OST Platform SDK for Ruby.
OST is a complete technology solution enabling mainstream businesses to easily launch blockchain based economies without requiring blockchain development.
Brand Tokens (BTs) are white-label cryptocurrency tokens with utility representations running on highly-scalable Ethereum-based utility blockchains, backed by value token (such as OST, USDC) staked on Ethereum mainnet. Within a business`s token economy, BTs can only be transferred to whitelisted user addresses. This ensures that they stay within the token economy.
The OST technology stack is designed to give businesses everything they need to integrate, test, and deploy BTs. Within the OST suite of products, developers can use OST Platform to create, test, and launch Brand Tokens.
OST APIs and server-side SDKs make it simple and easy for developers to integrate blockchain tokens into their apps.

- Sign-up on OST Platform and setup your Brand Token.
- Obtain your API Key and API Secret from developers page.
The preferred way to install the OST Ruby SDK is to use the RubyGems package manager for Ruby. Simply type the following into a terminal window:
gem install ost-sdk-ruby
