Axie Infinity Origin will be a big change for the Axie ecosystem. And with it comes the need for improvements to their marketplace. Most notably, this update allows the market to work with ERC-1155 tokens. The main differences between ERC-1155 and the more well known ERC-721 standard, is that ERC 1155 supports bulk transactions and transfers, making swaps of multiple tokens easier and cheaper. This is very similar to the SFTs from Genopets that were recently added to the Magic Eden marketplace. The purpose is to have NFTs that exist in large quantities, and see lots of trading activity, without putting undue stress on the system, the user, or the blockchain.
