### deployToken

⤿ Overridden Implementation(s): [STFactory.deployToken](https://github.com/PolymathNetwork/polymath-core/tree/096ba240a927c98e1f1a182d2efee7c4c4c1dfc5/docs/api/STFactory.md#deploytoken)

Deploys the token and adds default modules like permission manager and transfer manager. Future versions of the proxy can attach different modules or pass some other paramters.

```javascript
function deployToken(string _name, string _symbol, uint8 _decimals, string _tokenDetails, address _issuer, bool _divisible, address _treasuryWallet) external nonpayable
returns(tokenAddress address)
```

**Arguments**

| ---------------- | ------- | -------------------------------------------------------- |
| \_name           | string  | is the name of the Security token                        |

| \_decimals       | uint8   | is the number of decimals of the Security Token          |
| \_tokenDetails   | string  | is the off-chain data associated with the Security Token |
| \_issuer         | address | is the owner of the Security Token                       |
| \_divisible      | bool    | whether the token is divisible or not                    |
