Besides exchanging crypto, you can use the escrow to pay for a product or a service: the buyer deposits crypto and the seller gets paid as they deliver.
Milestones
The work gets split into milestones. As each one is completed and approved, the corresponding part of the payment gets released. Ideal for services or deliveries in stages.
Anti-lockup protection
So nobody can leave the money stuck forever by refusing to confirm, there's a time limit: if a party doesn't respond, the state advances automatically to unblock the trade.
The platform fee applies to this type of trade. See Fees.
