# DeFi

$WINS is based on Ethereum, but most activity will likely take place on Polygon PoS.  Our project-supported liquidity pools are set up on Polygon, and Trophy's revenue-based purchases will take place there.

$WINS is tradable on Decentralized Exchanges (DEXs) like [Uniswap](https://app.uniswap.org/#/tokens/polygon/0x1a49e59ab7101d6a66d6b2fa6d09932079cc80ec).  Liquidity is deepest on Polygon PoS trading pairs.

$WINS is also tradable on some centralized exchanges (CEXs).  Note that, since $WINS is based on Ethereum, most of these exchanges will use Ethereum $WINS rather than Polygon $WINS that is awarded via Trophy app.

To move $WINS between Ethereum and Polygon, be sure to use the [Portal Bridge, built by Wormhole](https://www.portalbridge.com/#/transfer).  Do NOT use any other bridge, including the native Polygon PoS bridge, as that will not work.  The version of $WINS supported on Polygon uses the Portal Bridge.
