This repository contains a Node.js script to sign typed data according to the ERC-7512 standard. The script is written in TypeScript and uses the Ethers.js library to interact with the Ethereum blockchain.

• Prerequisites
• Installation
• Environment Setup
• Running the Script

• Node.js
• npm (comes bundled with Node.js) or Yarn

1. Clone this repository:

   git clone git@github.com:OnchainAudit/tooling.git

2. Navigate to the project directory:

   cd tooling/simple_signer

3. Install the required dependencies:

   npm install

   or if you're using Yarn:

   yarn install

1. Rename the .env.template file to .env.

2. Open the .env file and paste your Ethereum private key next to YOUR_PRIVATE_KEY=. Ensure there are no spaces between the = sign and your private key.

   Example:

   YOUR_PRIVATE_KEY=0xYOUR_PRIVATE_KEY_HERE
   

3. Save the .env file.

With the environment set up, you can run the script using the following command:

npm start

or if you're using Yarn:

yarn start

Note: Always ensure that your .env file is added to your .gitignore to prevent accidentally pushing sensitive information to public repositories. The .env.template serves as a placeholder to guide users on how to set up their environment variables without exposing any sensitive data.
