# Mobile version provider

`Cyano` mobile is the `mobile provider`'s standardized open source implementation, and it follows the `CEP-1` proposal. The `PC` version of the `dAPI` has been extended to the mobile version, covering the three usage scenarios:

* Integrated the `dAPI-mobile` QR code scanning mechanism to login and invoke smart contracts
* Integrated `cyano-SDK` `dApp` wake call mechanism
* Integrated the `dAPI-mobile` embedded `dApp` login and smart contract invocation method mechanism

In the `cyano-mobile` app, the `dApp` data request `URL` follows the `CEP-1` standard:

```java
import android.net.Uri;
import android.util.Base64;

import com.alibaba.fastjson.JSON;

String param = Base64.encodeToString(Uri.encode(JSON.toJSONString(map)).getBytes(), Base64.NO_WRAP).toString();
String url = "ontprovider://ont.io?param=".concat(param);
```

Ontology has implemented and made CEP-1 standard wallets available:

* [iOS](https://github.com/ontio-cyano/cyano-ios) version wallet
