Build an app for the user to enable cross-chain transfer of tokens in as many chains as possible using a simple UI. User should be able to track these transfers all from the same place, and should be notified of their status.
Cross-chain bridges also address the following:

• Lower gas costs with increased transaction speeds;
• User assets can be freely interacted with for a high user experience;
• Improved productivity and usefulness of existing crypto assets;
• Higher security and better privacy.
