# Helios Remote Procedure Calls
|
|
|
|
Helios provides a variety of RPC methods for interacting with the Ethereum network. These methods are exposed via the `Client` struct. The RPC methods follow the [Ethereum JSON RPC Spec](https://ethereum.github.io/execution-apis/api-documentation). See [examples](./examples/readme.rs) of running remote procedure calls with Helios.

|
|
|
|
| RPC Method | Client Function | Description | Example |
|
|
