The company wrote in a blog post that the marketplace allows users to tokenize time into an NFT on the Polygon sidechain. Moreover, all the work and events are recorded on the blockchain network.

Time is our most valuable asset. We each hold a limited supply of time, but how we use it, what we use it for and for what price we sell it sometimes feels out of our control.

Users already flooded the marketplace with a variety of different services in exchange for crypto. For example, some sell copyrights for classical music performances in the form of an NFT, the others design the sandbox assets of the "world-class level of quality." The marketplace supports deals in MATIC, USDC and wETH.
