This is a Work In Progress Some functionality is not yet supported by all the SDKs. Expect errors for now.

Demo of implementation for contract and client code that conforms to the ARC4 spec.

https://github.com/algorandfoundation/ARCs/blob/main/ARCs/arc-0004.md

ARC-004 or the Algorand ABI is a specification for encoding and decoding of data types and a standard for handling method calls.

contract.py - A PyTEAL contract that generates a set of methods that can be called as ABI methods contract.json - A JSON file describing the interface of the contract to be read by SDK clients js/ - Directory containing a TypeScript client to read in the contract.json file and call methods py/ - Directory containing a Python client to read in the contract.json file and call methods

Install the sandbox to start a local private node and start it with the dev configuration.

If you're in the sandbox directory run:

./sandbox up dev

First make sure you have the latest PyTEAL package installed

Next, clone this repository and cd to the root directory.

Create the application: Run ./manage.sh create This will create the teal source files in approval.teal and clear.teal, copy them to the sandbox, and call the create app transaction. It will print the newly created app id and cache it in a local file .app_id you may have to modify the path to the sandbox shell script you've installed)

If you update the PyTEAL source: Run ./manage.sh update This will recreate the teal source files, copy them to the sandbox, and call the update app transaction. It will use the cached app id from .app_id

Update the contract.json file by swapping in your new app id, then check the Language specific README files to see how to call the methods.

You'll also need to tweak the hostnames/ports for the algod client in their respective directories depending on how your local sandbox is configured.
