The rollup ecosystem is boomingābut itās also a patchwork of isolated chains. Caldera is stitching them together into a single, high-speed fabric. At the heart of this transformation? The ERA tokenāthe fuel for a new age of cross-chain collaboration.
Calderaās Metalayer is more than just infrastructureāitās the connective tissue between Layer-2 giants like Arbitrum, Optimism, and zkSync. Using Hyperlaneās ultra-fast messaging and intent engines, it breaks down the long-standing fragmentation problem, making cross-rollup actionsālike asset transfers or dApp callsāas seamless as sending a text.
But Caldera isnāt stopping at connectivity. Through its Rollup-as-a-Service (RaaS) platform, developers can launch custom rollups in record time, complete with Blockscout explorers, NodeOps hosting, and ready-to-go integrations. This isnāt theoryāmajor projects like Manta and Kinto are already on board, contributing to a TVL surpassing $550M and trading volume hitting $800M.
The ERA token (1B total supply) drives every layer of this ecosystem:
Staking for validator participation
Metalayer fee payments for cross-chain transactions
Governance rights to shape future upgrades
In July 2025, ERA debuted on Binance and Gate, instantly attracting over $39M in trading volume, putting it squarely in the spotlight of both DeFi builders and investors.
Adding to its ecosystem stickiness, Caldera offers .era domainsāENS-powered, EVM-compatible identities that make your Web3 presence portable across chains. Soon, Caldera will supercharge its oracle layer by integrating API3ās OEV Network, unlocking real-time, value-capturing data feeds for rollups.
Caldera isnāt just building another blockchaināitās weaving the Internet of Rollups, with ERA as the thread binding Web3 into a truly scalable, interconnected network.
