Encoding/decoding Bech32 and Bech32m
Decision gist · record as of 2026-08-14
Yes, if you need a simple, dependency-free Bech32/Bech32m codec and can accept that the package will not receive updates. The implementation is stable and well-suited to production use for encoding and decoding, but do not install if you expect ongoing maintenance or compatibility updates as blockchain standards evolve.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- Installation is frictionless—a pure Python wheel with no runtime dependencies.
- However, the package is abandoned: the last commit was 2023-07-13, over a year ago, and no updates have been released since 2023-06-14.

Verify before relying

# Decode Bech32m string

- Compatibility with the latest Bitcoin or blockchain protocol updates since the last release in June 2023.
What it is and what it does
bech32m is a Python library that implements encoding and decoding for Bech32 and Bech32m, the checksummed base32 address formats used in Bitcoin and blockchain systems. It provides the core operations needed to convert between raw data and human-readable, error-detecting address strings.
The package requires Python 3.9 or later and has no external runtime dependencies, making it lightweight and easy to integrate. It is classified as production-stable but has been abandoned since mid-2023, meaning no new features or bug fixes are planned. Use it when you need a straightforward, dependency-free implementation of these encoding standards for existing applications, but be aware you cannot rely on upstream maintenance.
Use it for
- Validate or generate Bitcoin addresses in applications that work with blockchain wallets or payment systems.
- Encode raw public keys or hashes into human-readable Bech32m format for display or transmission.
- Decode user-supplied Bech32 or Bech32m strings to extract the underlying data and verify checksums.
- Integrate Bech32 encoding into command-line tools or scripts that interact with Bitcoin or similar blockchain networks.
