I have one question about bonded stablecoins. Is any way to redeem both t1 & t2 (e.g. IUSD & GRD) in one TX to minimise curve fee and t2 price impact?
I think so, but there is no UI for that yet, it needs to be done programmatically with headless-obyte or obyte.js library. For example, chatbot can generate payment request for multiple assets, oswap.io does that for adding liquidity.
