zkApes is a metaverse project that is built on the zkSync Layer 2 scaling solution for Ethereum. The project involves developing 9999 dynamic NFTs (dNFTs), with each Ape being original and unique. The project is developing a metaverse called Apeverse where users can exchange their dNFTs, play games, and make money.

The Apeverse products that are being developed include Apescan, ApesdNFT, ApesBank, ApesDomains, ApesArcade, ApesDAO, ApeX, and zkApe AMM-Dex. One of the exciting products that zkApes is developing is ApeX, an Automated Market Maker (AMM) protocol built on zkSync. ApeX allows users to swap NFTs for tokens and vice versa using customizable bonding curves. The protocol supports ERC721 NFTs, as well as all ETH and ERC20 tokens.

Liquidity providers can deposit assets into one-sided buy and sell pools or two-sided trading pools that buy and sell NFTs with optional spreads for transaction fees. ApeX does not distinguish between different ERC721 IDs, so pools will return the same price regardless of which NFT is sent to or from the collection.

ApeX works by allowing liquidity providers to deposit NFTs and/or ETH (or an ERC20 token) into liquidity pools. They choose whether they would like to buy or sell NFTs (or both) and specify a starting price and bonding curve parameters. Users can then buy NFTs from or sell NFTs into these pools, and every time an item is bought or sold, the price to buy or sell another item changes for the pool based on its bonding curve. Liquidity providers can change the parameters of their pool or withdraw assets at any time.

The bonding curve is a mathematical formula that defines the relationship between an asset's price and its supply. Bonding curves are a key feature of automated market makers since they are used to algorithmically adjust asset prices. At launch, ApeX supports two types of bonding curve: linear and exponential.

With a linear rise, the price of an NFT is increased by a flat amount (called rise) every time an item is bought from the pool. Conversely, the price of the NFT is decreased by that same flat amount every time an item is sold to the pool. With an exponential rise, the price of an NFT is increased by a certain percentage (also called rise) every time an item is bought from the pool. Conversely, the price of the NFT is decreased equivalently every time an item is sold to the pool.

In conclusion, zkApes is an exciting metaverse project that is leveraging the benefits of zkSync Layer 2 scaling solution to develop a unique collection of dNFTs. With Apeverse and ApeX, zkApes is set to offer users an exciting new experience in the world of NFTs, where they can exchange their dNFTs, play games, and make money. The use of bonding curves on ApeX is an innovative approach that will help to maintain liquidity and algorithmically adjust asset prices. It will be interesting to see how the project develops and the impact it has on the NFT ecosystem.
