simulation_type API 参数允许您控制 Simulation API 返回结果的详细程度。它同时适用于单笔模拟和捆绑请求。

​
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。
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。

​
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。
request.ts

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`,

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。

  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

      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

      },
    },

  console.timeEnd('Simulation');

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