feat/savax-pricer Adding sAVAX pricer
Feature Name: sAvax Pricer
High Level Description
Opyn pricer to support sAVAX token on Avalanche.
sAvax is a token from the Benqi Finance team.
sAVAX uses a pool share system where the user's balance of sAVAX tokens is representative of the user's portion of the total AVAX in the whole system. The token contract keeps track of the sum of all staked AVAX and the amount of paid staking rewards, as well as the total number of minted sAVAX tokens. The ratio of these two (the exchange rate) determines the sAVAX valuation in terms of the underlying AVAX; the sAVAX tokens can always be redeemed for at least as many AVAX tokens as determined by the current exchange rate. This exchange rate changes over time, making 1 sAVAX more and more valuable as time goes on.
