# 地址转换

本文档将概述一些在不同格式和派生路径之间转换地址的示例。

### Hex ↔ Bech32 地址转换

正如我们在[钱包](../defi/wallet)部分提到的，Injective 地址与 Ethereum 地址兼容。你可以轻松地在两种格式之间进行转换。

### 使用 TypeScript

你可以使用 `@injectivelabs/sdk-ts` 包中的实用函数轻松地在 Injective 地址和 Ethereum 地址之间进行转换：

```typescript theme={null}
import {
  getEthereumAddress,
  getInjectiveAddress,
} from "@injectivelabs/sdk-ts/utils";

const injectiveAddress = "inj1...";
const ethereumAddress = "0x..";

console.log(
  "从 Ethereum 地址获取 Injective 地址 => ",
  getInjectiveAddress(ethereumAddress)
);
console.log(
  "从 Injective 地址获取 Ethereum 地址 => ",
  getEthereumAddress(injectiveAddress)
);
```

### **将 Cosmos 地址转换为 Injective 地址**

由于 Injective 的派生路径与默认的 Cosmos 派生路径不同，你需要账户的 `publicKey` 才能将 Cosmos `publicAddress` 转换为 Injective 地址。

### 使用 TypeScript

```typescript theme={null}
import { config } from "dotenv";
import { PublicKey } from "@injectivelabs/sdk-ts/core/accounts";
import { ChainRestAuthApi } from "@injectivelabs/sdk-ts/client/chain";

config();

(async () => {
  const chainApi = new ChainRestAuthApi(
    "https://rest.cosmos.directory/cosmoshub"
  );

  const cosmosAddress = "cosmos1..";
  const account = await chainApi.fetchCosmosAccount(cosmosAddress);

  if (!account.pub_key?.key) {
    console.log("未找到公钥");
    return;
  }

  console.log(
    "injectiveAddress",
    PublicKey.fromBase64(account.pub_key.key || "")
      .toAddress()
      .toBech32()
  );
})();
```
