The new DESK is an ERC-20 standard token on the mainnet, or live version, of the blockchain. However, to avoid congestion on Ethereum, the revamped DESK runs on Polygon. This is a sidechain, or parallel network, to Ethereum that allows more and cheaper transactions by keeping them off the primary chain. CoinDesk will cover the cost of gas, or on-chain computation fees, for DESK transactions on Polygon.
