Caldera and Marble

Caldera and Marble
Marble and Caldera partner to enable the next-level of performance and UX for blockchain applications.

We are thrilled to announce a partnership between Caldera and Marble Wallet! With Caldera, developers can build dedicated blockchains for their applications, leading to improved performance, UX, and lower fees for users.

Marble's mission is to enable developers to build the most user friendly and performant blockchain applications. We believe Caldera is one of the best ways to do so, and we are excited to commit to working with them in order to achieve this mission.

Starting today, Marble Wallet enables users to onboard into the Caldera ecosystem seamlessly by using our embedded and email-based self-custodial wallet. Regardless of whether they already have a Marble wallet or not, users can get started with Caldera applications in a matter of seconds, without worrying about downloading browser extensions, setting up RPC endpoints, or writing down seed phrases.

Caldera developers can also easily offer wallet onboarding, a fiat on-ramp, and pre-built UI components to their users via Marble Wallet. Similar to Caldera, developers will also be able to take advantage of Marble's APIs and SDK to fully customize the wallet experience.

By using Caldera chains, developers can control their entire technology stack, without compromising on the ability to bridge to and inherit security from popular blockchains like Ethereum and Polygon. This enables developers to leverage the liquidity and infrastructure native to existing chains while having control over what matters most to their applications.

Caldera chains are EVM-compatible, enable gas customization, and are interoperable with other EVM-based chains like Ethereum and Polygon. This translates into unprecedented performance, low and predictable fees, and revenue generation for applications.

How can I get started?
