In this demo video our colleague Emmanuel introduces the Filecoin Virtual Machine Client Tool created under the frame of the FVM Assemblyscript SDK. This project is meant to be used as a client library to interact with your smart contracts. You will be able to install, instantiate and invoke methods of your smart contract. This is a JS package you can import easily in your project. Further documentation can be found here https://docs.zondax.ch/filecoin-virtual-machine/client/
