# Staking

查询链上 staking 模块的示例代码片段。

## 使用 gRPC

### 获取 staking 模块相关参数，如解绑时间或绑定 denom

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

const moduleParams = await chainGrpcStakingApi.fetchModuleParams();

console.log(moduleParams);
```

### 获取池的未绑定和已绑定代币

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

const pool = await chainGrpcStakingApi.fetchPool();

console.log(pool);
```

### 获取验证者及相关元数据

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

const validators = await chainGrpcStakingApi.fetchValidators();

console.log(validators);
```

### 根据验证者地址获取验证者及相关元数据

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

const validatorAddress = "injvaloper...";

const validator = await chainGrpcStakingApi.fetchValidator(validatorAddress);

console.log(validator);
```

### 获取与验证者关联的委托

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { PaginationOption } from '@injectivelabs/sdk-ts/types'
import { ChainGrpcStakingApi } from '@injectivelabs/sdk-ts/client/chain'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

const validatorAddress = 'injvaloper...'
const pagination = {...} as PaginationOption

const delegations = await chainGrpcStakingApi.fetchValidatorDelegationsNoThrow({
  validatorAddress,
  pagination /* 可选分页选项 */
})

console.log(delegations)
```

### 获取与验证者关联的解绑委托

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { PaginationOption } from '@injectivelabs/sdk-ts/types'
import { ChainGrpcStakingApi } from '@injectivelabs/sdk-ts/client/chain'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

const validatorAddress = 'injvaloper...'
const pagination = {...} as PaginationOption

const unbondingDelegations = await chainGrpcStakingApi.fetchValidatorUnbondingDelegationsNoThrow({
  validatorAddress,
  pagination /* 可选分页选项 */
})

console.log(unbondingDelegations)
```

### 获取 injective 地址对特定验证者的委托

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

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

const delegation = await chainGrpcStakingApi.fetchDelegation({
  injectiveAddress,
  validatorAddress,
});

console.log(delegation);
```

### 获取 injective 地址的委托

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { PaginationOption } from '@injectivelabs/sdk-ts/types'
import { ChainGrpcStakingApi } from '@injectivelabs/sdk-ts/client/chain'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

const injectiveAddress = 'inj...'
const pagination = {...} as PaginationOption

const delegations = await chainGrpcStakingApi.fetchDelegationsNoThrow({
  injectiveAddress,
  pagination /* 可选分页选项 */
})

console.log(delegations)
```

### 获取验证者的委托人

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { PaginationOption } from '@injectivelabs/sdk-ts/types'
import { ChainGrpcStakingApi } from '@injectivelabs/sdk-ts/client/chain'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

const validatorAddress = 'injvaloper...'
const pagination = {...} as PaginationOption

const delegators = await chainGrpcStakingApi.fetchDelegatorsNoThrow({
  validatorAddress,
  pagination /* 可选分页选项 */
})

console.log(delegators)
```

### 获取 injective 地址的解绑委托

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { PaginationOption } from '@injectivelabs/sdk-ts/types'
import { ChainGrpcStakingApi } from '@injectivelabs/sdk-ts/client/chain'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

const injectiveAddress = 'inj...'
const pagination = {...} as PaginationOption

const unbondingDelegations = await chainGrpcStakingApi.fetchUnbondingDelegationsNoThrow({
  injectiveAddress,
  pagination /* 可选分页选项 */
})

console.log(unbondingDelegations)
```

### 获取 injective 地址的重新委托

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { PaginationOption } from '@injectivelabs/sdk-ts/types'
import { ChainGrpcStakingApi } from '@injectivelabs/sdk-ts/client/chain'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

const injectiveAddress = 'inj...'
const pagination = {...} as PaginationOption

const unbondingDelegations = await chainGrpcStakingApi.fetchReDelegationsNoThrow({
  injectiveAddress,
  pagination /* 可选分页选项 */
})

console.log(unbondingDelegations)
```
