# getInflationReward - Solana

Example code for the getInflationReward JSON-RPC method. Complete guide on how to use getInflationReward JSON-RPC in GetBlock Web3 documentation.

This method returns the inflation reward credited to a list of addresses for a given epoch. Addresses that received no reward return null.

| result    | array  | Array of reward objects or null entries, in the order of the supplied addresses |

### Reward Entry

| Field         | Type   | Description                                  |
| ------------- | ------ | -------------------------------------------- |
