Creating open source libraries to integrate blockchain tokens with IoT to bring the benefits and flexibility of token integration.

My libraries are:

Web3E - similar to Web3j but running on ESP32. Highly optimised and minimal library which can send transactions, query smart contracts, communicate with web apps and tokens using TokenScript powered devices.

AugustESP32: library for communicating with the August smart lock family of devices. Using Bluetooth with these devices brings you much improved security, and combined with Web3E gives you effectively ECDSA authentication and benefits of token integration for operating your door.

Using the two libraries together you can create your own home/rental management contracts which are fully integrated from purchase (in cryptocurrency) through to access control and service integration.
