Project Mariana

Central bank digital currencies - Bank for International Settlements (BIS) - decentralised finance (DeFi).

Project Mariana was launched in 2022 as a joint initiative of the Eurosystem, Singapore and Switzerland BIS Innovation Hub Centres together with the Bank of France, Monetary Authority of Singapore and Swiss National Bank.

It is established to explore automated market makers (AMM) for the cross-border exchange of hypothetical Swiss franc, euro and Singapore dollar wholesale CBDCs.

Improving cross-border payments

"Project Mariana uses DeFi protocols to automate foreign exchange markets and settlement, potentially improving cross-border payments...

Today, DeFi built on public blockchains uses smart contract protocols to automate markets for crypto and digital assets.

AMM protocols combine pooled liquidity with innovative algorithms to determine the prices between two or more tokenised assets.

In the future, similar AMM protocols could form the basis for a new generation of financial infrastructures facilitating the cross-border exchange of CBDCs."
