Amun's Polygon Ecosystem Index, or PECO, is an ecosystem token that consists of the leading projects on Polygon. Its purpose is to give investors an opportunity to track a range of different tokens in a particular ecosystem based on market capitalization, akin to buying an ETF that tracks the S&P.
This index consists of the top performing tokens native to the Polygon blockchain, allowing users on Ethereum to gain exposure to these projects without having to bridge funds over to a separate network
