Layer-2 has been quite lively lately, with slogans like "million-level throughput" and "brand new ecosystem" everywhere. However, there is one project that is quite special; it doesn't engage in those gimmicks but focuses on solving several of the most pressing issues for Ethereum users.

The MetaMask wallet you usually use? Use it as usual. The contract code you have written? Basically, no need to change it. Development tools? Still the same familiar set. But what's amazing is that those frustrating experiences—transaction fees that easily reach dozens of dollars, transactions taking ten minutes to confirm, and pages occasionally lagging—have all become smooth.

I met a friend who runs a decentralized trading platform, and he almost had to shut down due to cost issues. His platform has quite a few users, but every time the market fluctuates, the Gas fees skyrocket. One time, a user transferred 100 dollars in ETH, and the transaction fee alone took 8 bucks, leading to a wave of complaints in the community. Later, he tried to migrate the project to this Layer-2 solution, and the entire migration process was completed in less than a day. The contract code remained almost unchanged, and with a slight adjustment to the deployment script, it was up and running.

Now the transaction fees on his platform are mostly just a few cents, and the highest has never exceeded 1 dollar. The user retention rate has jumped directly by 30%. He told me: "I originally thought switching to Layer-2 would require a major overhaul of the product, but I didn't expect it to transition so smoothly, saving me more effort than money."

Regular users feel it more distinctly. There is a guy who often does on-chain operations.
