## Example Usage

### Input

Building cross-chain bridge for DeFi protocol connecting Ethereum and Arbitrum. Need bidirectional ERC-20 token transfers. Security is paramount - targeting $50M+ TVL. Want to minimize trust assumptions while maintaining reasonable UX (sub-30min transfers). Team: 4 developers, 6-month timeline, $200K security budget.

### Output

**Ethereum-Arbitrum DeFi Bridge Architecture**

**Mechanism Selection: Optimistic Bridge with Fraud Proofs**
