Watch Solana Actions and Blinks demo on YouTube.

Solana Actions are APIs to deliver signable transactions from a variety of web contexts. Blockchain links, or Blinks, are client applications that introspect Action APIs and construct user interfaces to interact with Actions.

As of July 2025, the Phantom Extension supports rendering Blinks on Twitter/X.com. If an Action URL is posted to Twitter/X.com, the Phantom extension is can construct a UI to interact with the transaction from directly within the user’s timeline.

This feature is disabled by default. Users can opt-in to enabling this feature via by goint to Settings > Experimental Features and turning on Blinks. Phantom will only render Actions that are registered under the Dialect-maintained Actions Registry.
