📃 About

The following repository hosts the source codes for:

• AlgoWorld Swapper's algorand smart signatures.
• AlgoWorldExplorer's stateful smart contracts for card auctions and card trading. Modified version of OpenNFT's smart contracts.

⚠️ NOTE: These contracts were created in collaboration with Solution Architect from Algorand (credits @cusma) and audited by TENSET security. Code is provided under MIT license.

Prerequisites

• poetry
• pre-commit
• Algorand Sandbox
• Docker

🚀 Overview

AlgoWorld currently offers several smart signatures used for swapping on AlgoWorld Swapper.

---

If you are looking to install algoworld contracts into your project run the following command:

pip install algoworld-contracts

Example usage

from algoworld_contracts import contracts

# Replace inputParams with real values
asa_to_asa_swap = contracts.get_swapper_teal(
        inputParams.creator_address,
        inputParams.offered_asa_id,
        inputParams.offered_asa_amount,
        inputParams.requested_asa_id,
        inputParams.requested_asa_amount,
        inputParams.incentive_wallet,
        inputParams.incentive_fee,
    )

# asa_to_asa_swap is a string of TEAL code
response = algod.compile(asa_to_asa_swap)
...

Swapper

There are two main types of smart signatures available:

• ASA to ASA swap | 🎴↔️🎴: Smart signature that allows performing a swap of any single ASA of specified amount to any other single ASA of specified amount.

• • Swap Configuration Proxy 📝: Smart signature that powers the AlgoWorld Swapper by allowing users to issue certain transactions that contain links to swap configuration files stored as .json files on ipfs. Proxy is then used to obtain those ipfs files by grabbing the latest pay transaction using Algorand Indexer queries.

• ASAs to ALGO swap | 🎴🎴🎴↔️💰: Smart signature that allows performing a swap of multiple ASAs of specified amount to ALGO of specified amount.

⚙️ Installation

This section assumes that poetry and pre-commit are installed and executed from the root folder of this repository.

1. Clone the repo

git clone https://github.com/AlgoWorldNFT/algoworld-contracts

2. Install python requirements

poetry install # install all dependencies
poetry shell # activate virtual env

(OPTIONAL) 3. Configure pre-commit hooks

pre-commit install

If you are not going to setup pre-commit locally, there is a Github Actions plugin that will autoformat your branch if you are opening a PR with commits that contain un-formatted code.

🧪 Testing

Testing assumes that docker-compose is installed and available. Project is relying on pytest-docker-compose plugin that automatically boots up temporary algorand sandbox and destroys the containers after the tests are finished.

(.venv) pytest

You can also include [pytest] into your commit message to trigger the test in CI pipeline on push action (on pr it is triggered automatically).
