Wallet creation speed not improved 💭

[alimurad-1]

Question

How do I optimize the speed of wallet creation, I have followed the library guide but wallet creation is still taking 15 to 20 seconds

I am missing some configuration steps but I am unable to figure out the app performance is compromised and I want to improve it

any help with this issue is appreciated

Does it help to use RNQC polyfills? (see README.md)

import { install } from 'react-native-quick-crypto';
install();

I'm not sure what ethers is doing internally. What RNQC calls is it making? Are they supported in the implementation-coverage.md doc?

Maybe create a small public repo that reproduces this issue so it's easier to test?

So I tried to create a public repo to with a fresh react native project, but it is giving build error in android

and upon looking at issues page I get to know that I am not the only one facing this issue

[alimurad-1]

the following setup helped me achieve the required speed

https://github.com/ethers-io/ethers.js/issues/2250#issuecomment-1599169934

this setup is for the ethers v6

however the RNQC issue with new react native versions still persists

[boorad]

if new RN versions are still having issues, please reopen an issue for those separately.
