# 模拟模式

> 选择 full 模式获取完整解码结果，abi 模式获取部分解码结果，或 quick 模式以获得更快的原始交易输出。

`simulation_type` API 参数允许您控制 [Simulation API](/simulations/overview) 返回结果的详细程度。它同时适用于[单笔模拟](/simulations/single-simulations)和捆绑请求。

## 模拟类型

* `full`（默认）：包含调用追踪、函数输入与输出、状态差异等的详细原始与解码信息。
* `quick`：最少的原始值。
* `abi`：包含解码后的输入、输出和日志的最少信息。

<Note>
  Full 模拟会花费更多时间，具体取决于调用追踪的深度。当您不需要解码信息时，请使用 quick 模拟。
</Note>

## Full 模拟模式

* **调用追踪**，包含函数名、在源文件中的位置、调用者地址及余额
* 解码后的**函数输入与输出**，所有参数附带 **soltype**。这适用于所有函数调用，包括来自 EOA 的对智能合约的直接调用、智能合约之间的内部调用，以及每个智能合约内部的函数调用。
* 解码后的**状态差异**（对状态的更改），修改的字段附带 **soltype**
* 解码后的**日志（事件）**，包括产生它们的 Solidity **event** 和事件参数的**值**，每一项附带 **type**。

## Quick 模拟模式

提供未经额外解码的原始数据。当您仅需要交易的基本详情时，此模式最为合适。

```ts title="request.ts" showLineNumbers theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}

dotenv.config();

const approveDai = async () => {
  // assuming environment variables TENDERLY_ACCOUNT_SLUG, TENDERLY_PROJECT_SLUG and TENDERLY_ACCESS_KEY are set
  // https://docs.tenderly.co/platform/account/projects/slug
  // https://docs.tenderly.co/platform/account/projects/api-tokens
  const { TENDERLY_ACCOUNT_SLUG, TENDERLY_PROJECT_SLUG, TENDERLY_ACCESS_KEY } = process.env;

  console.time('Simulation');

  const resp = await axios.post(
    `https://api.tenderly.co/api/v1/account/${TENDERLY_ACCOUNT_SLUG}/project/${TENDERLY_PROJECT_SLUG}/simulate`,
    // the transaction
    {
      /* Simulation Configuration */
      save: false, // if true simulation is saved and shows up in the dashboard
      save_if_fails: false, // if true, reverting simulations show up in the dashboard
      simulation_type: 'quick', // full, abi or quick (full is default)
      network_id: '1', // network to simulate on
      /* Standard EVM Transaction object */
      from: '0xdc6bdc37b2714ee601734cf55a05625c9e512461',
      to: '0x6b175474e89094c44da98b954eedeac495271d0f',

      gas: 8000000,
      value: 0,
    },
    {
      headers: {
        'X-Access-Key': TENDERLY_ACCESS_KEY as string,
      },
    },
  );
  console.timeEnd('Simulation');

  const transaction = resp.data.transaction;
  console.log(JSON.stringify(transaction, null, 2));
};

approveDai();
```

## ABI 模拟模式

**调用追踪**，包含函数名、解码后的输入与输出变量。

解码后的**日志（事件）**，包括产生它们的 Solidity **event** 和事件参数的**值**，每一项附带 **type** 描述。

```ts title="request.ts" showLineNumbers theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}

dotenv.config();

const approveDai = async () => {
  // assuming environment variables TENDERLY_ACCOUNT_SLUG, TENDERLY_PROJECT_SLUG and TENDERLY_ACCESS_KEY are set
  // https://docs.tenderly.co/platform/account/projects/slug
  // https://docs.tenderly.co/platform/account/projects/api-tokens
  const { TENDERLY_ACCOUNT_SLUG, TENDERLY_PROJECT_SLUG, TENDERLY_ACCESS_KEY } = process.env;

  console.time('Simulation');

  const resp = await axios.post(
    `https://api.tenderly.co/api/v1/account/${TENDERLY_ACCOUNT_SLUG}/project/${TENDERLY_PROJECT_SLUG}/simulate`,
    // the transaction
    {
      /* Simulation Configuration */
      save: false, // if true simulation is saved and shows up in the dashboard
      save_if_fails: false, // if true, reverting simulations show up in the dashboard
      simulation_type: 'abi', // full, abi or quick (full is default)
      network_id: '1', // network to simulate on
      /* Standard EVM Transaction object */
      from: '0xdc6bdc37b2714ee601734cf55a05625c9e512461',

      gas: 8000000,
      value: 0,
    },
    {
      headers: {
        'X-Access-Key': TENDERLY_ACCESS_KEY as string,
      },
    },
  );
  console.timeEnd('Simulation');

  const transaction = resp.data.transaction;
  console.log(JSON.stringify(transaction, null, 2));
};

approveDai();
