What is Caldera?
Caldera (ERA) ist eine Rollups-as-a-Service-Plattform, mit der Teams eigene, anwendungsspezifische Blockchains, sogenannte Rollups, starten können, die auf Ethereum abgewickelt werden. Sie besteht aus zwei Kernteilen: der Rollup Engine zum Bereitstellen anpassbarer Layer-2-Chains und dem Metalayer, der diese Chains verbindet, sodass Assets und Nachrichten zwischen ihnen bewegt werden können. Caldera unterstützt mehrere Frameworks, darunter Arbitrum Nitro und Optimism Bedrock für optimistische Rollups sowie zkSyncs ZK Stack und Polygon CDK für Zero-Knowledge-Rollups. ERA ist der native Token der Plattform. Er wurde im Juli 2025 eingeführt und wird für Gas-Zahlungen im gesamten Metalayer, für Staking durch Validatoren, die das Cross-Chain-Messaging absichern, sowie für Governance-Abstimmungen genutzt. ERA ist auf Ethereum bereitgestellt und mittlerweile auch auf Arbitrum One und Base aktiv. Als Token aus dem Jahr 2025, gebunden an eine sich weiterentwickelnde Infrastruktur, ist ERA ein neuerer Vermögenswert mit einer kürzeren Erfolgsbilanz als lang etablierte Netzwerke. Du kannst den Caldera-Preis verfolgen und ERA in einer Wallet in Selbstverwahrung halten.

That depends on what you want to do with your ERA. If you're holding only, any non-custodial wallet works. If you want to hold, swap across 20+ chains, connect to dApps, and use crypto for real-world spending, Zypto App is purpose-built for that while still being fully non-custodial.
