Recently, Polygon Lianchuang Sandeep Nailwal responded to comments on social media about "Zk hype far exceeds actual user demand", saying that the Polygon zkEVM ecosystem is providing critical infrastructure such as safe, oracles such as Chainlink, and early developer feedback. Sufficient preparations have been made for UX improvements, cost optimization using data compression, etc., and there are no regulations stating that issued tokens cannot be used for large-scale airdrops. It cannot be denied that Polygon will never lack for mass adoption.

As you can probably guess from the above, Polygon zkEVM is not just the expected airdrop hype, there is a high probability that there will be large-scale airdrops in the future, and Sandeep also mentioned "first it will rain, then it would POUR", it seems that zkEVM is now in front of a downpour. drizzle stage. For Polygon zkEVM, we must seize the time to interact.

Introduction to Polygon zkEVM

Polygon zkEVM is an Ethereum Layer 2 zkEVM expansion solution based on ZK Rollup technology. ZK Rollup uses "zero-knowledge proof" verification to implement Rollup's expansion solution.

Under the ZK Rollup expansion plan, off-chain (Layer2) executes transactions and completes complex calculations. After batch processing, compression and packaging of multiple transaction data, a "zero-knowledge proof" result of the off-chain calculation will be created and submitted to the main network (Layer1). ) to perform proof verification. Mainnet verifiers can quickly check whether the proof is correct and store the data part on the mainnet, sharing the security of the mainnet.

DefiLlama data shows that as of publication, Polygon zkEVM TVL has reached US$2.89 million.

Currently, Polygon zkEVM does not support many projects. This article selects three applications for interactive experience. Next, I will bring you an interactive tutorial on Polygon zkEVM.

Polygon zkevm interaction

Add networks and bridges

First, enter Chainlist to add a network and select Polygon zkEVM to add to the Little Fox wallet;

Enter the Polygon zkEVM Bridge website, connect to the Little Fox wallet, and select the amount of the cross-bridge from the Ethereum mainnet to Polygon zkEVM.

There is a terms of use at the bottom of the interface. You need to enter "I UNDERSTAND" in the space before you can perform cross-bridge operations. It should be noted that manual input and copy-paste are not feasible;

However, the current Gas of Ethereum mainnet or L2 across Polygon zkEVM through the official bridge is relatively high. In addition, you can also choose a third-party cross-chain app for cross-bridge operations. It is recommended to use Bungee or Orbiter;

It has been verified that Orbiter Gas is slightly lower than Bungee, so this tutorial selects Orbiter as the cross-bridge app;

interaction

QuickSwap

After the bridge crossing is completed, interact with Polygon zkEVM, click on its official website, select ETH-USDC swap and ETH-MATIC swap according to your own amount, and the wallet is authorized for approval (it is recommended to select a quarter of the total amount of ETH for swap);

Next, click on the pool and select the ETH-USDC (according to the token pair of your choice) trading pair to add liquidity;

Select Manual, select the corresponding ETH and USDC to Preview after approval;

After completing the above steps, you can see your LP.

0VIX

Next, use the 0VIX protocol, click on the 0VIX official website, connect to the wallet, and confirm that the network is Polygon zkEVM;

Click MATIC-Supply in Supply Markets, select 10 MATICs and confirm; then click MATIC-Borrow in Borrow Markets, select 7 MATICs and confirm.

Then click Repay all funds in Borrowed Assets, and then click Withdraw all funds in Supplied Assets.

DoveSwap

DoveSwap is currently the second-ranked DEX on Polygon zkEVM. Its interaction process is also very simple. Select ETH-USDC swap, then click Pools to add liquidity according to your own asset conditions.

After completing the above steps, you will be able to obtain the number of nearly 20 transactions on Polygon zkEVM. Check the transaction status in the Polygon zkEVM browser. Pay attention to Gas consumption and network selection. In addition, this tutorial requires patience.

Conclusion

In the future, Uniswap and AAVE will also be integrated into Polygon zkEVM, which is expected to be launched in a few weeks; and Immutable is also working with Polygon Labs to build Immuable zkEVM, a game-specific chain using zero-knowledge technology. Perhaps as Sandeep said, "first it will rain, then it would POUR", I look forward to integrating Polygon zkEVM with more applications, and I also look forward to users who interact with it getting paid a lot of money.
