Frequently asked questions

Here are some common questions about Caldera.

How do I create a Caldera chain?

You can permissionlessly create a testnet Caldera chain via our public dashboard. If you'd like to run a Caldera chain in production, contact us.

Do I need an engineering team to run a Caldera chain?

No, one of the main benefits of Caldera is that you do not need in-house protocol engineers or site reliability engineers to run your blockchain. Caldera handles all of this, following standard best-practices to ensure reliability and security.

Who hosts the infrastructure for Caldera chains?

By default, we host all of the infrastructure for Caldera chains, including both the blockchain nodes themselves and auxiliary infrastructure (indexers, block explorers, etc.). However, interested teams can opt to self-host certain parts of the infrastructure if so desired.

Do I need to find validators for my chain?

No, Caldera will act as the validator/sequencer for the blockchain. Due to Caldera's architecture as a layer-two blockchain, Caldera chains are able to inherit security from a base layer blockchain, such as Ethereum or Polygon.

Can I transfer funds between my Caldera chain and other blockchains?

Yes! By default, Caldera chains come with a trustless bridge to the base settlement layer (eg. Ethereum or Polygon). Bridges to additional chains can be set up upon request.

What assets can be bridged?

Native tokens (eg. ETH or MATIC), ERC20 tokens (eg. USDC), and ERC721 NFTs can all be bridged.

What tokens can be used for gas fees on my Caldera chain?

As the creator of a Caldera chain, you can designate any blockchain native token (eg. ETH or MATIC) or any ERC20 token to be used as the gas-paying token.
