4 min readMay 16, 2024


Rubic is your one-stop shop for accessing Layer 2 chains. We’ve already integrated 16 Ethereum Layer 2 networks, including Kroma! This integration, facilitated by Orbiter Finance and iZUMi Finance, allows for seamless swapping to Kroma on Rubic with cost-effective rates and faster transaction speeds.

What Is the Kroma Network?

Kroma aims to develop a universal ZK Rollup based on the Optimism Bedrock architecture. Currently, Kroma operates as an Optimistic Rollup with ZK fault proofs, utilizing a zkEVM based on Scroll. The goal of Kroma is to eventually transition to a ZK Rollup once the generation of ZK proofs becomes more cost-efficient and faster.

Kroma boasts several compelling advantages:

  • Significantly Lower Fees: Kroma offers transaction fees that are 10x lower compared to the Ethereum mainnet, making it a cost-effective option for users.
  • Uncompromised Security: Kroma leverages the native security of the Ethereum network, ensuring a safe and reliable environment for your transactions.
  • EVM Compatibility: Kroma is EVM-equivalent, meaning existing Ethereum tools and applications work seamlessly on its platform.

Additionally, Kroma’s tokenomics incentivize user participation:

  • 7% Token Rewards: Kroma allocates 7% of its total token supply to reward explorers and users who contribute to the network’s growth. This encourages active participation and community building.
