Airdrops can be challenging, especially for new users. But don't worry, we're here to help you with our comprehensive step-by-step guide. Just follow this guide to maximize your chances to receive the zkSync airdrop. Even though it may seem a bit tedious at first, the reward often ranges between 1000-10,000$ for just an hour of work. So the time you need is very well invested. Let’s start!

** We recommend to use Metamask wallet browser extension (if you do not have a Metamask wallet then refer to this official guide to download and install the wallet). **

First step: go to https://bridge.zksync.io/ to bridge funds to zkSync Era.

Select ETH, enter the amount (we recommend 0.05-0.1 ETH), and click “Deposit”:

Cross-chain bridging needs more time than a normal transaction, you can see the ETH arriving on zkSync Era chain after about five minutes.

Syncswap link：https://syncswap.xyz/swap

(1) Swap

Connect to your wallet (top right corner), select the ETH-USDC pair, enter how much ETH you want to swap (we recommend to swap ~75% of your available ETH if you have around 0.1), and finally click “Swap”.

Click “Confirm” when the popup pops up:

(2) Provide liquidity

Click on “Pool”, then click on “Pools” to view the available pools. Choose the USDC/ETH pool:

Click “Deposit” on the left, enter the amount (~0.1 ETH and equivalent amount of USDC), you can choose to add both in balanced proportions, then click “Unlock USDT”:

In the popup for authorizing USDC click on “Max” and then “Next”:

Finally, click “Deposit” and confirm this in your wallet as usual once the popup pops up:

(3) Withdraw liquidity

Click on “Withdraw” on the left, click “Max”, click “Permit LP Token” (a popup will pop up asking you to sign, no Gas costs), finally you can click “Withdraw Liquidity”:

(4) Swap back USDC into ETH

After withdrawing liquidity, switch USDC back to ETH (need to go back to “Trade”). Click “Unlock USDT” and follow the same procedure as before (choose “Max”, then “Next”, then “Permit/Confirm”), then click “Swap” and confirm in the popup as before.

Muteswap link：https://app.mute.io/swap

（1）Swap

After connecting your wallet, choose the amount of ETH you want to swap (again we recommend around 75% if your balance is 0.05-0.1 ETH), then click “Swap” and confirm as usual:

（2）Provide liquidity

Click on “Pool”, then click on the “Manage” button of the USDC/WETH (WETH = wrapped ETH, same as the ETH in your wallet) pair.

Enter the ETH amount (it will automatically fill in the corresponding USDC amount needed), then click on “Approve”, after which the process of approving USDC amount (popup choose “Max”, then “Next”, then “Permit/Confirm”) and the deposit into the pool (popup choose “Confirm”) are executed:

(3) Withdraw liquidity

Go to “Withdraw”, click on “MAX”, then click on “Approve”:

After that, approve USDC amount (popup choose “Max”, then “Next”, then “Permit/Confirm”) and the withdrawal from the pool (popup choose “Confirm”) as usual.

(4) Swap back USDC to ETH

Go back to “Swap” USDC/ETH trading pair and swap all your remaining USDC back to ETH:

Finally, approve USDC amount (popup choose “Max”, then “Next”, then “Permit/Confirm”) and the withdrawal from the pool (popup choose “Confirm”) as usual.

Mintsquare link: https://mintsquare.io/zksync

(1)  Mint an NFT

Click on “Mint”: (Note: the mint function might be temporarily disabled, if it is not available then just check the page from time to time whether it is available again. Otherwise there is also an optional alternative described below.)

Upload any picture and choose a name, then click “Mint”.

Click on the profile button on the top right corner of the screen:

Then click on “Profile” to find your newly created NFT.

After selecting the NFT, after clicking “Sell”, click “Unlock”:

(2)  List NFT

Set 0.001 ETH as price, click “List”, when the popup pops up sign the transaction, then the listing is complete.

Optional method if self-minting NFT is not available:

Go to: https://mintsquare.io/explore/zksync/collection

You can browse the collections if there is anything you especially like and want to buy, otherwise the cheapest method is to go to https://app.zkns.domains/ and search for a name which is not popular such as “thisnameistoolong” or something like that. The price can be as low as 0.0028 ETH (5-6$) if you register for 1 year only.

After choosing your name, you can click “Request To Register With ETH” at the bottom of the page to get your ZKNS registered. The ZKNS will be minted as NFT. This NFT will be immediately visible in your profile on Mintsquare. You can then sell the NFT at a price of your choice just as described above for the self-minted NFT.

Note: Two cross-link bridges are used here, one is the official bridge and another one is orbiter.finance.

With the official bridge it will take up to 24 hours to reach the account (!). If you are short of funds, you can use the official bridge to move a little bit of funds, and use the orbiter bridge for most of the rest, which will arrive in a few minutes and you can move on to the next one soon.

(1) Official bridge: https://bridge.zksync.io/withdraw

Confirm it is withdraw, then enter the amount, then click “Withdraw”.

(2) Orbiter Bridge：https://www.orbiter.finance/?source=zkSync Era&dest=Ethereum

Choose zkSync Era-ETH, we recommend not to bridge all the funds, you can leave some in the wallet so that you can still make some trades and other interactions later on. This way you can maximize your chances of receiving the airdrop.

After clicking “Send”, click “Confirm” in the popup.

After the above few projects, the number of interactions is greater than 10. Again, better don't move all your ETH back to the main chain, as you should still keep transacting on the chain about 2-4 times a month.
