The cryptocurrencies involved in KRL, known as $KRL and $EoC, are situated on the Polygon network.
The KRL tokens are both based on the ERC-20 Token Standard. These can be bought and sold, or swapped, on exchanges. To transfer these assets, you will need to have an ERC-20 compatible wallet such as MetaMask.
To send the KRL tokens from a wallet to an exchange, or from a wallet to another wallet, you will need to pay the transactions fees in Ether (ETH), which is the he native cryptocurrency of the Ethereum platform and which acts as fuel for the network.
Racer NFT Characters
The unique-looking Racer creatures in KRL are all based on the Polygon blockchain as well.
The characters use a newly-emerging technology called NFTs (or non-fungible tokens). An NFT is a unit of data stored on a blockchain that certifies a digital asset to be unique and therefore not interchangeable.
