Heho again! Thanks for building web3x!

When installing web3x on a Node.js 8 LTS system, I get the error

because the dependency bigint-buffer requires Node.js 10+.

Looking at the web3x code it seams that native bigint is also required. This limits the JS environments in which this library can be used to a few cutting edge engines. Would it be possible to use bn.js instead to make this work with Node.js 8 as well? In any case, I think the supported JS environments should be documented.

@webmaster128 I've posted consideration of this issue in https://github.com/xf00f/web3x/issues/36

web3x-evm is now it's own package, meaning web3x should run standalone on Node 8.
