Thank you for your medium post and this repo.
I've noticed that your transactions are wrongly signed in case there are more than 1 input. Problematic line of code is this:

txb.sign(0, key);

That line is signing only the first (zero index) input, but it should iterate over all inputs and sign with their corresponding index. The same thing is wrong in the medium post.

hi

in ubuntu, npm run start
cannot start the app.

node: v10.15.1
os: Linux Mint 19.1 Tessa 64bit

I'm getting the following error PropertyTypeError {message: "Expected property "1" of type Satoshi, got Number -869423492"

I have just forked your repo and after npm install, I started project which runs correctly. But when I create an address it gives me this error....surfing internet but not got the solution yet
