share of the vault grows and so does the yield generated by it, creating a steady flow of yield to provide consistent liquid backing for Beluga's assets.
