# (Legacy) XY Finance Widget (iframe)
XY Finance team has been wracking our brains just to come up with a powerful engagement tool to help strengthen your user retention, making them want to come back more for a satisfying user experience that this widget provides for your website and reducing friction by letting them fast-forward into your app's/site's key functionality. Note that this Widget will be constantly renewed as we're also gathering more resources and collecting feedback from users along the way.
The "Get Started" section below gives a step-by-step walkthrough as to how you're supposed to do to complete the embedding process and personalize your web/app experience, making transactions on your protocol way easier and interfaces look gracefully effortless! The "Configuration" section, however, categorizes the elements (keys) in the code, providing a clearer picture with regard to the website embedded.
