post.tech

post.tech launched on Arbitrum in September 2023 as a SocialFi app that binds an X account to an onchain profile, letting users buy and sell shares of that profile in ETH at prices set by a bonding curve. Unlike its closest peers, it also turned individual posts into tradable assets and shared part of the trading fee with share holders rather than only with the profile owner.

Each trade carried a fee of roughly 10%, split between the platform and the profile owner, with holders receiving dividends proportional to their position. Buying a share also unlocked a group channel readable by every member, which pushed the product toward community rather than one-to-one access. Points settled per epoch and converted into POST; volume expanded quickly in launch week, with about USD 1.8 million, 87,000 transactions and 11,000 active wallets on 21 September 2023, before activity fell sharply through 2024.
