Question 1

What is ERA?

Accepted Answer

ERA is the native utility token of the Caldera ecosystem, serving an interoperable architecture composed of Rollup Engine and Metalayer. Rollup Engine is a modular system for deploying high-performance custom chains across different base chains and frameworks; Metalayer automatically connects these chains into a network. ERA is not the general Gas token for an individual chain deployed through Rollup Engine. Its announced core roles are to provide an economic layer for cross-chain operations on Metalayer and to give holders on-chain governance influence over Metalayer protocol and ecosystem matters.

Question 2

What role does ERA play in cross-chain operations?

Accepted Answer

When a transaction initiates a cross-chain interaction on Metalayer, or when data needs to propagate between different chains, the related fees are denominated in ERA. In other words, the fees correspond to the step of allowing information and operations to cross otherwise separate chains and enter the interoperable network, rather than broadly replacing every chain’s own transaction fees. This unified denomination places the cost of multi-chain interconnection at the Metalayer layer: when a user or application initiates an operation requiring cross-chain processing, the network charges fees in ERA; if an operation does not involve cross-chain interaction or data propagation at this layer, it cannot be inferred that it necessarily incurs ERA fees.

Question 3

Why do validators stake ERA?

Accepted Answer

Validators stake ERA to provide security for Metalayer and validate cross-chain messages. The role of staking here is to connect the economic security backing validators’ participation in network security with their validation behavior, rather than merely creating passive returns independent of network work for token holders. Under the officially announced mechanism, a node’s participation and influence in the decentralized validation network are proportional to its stake size. Therefore, stake size affects a validator’s relative role in this security model; the objects being validated are cross-chain messages, with the goal of ensuring that cross-chain delivery does not rely solely on a single participant.

Question 4

What governance can ERA holders participate in?

Accepted Answer

ERA holders can propose and vote on Caldera Improvement Proposals (CIPs) through an on-chain process, thereby participating in major decisions concerning the Metalayer protocol and ecosystem. Governance subjects include protocol upgrades and funding for third-party developers and ecosystem participants, rather than direct voting on every day-to-day operation of each connected chain. Governance can also influence leadership arrangements for the foundation and specialized committees, such as electing members of subcommittees including a security committee. The inaugural security committee members were appointed by Caldera Foundation directors, which differs from subsequent governance arrangements involving community participation; the two must not be treated as the same completed election process.

Question 5

How does ERA unlock for the core team and early investors?

Accepted Answer

ERA allocated to the core team and early investors first undergoes a one-year cliff: before that full year ends, these tokens do not gradually unlock under this schedule. After the cliff ends, the remaining release period is 24 months of linear vesting. Linear vesting means these tokens are released continuously in installments over 24 months, rather than becoming fully available all at once on a single date. This rule applies only to the core-team and early-investor allocations explicitly identified here by the official announcement; it cannot be used to infer that other allocation categories follow the same schedule.

Question 6

How is ERA’s initial community allocation arranged?

Accepted Answer

The Caldera Foundation announced that 7.0% of ERA’s initial total supply was allocated as direct rewards to community and ecosystem members who contributed during Caldera’s development. This arrangement concerns the initial airdrop allocation and does not mean that all users or all token holders automatically receive the same proportion. The announcement required eligible individuals to register through the claim website before token launch, and placed the snapshot date, eligibility criteria, and claim steps in foundation documentation. Therefore, eligibility to receive this initial allocation depends on specific qualifications and completing registration, rather than merely holding or purchasing ERA afterward.

Question 7

What is the relationship between ERA and future specialized subnetworks?

Accepted Answer

Official materials state that the current validator-staking security model is also planned to extend in the future to specialized subnetworks, such as subnetworks for ZK proof generation. This describes a proposed direction for extending the same security model and does not mean that these specialized subnetworks have already all been enabled as existing features. Therefore, when understanding ERA’s uses, distinguish the announced Metalayer cross-chain fees, validation of cross-chain messages, and on-chain governance from plans for future specialized subnetworks. The former are the core uses listed in the announcement, while actual activation of the latter still depends on subsequent implementation.
