From Testnet to Mainnet: A Comprehensive Record of Caldera's Architectural Evolution

The architectural evolution of #Caldera ($ERA ) showcases its technological breakthroughs and ecological expansion from the early testnet to the mainnet rollout:

1. Testnet Phase (2023)

Initially centered on Optimistic Rollup, it supported developers to deploy customized L2 chains in 5 minutes, providing sub-second confirmations and free test tokens, attracting over 85,000 users for interaction. Game-like designs such as 'Break Caldera' validated high throughput capabilities, laying the foundation for multi-virtual machine compatibility (EVM/SolanaVM).

2. Technical Upgrade (2024)

Introduced a modular layered architecture, allowing developers to freely choose data availability layers (like Celestia, Ethereum mainnet) and settlement layers, reducing costs by 75%. The launch of the Metalayer protocol addressed liquidity fragmentation issues between Rollups, enabling seamless cross-chain asset flow.

3. Mainnet Explosion (2025) @Caldera Official

After the mainnet launch, Caldera has supported over 60 chains (like Manta Pacific, ApeChain), with TVL surpassing $800 million, becoming the first RaaS platform to simultaneously operate Optimism, Arbitrum, and ZK Rollup. Its 99.99% uptime SLA guarantee and dynamic expansion API further solidified enterprise-level reliability.

From testnet to mainnet, Caldera has redefined the expansion paradigm of the Rollup ecosystem with modular design and cross-chain interoperability, becoming a key player in Web3 infrastructure.
