Caldera officially launched the ERA token with Arbitrum. This provides users with a new native way to trade assets on Uniswap’s single platform, one of the most extensive Layer 2 infrastructures. This launch introduces new liquidity and greater accessibility, and is a major step forward in Caldera’s intention to drive a network of related rollups.
Congratulations to @Calderaxyz on launching their on-chain expansion program!
By launching on Arbitrum One, users now get native ERA access with instant deep liquidity https://t.co/ezsXRkJ1YP

Arbitrum has verified the integration. This is another entry point into the growing Arbitrum ecosystem.
ERA expands into Arbitrum’s growing network
The presence of ERA on Arbitrum will expose the token to more users who already rely on the network to enjoy unparalleled payment speeds and cost savings.
New users will no longer have to go through numerous networks to buy and sell ERA, reducing friction. This growth is also aimed at powering Caldera’s single cross-chain environment, Metallayer. By registering ERA within the Arbitrum ecosystem, Caldera paves the way for more applications in alternatives, subject to cross-chain execution.
How ERA powers Metallayer
All dedicated blockchains in the Caldera system are linked through the backbone of the metalayer, ERA (the name of the infrastructure).
Tokens act as gas for operations that transfer information and liquidity between chains, allowing users to pay for bridges, messages, and other interactions that require coordination between chains.
In addition to its utility, ERA provides holders with a say in the future of Metallayer.
Token holders can vote on changes, lead the progression of upgrades, and help define how the Internet of Chains will evolve in the future.
The platform plans to launch staking in the near future, allowing users to verify cross-chain messages and receive incentives for network safety. This provides additional utility that increases as usage of the platform rollup increases.
Partnership benefits for users and developers
When it comes to Arbitrum integration, there are clear benefits for the entire ecosystem.
Caldera has direct access to one of the largest layer 2 networks, giving ERA tokens higher trading volumes and a wider range of users. Caldera rollup applications now have access to Arbitrum’s liquidity environment, making the onboarding experience easier for developers.
Cross-chain interactions are facilitated and Metallayer enables common liquidity within linked chains.
Arbitrum’s low fees and high speeds make ERA transactions cheaper and more accessible to users. The more Metallayer activity increases, the more important the efficiencies gained from this integration become.
Strategic reserves continue to support growth
In addition to the rollout, Caldera highlighted corporate partnerships, the protocol’s capabilities, and the contribution of the strategic reserve that reserves ERA for liquidity operations.
Reserves also have a no-sale policy and value is always returned to network tokens. It is a structure that provides long-term stability as more people adopt it.
Turning various revenue streams into ERA means that the Reserve aligns the incentives of developers, partners, and token holders across the ecosystem.
The launch of ERA on Arbitrum is a move towards Caldera’s larger vision: a network of rollups glued together with an effective interoperability layer.
Metallayer’s involvement in the larger blockchain ecosystem looks set to grow as more chains and applications join the system.
