《$ERA : Cross-Chain Liquidity Settlement Currency》
Caldera Metalayer not only facilitates Rollup communication, but it also provides a unified settlement mechanism for cross-rollup liquidity. Every Rollup-to-Rollup transfer operation ultimately returns to the ERA level for settlement.
Imagine a future where 500 Rollups are running in parallel, with all resource coordination, state synchronization, and asset bridging settled through ERA. This is the reality that makes ERA the foundational currency for 'inter-chain transactions'.
Estimating a current range of $3 is reasonable.
ERA may become the 'local currency' of the inter-chain collaborative economy.
