We launched v2 of NFT Protocol into a public beta phase on April 21, 2022. This version of NFT Protocol requires that swap creators send their assets involved in the swap to the protocol where they are held in escrow awaiting a taker by paying gas for an on-chain transaction. We chose this architecture because it allows the protocol to operate entirely on-chain and limits attack vectors in pretty significant ways relative to the hybrid on/off-chain protocols that power most other NFT marketplaces and trading platforms. This architecture is a great fit for creators who mint from their own contract, intend to list and sell their creations at a fixed price, and simply need a safe and affordable means of listing their creations for sale.
