# Token Factory

查询链上 token factory 模块相关数据的示例代码片段。

## 使用 gRPC

### 获取 *creator* 创建的所有 denom

```ts lines highlight={1} theme={null}
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcTokenFactoryApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcTokenFactoryApi = new ChainGrpcTokenFactoryApi(endpoints.grpc);

const creator = "inj...";
const denoms = await chainGrpcTokenFactoryApi.fetchDenomsFromCreator(creator);

console.log(denoms);
```

### 获取 denom 权限元数据（即获取代币的 admin）

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcTokenFactoryApi = new ChainGrpcTokenFactoryApi(endpoints.grpc);

const creator = "inj...";
const subdenom = "NINJA";
const metadata = await chainGrpcTokenFactoryApi.fetchDenomAuthorityMetadata(
  creator,
  subdenom
);

console.log(metadata);
```
