OVERVIEW

NFT AMM Explanation

NFT AMM pools (Non-fungible token Automated Market Maker pools) are a decentralized trading method based on blockchain technology. This type of transaction can increase the liquidity of the NFT market and eliminate the need for intermediaries and exchanges. The NFT AMM pool model is based on the automation of supply and demand and the price calculation to improve transaction efficiency and eliminate the need for price negotiation. This article will provide a detailed introduction to the main features and operations of this model:

Short Intro of EZ Swap:
EZ Swap is developing an NFT DEX protocol that enables games and utility NFTs to trade their NFTs using a native NFT DEX with NFT AMM, meeting games’ needs of market making. Currently, it supports Polygon, ETH, zkSync and Arbitrum.

Main features

1. Pool types:

   1. Trade Pool: Third-party users can buy and sell NFTs through this pool, and the creator of the pool can earn fees from the trading activities of third-party users. This type of pool can provide a way for players holding a large number of NFTs to mine liquidity, create NFT-ETH trading pairs by providing liquidity for NFTs, earn transaction fees, provide a source of income for the big players in the NFT project, and capture better liquidity for the project side.

   2. Buy Pool: Deposit ETH and receive the NFT you want. This type of pool is used for intended buyers to offer for NFT series, and the corresponding NFT holders can sell NFTs to the pool for ETH at any time. Liquidity can be added by sending ETH to the created buy pool and creating new buy pools.

   3. Sell Pool: Deposit NFTs and exchange for ETH. NFT holders can sell their NFTs by listing them in this pool. Liquidity can be added by adding NFTs to the created sell pool and creating new sell pools to list NFTs.

2. Price change model

   This model can automatically adjust the selling price of NFTs and the offer price, and can be easily used for batch selling NFTs and batch offering, and can adjust the price according to market conditions.

   1. Exponential: The price of the next NFT automatically changes exponentially after each transaction, and the price changes dramatically.

   2. Linear: The price of the next NFT automatically changes linearly after each transaction, and the price changes smoothly.
