### What is the ETH 2x Flexible Leverage Index (ETH2x-FLI-P)?

The Polygon-native version of the ETH 2x Flexible Leverage Index abstracts collateralized debt management into a simple index, reproducible by an ERC20 token built on Set Protocol. ETH2x-FLI-P enables you to get leveraged exposure to Ether using collateralized debt, without having to manage collateralized debt positions or monitor liquidation risks. ETH2x-FLI-P targets a long 2x exposure to MATIC and employs a flexible leverage mechanism for optimal rebalancing outcomes.

### What is the methodology behind ETH2x-FLI-P?

The methodologist behind the FLI is Pulse Inc. (DeFi Pulse).
