What is Wrapped Ether (WETH) and how do I use it to make offers?

Wrapped Ether (WETH) is required to make an offer on any NFT in the Mapstone Marketplace. WETH allows users to make pre-authorized offers that are fulfilled at a later date if a willing NFT owner agrees to the offer price. If an offer is accepted, no further action is required from the initial offerer to faciliatate an NFT sale and transfer.

WETH is minted when a user sends ETH to the WETH decentralized, open-source smart contract. The smart contract holds the ETH sent by users and mints an equivalent amount of WETH.
