FAQ Section
Q1: Why is interoperability critical for DeFi?
A1: Enables liquidity pooling across chains and reduces ecosystem fragmentation.
Q2: What risks do cross-chain bridges pose?
A2: Smart contract vulnerabilities and centralized custody points.
Q3: How does IBC differ from atomic swaps?
A3: IBC facilitates generalized messaging, while atomic swaps focus strictly on asset exchanges.
Future Outlook
