If we compare the Ethereum mainnet to an ancient but bustling city, then Kite is like a newly emerging fully automated new town nearby. Both use the same programming language (Solidity) and the same asset unit (ETH), but if you operate an autonomous racing car with experience from the old city, at best your performance will be discounted; at worst, you might "flip over" because you didn't understand the new rules.

By the end of 2025, EVM compatibility will be a basic operation, but "completely identical" is often just a developer’s wishful thinking. As a deeply optimized execution layer, Kite has several invisible but critically important "dividing lines" between its underlying logic and the Ethereum mainnet.

First, let's talk about the differences in Gas cost calculation, which is the multi-dimensional Gas model issue.

On the Ethereum mainnet, Gas is like a universal ticket—you pay the same Gas whether you're performing complex calculations or inserting data into a contract. But to pursue maximum throughput, Kite has implemented a more granular resource pricing mechanism. The fee strategies for state access and computation differ significantly between Kite and the mainnet.

Many developers are accustomed to frequently using the SLOAD instruction to read on-chain data on the mainnet because Gas consumption there is relatively predictable. However, on Kite, due to more efficient optimization schemes, this old experience may no longer be applicable.
