What is Caldera?
Caldera (ERA) adalah platform rollups-as-a-service yang memungkinkan tim meluncurkan blockchain khusus aplikasi milik mereka sendiri, yang disebut rollup, dengan penyelesaian di Ethereum. Platform ini memiliki dua bagian inti: Rollup Engine untuk men-deploy chain Layer 2 yang dapat disesuaikan, dan Metalayer, yang menghubungkan chain-chain tersebut sehingga aset dan pesan dapat berpindah di antaranya. Caldera mendukung beberapa framework, termasuk Arbitrum Nitro dan Optimism Bedrock untuk optimistic rollup, serta ZK Stack milik zkSync dan Polygon CDK untuk zero-knowledge rollup. ERA adalah token native platform ini. Token ini diluncurkan pada Juli 2025 dan digunakan untuk pembayaran gas di seluruh Metalayer, staking oleh validator yang mengamankan pesan cross-chain, dan voting governance. ERA di-deploy di Ethereum dan juga telah aktif di Arbitrum One dan Base. Sebagai token 2025 yang terikat pada infrastruktur yang terus berkembang, ERA adalah aset yang lebih baru dengan rekam jejak lebih pendek dibanding jaringan yang sudah lama mapan. Anda dapat memantau harga Caldera dan menyimpan ERA di wallet self-custody.
