Scripts and Smart Contract

README.md

+# Setup
+
+1. Install [Docker Desktop](https://www.docker.com/products/docker-desktop)
+2. Install [Algorand sandbox](https://github.com/algorand/sandbox)
+3. Add this project folder as bind volume in sandbox `docker-compose.yml` under key `services.algod`:
+    ```yml
+    volumes:
+      - type: bind
+        source: <path>
+        target: /data
+    ```
+4. Start sandbox:
+    ```txt
+    $ ./sandbox up
+    ```
+5. Install Python virtual environment in project folder:
+    ```txt
+    $ python -m venv venv
+    $ source ./venv/Scripts/activate # Windows
+    $ source ./venv/bin/activate # Linux
+    ```
+6. Use Python interpreter: `./venv/Scripts/python.exe`
+    VSCode: `Python: Select Interpreter`
+
+# Scripts
+
+`call.sh`
+`grouped_txn.sh`
+`parallel_calls.sh`
+`vars.sh`
