# The Kima SDK
Because the Kima blockchain is a public network, you can interact with it however you see fit. You can choose to become a validator, if you want - see Becoming a Validator for more details - or you can build a variety of applications on top of it.
To make developing on top of Kima simpler, we have created a toolkit - the Kima Software Development Kit (SDK).
We provide:
* a standalone server that you can run locally and use as middleware that sits between the front end of your dApp and the Kima blockchain, submitting requests and returning the response to the front end
* a front-end widget with different configuration options that you can easily integrate into your dApp
Of course, the open ethos of Web3 means that you can develop your own solutions from scratch, but we strongly recommend building with both front end and back end components of our SDK so you can leverage the efforts our development team have made on your behalf.
### Troubleshooting
There is an extra step that may be required in some test environments if you are using Kima's tools to transfer to or from Solana wallets. In those environments, the recipient wallet may need to be "primed" by receiving a small amount of USDK before transfers or payments via Kima can take place.
