Aptos Python SDK

This provides basic functionalities to interact with Aptos. Get started here.

Currently this is still in development and may not be suitable for production purposes.

Note: The sync client is deprecated, please only start new projects using the async client. Feature contributions to the sync client will be rejected.

Requirements

This SDK uses Poetry for packaging and dependency management:

curl -sSL https://install.python-poetry.org | python3 -
poetry install

Unit testing

make test

E2E testing

First, run a local testnet (run this from the root of aptos-core):

cargo run -p aptos -- node run-local-testnet --with-faucet --faucet-port 8081 --force-restart --assume-yes

Next, tell the end-to-end tests to talk to this locally running testnet:

export APTOS_NODE_URL="http://127.0.0.1:8080/v1"
export APTOS_FAUCET_URL="http://127.0.0.1:8081"

Finally run the tests:

make examples

Note: These end-to-end tests are tested against a node built from the same commit as part of CI, not devnet. For examples tested against devnet, see developer-docs-site/static/examples/python/ from the root of the repo.

Autoformatting

make fmt

Generating types

The Python openapi-python-client tool cannot parse references. Therefore there are three options:

• Use swagger-cli to dereference, gain a type explosion, and still have missing types
• Live without missing types
• Write a pure python implementation with no autogenerated code

Currently the team is moving forward with pure python, but leaves the following notes for the curious:

npm install  -g @apidevtools/swagger-cli
swagger-cli bundle --dereference ../../../api/doc/v0/openapi.yaml  -t yaml > openapi.yaml
python3 -m openapi_python_client generate --path openapi.yaml
mv aptos-dev-api-specification-client/aptos_dev_api_specification_client/ aptos_sdk/openapi

Semantic versioning

This project follows semver as closely as possible
