# ZKSea Tutorials

## **1.Preface**

After the brand upgrade, we launched the Layer-2 full-featured protocol ZKSpace, which includes all the functions of the ZKSwap V2 version, and added ZKSea products to support all the NFT functions of Layer-2.

This tutorial will not repeat the basic functions of the ZKSwap V2 product, but mainly introduces the changes in the new version and the steps to use ZKSea.

## 2.ZKSea

### a. Preliminary preparation

Log in to the ZKSpace WEB APP: zkspace.app.

ZKSea is a Layer-2 NFT product based on ZKSpace. You can only use the funds in the Layer-2 wallet for NFT trading. Make sure you have a certain amount of funds in your Ethereum Layer-2 wallet.

Please refer to the "[ZKSwap V2 Tutorials](/tutorials/zkswap-v2-tutorials.md)" for the procedures of wallet connection and asset deposit/withdrawal.

### b. NFT wallet

You can enter the NFT mall through the NFT Market button on the navigation bar, which provides NFT purchase, minting, and other services. Details of your Layer-2 NFT record can be found in your NFT Wallet.

The above image shows what the NFT Wallet would be like. All NFTs owned by you will be displayed in your NFT Wallet. The deposit, transfer, and withdrawal of NFTs are the same as ERC-20 tokens.

In the NFT Market, parts of the ZKSpace functions on the navigation bar are hidden to fully display the NFT-centered options.

Discover your favorite NFTs in the NFT Market. Remember to check out the details of an NFT before making a payment.

### d. User Page

Before minting an NFT, you need to enter the User Page in the upper right corner to complete the author information, including the avatar, nickname, personal introduction, etc.
