UST works as an algorithmic stablecoin on the Terra blockchain. LUNA is burned to mint UST and UST is burned to mint LUNA. The synergistic relationship creates arbitrage which keeps the price of UST at or wrapped around $1.

I believe this is the same strategy you intend to apply to pHBD and pHBD-USDC. Since we now have the 20% APY interest on HBD, we have a lead if we implement the Polygon HBD.

Thanks for sharing.
