Overview

Software Development Kit to integrate in your back end applications.

Liminal provides a simple and robust client SDK to integrate digital asset wallets with your application. Liminal SDK is used in your back-end applications to communicate with the Liminal platform to create and sign transactions securely. Depending on digital asset and wallet configuration, it allows you to access various HSM devices from your infrastructure.

Software Development Kit

SDK will help you to interact with multiple digital assets over a single robust interface. Several sensitive operations, such as signing transactions and status, are always done at the client-side.

We provide and recommend the use of our Software Development Kit (SDK), which implements these client-side wallet features and interfaces with our APIs.

Currently, our SDK is available in JavaScript & Typescript and runs using Node.js. Please make sure you are running at least a greater version of Node 14 (LTS release is recommended) and the npm version must be greater than 6.

Authentication

Once you have on boarded on Liminal, you will receive client_id and client_secret as part of concierge on boarding. You must initialise your SDK integration with client_id and client_secret.

Environments

Liminal has two separate environments available for development and production. For security reasons, all Liminal API requests are made using TLS over HTTPS.

Test Environment
The Liminal test environment is used by default in our examples and the SDK. It is entirely separate from Liminals's production environment and there is no overlap in either data or accounts. Once you have on boarded, you will get access to our test environment and credentials to access SDK and API.

Liminal Test Site: https://dev.lmnl.app/
Test Environment API: https://api.lmnl.dev

Production Environment
The Liminal production endpoint is live and used by production applications. This environment is connected to mainnet networks of various digital assets we support.

Production Site: https://vaults.lmnl.app/
Production API: https://api.lmnl.app

Digital Asset Support

Liminal supports various digital assets protocols and assets on those protocols. We are continuously working to support more digital assets on our platform if they support securely with multi signature transactions and hardware security module ( HSM ) signing.
