Using ethers v5 providers in ethers v4?

[SilentCicero]

Hi all/Richard,

I want to use the ethers v5 provider but with some of my V4 arch, is this possible without causing to many issues?

They are not compatible with each other. You could possible try converting a v5 provider into an Eip1193Provider (in the experimental package) and then pass that into a v4 Provider to get a v4 provider.

But I generally do not recommend mix-and-matching major versions of ethers. I don't think most libraries support this, and it would be quite hard to keep everything forwards/backwards compatible...
