aleph-sdk-ts

Description

This SDK offers binding to interact with the Aleph decentralized network.

Written in TypeScript, it's designed to replace the aleph-js library and works seamlessly in the browser, on Node.js servers, and within the Aleph Virtual Machine without internet access (using socat).

Quick Start

Installation

To get started, install the SDK using npm install <package>. Available packages are:

# Legacy (3.9.2)

@aleph-sdk/client
@aleph-sdk/message
@aleph-sdk/dns
## EVM chains
@aleph-sdk/evm
@aleph-sdk/ethereum
@aleph-sdk/ethereum-ledger
@aleph-sdk/avalanche
@aleph-sdk/base
@aleph-sdk/superfluid

Additional Resources

• API reference: Detailed documentation for the SDK's API.
• Aleph TS SDK Gitbook: Guides and use-cases for the SDK.
• Examples: Sample code snippets demonstrating the SDK's usage.

Supported chains

This is the list of currently supported Account types. For each of them you can:

• Retrieve an account from a private key or mnemonic (or generate one on the fly).
• Sign and send messages on the Aleph Network.
• Some allow you to retrieve an account from a browser based wallet (ex: Metamask), or from a Ledger wallet.

Previous versions of the Typescript SDK allowed you to encrypt messages.

Environments

Supported Node.js Versions

Version	Supported
v14.x	✔️ Full working support
v16.x	✔️ Full working support
v18.x	❌ Some feature may not work (see notes)
v20.x	✔️ Full working support
v22.x	✔️ Full working support

* Due to changes in OpenSSL in Node v18, some chains helper may not work. If you encounter bugs using Node v18, you might want to consider using the --openssl-legacy-provider feature flag while running your project.

Running code inside the browser

This SDK relies on several non-native browser modules (such as Streams and Buffer). While bundling your application, either using rollup (ex: Vite) or webpack (ex: create-react-app) you might have to rely on external polyfills for those features.

You can check the configuration files from the examples/toolshed directory to get started. Please note that we won't provide polyfills as part of this SDK.
