How It Works: Behind the Scenes
1. Initializing the SDK
You connect to Caldera’s Metalayer by specifying source and destination chains via CalderaClient.init(). The SDK handles cross-rollup bridging under the hood .
2. Intents Engine
Caldera’s intent engine enables declarative operations like tokenTransfer, abstracting cross-chain message formatting and routing details .
3. Settlement via Message Passing
The Metalayer relies on fast, secure messaging using Hyperlane protocols for cross-rollup communication and settlement .
⸻
Why Use It
• One‑click bridging – no need to manage low-level bridge contracts.
• Fast finality – near‑instant cross‑rollup transfers.
• Unified gas – uses $ERA for all cross‑chain relay fees  .
• Secure & audited – built in collaboration with top teams using Hyperlane and rigorous audits .

🧪 Next Steps
If you’re building on Caldera, consider exploring:
• Widget SDK for embedding bridge UI in your dapp 
• Sub‑nets & staking – how $ERA secures the network and enables governance 
• Multi‑VM support – deploy rollups with Optimistic, ZK, and Solana‑compatible VMs
