@Caldera Official The Binance Caldera project is part of Binance’s 27th HODLer Airdrop campaign, featuring the ERA token. Launched on July 17, 2025, the campaign distributed 20 million ERA tokens to eligible BNB holders. Users who subscribed BNB to Simple Earn or On-Chain Yields between July 1 and 5 were included. Caldera is a Rollup-as-a-Service (RaaS) platform that allows developers to easily create custom rollups for Web3 applications. Its core components include the Rollup Engine and the Metalayer, enabling secure, scalable, and cross-chain communication. The ERA token powers the ecosystem through gas fees, staking, and governance, highlighting Caldera’s strong utility and growth potential.
