Prop 389: Upload Stride Redemption Rate Oracle Contract

Passing this proposal will upload the Stride Redemption Rate Oracle Contract to the Injective chain

## Summary

The Stride Redemption Rate Oracle Contract uses an interchain account (ICA) to provide the redemption rates of Stride’s stTokens to the Injective blockchain in a decentralized manner.

If uploaded to Injective, the Oracle Contract’s feeds could be integrated with Levana’s and Neptune's oracle implementation to provide a more dependable oracle price for stTokens.

## Details

The way Stride’s liquid staking works is - stTokens represent underlying staked tokens, which are controlled by the Stride blockchain. At any time, a user may use his stToken to redeem a certain amount of its underlying token. The amount of underlying tokens a single stToken can redeem is called the redemption rate. For example, on the Stride blockchain 1 stINJ can currently be used to redeem 1.1098 INJ. So 1.1098 is the current redemption rate for stINJ. To continue with the example, the market price of stINJ vs INJ may fluctuate - but the true value of stINJ vs INJ is defined by the redemption rate.

The Oracle Contract uses an ICA to provide redemption rates for Stride’s stTokens to the Injective blockchain in a decentralized manner. As mentioned above, stToken redemption rates on Injective can be used to trustlessly manage the scaling factors for stToken stableswap pools and to strengthen stToken price oracles on Injective.
