This project serves as a simple wrapper around Tenderly's Simulation API, enabling private use of the Tenderly access token and secure interaction with the Tenderly API.

• Node.js
• npm or yarn
• Cloudflare account
• Wrangler CLI

To run this project locally, you need to install the dependencies and use Wrangler's dev command to start the development server.

The deployed Cloudflare worker can be accessed at: https://safesnap-simulation.gnosisguild.workers.dev

1. Clone the repository:

git clone url_to_repository
cd safesnap-simulation

2. Install dependencies:

npm install

or if you use yarn:

yarn install

3. Start the local development environment with Wrangler:

wrangler dev

The following is an example of a simulation body for bundle transactions:

{
  "simulations": [
    {
      "network_id": "",
      "from": "",
      "to": "",
      "input": "",
      "value": "",
      "save": true,
      "save_if_fails": true,
      "gas": 8000000,
      "gas_price": 0,
      "simulation_type": "full"
    }
  ]
}

This command starts a local server where you can test your worker. It automatically reloads your worker when you make changes to the source code.

To deploy the worker to Cloudflare Workers, you need to configure your project with the necessary environment variables and use the wrangler deploy command.

The worker requires the following environment variables to connect to the Tenderly API:

• TENDERLY_USER: Your Tenderly username. Set this variable in wrangler.toml.
• TENDERLY_PROJECT: The Tenderly project name. Set this variable in wrangler.toml.
• TENDERLY_ACCESS_KEY: This should be kept secret. It is added to the Cloudflare worker via API in a GitHub Action. You can also manually add this using the Cloudflare Dashboard for local testing or staging environments.

1. To deploy the worker to Cloudflare, ensure you have set up your wrangler.toml with the correct account details and environment variables (excluding the secret TENDERLY_ACCESS_KEY).

2. Deploy your worker to Cloudflare Workers:

wrangler publish

Ensure that TENDERLY_ACCESS_KEY is securely added to your Cloudflare Worker as described in the "Environment Variables" section.
