Trading on the marketplace

• Verify your COSMO account (chapter 7).
• Read How it works and tick that you agree to the rules; it's needed once.
• Browsing is open to everyone, no account needed.

• List what you have: New listing picks copies straight from your wallet. Sell for a price, look for objekts to buy, or swap.
• Offer: on someone's listing, choose what you want and what you give (objekts, money or both). They can accept or send a counter-offer.
• Agree: an accepted offer locks the trade and opens a trade room with a chat and a checklist; the site suggests who goes first.
• Send the objekts in COSMO. The site sees them arrive on the blockchain and ticks them off; payments you tick yourselves.
• Rate each other when it's done. Ratings build your trust score.

Group orders let a GOM (group order manager) gather people for albums, physical objekts or merch: you sign up for slots and pay the GOM. You can also gift objekts; the site follows the delivery and the receiver confirms it was free.

• Don't send first to someone without ratings unless you're comfortable with it; the trade room says who should go first.
• Keep the conversation in the trade room, so moderators can help if something goes wrong.
• Use Report on a listing or trade, or write to the team from your Account page.
