A marketplace to tokenize and trade anyone's time as "time tokens." Its tagline: "'Second' is the ultimate currency…"

The collab

The first-ever third-party project built on Mint Club. Partner tx0x (a Korean blockchain dev firm, 10+ yrs, prior builder of the 9cscan explorer) built and independently operated the marketplace; Mint Club provided contract-level technical support. Time tokens were backed by the MINT collateral contract (one token per person). tx0x owned the project and ultimately shut it down.

What worked

Reached ~1.3M "seconds" of time assets generated on-platform (per the app's own counter). Its founding idea traces to InTime, which won 1st place at the Upbit hackathon in Oct 2019: a validated, award-winning concept before it became a Mint Club build.

What broke

Timing. Tokenizing and trading someone's time is an accepted idea today, but in 2021 it was too radical for the market. The concept arrived early. (It was also partner-owned, so the partner's decision to end it closed the book.)

What it seeded

The proof-of-concept that external teams could build standalone products on Mint Club, validating Mint Club as a platform/protocol, not just a first-party app. The conceptual ancestor of later partner builds (Farcards, Hamcaster).
