Expanding ERA Across the Onchain Economy
Today, we’re launching the Caldera Onchain Expansion Program—our long-term initiative to bring the $ERA token to more networks, more liquidity venues, and more users across the onchain world. This program is designed to make ERA one of the most widely accessible, deeply integrated across the blockchain ecosystem.
And we’re starting with Arbitrum One, the top Ethereum L2 by total value secured.
ERA Is Now Live on Arbitrum One
As the first step in the expansion program, the ERA token is now natively available on one of the most active ecosystems in crypto: Arbitrum. The canonical ERA token is deployed at Arbitrum contract address 0x00312400303d02c323295f6e8b7309bc30fb6bce.
To support this launch, a liquidity pool has been seeded on Uniswap on Arbitrum One. Users can now trade between ERA and USDC, USDT, and ETH on Arbitrum.
This pool provides deep, permissionless liquidity from day one, allowing users to trade ERA seamlessly where they already spend their time onchain. Additionally, user-facing applications such as wallets and bridge aggregators can integrate ERA on Arbitrum.
Powered by Caldera Metalayer: Near-Instant Bridging, Unified Liquidity
What makes this expansion possible is the Caldera Metalayer, our unified multichain infrastructure that abstracts away the fragmentation typical of bridging and token deployments.
With the Metalayer:
Bridging ERA takes seconds
Users get a consistent, canonical ERA asset across supported chains
Liquidity can flow smoothly between ecosystems
Applications can compose across chains without fragmentation
The Metalayer is the connective tissue enabling the future we’ve always envisioned: scalable, specialized chains that remain unified at the asset and liquidity layer.
You can bridge ERA via the Metalayer at bridge.caldera.xyz.
Why the Onchain Expansion Program Matters
The program is designed around three core goals:
1. Universal Access
ERA should be available wherever developers build and users transact. Supporting more chains means reducing friction and enabling broader utility.
2. Liquidity Everywhere
By intentionally expanding liquidity across top L2s and eventually L3s, we strengthen the foundation for the entire Caldera ecosystem — including ecosystem chains, applications, and the Metalayer itself.
3. Deep Integrations
Multichain deployment isn’t just about token presence — it’s about embedding ERA into the workflows, incentives, and infrastructure of the ecosystems where modern applications live.
ERA’s onchain footprint will continue to grow in phases, each adding new venues and new capabilities.
What’s Coming Next
The Arbitrum launch is just the beginning.
Over the coming months, the Onchain Expansion Program will introduce:
Additional ERA deployments across major execution environments
Deeper liquidity programs and cross-chain market-making support
Expanded integrations with Caldera ecosystem chains
More venues powered by instant Metalayer bridging
This is the foundation for a broader, more interoperable, more scalable Caldera universe.
About Caldera
Caldera is powering the next internet. Its architecture consists of two core components: the Rollup Engine and the Metalayer. The Rollup Engine is a modular operating system used to launch high-performance, custom chains on leading chains and frameworks like Arbitrum, Optimism, and Base. The Metalayer then automatically connects every chain into one network. Through this interoperability protocol, all chains access shared liquidity and secure, intent-based bridging that transforms fragmented networks into a unified Internet of Chains.
