Base and Cross-Chain Interoperability As the blockchain ecosystem expands, interoperability becomes essential. No single network exists in isolation. Base contributes to a more connected ecosystem by maintaining compatibility with Ethereum standards while enabling bridges and cross-chain integrations that expand liquidity and user reach. Interoperability reduces silos. Users can move assets and data across networks, and developers can design applications that extend beyond a single chain. This connectivity strengthens the broader ecosystem and reduces fragmentation risk. • Maintains Ethereum-standard compatibility • Supports cross-chain integrations • Expands liquidity access • Reduces ecosystem silos • Enables multi-chain application design
