# Distribution

查询链上与委托给验证者相关数据的示例代码片段。

## 使用 gRPC

### 获取参数，如基础和奖励提议者奖励

```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);
```

### 获取委托人委托给特定验证者的奖励金额和 denom

```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);
```

### 获取委托人的所有奖励金额和 denom

```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);
```
