Fallbacks

A fallback is your safety net for when a blink fails to load or display as intended. 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.

Scaffolds​

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.

Pros​

  • Full control over customization (e.g. fallback images)
  • Shorter URLs
  • Tailored development experience

Cons​

  • Requires little setup
  • Requires own hosting (checkout vercel for free options)

Interstitials​

Don’t want to build from a scaffold? You can use our dial.to website as an interstitial instead. This approach provides the same core functionality (displaying your blink reliably) but with trade-offs: You can’t set custom fallback images for social previews, and the URL gets lengthy.

To implement it, prepend the interstitial link to your blink endpoint like this:

<INTERSTITIAL_LINK>/?action=solana-action:<LINK_TO_YOUR_BLINK_PROVIDER>

For example, here’s a Jupiter swap blink from USDC to SOL:

https://dial.to/?action=solana-action%3Ahttps%3A%2F%2Fjupiter.dial.to%2Fswap%2FUSDC-SOL

Note: Always URL-encode your link after the solana-action: parameter to avoid breakage. You can test this by pasting the full URL into a browser to confirm it resolves correctly.

Pros​

  • No setup
  • No hosting

Cons​

  • Longer URLs,
  • no custom image control,
  • less branding flexibility.
