ETH Tech Tree Backend

This express server application is used to grade submitted challenges from the ETH Tech Tree

Requirements

Before you begin, you need to install the following tools:

• Node (>= v18.17)
• Yarn (v1 or v2+)
• Git

Getting Started

1. Clone this repo & install dependencies

   git clone https://github.com/BuidlGuidl/eth-tech-tree-backend.git
   cd eth-tech-tree-backend
   yarn install
   

2. Set up your environment variables: Make a copy of the .env.example file and name it .env.local and fill in the required environment variables.

   Set up an Etherscan API Key. Also set up the MONGODB_URI pointing to a local or hosted MongoDB instance.

3. Seed the database:

   seed.example.json will be used to seed the data. Modify it as needed if you are adding or modifying collections. Run the following command (notice how we add the environment variable then run yarn seed):

   MONGODB_URI=mongodb://localhost:27017/your-db-name yarn seed

   To overwrite the existing data use yarn seed --reset.

4. Install challenge folders where tests will be executed

   yarn install:challenges

5. Start the server at localhost:3000

   yarn dev

6. Test a challenge submission for token wrapper weth at the following endpoint

   POST
   localhost:3000/submit
   

   With this body:

   {
   "challengeName": "token-wrapper-weth",
   "network": "sepolia",
   "contractAddress": "0xCa359ee2DF0CE120a9eDa850Aa743fC2b4F1ade9",
   "userAddress": "0x60583563D5879C2E59973E5718c7DE2147971807"
   }
   

   To test a failing contract use this as the contract address:

   0x4c45da107F95d8Ed27951EbDD4CF4CC56B47A83F
