On the evening of March 1, Beijing time, Matter Labs, the Ethereum ZK Rollup expansion solution construction team, announced the completion of the A round of financing. Union Square Ventures (USV) led the round. Previous investors Placeholder, 1kx and Dragonfly continued to participate in this round. In addition to participating in this round of investment are zkSync’s ecological partners, including Aave, Balancer, 1inch, Curve, Binance, Coinbase Ventures, Huobi, Loopring, Argent, MYKEY, imToken, Flexa, MoonPay, ripio, ZKValidator , CoinGecko, the specific financing has not yet been disclosed.

As early as the end of December last year, Alex Gluchowski, CEO of Matter Labs, confirmed that the team’s ZK Rollup expansion plan, zkSync, would launch a native token (according to the Rinkeby test network, the token should be called MLTT, and the faucet is currently closed).

With the completion of this round of financing, the speculation about zkSync’s imminent coin issuance has sparked extensive discussions in various communities. Although it is not yet sure whether there will be an airdrop of zkSync tokens, and if so, what are the specific standards, but in line with the principle of "I would rather be busy than miss it", it is never wrong to interact with the zkSync contract in advance. A little gas fee (the current total cost is about tens of dollars), and a big red envelope, why not do it.

In this article, we will teach you the specific method of interacting with the zkSync contract, or that sentence,secondary title

Step 1: Preparations

First of all, you need to install a Metamask wallet plug-in (currently other wallets are also available, but for the wool party, Little Fox is obviously the most convenient). There are many tutorials on how to install it on the Internet. Note that you need to put some ETH in the wallet as a gas fee , select the Ethereum main network as the network.

Then, you need to enter the official address of zkSync "https://zksync.io/secondary title

Step 2: Deposit

After completing the link, you will enter the main interface of zkSync. At this time, the interface will show that you have no balances on the second layer network of zkSync (no balances yet), and you need to deposit or ask others to transfer money to your address.

You can deposit your own funds on the first-tier network (that is, the original Ethereum chain) into the second-tier network of zkSync, and use the ETH prepared in the previous step for the funds, but remember that you still need to leave a small amount of ETH in the wallet as the gas fee .

Click "+Deposit", and you can deposit freely. You can click "Select token" to select the currency you want to transfer to the second layer, and enter the corresponding amount in the horizontal box.

Step 3: Transfer

After the previous step is completed, you can see your balance on the second layer network of zkSync, and you can continue to experience the transfer function.

If you are interacting with other friends, two people can transfer to each other at this time;

It should be noted that before the transfer, we need to register the public key, that is, activate (Activate). This step still needs to consume a certain amount of gas for the time being. Matter Labs has also stated that it will try to eliminate this link in the future.

After the activation is complete, you can see that part of the balance in the second-tier network has been deducted at this time, which serves as the gas fee for the previous link.

Then you can transfer money freely. Let me turn my left hand to my right hand as an example. As shown in the picture above, I transferred 0.03 ETH to the address ending in 365d, and the gas consumption is about 0.12 US dollars, which is indeed much cheaper than the first-tier network. The transfer will be confirmed in seconds, and the transaction records (including previous deposit records and activation records) can be viewed under "Transactions" on the main interface.

Step 4: Another method of transfer - ZKlink (although I didn't get it working myself)

In addition to conventional transfer methods, zkSync also provides a method calledZKlinkThe payment method is still the same sentence - "We need to try our best to experience all the functions currently supported by zkSync", so you can also try using ZKlink to transfer money.

As shown in the picture above, you can fill in your left-hand address in the "Receiver ETH address", then select the desired currency and amount, and then click "Create your payment link" to create a payment link.

Step 5: Withdraw

Finally, there is the withdrawal link. As the name suggests, it is to transfer funds from the second-tier network back to the first-tier network. The operation is very simple. After clicking "-Withdraw", it will automatically jump to the interface. The address at this time is the wallet address you are currently linked to. , you are also free to choose to mention to other addresses.

Step 6: Come on, let’s play the zkSync version of Curve

Curve, a well-known stablecoin exchange platform, has integrated the zkSync expansion solution on Ethereum’s Rinkeby test network. In line with the principle of “I’d rather work in vain than miss it”, you can give it a try.

First, you can open the zkSync version of the Curve application address "https://zksync.curve.fi/", as shown in the figure below after clicking.

Conclusion: entertainment mentality

The super airdrops of Uniswap, The Graph, 1inch and other star projects last year made countless people rich overnight. "Exchange the contract address of unissued projects in advance" has also become the consensus of all wool parties. Many well-known DeFi products, such as dydX, Matcha, and today's zkSync have long been on the sniper list of the wool party.

However, as mentioned at the beginning, it is not yet certain whether zkSync tokens will be airdropped. Even if there is, the specific standards have not yet been made public, and no one knows whether the interaction methods provided in this article can meet the conditions.

The above only provides the interaction method with zkSync, and it does not mean that you will be able to get the airdrop. Friends who are interested and have sufficient funds may try to spend tens of dollars in gas fees to go through the process, but use multiple addresses and high costs to generate volume It is unnecessary.

Wool is risky, please judge whether you should squeeze it or not.
