Binance has officially launched Caldera ( $ERA ) as the 27th project in its BNB HODLer Airdrops. Users who subscribed their BNB to Simple Earn (Flexible and/or Locked) and/or On-Chain Yields products got the Airdrop for free.
As ERA is now live on Binance, Lets explore the project and see what its all about. We will also discuss how you can participate in future Hodler Airdrops.
What is Caldera?
Caldera is The Internet of Rollups, a platform that’s making crypto faster, cheaper, and more interconnected than ever before. For crypto users, Caldera means no more high fees, slow transactions, or fragmented ecosystems. By allowing for horizontal scaling across a limitless number of chains, Caldera is the endgame for blockchain performance. Caldera’s capacity will never be saturated, and Caldera chains can adapt to every new use case that emerges in the blockchain space.
Era Token utility
Utility will include the following:
Universal Cross-chain Gas: ERA will be used as the payment mechanism for cross-chain transaction relays
Network governance: ERA holders will be responsible for governing changes to the underlying protocol, including technical upgrades, fee mechanisms and DAO treasury spend
Staking: ERA tokens will be used to secure the network. In the future, ERA can be used as a staking token for sub-networks.
ERA will also be used as a social coordination tool to further unite rollups to bootstrap their networks to achieve success in their earliest stages
Caldera Existing Products
Caldera combines two products:
The rollup engine, enabling any amount of performant new chains to be created quickly
The metalayer, an all-purpose full-stack interoperability solution that makes it possible to interact across chains.
What is Metalayer?
it is designed to revolutionize how rollups interact with other chains, the Metalayer provides a seamless, secure, and efficient platform for cross-chain operations.
The Metalayer empowers developers and protocols to overcome the constraints of isolated blockchain ecosystems.
Launch Truly Interoperable Chains: Deploy new Caldera rollups with the Metalayer interoperability from day zero, or integrate the Metalayer into your existing Caldera chain to instantly connect to a broader ecosystem.
Build Sophisticated Cross-Chain dApps: Utilize the Metalayer’s Developer Toolkit to create applications that facilitate efficient communication and value transfer between rollups, regardless of their underlying stack.
Access Unified Liquidity: Tap into a growing network of shared liquidity, enabling more efficient markets and better user experiences for your applications.
Abstract Complexity: Focus on your core application logic and user experience, while the Metalayer handles the intricacies of cross-chain communication, optimal routing, and secure settlement.
Deploy Rollups
The Caldera Ecosystem also includes the Rollup Engine, cloud-based infrastructure that allows anyone to launch a customizable blockchain in minutes.
The Caldera Rollup engine now secures $1B+ in total value and has processed 550M+ transactions across 17M+ unique addresses. This growth underscores Caldera’s ability to handle real-world demand while maintaining reliability and efficiency.
Caldera targets the Ethereum rollup ecosystem, which is rapidly growing but highly fragmented.
Over 125 Layer 2s exist, with hundreds more around the corner, including ones for large institutions. Caldera’s solution will also eat into the general “enterprise blockchain” market, which has been valued as a several-billion dollar opportunity.
Caldera already powers ~25% of Ethereum rollups, with 100+ chains, 30 live mainnets, and over $400M in TVL.
Caldera’s metalayer will bring interoperability solutions into the mix, which is already a multi-billion dollar opportunity as evidenced by the growth of projects like LayerZero, Wormhole, and others.
Current metrics include:
Total unique wallets: 27.6M
Daily unique users (by IP/network usage): ~250k
Caldera Catalyst Campaign: 5+M MAUs
