Package: cyber-sdk
The Python SDK for Cyber Protocol (Bostrom and Space Pussy Networks)(Unfamiliar with Cyber protocol?Check out the cyber~сongress github)Explore the Docs»PyPI Package·GitHub RepositoryThe Cyber Software Development Kit (SDK) in Python is a simple library toolkit for building software that can interact with the Bostrom / Space Pussy blockchains and provides simple abstractions over core data structures, serialization, key management, and API request generation.FeaturesWritten in Python with extensive support librariesVersatile support for key management solutionsExposes the Bostrom API through LCDClientTable of ContentsAPI ReferenceGetting StartedRequirementsInstallationDependenciesTestsCode QualityUsage ExamplesGetting Blockchain InformationAsync UsageBuilding and Signing TransactionsExample Using a WalletContributingReporting an IssueRequesting a FeatureContributing CodeDocumentation ContributionsLicenseAPI ReferenceAn intricate reference to the APIs on the Cyber SDK can be foundhere.Getting StartedA walk-through of the steps to get started with the Cyber SDK alongside a few use case examples are provided below. Alternatively, a tutorial video is also availablehereas reference.RequirementsCyber SDK requiresPython v3.7+.InstallationNOTE:All code starting with a$is meant to run on your terminal (a bash prompt). All code starting with a>>>is meant to run in a python interpreter, likeipython.Cyber SDK can be installed (preferably in avirtual environmentfrom PyPI usingpip) as follows:$pipinstall-Ucyber_sdkYou might havepip3installed instead ofpip; proceed according to your own setup.DependenciesCyber SDK usesPoetryto manage dependencies. To get set up with all the required dependencies, run:$pipinstallpoetry
$poetryinstallTestsCyber SDK provides extensive tests for data classes and functions. To run them, after the steps inDependencies:$maketestCode QualityCyber SDK usesBlack,isort, andMypyfor checking code quality and maintaining style. To reformat, after the steps inDependencies:$makeqa&&makeformatUsage ExamplesCyber SDK can help you read block data, sign and send transactions, deploy and interact with contracts, and many more.
The following examples are provided to help you get started. Use cases and functionalities of the Cyber SDK are not limited to the following examples and can be found in fullhere.In order to interact with the Cyber blockchain, you'll need a connection to a Cyber node. This can be done through setting up an LCDClient (The LCDClient is an object representing an HTTP connection to a Cyber LCD node.):fromcyber_sdk.client.lcdimportLCDClientcyber=LCDClient(chain_id="bostrom",url="https://lcd.bostrom.cybernode.ai/")Getting Blockchain InformationOnce properly configured, theLCDClientinstance will allow you to interact with the Cyber blockchain. Try getting the latest block height:cyber.tendermint.block_info()['block']['header']['height']'5490476'Async UsageIf you want to make asynchronous, non-blocking LCD requests, you can use AsyncLCDClient. The interface is similar to LCDClient, except the module and wallet API functions must be awaited.importasynciofromcyber_sdk.client.lcdimportAsyncLCDClientasyncdefmain():cyber=AsyncLCDClient("https://lcd.bostrom.cybernode.ai/","bostrom")total_supply=awaitcyber.bank.total()print(total_supply)awaitcyber.session.close# you must close the sessionasyncio.get_event_loop().run_until_complete(main())Building and Signing TransactionsIf you wish to perform a state-changing operation on the cyber blockchain such as sending tokens, swapping assets, withdrawing rewards, or even invoking functions on smart contracts, you must create atransactionand broadcast it to the network.
Cyber SDK provides functions that help create StdTx objects.Example Using a Wallet (recommended)AWalletallows you to create and sign a transaction in a single step by automatically fetching the latest information from the blockchain (chain ID, account number, sequence).UseLCDClient.wallet()to create a Wallet from any Key instance. The Key provided should correspond to the account you intend to sign the transaction with.fromcyber_sdk.client.lcdimportLCDClientfromcyber_sdk.key.mnemonicimportMnemonicKeymk=MnemonicKey(mnemonic=MNEMONIC)cyber=LCDClient("https://lcd.bostrom.cybernode.ai/","bostrom")wallet=cyber.wallet(mk)Once you have your Wallet, you can simply create a StdTx usingWallet.create_and_sign_tx.fromcyber_sdk.core.feeimportFeefromcyber_sdk.core.bankimportMsgSendfromcyber_sdk.client.lcd.api.tximportCreateTxOptionstx=wallet.create_and_sign_tx(CreateTxOptions(msgs=[MsgSend(wallet.key.acc_address,RECIPIENT,"1000000boot"# send 1_000_000 BOOT)],memo="test transaction!",fee=Fee(200000,"20000boot")))You should now be able to broadcast your transaction to the network.result=bostrom.tx.broadcast(tx)print(result)ContributingCommunity contribution, whether it's a new feature, correction, bug report, additional documentation, or any other feedback is always welcome. Please read through this section to ensure that your contribution is in the most suitable format for us to effectively process.Reporting an IssueFirst things first:Do NOT report security vulnerabilities in public issues!Please disclose responsibly by submitting your findings to theBostrom Bugcrowd submission form. The issue will be assessed as soon as possible.
If you encounter a different issue with the Python SDK, check first to see if there is an existing issue on theIssuespage, or if there is a pull request on thePull requestspage. Be sure to check both the Open and Closed tabs addressing the issue.If there isn't a discussion on the topic there, you can file an issue. The ideal report includes:A description of the problem / suggestion.How to recreate the bug.If relevant, including the versions of your:Python interpreterBostrom SDKOptionally of the other dependencies involvedIf possible, create a pull request with a (failing) test case demonstrating what's wrong. This makes the process for fixing bugs quicker & gets issues resolved sooner.Requesting a FeatureIf you wish to request the addition of a feature, please first check out theIssuespage and thePull requestspage (both Open and Closed tabs). If you decide to continue with the request, think of the merits of the feature to convince the project's developers, and provide as much detail and context as possible in the form of filing an issue on theIssuespage.Contributing CodeIf you wish to contribute to the repository in the form of patches, improvements, new features, etc., first scale the contribution. If it is a major development, like implementing a feature, it is recommended that you consult with the developers of the project before starting the development to avoid duplicating efforts. Once confirmed, you are welcome to submit your pull request.For new contributors, here is a quick guide:Fork the repository.Build the project using theDependenciesandTestssteps.Install avirtualenv.Develop your code and test the changes using theTestsandCode Qualitysteps.Commit your changes (ideally follow theAngular commit message guidelines).Push your fork and submit a pull request to the repository'smainbranch to propose your code.A good pull request:Is clear and concise.Works across all supported versions of Python. (3.7+)Follows the existing style of the code base (Flake8).Has comments included as needed.Includes a test case that demonstrates the previous flaw that now passes with the included patch, or demonstrates the newly added feature.Must include documentation for changing or adding any public APIs.Must be appropriately licensed (MIT License).Documentation ContributionsDocumentation improvements are always welcome. The documentation files live in thedocsdirectory of the repository and are written inreStructuredTextand useSphinxto create the full suite of documentation.When contributing documentation, please do your best to follow the style of the documentation files. This means a soft limit of 88 characters wide in your text files and a semi-formal, yet friendly and approachable, prose style. You can propose your improvements by submitting a pull request as explained above.Need more information on how to contribute?You can give thisguideread for more insight.LicenseThis software is licensed under the MIT license.
