Deploying and testing

Deploying and testing the marketplace contract

The marketplace contract can be deployed without any parameters, as it's token-agnostic:

ccli deploy ./contracts/market.arl

To create a sale, the list_for_sale entrypoint is called as follows (replace with the correct values):

ccli set account alice
ccli call market --entry list_for_sale --arg '{"fa2_": "<TZOMBIES MARKET ADDRESS>", "token_id_": 1, "amount_": 1, "price_": 1000000, "expiry_": "2033-01-01 00:00:00"}'

Note that the price argument is expressed in mutez, one million-th of a tez. Hence, 1_000_000 utez equals 1 ꜩ.

Now let's switch the account and buy the NFT (this will fail):

ccli set account bob
ccli call market --entry buy --arg '{"order_id": 1, "amount_": 1}' --amount 1tz

Why did it fail? Remember, the marketplace contract is not allowed to transfer Alice's tokens. She need to first add the marketplace as an approved operator for her tokens. This can be done once for all her tokens with the following call:

ccli set account alice
ccli call tzombies --entry update_operators_for_all --arg '{"upl": [{ "kind": "left", "value": "<MARKET CONTRACT ADDRESS>" }]}'

Now, try to buy again, it should work!
