# RPC and Trade Execution

### RPC URLs <a href="#rpc-urls" id="rpc-urls"></a>

Because Adrena is a decentralized exchange, querying of data and submitting of transactions is done through an RPC URL.

There are currently 3 RPC options to choose from. You can select which RPC you prefer to use by clicking settings on the top right of the screen after your wallet is connected. There is also an 'automatic switch' button which will automatically choose the best RPC endpoint based on latency.

Below are the 3 RPC options:

* [Triton](https://docs.triton.one/)
* [Helius](https://docs.helius.dev/)
* \[Custom] - you can enter your own RPC url

### Trade Execution
