X Handle Methods

SNS supports the registration of Twitter handles, allowing users to connect their Twitter profile to their wallet as described in this section: X (formerly Twitter) TLD.

X (formerly Twitter) root TLD

const TWITTER_ROOT_PARENT_REGISTRY_KEY = new PublicKey(
  "4YcexoW3r78zz16J2aqmukBLRwGq6rAvWzJpkYAXqebv"
);

The .twitter TLD is owned by the root TLD and all twitter handles are subdomains of the .twitter TLD.
