It’s already connecting over 60 custom rollups across Optimism, Arbitrum, zkSync, Polygon, and even SolanaVM.
With more than 100 chains, 30 live mainnets, and $400M+ in total value locked, Caldera is supporting about a quarter of all Ethereum rollups. That’s some serious scale.
What makes it stand out? Its Metalayer protocol allows for instant cross-chain transactions and shared liquidity — without taking away the independence of each rollup.
Whether it’s Optimistic or ZK rollups, Caldera’s modular setup makes it easy to build and connect. Developers can plug in whatever they need while staying fully interoperable with the broader ecosystem.
At the core of it all is the ERA token — used for cross-chain gas, staking rewards, and governance. It gives both users and developers real ownership in the network.
Caldera isn’t just linking chains — it’s bringing the entire Layer 2 space together.
