We're thrilled to announce that RARI Chain — a dedicated creator-first Arbitrum Orbit L3 built with Caldera — is now live on mainnet! With this deployment, NFT creators will finally have access to a performant infrastructure layer that truly prioritizes creator compensation by bringing royalties into the foundation of every project launched on it.

Introducing RARI Mainnet

RARI Chain is an EVM equivalent blockchain powered by Arbitrum Orbit that offers low costs, fast transaction times, and a node-level embedded royalty structure that prevents common smart-contract overrides and allows creators to freely set unique royalty rates on their NFT. This structure protects creators from transactions that might attempt to circumvent royalty payments, and ensures that they benefit from their work!

Powerful Developer Tools

RARI Mainnet comes equipped with thirdweb's full web3 developer stack, offering comprehensive tooling across wallets, contracts, payments, and infrastructure for every developer building on RARI Chain.

We're proud to share that starting today, the thirdweb toolset will be available across every Caldera chain, providing unparalleled DevEx and industry-leading tooling to the next thousand EVM rollups launched in our ecosystem.

Low Costs, Lightning Fast

In addition to its creators and developers, RARI Mainnet is also very much built with collectors in mind.

Thanks to an integration with Arbitrum Anytrust, any and all transaction fees on RARI Chain cost less than 1 cent, enabling users to mint, buy, and trade NFTs with virtually-zero associated gas costs . On top of that, RARI Chain allows users to make purchases in ETH, UDSC, or USD via credit card for maximum ease of use.

RARI Chain is also lightning fast. With blocks confirmed every 250 milliseconds, it's able to process between 200-500 transactions per second, ensuring that you don't have to wait around for your purchase to finalize while maintaining the same security as an Ethereum transaction!

How Caldera supports RARI Chain

At Caldera, our goal has always been to help innovative teams like the RARI Foundation bring their ambitious goals to life. RARI Chain is another testament to that commitment.

We're incredibly proud to have supported RARI Chain from idea, to testnet, and now to mainnet. We're excited to continue working closely with the team to ensure their chain is supported and well-positioned to succeed.
