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 

Let me know if you’d like help with setting up wallets, configuring the SDK, or running this on testnets—happy to help!
