AppInventor aims to make coding accessible to all by providing a graphical API to develop Android applications through high level components usually referred to by “blocks” (by Blockly). It comes from Google, then MIT, and is open source. The strength of AppInventor lies in its simplicity and ergonomics : kids can learn to build an app in a few hours, and business professionals can as easily construct a proof-of-concept of their ideas. Ethereum and public blockchains in general must be accessible to anyone, we are now making blockchain programming accessible to anyone with an AppInventor extension: Qaxh.Eth. With basic blocks such as connecting to Infura, "getBalance", “signTX”, "sendTx" or "getTxStatus" anyone can now create his own app to interact with Ethereum. I will show how I have added extensions based on web3j in order to create blocks for accessing the blockchain. The lightning talk will quickly present the technology, a workshop whose agenda is on another submission will have participants make their own mobile app and create more appinventor blocks, either borrowing functionality from web3j or fully making their own.
