DGaming Marketplace

Init and run a node

Init node configuration with:

mpd init [node_name] --chain-id [chain_id] 

To specify maximum beneficiary fee init with flag 'max-commission'. Example:

mpd init node0 --chain-id mpchain --max-commission 0.07

To run a node with a script:

./run.sh
Additional parameters
-h, --help                show brief help
--demo                    set demo mode (add demo accounts)
-n, --num_account=n       specify number of demo accounts | 200 default
-m, --money=m             specify token amount for demo account | 100000token default
-s, --stake=s             specify stake amount for demo account | 100000000 default
-o, --output_file=o       specify output file | out.txt default
--embeded                 set embeded mode (for docker)

example:

$ ./run.sh --demo -n 5 -m 100token -s 200

This will start a node with two users, user1 and user2 (both are validators).

Client commands

To get information about account:

$ mpcli query account $(mpcli keys show [name] -a)

Example:

$ mpcli query account $(mpcli keys show user1 -a)

To mint an NFT for that user:

mpcli tx nft mint name $(uuidgen) $(mpcli keys show user1 -a) --from user1 

The token is not put on the market when minted.

To transfer a token from user1 to user2:

mpcli tx nft transfer cosmos16y2vaas25ea8n353tfve45rwvt4sx0gl627pzn $(mpcli keys show user1 -a) name 686769b1-9395-4821-8a9e-36008ad4ca7c --from user1

To put a token on market (to make it purchasable by anybody who offers the exact price you specified):

mpcli tx marketplace put_on_market 686769b1-9395-4821-8a9e-36008ad4ca7c 150token cosmos16y2vaas25ea8n353tfve45rwvt4sx0gl627pzn --from user1

Note that you must provide the beneficiary address.

To buy a token:

mpcli tx marketplace buy 686769b1-9395-4821-8a9e-36008ad4ca7c cosmos16y2vaas25ea8n353tfve45rwvt4sx0gl627pzn --from user2

To buy a token with specified commission add 'beneficiary-commission' (--beneficiary-commission or -c) flag

mpcli tx marketplace buy 686769b1-9395-4821-8a9e-36008ad4ca7c cosmos16y2vaas25ea8n353tfve45rwvt4sx0gl627pzn -c 0.013 --from user2

or

mpcli tx marketplace buy 686769b1-9395-4821-8a9e-36008ad4ca7c cosmos16y2vaas25ea8n353tfve45rwvt4sx0gl627pzn --beneficiary-commission 0.013 --from user2

To create some number of fungible tokens:

mpcli tx marketplace createFT fungible 1000 --from user1

To transfer some amount of fungible tokens:

mpcli tx marketplace transferFT $(mpcli keys show user1 -a) fungible 500  --from user1

Make an offer for an NFT that is not currently on sale:

mpcli tx marketplace offer TOKEN_ID 10token cosmos1j3zptzhjltjyrdn34vz0lvcwd86dl0nh86p65a --from user2

Accept the offer (offer ID can be found by running mpcli query nft TOKEN_ID):

mpcli tx marketplace accept_offer TOKEN_ID OFFER_ID cosmos1nglxddxs3w79fhv5j6ddtudkqn50zzg3p40kyw --from user1

Full scenario

After running ./run.sh, 4 users are created: user1 (minter and seller), user2 (buyer), sellerBeneficiary and buyerBeneficiary (each has 1000token coins in the beginning).

Mint a new token:

$ mpcli tx marketplace mint $(uuidgen) name description image token_uri --from user1

Output:

}

Change token params: Use 'update_params' with flags --image --price --description --token_uri --name

mpcli tx marketplace update_params 4eb281c9-1eea-4aab-b508-a3c27828b572 --from user1 -i newimage -p 500token -d newdescription -u newuri -n newname

List nfts:

$ mpcli query marketplace nfts

Output:
