# mypy-boto3-managedblockchain — Type annotations for boto3 ManagedBlockchain 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 277.0K/mo

## What it is and what it does

This package is a type stub library that adds complete type annotations to boto3's ManagedBlockchain service. It is generated automatically from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with mypy, pyright, VSCode, PyCharm, Emacs, Sublime Text, and other IDE and type-checker tools. When installed, it enables IDE code completion and static type checking for ManagedBlockchain API calls without requiring explicit type annotations in your code.

The package is a stub-only library (no runtime code) that depends only on typing-extensions. It supports Python 3.9 through 3.14 and is designed to be installed alongside boto3-stubs or used standalone. The documentation notes potential performance considerations for some IDEs and suggests alternatives when needed.

Use it for:

- Enable IDE autocomplete and type hints when writing boto3 ManagedBlockchain client code in VSCode or PyCharm.
- Run mypy or pyright type checking on code that calls boto3 ManagedBlockchain APIs to catch type errors before runtime.
- Use TYPE_CHECKING guards to import type annotations without adding a runtime dependency to production deployments.
- Improve code maintainability by catching incorrect ManagedBlockchain API calls during development rather than at runtime.

## Worth the install?

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

Provides type annotations and IDE autocompletion for boto3's ManagedBlockchain service, enabling static type checking with mypy, pyright, and other tools.

Yes, if you use boto3's ManagedBlockchain service and want IDE autocompletion or static type checking. Install friction is minimal, maintenance is active, the license is permissive, and there are no known vulnerabilities.

## Install

pip install mypy-boto3-managedblockchain
uv add mypy-boto3-managedblockchain
poetry add mypy-boto3-managedblockchain

## Installing mypy-boto3-managedblockchain

Before you install: Low install friction with a single lightweight runtime dependency (typing-extensions). Actively maintained with recent releases and no known vulnerabilities.

License in practice: MIT license permits free use, modification, and distribution with minimal restrictions—suitable for both open-source and commercial projects.

Quickstart:

python -m pip install mypy-boto3-managedblockchain

from boto3.session import Session
from mypy_boto3_managedblockchain import ManagedBlockchainClient

client: ManagedBlockchainClient = Session().client("managedblockchain")

Requires boto3 to be installed separately; type checking requires mypy, pyright, or a compatible IDE.

Verify before relying:

- Whether performance issues with Literal overloads mentioned in the excerpt have been resolved in recent versions.
- Whether the lite variant is recommended as the default for new projects.
