Tutorial for using Inner Transactions using PyTEAL

it contains:

• Example Scenario (License Manager Contract)
• additional PyTEAL code examples for Inner Transactions
• bash script for (automatically) executing functions of the License Manager Contract using the goal SDK

How to run your own version:

First you need to have a PyTEAL version that supports TEAL v5 installed. Therefore you can just go to the PyTEAL github repository and get the latest version of PyTEAL:

git clone https://github.com/algorand/pyteal.git
cd pyteal
pip install -e 

Then you can grab the repository: git clone https://github.com/JuWeber99/algorand-innerTxn-tutorial

To then run it in the sandbox:

#host >$SANDBOX_DIR/sandbox up dev

Get 2 Account addresses from the output of goal account list and paste them into the app_creator and client variables of the interactions.sh bash script under $REPO_DIR/src/interactions.sh Then you can copy the compiled contract and the bash script to your sandbox:

#host >$SANDBOX_DIR/sandbox copyTo $REPO_DIR/src/interactions.sh
#host >$SANDBOX_DIR/sandbox copyTo $REPO_DIR/innerTxn_tutorial_pyteal.teal

Now you are ready to go!

Execute interactions

Now you can use the interactions.sh bash script to interact with the application!

#host >$SANDBOX_DIR/sandbox enter algod
#sandbox >chmod +x interactions.sh 
#sandbox >./interactions.sh
