NFTs are traded for cryptocurrency.
Funrise operates on the Polygon blockchain, which contains many cryptocurrency tokens, from the usual BTC and ETH found in other blockchains to polygon-specific tokens that exist only inside the $POLYGON$ Polygon blockchain.
We use $USDC$ USDC (Polygon) for all transactions on the site so that our users do not have to think about fluctuations in cryptocurrency rates because one USDC is always equal to one US dollar ($).
Soon, Funrise will also accept $FNR$ FNR (Funrise) tokens as a means of payment. Stay tuned!
