# Ocean Assets

Through this class we can publish assets & consume them to make 💲💲💲

### Creates URL Asset

* **create\_url\_asset**(`self`, `name: str`, `url: str`, `publisher_wallet`, `wait_for_aqua: bool = True` ) -> `tuple`

It is the most used functions in all the READMEs.

Creates asset of type "dataset", having `UrlFiles`, with good defaults.

It can be called after instantiating Ocean object.

**Parameters**

* `name` - name of the asset, `string`
* `url` - url that is stored in the asset, `string`
* `publisher_wallet` - wallet of the asset publisher/owner, `Brownie account`
* `wait_for_aqua` - boolean value which default is `True`, waiting for aquarius to fetch the asset takes additional time, but if you want to be sure that your asset is indexed, keep the default value.

**Returns**

`tuple`

A tuple which contains the data NFT, datatoken and the data asset.

### Creates Algorithm Asset

* **create\_algo\_asset**(`self`, `name: str`, `url: str`, `publisher_wallet`, `image: str = "oceanprotocol/algo_dockers"`, `tag: str = "python-branin"`, `checksum: str = "sha256:8221d20c1c16491d7d56b9657ea09082c0ee4a8ab1a6621fa720da58b09580e4"`, `wait_for_aqua: bool = True`) -> `tuple`:

Create asset of type "algorithm", having `UrlFiles`, with good defaults.

It can be called after instantiating Ocean object.

**Parameters**:

* `name` - name of the asset, `string`
* `url` - url that is stored in the asset, `string`
* `publisher_wallet` - wallet of the asset publisher/owner, `Brownie account`
* `image` - docker image of that algorithm, `string`
* `tag` - docker tag for that algorithm image, `string`
* `checksum` - docker checksum for algorithm's image, `string`
* `wait_for_aqua` - boolean value which default is `True`, waiting for aquarius to fetch the asset takes additional time, but if you want to be sure that your asset is indexed, keep the default value.

**Returns**

`tuple`

A tuple which contains the algorithm NFT, algorithm datatoken and the algorithm asset.

### Creates Arweave Asset

* **create\_arweave\_asset**(`self`, `name: str`, `transaction_id: str`, `publisher_wallet`, `wait_for_aqua: bool = True`) -> `tuple`

Creates asset of type "data", having `ArweaveFile`, with good defaults.

It can be called after instantiating Ocean object.

**Parameters**

* `name` - name of the asset, `string`

* `publisher_wallet` - wallet of the asset publisher/owner, `Brownie account`
* `wait_for_aqua` - boolean value which default is `True`, waiting for aquarius to fetch the asset takes additional time, but if you want to be sure that your asset is indexed, keep the default value.

**Returns**

`tuple`

A tuple which contains the data NFT, datatoken and the data asset.
