  • Gaming

    Building a web3 experience that needs to mint millions of assets and onboard many users? Don’t worry about costs. You can defer, and reassign the payment of gas fees for these assets to match your unit economics.

  • Creator marketplaces

    State of the art web3 experiences need to abstract away gas fees for users. Creators can list their collections for sale without having to pay any gas fees. Imagine if gas fees only happen when a sale takes place. Fees can be subsidized by anyone with any token.
