Python implementation of Borsh serialization, built on the Construct library.
Decision gist · record as of 2026-08-14
No, unless you are already committed to this exact version or cannot migrate. The package is abandoned (last release October 2021, no commits since), and its dependencies may not be compatible with modern Python environments. For new projects, evaluate actively maintained Borsh implementations or alternative serialization formats.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >=3.8.3,<4.0.0; package is abandoned and may not work with Python versions released after 2021-10-20
- Low install friction with only two runtime dependencies (construct-typing and sumtypes).
- However, the package is archived and abandoned—last release was 2021-10-20 with no updates since, and the repository shows no recent commits.

Alternatives
Verify before relying
pip install borsh-construct
from borsh_construct import BorshConstruct
# Use construct-typing and sumtypes to define and serialize data structures- Whether construct-typing and sumtypes remain actively maintained and compatible with current Python versions
- Whether the Borsh specification has evolved since the package's last release and if this implementation remains compliant
- Real-world security audit status or known limitations in the implementation
What it is and what it does
borsh-construct provides a Python implementation of the Borsh binary serialization format, which is designed for security-critical applications where consistency, safety, and speed matter. It is built on top of the Construct library and uses construct-typing and sumtypes to define and work with binary-serialized data structures.
The package prioritizes strict specification compliance and is intended for use cases where deterministic serialization is required—particularly in cryptographic and hashing contexts. However, the package has been abandoned since its initial release in October 2021, with no subsequent updates or maintenance.
Use it for
- Serialize data structures for cryptographic hashing in blockchain or security-critical applications
- Ensure deterministic binary representation of objects across different systems or languages
- Integrate with NEAR Protocol or other systems that mandate Borsh serialization
- Decode Borsh-serialized data received from external security-critical systems
