### Request

```js
neolineN3.getNetworks()
.then(result => {
    const {
        chainId,
        networks,
        defaultNetwork
    } = result;

    console.log('chainId: ' + chainId);
    // eg. 6

    console.log('Networks: ' + networks);
    // eg. ["MainNet", "TestNet", "N3TestNet"]

    console.log('Default network: ' + defaultNetwork);
    // eg. "N3TestNet"
})
.catch((error) => {
    const {type, description, data} = error;
    switch(type) {
        case 'NO_PROVIDER':

    }
});
```

### Response

```js
{
    chainId: 6,
    networks: ["MainNet", "TestNet", "N3TestNet"],
    defaultNetwork: "N3TestNet"
}
