According to @alice_und_bob, their on-chain chat prototype now supports private DMs and will be publicly tested today at 4 pm UTC, with near-term ideas including posts on user profiles, linktree for profiles, Reddit/Hacker News-style forums, and curated news feeds (source: @alice_und_bob on X, Dec 27, 2025). The post highlights that advisors warned text on-chain is expensive, underscoring throughput and cost constraints that may shape feature rollout and usage limits for a SocialFi messaging app (source: @alice_und_bob on X, Dec 27, 2025). No token, chain, or monetization details were disclosed in the post, leaving direct trading exposure unspecified for now (source: @alice_und_bob on X, Dec 27, 2025). For traders tracking SocialFi adoption, the immediate catalysts from the post are the 4 pm UTC live test and any follow-on releases from the stated feature list (source: @alice_und_bob on X, Dec 27, 2025).
