Automated Market-Making for Fiat Currencies

Abstract

We present an automated market-making (AMM) cross-settlement mechanism for digital assets on interoperable blockchains, focusing on central bank digital currencies (CBDCs) and stable coins. We develop an innovative approach for generating fair exchange rates for on-chain assets consistent with traditional off-chain markets. We illustrate the efficacy of our approach on realized FX rates for G-10 currencies.
