# Exchange API

## Ontology Exchange Docking Document

There are two kinds of assets that are part of the Ontology system: **native assets** and **contract assets**.

Native assets are `ONT` and `ONG`. Upon integration with exchange platforms they are enabled to process exchange and redeeming of these tokens.

### Deploying a Synchronization Node

There are two ways to deploy Ontology synchronization nodes:

#### Get from source code

Clone ontology repository to **$GOPATH/src/github.com/ontio** directory

```bash
$ git clone https://github.com/ontio/ontology.git
```

Or

```
$ go get github.com/ontio/ontology
```

Use the third-party package management tool glide to manage the dependent libraries

```
$ cd $GOPATH/src/github.com/ontio/ontology
$ glide install
```

Compile source code with make

```
$ make
```

An executable program will be generated after a successful compilation (using `make all` command will generate sig server under 'tools' directory ）

* `ontology`: Node program/node control program provided by command line

#### Get from release

[release page](https://github.com/ontio/ontology/releases)

#### Server deployment

1. **Create wallet(not mandatory for sync node)**

Create the wallet file `wallet.dat` that is required for nodes running through the CLI

```bash
$ ./ontology account add -d
Use default setting '-t ecdsa -b 256 -s SHA256withECDSA' 
    signature algorithm: ecdsa 
    curve: P-256 
    signature scheme: SHA256withECDSA

Create account successfully.
```
