# Send and Receive in Different Tasks

import { Callout } from 'nextra/components'

<Callout type="warning">
  There will be a breaking SDK upgrade in the coming months. This upgrade will make the SDK a lot easier to build with.

This upgrade will affect the interface of the SDK dramatically, and will be coupled with a protocol change - stay tuned for information on early access to the new protocol testnet.

It will also be coupled with the documentation of the SDK on [crates.io](https://crates.io/).

If you need to split the different actions of your client across different tasks, you can do so like this. You can think of this analogously to spliting a Tcp Stream into read/write. This functionality is also useful for embedding a sending and receiving client into different tasks.
