What is Caldera? ($ERA)
Caldera is a Rollup-as-a-Service (RaaS) platform launched in 2022, designed to help developers easily create and launch custom Layer 2 (L2) or Layer 3 (L3) blockchains on Ethereum — without dealing with the technical complexities of infrastructure.
It provides a wide range of development tools and supports several leading rollup frameworks, including Arbitrum Nitro, Optimism Bedrock, zkSync ZK Stack, and Polygon CDK. This flexibility lets developers choose the best tech stack to fit their specific needs — whether it’s for DeFi, gaming, NFTs, or dedicated appchains.
