It can't build to wasm

[aewc]

When I use this dependency in my wasm project, it will report error when compiling:

error: the wasm32-unknown-unknown target is not supported by default, you may need to enable the "js" feature. For more information see: https://docs.rs/getrandom/#webassembly-support

error: could not compile `getrandom` due to 2 previous errors

is there any features that without using the getrandom?

Same. It can still be reproduced in 2023.

You need to add getrandom with the feature flag of JS. This is not libsecp256k1, but its dependency rand which depends on getrandom.
https://docs.rs/getrandom/latest/getrandom/#webassembly-support

getrandom = { version = "0.2", features = ["js"]}

Fixed by upgrading Substrate to polkadot-v0.9.43.

This issue may also be related to cargo workspace dependencies. I suspect there was a potential bug when handling the individual default-feature = false.
