 * A four-validator network with all nodes operated by Mysten Labs. Clients send transactions and read requests via this endpoint: https://gateway.devnet.sui.io:443/ using [JSON-RPC](../build/json-rpc.md)

 * A [Discord channel](https://discordapp.com/channels/916379725201563759/971488439931392130) for requesting test coins that can be used to pay for gas on the test network. These coins have no financial value and will disappear each time we reset the network.
 
-Many improvements to the Sui DevNet are underway, such as the ability to run full nodes and use a browser-based wallet.

 In addition, to conduct advanced work such as publishing a Move module or making a Move call, also obtain the [Sui source code](../build/install.md#source-code); for simplicity, we recommend installing in `~/sui` or using an environment variable.
