Thank you so much for the very detailed answer. This is great 👍 I'll use the implementation you suggested for U256 and wait for `datetime` to be released. Thank you!

Closing since 0.11.1 has been released! Thank you.

> It should be noted in docs, I agree and will close the issue after adding it. I'm also interested. Code example would be super nice.

@loyd There's convenient [U256](https://docs.rs/ethers-core/latest/ethers_core/types/struct.U256.html) and [I256](https://docs.rs/ethers-core/latest/ethers_core/types/struct.I256.html) here btw.

@loyd You're right, it is much bigger. If not integrate these types into this lib, any advise on how to use outside of the lib?
