By hosting a simple website with Dialect’s blink client, you guarantee that users can still view and interact with your blink. This step is crucial for maintaining a seamless experience and preventing frustration.
The recommended way to create this fallback website is by using our scaffolds. These are ready-to-go

To implement it, prepend the interstitial link to your blink endpoint like this:
For example, here’s a Jupiter swap blink from USDC to SOL:

The recommended way to create this fallback website is by using our scaffolds. These are ready-to-go NextJS projects, pre-loaded with all the required configurations and dependencies.
With scaffolds, you can skip the tedious setup and jump straight into coding.
