# pytoniq-core-fork — TON Blockchain SDK

License: unclear · Maintenance: active · Downloads: 178.4K/mo

## What it is and what it does

pytoniq-core-fork is a Python SDK for working with TON Blockchain data structures and cryptography. It provides low-level primitives for serializing and deserializing TON cells (the fundamental data unit), handling addresses, performing cryptographic operations (key generation, signing, verification), and verifying Merkle proofs. The package also includes TL-schema (de)serialization and wrappers for common TON blockchain schemes.

This fork extends the original pytoniq-core to support Python 3.7, 3.8, and 3.9, whereas the upstream package requires Python 3.10 or later. It is actively maintained and carries no known security vulnerabilities. The package is designed for developers building TON blockchain applications, wallets, or tools that need to work with TON's native data formats and cryptographic operations.

Use it for:

- Building TON blockchain wallets or transaction signers that need to serialize cells and manage cryptographic keys.
- Verifying Merkle proofs for TON blockchain state validation or light-client implementations.
- Parsing and constructing TON smart contract messages using TL-schema serialization.
- Generating TON addresses and mnemonics for account creation and key management.
- Integrating TON blockchain interaction into Python applications targeting older Python versions (3.7–3.9).

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides TON Blockchain SDK primitives for Python 3.7–3.14, including cell serialization, cryptography, Merkle proof verification, and TL-schema (de)serialization.

Yes, if you are building on TON Blockchain and need Python 3.7–3.9 support. The package is actively maintained, has low install friction, and carries no known vulnerabilities. However, verify the license status before use in proprietary projects, and confirm that the fork's feature set meets your needs relative to the original upstream package.

## Install

pip install pytoniq-core-fork
uv add pytoniq-core-fork
poetry add pytoniq-core-fork

## Installing pytoniq-core-fork

Before you install: Low install friction; pure Python wheel. Active maintenance as of 2026-03-02. Depends on six cryptographic and utility libraries (bitarray, x25519, PyNaCl, pycryptodomex, requests, typing_extensions), all common and well-maintained.

License in practice: License status is unclear—no SPDX identifier or raw license text provided. Verify the license before using in proprietary or commercial projects.

Quickstart:

pip install pytoniq-core-fork

from pytoniq_core_fork import Cell, Address

cell = Cell()
address = Address("EQBvW8Z5huBkMJYdnfAEM5JqTNkuWX3diqYENkWsIL0XggGG")

Requires Python >= 3.7; the fork extends compatibility to 3.7–3.9, which the original package did not support.

Verify before relying:

- Whether the fork maintains feature parity with the original pytoniq-core beyond Python version compatibility.
- Specific use cases and maturity level within the TON ecosystem (e.g., production readiness, adoption by major projects).
- Why the license is unspecified and what the original upstream project's license is.
