I designed a warm-introduction marketplace around escrow, confirmation, and a published dispute rule.
A warm-introduction marketplace fails when one party says the introduction happened and the other says it did not.
The interface needed to explain when credits were locked, what confirmed delivery, and how a dispute would be resolved before either person committed. Trust depended on the transaction rule being visible, not on adding more feed activity.

The story is on the left. The decisions behind it are below.
The decisions that made it work
Dual party escrow
Credits lock when the intro is requested and release when the requester confirms it happened. Neither side can move the money alone.
A published dispute rule
Disputes default to a documented 75/25 split rather than a case by case judgement. Publishing the rule up front is what makes people willing to transact at all.
