To implement a token of your own - you need to import SmartPy's FA2 template and in your own contract, rather than inheriting from `sp.Contract`, you'll inherit from the `FA2` contract.

```python
FA2 = sp.import_script_from_url("https://smartpy.io/dev/templates/FA2.py")
FA2 = sp.io.import_script_from_url("https://smartpy.io/dev/templates/FA2.py")
```

This line is similar to - `import FA2` in plain python.
But because we're writing SmartPy, the rules are different.
You need to use -
* `sp.import_script_from_url` - If you're not using SmartPy's online IDE.
* `sp.import_template` - If your code is running in the SmartPy online IDE. When you use this, you would be required to just pass in `"FA2.py"` as the argument and not the whole URL.
* `sp.io.import_script_from_url` - If you're not using SmartPy's online IDE.
* `sp.io.import_template` - If your code is running in the SmartPy online IDE. When you use this, you would be required to just pass in `"FA2.py"` as the argument and not the whole URL.

To access the `FA2` contract defined in the template, you need to use the dot(.) notation - `FA2.FA2`, where the first `FA2` represents the template as a whole and the second `FA2` represents the actual contract class defined in the template.

FA2 = sp.import_script_from_url("https://smartpy.io/dev/templates/FA2.py")

1. Import the FA2 template using and set it equal to `FA2`.
2. Define a smart contract - `Cyber_Token` that inherits from the core FA2 contract. (Use `Your_Token`) in the example above as a reference.
3. Initialize `Cyber_Token` with `single_asset=True`, `assume_consecutive_tokens=False`, address to the `admin`, and in the `metadata`, `name` needs to be equal to `"Cyber Token"`.
