Still struggling with the exorbitant Gas fees of dozens of dollars and the slow confirmations of Ethereum? There is a Layer 2 solution that might be worth following.

This solution does not play with flashy, impractical PPT technology, but rather addresses several key issues in a down-to-earth manner: the migration cost for developers is nearly zero, transaction fees and waiting times are minimized to the point where you barely notice them, and it can maintain the original security level and privacy protection of Ethereum. Today, let's break down this logic in plain language to see just how practical it really is.

**Biggest selling point? Seamless compatibility with ultra-low barriers**

The technical route chosen is zkEVM. What does this mean? The Solidity contracts you wrote before, the Hardhat or Truffle development tools you are accustomed to, and even the MetaMask wallet, all of them require no changes. Previously, migrating to a new chain meant spending half a month just to modify the code, but now it's basically a matter of copying and pasting. For developers, this saves a lot of effort.

**Costs and speed, directly widening the gap**

The core operation is to throw transactions off-chain for batch processing, and then only submit a zero-knowledge proof to the Ethereum mainnet for verification. The result is that the transaction fees and confirmation times for transfers and interactions have been compressed to very low levels. In the past, making a small transfer on the mainnet could result in Gas fees being more expensive than the principal amount itself; this issue is basically non-existent now.
