🆕 B20 Asset tokens can post on-chain announcements (Announcement: id, description, uri) — issuer notices, corporate actions, redemptions — a channel ERC-20 has no equivalent for. Reads a token's announcement feed (active vs ended) from CDP-indexed events. The issuer-communications primitive for agents holding tokenized/RWA B20 assets.
