# Filecoin 交易发送引擎

作为 Filecoin 网络的 PiB 级数据载入工具，Swan Client 可以帮助用户处理数据，并将数据发送给 Filecoin 网络中的存储提供商。 主要功能及步骤如下

* 通过 graphsplit, lotus, IPFS, 或 ipfs-car 从源文件生成 CAR 文件
* 将 CAR 文件上传至 IPFS 服务器，并生成发送离线订单需要的元数据文件 (JSON 和 CSV)
* 基于元数据文件发送离线订单
* 生成一个最终元数据文件，供存储提供商导入订单
* 在 [Swan Platform](https://console.filswan.com/#/dashboard) 上创建任务和离线订单

  **(存储供应商可以通过** [**Swan Provider**](https://github.com/filswan/go-swan-provider/tree/release-2.1.0-rc1) **自动导入订单)**

Swan Client 支持创建三种不同的任务，帮助用户将数据发送至存储供应商。从源文件到成功发送订单的整个流程如下：
