How to Buy/Sell on Open Marketplace

Quick walkthrough of Buy-Sell flow on Particl Open Marketplace

If you’ve already installed the Particl Open Marketplace and have it enabled on your Particl Desktop client, then you’re all set and ready to start buying and selling stuff for crypto without giving away your data.

Complete Buy flow

If you haven’t installed or enabled the Particl Open Marketplace yet, then follow our Getting started with Particl Open Marketplace guide!

The following steps will show you how to use the Open Marketplace by going, in detail, through a complete purchase using the Open Marketplace.

At each step of the process, an encrypted P2P network called SMSG makes the secure transmission of data and messages between the buyer and the seller. It is on this network that any marketplace content (i.e. listing pictures, orders, etc) is stored.

SMSG messages are shared in a peer-to-peer way between all the nodes running the marketplace. Only the party you’re transacting with will be able to decrypt your messages, orders, and any other kind of information, and therefore be notified about orders and their updates.

Listing stage

The lists an item for sale

  1. To list an item, first go to the Sell page of Particl Desktop
  2. On the Sell page, you will see a list of all previously listed items. To add a new one, click on + Add new listing
  3. Fill the Listing’s details and add pictures. Note that the first picture you add is going to be used as the thumbnail for your Listing
  4. Click on Save & Publish and then type your encryption password to temporarily unlock your wallet. An unlocked wallet is required to publish Listings
  5. Choose the duration of the Listing and click on Confirm & Publish – e.g. if you choose 1 week, then your Listing is going to stay up on the Open Marketplace for 7 days
  6. Wait for at least one confirmation and your Listing will appear in the Listings page of the Particl Open Marketplace
Listing fees are calculated based on the duration and size of your Listing.
In other words, the longer it stays up, and the more images/text your Listing has, the more expensive listing the item will be.

Bidding stage

The places a bid on item

During this step, the Buyer is going to place a bid (an order) and “soft lock” twice the amount of the item being purchased (including shipping costs). Placing a bid will most probably use more than twice the value of the purchased item, but the extra funds will be refunded after ~30 minutes. To know why, checkout FAQ: Why is a big portion of my Anon balance getting locked after bidding on an item?

  1. Go to the Listings page
  2. Browse the Marketplace, and click on the item you want to purchase
  3. On the Listing’s pop-up page, verify the total amount required to fund the escrow and then add the item to your cart by clicking on Add to cart
  4. To checkout, click on the cart icon at the top right section of the Particl Desktop client or by going to the Buy page
  5. Verify the content of your cart, and click on Continue to shipping
  6. Fill your shipping information and, optionally, save your shipping profile for future purchases (this profile stays only on your computer)
  7. Verify all the information is correct on the next page, and then click on Place order to place your bid
  8. Confirm you want to place the order by clicking on Yes, place order on the pop-up confirmation page that appears
  9. You can now see the status of your order by clicking on the Orders tab of the Buy page

Order stage

The accepts/rejects Buyer’s bid

  • If the seller rejects the bid, the soft locked funds will release back to you and the Order will be cancelled
  • If the seller accepts the bid, the funds required for the escrow will soft lock on his side as well and the Buy flow continues
