Why Build on Kroma?

Vision — Kroma has the similar vision with Ethereum.

Kroma shares a similar vision with Ethereum, aiming to provide a decentralized platform for building and deploying blockchain-based decentralized applications (dApps). Limited TPS on Ethereum has led to scalability issues, and as a solution, Layer 2 (Rollup) technologies have emerged. We are dedicated to contributing to the growth of the blockchain by establishing our own core values and, ultimately, helping Ethereum achieve its goals in a more seamless and efficient manner.

Cost — Kroma saves users gas fees.

Gas fees are requested to send transactions on a blockchain network. As a rollup technology, Kroma reduces the amount of gas needed, which lowers the fee burden for users. This makes it more cost-effective for developers to deploy their dApps, ensuring a smoother and more affordable development process.

Open source — Kroma brings users and builders together.

Kroma is dedicated to promoting an open-source culture. Uniting developers and builders is essential for achieving mass adoption of blockchain technology. By adhering to the principle of maximum transparency when disclosing our source code, we strive to create an environment that allows anyone to contribute effortlessly to our project and share their ideas. This approach aims to cultivate a sense of shared ownership, ultimately helping us develop a more mature Layer 2 ecosystem.
