Polkadot integration C++ API for Substrate allows to read chain information and state, block details, as well as sign and publish transactions in C++. It also allows to subscribe to substrate node websocket endpoints and receive data updates.
POC is available here: https://github.com/usetech-llc/polkadot_api_cpp
While high quality well documented APIs help community integrate with products in general, C++ API will be especially helpful for financial sector as well as gaming industry. Financial companies are looking more and more towards crypto markets, and gaming assets become tokenized in the form of miscellaneous types of tokens, frequently cross-chain. Because of their high performance requirements, both industries historically accumulated large code bases in C++, so this API aims to greatly facilitate adoption of Polkadot for them.
Substrate provides secure WebSocket endpoints, which are used directly by C++ API.
We see Polkadot as a very promissing technology that will be used for a large number of use cases. It will greatly contribute to adoption of blockchain in powerful applications. It is technically one of the most ambitious blockchain projects we know of, and we would like to be part of the community that's creating it, as well as developing on it once the network goes live. This proposal is just the first step in creating what we hope will be a large Polkadot team.

Our team memebers each have more then 15 years of IT experience in managing projects and writing software for product companies and large enterprises alike. We created the Blockchain practice in 2016 and have done dozens of projects for clients accross the globe on variety of blochchains, mostly on Ethereum.

Project roadmap and financial plan will be shared privately via Google Form.
Long term plans start with developing APIs for all mainstream languages as well as in-depth API improvement. As Polkadot community high level usecases evolve, API will adapt.
Also, our team plans to implement broader spectrum of applications such as
- Decentralized Non-Fungible Token Exchange
- Multi-chain token issuance
- Cross-chain Payment Gateways
- etc.
Proof of concept C++ API has been done, which successfully establishes connection to a public substrate node and retrieves a JSON string for method chain_getRuntimeVersion. Source code and preliminary documentation is available at this public repository: https://github.com/usetech-llc/polkadot_api_cpp
So far there has only been JavaScript API project: https://polkadot.js.org/api/
Other mainstream languages are not yet covered. Our plan is to start with C++ and cover all mainstream languages/stacks such as Python, C#, Java, etc. We believe that having a wide coverage will greatly improve adoption of Polkadot among the software developers.
