Supplement: 2 Task 3 has been completed (Task 4 is not done). Correction: It takes 24 hours for zksync to withdraw coins back to the exchange.
Event time: 00:00:00 on April 15, 2024 to 23:59:59 on April 28, 2024 (UTC)
Note: This activity explicitly requires the use of a backup wallet created using the native Binance Web3 wallet. Externally imported wallets do not meet the requirements.
I didn't want to do this airdrop activity at first, I don't like the lucky draw airdrop, but later a fan asked me, I also want to try the zkSync airdrop (I'm not sure if the snapshot has been taken, and even if it hasn't been taken, I'm not sure if there will be an airdrop after two interactions), so I did this tutorial. From withdrawing coins from the exchange to completing the first three tasks, the cost of withdrawing coins back to the exchange is about 0.00141 ETH (based on 3020, about $ 4.26, including gas fee of 0.000547 eth, 3 times on-chain exchange rate wears out 0.00088 eth, the ether fluctuation is too big and it's a bit painful, if you really want to do these tasks, it's best to wait until it stabilizes).
This activity is quite annoying. After completing the task, I am not sure whether I have completed the task... In the end, I don’t recommend doing it. I have simply calculated the cost and can see from the above that except for task 3, the other tasks are in the form of lottery, which means that some people will be cheated.
There are 4 tasks in total, all of which are one-time tasks, and the prize pools are also independent:
0. Click "Join Now" on the event page to sign up for this event.
Task 1: Use the built-in "Exchange" function of Binance Web3 wallet to perform cross-chain exchange. The target token must be: USDC (zkSync Era chain), and the final exchange amount must be greater than or equal to 10 US dollars. This prize pool is 20,000 USDT, and 2,000 people who meet the matching rules will share it equally, that is, the "selected people" will receive an average of 10 USDT airdrop.
Task 2: Use the SyncSwap application to exchange more than 100 USD in a single transaction through the three trading pairs of ETH/USDC, USDC/USDT, and wstETH/ETH. The prize pool is 20,000 USDT, and the 400 people who meet the matching rules will share it equally, which means that the "selected people" will receive an average of 50 USDT airdrop.
Task 3: Use the ZeroLend application to provide collateral of at least $10 on the zkSync chain: ETH, DAI, LUSD, USDE, USDT, WBTC. The prize pool is 20,000 USDT, and all those who complete this task will share it according to: (value of the user's own collateral/value of all users' collateral)*20,000. This task is a bit ambiguous. There is a loan task in the official tutorial, but it is not explained in the task. I also joined the official discord, but no project staff responded for a long time, so I quit directly. It was a waste of emotion. In fact, the project also has an airdrop event. I wanted to participate, but I gave up directly after seeing the attitude of the project party.
Task 4: Don't do it, the probability is too low, and there should be no cost, there will be a lot of people participating in this task. After opening the ladder yourself, reopen the program and read the official tutorial.

Task 1: There is an official tutorial. Slide to the task, and then you can see "Please refer to the tutorial here" on "Exchange Now". Click "Here" to jump to the corresponding tutorial. Be sure to "register" to participate in the event before doing the task to avoid wasting gas. The total cost is 0.0003874 eth ($ 1.2 based on 3020) (withdrawal fee + exchange gas).
My plan: Because there are no assets with a value greater than $10, such as USDC in the tutorial, on the chain, so I transferred assets from the exchange. I don’t know if it’s because of the conversion in the middle or because of the cross-chain, the fee is a bit high... First buy about 15-16 FDUSD on the exchange (fdusd’s ETH trading pair is free of handling fees), then buy ETH worth about $15, and then withdraw it to the "Optimism" chain wallet address of the "Binance Web3 Wallet". Then use the exchanged "Payment Token" to select ETH of the OP chain, and "Receive Token" to select the USDC token of ZKS. Note: Make sure that the minimum amount of the payment is greater than or equal to $10 (preferably greater than 10.01 USDC). Although the exchange page says that no cross-chain fee is required, it is actually required, and it is also quite expensive, with a gas fee of 0.000358 ETH.

Task 2: There is an official tutorial. Slide to the task, and then you can see "Please refer to the tutorial here" on "Exchange Now". Click the "here" link to jump to the corresponding tutorial. (Ignore if you have already registered) You must "register" to participate in the event before doing the task. The total fee is 0.000055 eth (about $ 0.17 based on 3020). (Withdrawal fee + exchange fee)
My plan: Because there is no gas token eth on the zkSync chain, and for ease of operation, the subsequent exchange also uses eth/usdc, so that tasks 1 and 3 can be combined together. First, buy about 105 FDUSD on the exchange (fdusd's eth trading pair is free of handling fees), then buy all ETH, and then withdraw to the "zkSync" chain wallet address of the "Binance Web3 Wallet".
When withdrawing coins, remember to list the tokens on the zkSync chain first to facilitate subsequent operations.
When exchanging, remember to link your wallet and select the zkSync chain.

Task 3: There is an official tutorial. Slide to the task, and then you can see "Recharge Now" with "Please refer to the tutorial here". Click the "here" link to jump to the corresponding tutorial. (Ignore if you have already registered) You must "register" to participate in the event before doing the task. Total fee 0.0000945 ETH (about $ 0.29 at 3020, authorization fee + deposit + withdrawal)
My solution:
After entering the application page, remember to switch to the zkSync chain, remember to switch in both places, and then connect the wallet.
Connect your wallet, scroll down to usdc, and click “view detail”
Then click "your info" and click "supply"
Enter the deposit amount (can be max), during which you need to authorize the contract to operate with unlimited amount. After authorization, click "supply usdc" to complete the deposit.
There is a little interest on deposits, as well as points for airdrop activities. If you just want to complete the task, you can withdraw the money directly. Click the menu icon in the upper right corner, then click "dashboard", you can see your assets, you can see that there are assets under USDC and you can "withdraw", just click it, and the withdrawal is completed.
The last step: cost about $0.1
Exchange all the usdc into eth through the previous syncswap (because the exchange does not support the usdc of the zksync chain), then keep a little eth for gas, and deposit the rest back to the exchange. The speed of recharging the zkSync chain to the exchange is really slow (it takes 24 hours). If the funds are urgently needed, it is recommended to cross the chain back to the original chain (you don’t need to exchange it into eth, just usdc, Binance supports usdc of OP and arb chains). Although it costs 1-2u cross-chain fees, it is much faster.
