Do you remember your experience during the last cross-chain operation? You might need to operate multiple wallets at the same time, switch back and forth between different interfaces, and constantly pay attention to whether you have enough fees. This experience feels more like participating in a competition that tests your mental capacity, endurance, and financial management skills, rather than a simple blockchain usage.

Ironically, such complex operations are happening in the Web3 field, which claims to be at the forefront of decentralized technology. The complexity of on-chain interactions has reached an incomprehensible level.

To address this issue, Caldera has proposed an innovative solution. It does not merely provide superficial improvements, such as changing the wallet interface or launching eye-catching airdrop events, but is committed to a thorough overhaul starting from the underlying architecture.

Caldera has introduced a mechanism called ERA, which is centered around integrating all fee operations on Rollups through a universal token. This means that in the future, users will no longer need to prepare multiple different tokens when conducting cross-chain asset transfers, trading, or cross-chain interactions; they will only need to hold ERA to operate smoothly within the entire Caldera ecosystem.

This innovation greatly simplifies user operations. You no longer need to prepare the corresponding tokens for each chain, nor do you have to busy yourself checking balances or exchanging currencies at the exchange before each interaction. On-chain operations will become as simple as daily tasks, no longer a "survival" experience.

Caldera's solution brings numerous practical benefits: it improves capital efficiency and avoids the fragmentation of funds; significantly enhances user experience and reduces participation barriers; while also providing convenience for decentralized application (dApp) developers, allowing them to no longer adapt to multiple fee models, thus speeding up the integration process.

It is worth noting that Caldera is not a standalone blockchain, but a complete ecosystem. Its emergence may signify a significant transformation in the way blockchain interacts, moving towards a more user-friendly and efficiency-oriented direction.
