This is a wrapped version of the $LEO token from Leofinance. It resides on the Polygon blockchain.
It is tied to the Polycub application. There is a liquidity pool where it is traded against $WMATIC.
$pLEO is created by using LeoBridge, which is a cross-chain application. The user feeds $LEO into the bridge and $pLEO is placed in the associated EVM wallet.
