# 读取私密历史记录

> 从索引器读取钱包私密交易历史的指南，包括完整代码示例。

1. 使用专用的 RPC 方法从索引器读取加密交易。
2. 只有用户或用户授权的人才能使用他们的查看密钥解密历史记录。
3. 在钱包运行回填时使用：在钱包解锁、私密钱包打开、应用恢复、网络重新连接、流间隙或钱包恢复时。

        ### 前提条件

        <Info>
          The TypeScript examples require Node.js 24 or later, pnpm 11.18.0, and the Solana CLI.
        </Info>

        ```bash theme={"system"}
        pnpm add @heliuslabs/zolana @solana/kit
        ```

        Source: [sdk-libs/ts](https://github.com/helius-labs/zolana/tree/main/sdk-libs/ts)

        <Accordion title="Connect to Endpoints">

              pnpm install
              cp .env.example .env
              ```

              Add a [Helius API key](https://dashboard.helius.dev/):

              ```bash .env theme={"system"}
              API_KEY=YOUR_API_KEY
              ZOLANA_PAYER_KEYPAIR=~/.config/solana/id.json
              ```

              ```ts theme={"system"}
              import { createZolanaClient } from "@heliuslabs/zolana";

              const client = await createZolanaClient({
                solanaRpcUrl: "https://devnet.helius-rpc.com/?api-key=YOUR_API_KEY",
                indexerUrl: "http://zolnet-devnet-1779374825.eu-north-1.elb.amazonaws.com",
                proverUrl: "http://zolnet-devnet-1779374825.eu-north-1.elb.amazonaws.com:3001",
                allowInsecureHttp: true,
              });
              ```

              The examples use the Solana CLI wallet as the payer by default. The payer must hold devnet SOL. See [How to Get Devnet SOL](/docs/rpc/devnet-sol).
            </Tab>

            <Tab title="Localnet">
              On localnet the SDK starts the local test validator (`:8899`), Photon indexer (`:8784`), and prover (`:3001`), and the
              client connects to them automatically without needing endpoint configuration.

              ```bash theme={"system"}
              cargo install --git https://github.com/helius-labs/zolana --tag v0.1.0-alpha zolana-cli
              zolana dev start

        // The view tag is the sender's Solana public key in confidential rings.
        // Used by the indexer to fetch the sender's UTXOs.
        const senderViewTag =
          senderAddress.confidentialViewTag();
        ```

        * `senderViewTag` 是 `senderAddress.confidentialViewTag()`，发送者在机密环中的 Solana 公钥。索引器使用它返回匹配的加密输出。
      </Step>

      <Step>
        ### 从索引器获取交易输出

        ```typescript theme={"system"}
        import { atSlot } from "@heliuslabs/zolana/client";

        const depositResponse =
          await client.getShieldedTransactionsByTags(
            { tags: [senderViewTag] },
            atSlot(depositTx.slot),
          );
        ```

        * `getShieldedTransactionsByTags` 获取与 `senderViewTag` 关联的加密输出。
        * `atSlot(depositTx.slot)` 等待索引器在该槽位有存款。
        * 索引器返回加密输出数据。它不解密私密历史。
      </Step>

      <Step>
        ### 解密为私密历史

        ```typescript theme={"system"}
        import { Wallet } from "@heliuslabs/zolana";
        import { decryptTransactions } from "@heliuslabs/zolana/transaction";

        const wallet = new Wallet({
          identity: senderAddress,
          registry: assets,
        });
        await decryptTransactions({
          wallet,
          authority: {
            syncMaterial: () =>
              Promise.resolve({
                identity: senderAddress,
                viewingKeys: [senderKeypair.viewingKey()],
                nullifierKey: senderKeypair.nullifierKey(),
              }),
          },
          transactions: depositResponse.transactions,
        });
        const history = wallet.privateTransactions();
        ```

        * `senderKeypair` 提供发送者的查看密钥以进行本地解密。
        * `decryptTransactions` 解密匹配输出并将历史记录写入 `Wallet`。
        * `wallet.privateTransactions()` 阅读解密后的历史。
        * `decryptToBalances` 仅返回余额。

        **示例响应：**

        ```ts theme={"system"}
        [
          {
            id: { signature: "5x…", slot: 291044100n, index: 0n },
