Document ethers 4 and 5 Web3Provider incompatibility.

[eccentricexit]

Problem: web3-react project using ethers 4 cannot use a library depending on ethers 5 because the two versions of Web3Provider are incompatible.

Document this or provide a path to use an ethers 4 provider on ethers 5 so users don't have any surprises.

One of the main reasons we have major version changes is to allow us to break backwards-compatibility. It is not common to be able to use objects from one major version in another. This should not be surprising. :s

It depends a lot on what you are trying to do, but if you must, you could always wrap the provider in a Eip1193Bridge from v4 and then use the Web3Provider in v5 to wrap that. It is clunky, but might hold you over until the upstream dependencies catch up.

Honestly I don’t know what I was thinking when I opened this issue 😅. Perhaps lacking sleep

Thanks for the reply
