1. 获取 mint NFT 所需的 SnowCoin

rooch move run --function 0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe::coin::faucet

执行成功后查询余额。

curl --location 'https://dev-seed.rooch.network:443' --header 'Content-Type: application/json' --data '{
 "id":101,
 "jsonrpc":"2.0",
 "method":"rooch_getBalance",
 "params":["0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe", "0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe::coin::SnowCoin"]
}' | jq

可以看到目前余额为 10000，成功获取到了 SnowCoin。

{
  "jsonrpc": "2.0",
  "result": {
    "coin_type": "0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe::coin::SnowCoin",
    "name": "Snow Coin",
    "symbol": "SNW",
    "decimals": 10,
    "supply": "210000000000",
    "balance": "10000"
  },
  "id": 101
}

2. 创建 Collection

rooch move run --function 0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe::collection::create_collection_entry

观察输出中出现了 CreateCollectionEvent，说明创建 Collection 成功。

{
  "event_id": {
    "event_handle_id": "0x1353995413e39b6f04528b645355c944c661a5cce376d310f062fa37eae87920",
    "event_seq": "0"
  },
  "event_type": "0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe::collection::CreateCollectionEvent",
  "event_data": "0x01175fccfc454a288ea37f54fa00dd79e8bad13f2de5cfeb24d9787bb0ca0ebeef13536e6f77204e465420436f6c6c656374696f6ef6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe0140420f00000000001b5468697320697320536e6f77204e465420436f6c6c656374696f6e",
  "event_index": "2",
  "decoded_event_data": null
}

使用 event_id 查询 Collection 的 ObjectId

curl --location --request POST 'https://dev-seed.rooch.network:443' --header 'Content-Type: application/json' --data-raw '{
"id":101,
"jsonrpc":"2.0",
"method":"rooch_getEventsByEventHandle", "params":["0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe::collection::CreateCollectionEvent", null, "1000", false, {"decode":true}]
}' | jq

可以得到 Collection ObjectId 为 0x175fccfc454a288ea37f54fa00dd79e8bad13f2de5cfeb24d9787bb0ca0ebeef。

      }
    ],
    "next_cursor": "0",
    "has_next_page": false
  },
  "id": 101
}

3. mint NFT

使用第一步得到的 Collection ObjectId mint NFT：

rooch move run --function default::nft::mint_entry --args object_id:0x175fccfc454a288ea37f54fa00dd79e8bad13f2de5cfeb24d9787bb0ca0ebeef --args String:'Snow NFT 0001'

观察输出中 status 为 executed，说明 mint NFT 成功。

"execution_info": {
    "tx_hash": "0x78ad49e4979bd4a4183264dbcff2e6043dd26aa4d6775f848ce60be23935f7ca",
    "state_root": "0x42a1309909a1643f5f246908ac05d5d7084d723596302828faeea3c16a55139a",
    "event_root": "0x64f9a6ff1772dff2746e05e8c1a6e85a877c74b1955ecb16814c4247963daceb",
    "gas_used": "540399",
    "status": {
      "type": "executed"
    }
  }

4. 查询账号拥有的 NFT 信息

curl --location --request POST 'https://dev-seed.rooch.network:443' --header 'Content-Type: application/json' --data-raw '{
"id":101,
"jsonrpc":"2.0",
"method":"rooch_getObjectsByOwner", "params":["0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe", "0xf6c2242a258ac711845330715f44a975457a62f67587548d5835aba7ab9f3bfe::nft::NFT", null, "1000", false, {"decode":true}]
}' | jq

可以从输出中看到 NFT 的 name 为 Snow NFT 0001，这就是刚刚 mint 的 NFT。
