Desktop Notifications - USDT Transfers

Live Desktop Notifications for USDT transfers. This project is from a Moralis Web3 tutorial found here.

Setup project:

1. Clone project

2. Run the project:

   npm i
   npm start

3. Run ngrok: (so external service can reach your local project)

   ngrok http 3000

   You should see something like the following; the Forwarding url you will want to use is the https:// version:

   ngrok by @inconshreveable
   
   Session Status                online
   Account                       Hamster Phomstentein (Plan: Cheesy)
   [...]
   Web Interface                 http://127.0.0.1:4040
   Forwarding                    http://78be-136-175-97-43.ngrok.io -> localhost:3000
   Forwarding                    https://78be-136-175-97-43.ngrok.io -> localhost:3000
   

4. Test your project is running:

   You can curl (see below) or use a service like Postman to confirm the endpoints are functioning. I recommend doing this before you set up an external service (like Moralis) to point to your project.

   • Localhost test:

     curl --location --request POST 'localhost:3000/webhook' \
     --header 'Content-Type: application/json' \
     --data-raw '{
         "time": "hamster time"
     }'

   • Ngrok test:

     Get your https forwarding url from your ngrok session, and replace {ngrok_url} below:

     curl --location --request POST '{ngrok_url}/webhook' \
     --header 'Content-Type: application/json' \
     --data-raw '{
         "time": "hamster time"
     }'

5. Setup Moralis:

   1. Go to your Moralis Dashboard

      You can create a Moralis account here: https://admin.moralis.io/register

   2. Go to Streams:

      • Navigate to "New Stream" -> "Create From Scratch"

   3. Fill in the following Stream Details:

      # This will be the USDT transfers (that are over $50,000);
      ## To find this manually:
      ##   - Go to Etherscan (https://etherscan.io)
      ##   - type "usdt" in search input
      ##   - click on the result "Tether USD (USDT)"
      ##   - copy the `Profile Summary` -> `Contract` address
      ##     (0xdAC17F958D2ee523a2206206994597C13D831ec7)
      Address: "0xdAC17F958D2ee523a2206206994597C13D831ec7"
      
      Listen to all addresses: false
      
      Description: "USDT Transfers Over 50K"
      
      # This is the `https` Ngrok url you got from previous steps.
      ## IMPORTANT: Don't forget to append the `/webhook` to the end!
      Webhook URL: "https://{your-ngrok-subdomain}.ngrok.io/webhook"
      
      Select Networks:
        - "Ethereum Mainnet"
      
      Address Activity:
        - "Contract interactions (logs)"
      
      Event Emittance: true
      
      # (Application Binary Interface)
      # You will need this in order to select options under the next step for
      # "Select Topic0"
      ## Find this on the USDT Etherscan page:
      ##  - Scroll down and select the `Contract` tab
      ##  - Scroll down to the `Contract ABI` section
      ##  - Click the "Copy ABI to clipboard" icon
      ABI: [excluded for brevity]
      Select Topic0:
        - "Transfer(address,address,uint256)"
      
      # This is where you can filter the results before they hit your project.
      ## For additional filters: https://github.com/MoralisWeb3/streams-beta#filter-streams
      ##
      ## NOTE: REMOVE the trailing comma's or Moralis will error (my code
      ## formatter keeps adding them back in).
      Advanced Options (optional):
        [
          {
            "topic0": "Transfer(address,address,uint256)",

          },
        ]
