In the context of Ethereum and many current blockchains facing high transaction fees, limited processing speeds, and suboptimal user experiences, Caldera emerges as a breakthrough solution. This is a blockchain infrastructure protocol specifically providing high-performance Layer 2 (L2) and Layer 3 (L3) rollups that can be deeply customized to meet the needs of each project.

1. What is Caldera?

Caldera is a Blockchain Infrastructure Protocol platform that allows for the rapid deployment of customizable L2 and L3 networks, optimized for dApps (decentralized applications) with:

  • High throughput

  • Low latency

  • Low transaction costs

As a result, projects can build their own powerful and cost-effective blockchains without the need for complex technical teams.

2. Rollup-as-a-Service (RaaS)

The highlight of Caldera is the Rollup-as-a-Service model, allowing developers to launch rollups in just a few minutes through leading frameworks such as:

  • Arbitrum Orbit

  • OP Stack

  • ZK Stack

This service helps projects:

  • Save development time

  • No need to maintain a team of specialized blockchain engineers

  • Can customize security, fees, and features according to specific needs

3. Metalayer – Instant cross-chain connectivity technology

Caldera develops Metalayer – a special connectivity layer that allows rollups to communicate directly and almost instantly without the need for traditional bridges.

  • Supports 100+ interconnected rollups

  • Transactions, asset transfers, data sharing in seconds

  • Reduce security risks from using cross-chain bridges

This opens up an era of seamless interaction between L2/L3 networks.

4. The power of the Caldera ecosystem

As of 2025, Caldera has achieved many remarkable milestones:

  • Operates 30+ blockchains on mainnet

  • Accounts for ~25% of the entire Ethereum L2/L3 ecosystem

  • TVL (total value locked) surpasses 600 million USD

  • 370 million transactions processed

  • 10+ million unique user wallets

Many prominent projects have used Caldera to deploy their own blockchains such as Manta, B3, Kinto, ApeChain, Bluwhale.

5. Backing from major investment funds

Caldera has successfully raised 24 million USD from notable investors:

  • Sequoia Capital

  • Founders Fund

  • Dragonfly Capital

This backing not only provides strong financial resources but also affirms Caldera's long-term growth potential.

6. ERA Coin – The heart of the ecosystem

ERA is the native token of the Caldera network, expected to launch soon.

The main applications of ERA include:

  • Pay transaction fees

  • Incentive rewards for nodes maintaining the network

  • Participate in governance

  • Support the development of dApps and utilities within the ecosystem

Basic information:

  • Total supply: 1 billion ERA

  • Distribution mechanism: aimed at long-term value and decentralizing the network

7. The future of Caldera and ERA

With an advanced technical platform, an optimized RaaS model, a quality project community, and support from leading investment funds, Caldera has the potential to become a pillar in L2/L3 infrastructure. The ERA coin, when launched, will serve as the lifeblood of the entire ecosystem, promoting decentralization, increasing liquidity, and expanding the user network.

Conclusion

Caldera is not just a simple blockchain scaling solution, but also a comprehensive infrastructure ecosystem that helps projects easily own powerful, cost-effective, and secure blockchains. With the ERA coin, projects will take a big step towards decentralization and sustainable growth in the Web3 era.
