📝 WalkthroughWalkthroughThe extension now supports Nostr Like and Zap actions on YouTube as well as X/Twitter. It adds YouTube URL and npub validation, generalized relay filters, shared component injection, YouTube DOM hydration, compact Zap rendering, and host relay transport integration. ChangesYouTube Nostr action flow
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The extension can expose a YouTube Zap for an npub found in arbitrary video metadata or descriptions, potentially directing funds to an identity the channel did not declare, and host-transport profile responses may lack fields needed for correct rendering. These are concrete payment-safety and correctness issues, so the PR is not ready to merge until they are fixed. Possibly related PRs

Limit recipient discovery to creator-owned profile content.
Lines 34-40 scan video metadata and video descriptions. A video description can contain any checksum-valid npub. The extension can then show a Zap action that sends funds to an identity not declared by the channel owner.
Resolve an explicit creator profile surface, or verify that the declared npub belongs to the current channel, before setting data-recipient-npub. Do not use video metadata or video descriptions as recipient declarations.

isValidNpub accepts uppercase npubs in both the source and the generated bundle. The casing check allows an all-uppercase NPUB1... value, which passes the bech32 checksum but is not the canonical form that nip19.decode accepts.

@nostr-dev-kit/ndk 2.10 profileFromEvent display_name mapping NDKUserProfile
💡 Result:
In the @nostr-dev-kit/ndk library, the profileFromEvent function is responsible for parsing Nostr kind 0 (Metadata) events and mapping them into the NDKUserProfile object [1][2]. Regarding the display_name mapping: 1. Mapping Logic: When profileFromEvent processes a profile event, it maps the JSON key display_name found in the event's content to the displayName property of the NDKUserProfile interface [1][2]. 2. Implementation Detail: The internal logic explicitly handles this mapping as follows [1]: switch (key) { case "display_name": profile.displayName = payload.display_name as string; break; //... other cases } 3. Interface Definition: The NDKUserProfile interface defines displayName (camelCase) as a property [1][3][2]. This structure is used consistently throughout the library to store and access profile metadata, including in React hooks and internal caching mechanisms [4][5][6]. While the raw Nostr metadata (NIP-01) typically uses the display_name (snake_case) key, NDK translates this to the camelCase displayName property for use within your application code [1][7]. If you are working with the library, you should access the display name of a user profile via the displayName field of the NDKUserProfile object [5].

🌐 Web query:
site:github.com/nostr-dev-kit/ndk "function profileFromEvent" "image" "displayName"
💡 Result:
The function profileFromEvent is a utility found in the Nostr Development Kit (NDK) library, specifically within the user profile management module [1]. Its purpose is to parse a Nostr kind 0 event (which contains user metadata) and transform it into a structured NDKUserProfile object [1]. Regarding the specific fields you mentioned: - displayName: The function maps the display_name property found in the raw event JSON content to the displayName field in the NDKUserProfile object [1]. - image: The function handles both image and picture keys from the event content, assigning the value to both the picture and image fields of the NDKUserProfile object (noting that image is marked as deprecated in favor of picture in this library) [1]. In summary, the function takes an NDKEvent as input, parses its JSON content, and maps various profile metadata fields—including display name and image/picture—into a consistent format for use within an application [1].

site:github.com/nostr-dev-kit/ndk/blob v2.10.0 profileFromEvent export @nostr-dev-kit/ndk``
💡 Result:
In the @nostr-dev-kit/ndk library, profileFromEvent is a utility function exported from the core package [1][2]. It is used to parse a Nostr NIP-01 kind:0 (metadata) event and convert it into a structured NDKUserProfile object [1]. You can import it directly from the main package: import { profileFromEvent } from '@nostr-dev-kit/ndk'; The function accepts an NDKEvent object, attempts to JSON-parse the event content, and maps various profile fields (such as name, display_name, picture, banner, bio, nip05, lud06, lud16, and website) into a standardized NDKUserProfile interface [1]. It also assigns the event creation time and includes a serialized version of the raw event in the profile object [1]. This function is commonly used internally by NDK when fetching user profiles (e.g., in user.fetchProfile) [2] or when processing cache data [3]. As of version 2.10.0 and beyond, it remains a standard exported utility for handling metadata event parsing [1].

JSON.parse preserves display_name and picture but does not populate NDK fields such as displayName and image. Consumers read these mapped fields. Use profileFromEvent before returning the profile.

Summary
Why
The extension previously injected only the Like component on X. Its relay bridge rejected YouTube URLs and Zap profile/receipt filters, while direct component WebSockets can be blocked by host CSP. This adds host-specific placement and the narrowly validated relay operations needed by Zap without guessing YouTube-to-Nostr identity mappings.
