Frequently asked questions

What is a barter chain?

It's an exchange among 3–5 participants in a loop: you give your item to one person and receive what you want from another. The neural network finds such chains automatically.

How much does an exchange cost?

The exchange itself is free. The platform charges a small guarantor fee for facilitating and insuring the deal; a premium subscription expands your limits.

How is my data protected?

Personal data of Russian citizens is stored in Russia (Federal Law 152-FZ). Your exact delivery address is visible only to the counterparty in a confirmed deal.

What if a partner doesn't ship the item?

The guarantor pauses the chain, opens a dispute, and applies penalties. For long chains, an insurance deposit may be required.
