# Permissions

체인에서 Permissions 모듈 관련 데이터를 쿼리하는 예제 코드 스니펫입니다.

## gRPC 사용

### 모든 네임스페이스 조회

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcPermissionsApi = new ChainGrpcPermissionsApi(endpoints.grpc);

const allNamespaces = await chainGrpcPermissionsApi.fetchAllNamespaces();

console.log(allNamespaces);
```

### denom으로 네임스페이스 조회

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcPermissionsApi = new ChainGrpcPermissionsApi(endpoints.grpc);

const subdenom = "NINJA";
const includeRoles = true;

const namespace = await chainGrpcPermissionsApi.fetchNamespaceByDenom({
  subdenom,
  includeRoles: includeRoles,
});

console.log(namespace);
```

### denom을 기준으로 주소에 연결된 모든 역할 조회

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcPermissionsApi = new ChainGrpcPermissionsApi(endpoints.grpc);

const injectiveAddress = "inj...";
const subdenom = "NINJA";

const addressRoles = await chainGrpcPermissionsApi.fetchAddressRoles({
  injectiveAddress,
  denom: subdenom,
});

console.log(addressRoles);
```

### denom의 특정 역할에 연결된 모든 주소 조회

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcPermissionsApi = new ChainGrpcPermissionsApi(endpoints.grpc);

const subdenom = "NINJA";
const role = "role";

const addressesByRole = await chainGrpcPermissionsApi.fetchAddressesByRole({
  subdenom,
  role: role,
});

console.log(addressesByRole);
```

### 특정 Injective 주소의 바우처 조회

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcPermissionsApi = new ChainGrpcPermissionsApi(endpoints.grpc);

const injectiveAddress = "inj...";

const vouchers = await chainGrpcPermissionsApi.fetchVouchersForAddress(
  injectiveAddress
);

console.log(vouchers);
```
