-This hardware cosigner allows to securize your funds by being a required device for a multisig wallet. Once set up and connected to internet via Wifi, you can pair it with the standard Byteball GUI wallet, add it as cosigner for a multidevice wallet then authorize the signature of a transaction from a webpage accessible from your local network. 
-It works on ESP8266 and ESP32 boards but ESP32 is recommended since it has no practical limitation about the size of unit you can cosign.
