Caldera has officially launched its ERA token on Arbitrum, which offers users a new native way to trade the assets on a single platform in Uniswap on one of the most comprehensive Layer 2 infrastructures. The launch introduces new liquidity and further accessibility and takes a significant step forward in Caldera’s intention to power a network of associated rollups.
Congratulations @Calderaxyz on the launch of the Onchain expansion program!
Launching on Arbitrum One, users now get native ERA access with immediate deep liquidity https://t.co/ezsXRkJ1YP

Arbitrum verified the integration, which is a new entry into the expanding Arbitrum ecosystem.
ERA expands to Arbitrum’s growing network
ERA’s presence on Arbitrum will expose the token to more users who already rely on the network to enjoy unparalleled settlement speed and lower fees.
New users no longer have to go through a number of networks to buy and sell ERA, and this reduces friction. This growth will also aim to boost Metalayer, a single cross-chain environment from Caldera. With the deposition of ERA in the Arbitrum ecosystem, Caldera paves the way for more applications in alternatives, depending on the implementation across the chain.
How ERA powers the metalayer
All purpose-built blockchains in the Caldera system are connected via the ERA, the backbone of Metalayer, the name of the infrastructure.
The token serves as a gas for the operations that transfer information and liquidity between chains, allowing the user to pay for bridging, messaging and other interactions that require coordination between the chains.
In addition to utility, ERA offers its holders a voice in the future of Metalayer.
The token holders can vote on the changes, direct the progress of the upgrades, and help define the ways in which the Internet of Chains will evolve in the future.
The platform will launch staking in the near future, which can help users validate cross-chain messages and receive incentives for network security. This provides an additional utility that increases as the platform’s rollups are used.
Benefits of the partnership for users and developers
There are clear benefits for the ecosystems as a whole when it comes to Arbitrum integration.
Caldera has direct access to one of the highest volume Layer 2 networks, offering the ERA token greater trading volume and a wider range of users. The onboarding experience is easier for developers as Caldera combination applications now have access to Arbitrum’s liquidity environment.
Interactions between chains are made easier, enabling common liquidity in chains connected by Metalayer.
Arbitrum’s low costs and high speed also make ERA transactions cheaper and more accessible to users. The more Metalayer activity, the more important is the efficiency gained from this integration.
The strategic reserve continues to support growth
In addition to the rollout, Caldera highlighted the contribution of its Strategic Reserve, which ERA reserves due to corporate ties, protocol operations and liquidity operations.
Reserve is also a no-sell policy and the value is always returned to the network token. This is a structure that will ensure long-term stability as more people adopt it.
Converting various revenue sources into ERA means that the reserve will align the incentives of the developers, partners and token holders across the ecosystem.
The launch of ERA on Arbitrum is a step towards Caldera’s larger vision, a network of glued together rollups with an effective interoperability layer.
Metalayer’s involvement in the larger blockchain ecosystem appears to be expanding as more chains and applications join the system.
