POE (PropAMM)
POE is a Prop-AMM that combines multivenue-driven pricing to deliver the most accurate and efficient swaps.
What is a Prop AMM?
Proprietary AMMs are liquidity pools where the price is computed by aggregating multiple sources, rather than relying on reserve ratios alone. This approach is highly capital efficient: overcoming traditional liquidity pools impermanent loss and MEV extraction.
POE's approach: Vaults provide liquidity, while POE handles pricing quotes. This separation enables capital-efficient swaps with deep liquidity.
How POE Works
POE is built on OraclePool — a smart contract implementing the Concentrated Liquidity Constant Product (CLCP) model.
The Two-Layer System
| Layer | Who | Role |
|---|---|---|
| Pricing | Market Maker (Oracle Operator) | Sets reference price, concentration range, and fees |
| Liquidity | Community (Anyone) | Deposits tokens, earns swap fees |
Price Calculation
The execution price comes from both components:
- Oracle data — The operator sets a center price (P) and concentration factor (α), defining the price range [P/α, P×α]
- Pool reserves — Determine the exact price within that range based on supply/demand
This hybrid model keeps prices tight to market while maintaining permissionless trading.
Why POE?
- No traditional impermanent loss — Algorithm-driven pricing protects liquidity providers
- No MEV leakage — Prices update faster than arbitrageurs can extract value
- Fast price updates — Price feeds are updated and aligned with external markets
Key Features
Best Execution Price
Algorithm-driven pricing keeps execution prices tightly aligned with external markets, delivering better rates than traditional AMMs.
High Throughput
Designed for volume. The gas-efficient oracle update mechanism supports high-frequency price adjustments without excessive costs.
Easy Integration
Callback-based swap interface enables straightforward aggregator integration and composability with other DeFi protocols.
Network
POE is deployed on Monad, a high-performance EVM-compatible blockchain where the gas economics make frequent oracle updates viable.
