Overview
Quantillon Protocol
Overview
FX-hedged local-currency infrastructure for DeFi
🧭 Welcome to the Quantillon Protocol Documentation
Quantillon Protocol is a currency-agnostic DeFi architecture designed to turn deep USD liquidity and yield into local-currency exposure. Instead of asking users to hold raw dollar risk just to access DeFi, Quantillon inserts a protocol-native FX hedging layer between USD liquidity and the user-facing asset.
QEURO is the first deployment of that architecture. It proves the model on EUR first, while the protocol itself is designed to support additional markets when governance, hedger participation, and economics justify expansion.
🎯 What Quantillon Is
Quantillon is built around four reusable layers:
USD liquidity and yield sources as the economic base layer
A protocol hedging engine that absorbs the FX leg
A local-currency asset layer for the market being served
Governance, wrappers, and risk controls that can be reused across deployments
This documentation is therefore split into two perspectives:
Protocol Foundation: the generic architecture and economic logic
QEURO: First Deployment: the current EUR implementation of that architecture
💶 QEURO Is the First Proof Point
Quantillon starts with the euro because it is one of the clearest non-dollar markets in DeFi:
Strong demand for local-currency exposure
Deep EUR/USD hedging infrastructure
A clear mismatch between local-currency users and USD-denominated yield
QEURO should be understood as the first production deployment, not the full definition of Quantillon.

💡 Why This Matters
Most DeFi liquidity still lives in dollar-denominated markets. For users, treasuries, and protocols that think in EUR, CHF, JPY, GBP, or another local currency, that creates a structural problem:
the best liquidity is in USD
the best yield is often in USD
but the desired balance-sheet exposure is not necessarily USD
Quantillon is built to close that gap.
