Bridging
The $DERC token is available on Polygon, Etherium and Binance Smart Chain, but all DeRace game transactions will be carried out on Polygon.
A bridge is used to transfer tokens from one blockchain to another.
Anyswap
Anyswap is the official DeRace recommended way to bridge $DERC to Polygon. Anyswap allows you to bridge many different tokens across many networks.
Polygon Bridge
Polygon has its own bridge which can be used to transfer tokens between Etherium and Polygon.
