# Distribution

Example code snippets to query data related to delegating to validators from the chain.

## Using gRPC

### Fetch parameters such as the base and bonus proposer reward

```ts theme={null}
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcDistributionApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcDistributionApi = new ChainGrpcDistributionApi(endpoints.grpc);

const moduleParams = await chainGrpcDistributionApi.fetchModuleParams();

console.log(moduleParams);
```

### Fetch the amount and denom of rewards for a delegator delegating to a specific validator

```ts theme={null}
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcDistributionApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcDistributionApi = new ChainGrpcDistributionApi(endpoints.grpc);

const delegatorAddress = "inj...";
const validatorAddress = "injvaloper...";

const delegatorRewardsFromValidator =
  await chainGrpcDistributionApi.fetchDelegatorRewardsForValidatorNoThrow({
    delegatorAddress,
    validatorAddress,
  });

console.log(delegatorRewardsFromValidator);
```

### Fetch the amount and denom of all rewards for a delegator

```ts theme={null}
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcDistributionApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcDistributionApi = new ChainGrpcDistributionApi(endpoints.grpc);

const delegatorAddress = "inj...";

const totalDelegatorRewards =
  await chainGrpcDistributionApi.fetchDelegatorRewardsNoThrow(delegatorAddress);

console.log(totalDelegatorRewards);
```
