Unique Marketplace Escrow

Glossary

• Quote - an ID of a currency used to pay for NFT tokens.
• Seller - a person who wants to sell a NFT token.
• Buyer - a person who wants to buy a NFT token.

How does the whole system works

Seller sends token to escrow admin and sets it's quote price. Escrow creates an offer. Buyer sends quote to Escrow. Escrow sends token to the Buyer and quote to the Seller. The Buyer and the Seller can get back what they sent.

What does it do

• For each NFT token sent to escrow admin it calls Matcher Contract's method registerNftDeposit to store real token's owner in blockchain.
• It calls Matcher Contract's method registerDeposit to store quote deposit after Kusama Escrow schedules quote income registration.
• On successful Matcher Contract's ask call it creates an offer for Marketplace Backend to show.
• On successful Matcher Contract's buy call it sends bought token to the buyer, schedules quote outcome for Kusama Escrow to handle and creates a trade for Marketplace Backend to show.
• On successful Matcher Contract's cancel call it sends NFT token back to seller and removes the offer.
• On successful Matcher Contract's withdraw schedules quote outcome back to buyer.
