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.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.
