Let's talk interoperability. There are two important, although sometimes competing, factors in the development of interoperability protocols: standardization and customization. Standardization provides a framework for better UX, simplifying the process of moving assets or messages across different chains, to feel like one unified experience. Customization gives builders more design space for innovation and the development of new cross-chain use cases. Teleporter, the native messaging protocol coming soon to Avalanche, will give developers the benefits of both standardized formats and endless customization ????
