pyteal-utils

pyteal-utils is a Python library providing reusable utility functions and classes for PyTEAL, the Python language binding for Algorand's Transaction Execution Approval Language (TEAL). It helps developers write more concise and maintainable smart contracts on the Algorand blockchain by abstracting common patterns and operations.

Key Features

• Inline Assembly — Inject raw TEAL source code directly into PyTEAL programs for low-level control.
• Math Utilities — Functions for mathematical operations like factorial, logarithms, exponentiation, min/max, and saturation.
• Storage Helpers — Classes and methods for working with global and local storage as binary large objects (blobs), with safe getters and defaults.
• String Operations — Convert between integers and byte strings, extract prefixes/suffixes, and handle uvarint encoding.
• Transaction Checks — Assertions for common transaction validations like fee minimums, rekeying, and close-to fields.
• Inner Transaction Builders — Utilities for creating payment and asset transfer inner transactions.

Philosophy

The library aims to reduce boilerplate in Algorand smart contract development by providing tested, reusable components that follow PyTEAL's patterns, allowing developers to focus on contract logic rather than repetitive low-level code.
