## Description

Transfer token automatically from [Call](http://www.callchain.live/) to [SWTC](http://www.swtc.top/#/) chain. Support CALL token.

e.g. you transfer 1 `CALL` to [Call Fingate](http://block.callchain.live/#/account/cs9AWskwRmJrcMsszqC4hWeedCL5vSpexv) from your call address if success, the contract will automatically transfer 1 `JCALL` to your swtc address from [Jingtum Fingate](https://explorec9d536e.jccdex.cn/#/wallet/?wallet=jMCJrXRmycsT5tsVuge7Y65v9MrQi9r11E) in a few minutes.

## Installtion

```shell
npm install jcc-call-utils
```

## Usage

```javascript
// demo
import CallFingate from "jcc-call-utils";

// websocket server
const server = "";

const instance = new CallFingate(server);

const testSecret = "shaXxkbcS8NoHrL1TzTfWBRCbsD2K";

const testAddress = "c3oPNfL3k3EUTBQMFQ2LTZM5W5TUM7Qq5N";

// Don't change it. The fingate address is it for now.
const destination = "cs9AWskwRmJrcMsszqC4hWeedCL5vSpexv";
