ZKSpace Tutorials
I. Preface
ZKSpace is an all-featured Ethereum Layer 2 protocol leveraging ZK-Rollups. It includes three products: ZKSwap, ZKSquare, and ZKSea, covering Layer 2 DEX, Layer 2 wallet, and Layer 2 NFT marketplace.You can view the function introduction and technical scheme on the official website of ZKSpace: zks.org.This tutorial gives a comprehensive introduction to how to use the basic functions of each product.
II. Basic Settings
After connecting the wallet, you can click the gear icon on the upper right corner of https://zks.app to set the slippage tolerance and fee token.Slippage refers to the difference between the expected price of a trade and the executed price of that trade that may be caused by other people trading at the same time. You can set your slippage tolerance on the setting card. Once the price fluctuates more than the percentage you set, your submitted transaction will be declined.Fee tokens are the currency set for the entire ZKSpace platform. You can choose among ETH, ZKS, USDT, and WBTC to pay the gas fee required for various operations on the platform.
2. Language Settings
You can choose your preferred language in the drop-down list by clicking the language name on the top right corner. We are continually adding more languages options to serve a global user base.
III. Layer 2 Wallet
Go to https://zks.app, the web end app of ZKSpace, and you'll see the Layer 2 wallet in the middle of the page. Since Layer 2 is not a brand-new public chain but a scaling solution for Ethereum, the assets on ZKSpace cannot be displayed in plug-in wallets such as MetaMask. For this reason, we provide the Layer 2 wallet, with which users can view and manage their Layer 2 assets.
1. Display of Assets
After connecting your wallet, you can view your assets on ZKSpace. The wallet includes an ERC20 wallet and an NFT wallet, and you can view your ERC20 token assets and your NFT assets separately.
2. Deposit, Transfer, and Withdraw
By clicking Deposit, you can deposit your Layer 1 assets to Layer 2. We recommend you use the default Eco Deposit mode, which is designed to save your time and gas fee;By clicking Send, you can send your Layer 2 assets to any other Layer 2 wallet address. You can enjoy an ultra-low transfer gas fee and ultra-fast confirmation experience (i.e., the ZKSquare product);By clicking Withdraw, you can withdraw your Layer 2 assets to the Ethereum mainnet at any time. We recommend you use the default Fast Withdraw to enjoy faster withdrawal confirmation and lower fees.The above three functions apply to both ERC20 tokens and NFTs.
IV. ZKSwap
As a Layer2 DEX launched at first by ZKSpace, we provide users with a decentralized trading service based on the AMM model. You can access this product via L2 Trade on the top of https://zks.app.
1. How to Trade
Click L2 Trade on the top navigation bar on the homepage. Click Swap in the drop-down menu to open the Swap card. Select the trading pair, enter the amount and click Swap to complete your trade.The current market price of the transaction pair, the price impact that your trade might bring, and the gas fee required will be displayed on the card.ZKSwap provides fast trade confirmation and a far-lower gas fee compared to Layer 1 platform Uniswap.Trading on ZKSwap will also enable you to join the Proof-of-Transaction Mining and get ZKS token rewards.
2. How to Make a Market
Click Pool to provide liquidity and earn the liquidity fee provided by traders. You can click the bar that says Add Liquidity, select two currencies, and make a market by adding liquidity according to the current price ratio.By adding liquidity, you can not only earn the liquidity fee, but also participate in Proof-of-Liquidity mining and get ZKS token rewards.

VI. Mining
You can enter the mining page by clicking Mining on the top navigation bar of https://zks.app. Since 60% of ZKS tokens will be gradually distributed to community users in 4 years, we have currently introduced 7 types of mining activities. They are ZKS Proof-of-Stake mining, Proof-of-Gas mining, Proof-of-Liquidity mining, Proof-of-Transaction mining, NFT Proof-of-Liquidity mining, NFT Proof-of-Transaction mining, and NFT Proof-of-Deposit mining. The rules may be slightly different in different periods. Go to https://zks.app/mining for a detailed description.
1. ZKS Proof-of-Stake (PoS) Mining:
We open 30 days, 90 days, 180 days, or 360 days of ZKS PoS mining activities regularly. You can participate by withdrawing ZKS tokens to the Layer 1 wallet, and locking it into the corresponding smart contract following the guide. There are different APRs for different lock-up duration. Please refer to the event page for details.
2. Proof-of-Gas (PoG) Mining:
ZKSpace will aggregate and package all transactions on the platform and synchronize them to the Ethereum mainnet to ensure the same security as Layer 1. A certain amount of ETH will be consumed every day as the mainnet gas fee. Therefore, we reward users who pay the gas fee to the platform with ZKS tokens through PoG mining.You can deposit ETH on the PoG mining page to participate and get ZKS token rewards on a daily basis. The specific APR may vary slightly according to the actual gas consumed by the platform every day. Please refer to the event page for details.
3. Proof-of-Liquidity (PoL) Mining
As mentioned earlier, users who provide liquidity for ZKSwap can not only earn the liquidity fees provided by traders but also participate in PoL mining to earn more ZKS income.You automatically participate in PoL mining by adding liquidity of the corresponding trading pair. No staking is required. You can withdraw your fund at any time, which delivers a high degree of freedom.We will open PoL mining for different trading pairs at different stages. Please note that when the NFT Boost activity is opened, holding NFTs from specific collections can provide additional bonuses for mining. Please pay attention to the official blog announcement for updates and the event page for details.
4. Proof-of-Transaction (PoT) Mining
Trading on Layer 2 can not only meet your needs for token swaps but also get you ZKS token rewards based on the amount of transaction fee you have paid.We will open PoT mining for different trading pairs at different stages. Please note that when the NFT Boost activity is opened, holding NFTs from specific collections can provide additional bonus for mining. Please pay attention to the official blog announcement for updates and the event page for details.
5. NFT Proof-of-Liquidity Mining
You can participate in NFT PoL mining after adding liquidity to ZKSea. Minting, listing, or successfully selling NFTs enable you to split the daily ZKS token reward. Please refer to the event page for detailed rules.
6. NFT Proof-of-Transaction Mining
You can participate in NFT PoT mining simply by buying an NFT on ZKSea. The reward pool will be shared based on the proportion of your transaction. Please refer to the event page for detailed rules.
7. NFT Proof-of-Deposit Mining
To motivate users to bring well-known Layer 1 NFTs to Layer 2 for trading, we have launched the NFT PoD mining to reward users who deposit specific blue-chip NFTs and list them on ZKSea.You will earn 1,000 ZKS by depositing and listing a single NFT. In addition, when the NFT Boost activity is opened, the NFTs you deposited can also provide bonuses for PoT and PoL mining rewards. Please refer to the event page for detailed rules and supported NFT collections.
Ⅶ. ZKSpace Rate system
Based on the ZKSpace business development plan and the upcoming "ZKS Economic White Paper V2.0", we will adopt a brand-new rate system.
1. Cancel App usage restrictions
The original restriction on the minimum deposit of 50 ZKS or 200 USDT for the APP usage has been canceled. You can now deposit any amount of assets to Layer-2.
2. Cancel free Layer-2 operations
