List Property Step-by-Step test guide

Developer lists a property. Creates tokens, ensures deposit, validates input, stores listing, updates IDs, emits ObjectListed.

Pre-checks (polkadot.js):

1. Developer → Chain State

• Query marketplace → ongoingObjectListing

• Query marketplace → NextListingId .

• Query T::ListingDeposit constant.

• Validate region exists in regions → regionDetails(u16)

1. Check Charlie has free >= ListingDeposit and reserved == 0 (Accounts page).

Action (polkadot.js):

1. Developer → Extrinsics → pallet marketplace → listProperty

   • origin: Charlie (sign). This needs to be real estate developer.

   • region: 1 . This is the region where the object is located.

   • location: E1 7DB . This require to be the same as the location created in Regions pallet 2.5.1 Create Location . This is the location where the object is located.

   • token price: example 1_000_000_000 . The is the price of a single token.

   • token amount: 100 . The amount of tokens for an object.

   • data: 1 . The metadata of the nft.

   • tax paid by developer: Yes or No (choose)

   
2. Submit & sign.

Post-checks:

Developer → Chain State

• marketplace → listingDeposits . The screenshot is illustrative and may not reflect the exact state following the described attempts.

• marketplace → NextListingId incremented by 1. The screenshot is illustrative and may not reflect the exact state following the described attempts.

• marketplace → OngoingObjectListing exists and contains:

  • real_estate_developer == Charlie

  • token_price == value

  • token_amount == 100

  • listed_token_amount == 100

  • listing_expiry == current_block + listing_duration (query block number + constant)

  • collected_funds maps all accepted assets to 0

  

The expanded result from screenshot above:
