What People are Saying

Working with Caldera has saved us the equivalent of two full-time engineers who would otherwise be solely focused on blockchain infrastructure.

Kevin Zhang

Co-founder, Curio

Very excited to see what gets built by teams like @Calderaxyz  who are leveraging this integration to deliver OP Stack rollups that use Celestia DA under the hood.

Nick White

COO, Celestia

Crypto is in nuclear winter but as shocking as this may be to some, there are still exceptional builders hacking away, with as much conviction as ever

The @Calderaxyz team are some of them.

Shaun Maguire

General Partner, Sequoia Capital

Scalability and usability are two of the most important issues in the industry, and the only way to solve these is by escaping the competition for blockspace.

Caldera opens up this limitless frontier with rapid and simple app-chains, permitting a manifold of crypto utility.

Ani Pai

Partner, Dragonfly

We're partnering with @Calderaxyz to power our OP stack app chain 🌋

We wanted a reliable, feature rich, and flexible rollup platform to take our app chain to the next level Caldera does exactly that so we couldn't be more happy about this partnership.

UniDex Exchange

DeFi meta-aggregator

With @Calderaxyz, building your web3 application is a breeze. One-click app-rollup deployment that's production-ready and running on mainnet - it’s seriously impressive.
