shorthand:

const machine = {
  model,
  make,
  vin,
  address: result.logs[0].args.newMachine
};

this function does not return anything. I would suggest returning a value when defining functions.

[michalmikolajczyk]

const { state } = this;

[michalmikolajczyk]

onSubmit={this.ownerFormSubmittedHandler}

[michalmikolajczyk]

you would need to bind it to this in the constructor first. Add to the constructor something like:

this.ownerFormSubmittedHandler = this.ownerFormSubmittedHandler.bind(this);

for all functions that refer to this, obviously. That is very handy when passing the functions to child components.

[michalmikolajczyk]

you refer to this.state more than once, it would be worth it to deconstruct it at the top of the function

const { state } = this;

or

const { forms, contracts } = this.state;

Awesome!

Basically the work looks really cool!

1. I would suggest we refer to Airbnb style guide https://github.com/airbnb/javascript for both JS and React. I will add an eslint file.
2. I am not sure if we should load the full ui-kit package. We don't need the rtl file, and I don't really see us modifying the package – perhaps the minified files would suffice?
3. we need to have proper unit test coverage of all files with business logic

[michalmikolajczyk]

in fact, can we use ui kit from npm?

[michalmikolajczyk]

I applied another commit, now we use ui kit from npm.
