Describe the bug

I try todo an erc20 token transfer with target wasm32-unknown-unknown. contract total supply as well as contract balance of works perfect. but as soon as i call contract.transfer("to_adress", "token_amount).from("my_address").send().await

i got the following error message in the browser console:

panicked at /home/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/alloy-transport-0.2.0/src/utils.rs:56:9:
The 'wasm-bindgen' feature must be enabled

I have already added wasm bindgen to the future list in my Cargo.toml, but this changed nothing:

alloy = { version = "0.2", features = ["providers", "sol-types", "json", "contract", "wasm-bindgen"] }

Can you try enabling "transports" feature too?

Can you try enabling "transports" feature too?

sure than i got this at exactly the same line within the code

I'm having the same problem.. Did someone find a fix for this?

I think it is caused by Alloy using std::time instead of something like https://github.com/daxpedda/web-time . std::time is not WASM compatible.

I ran into the same trouble with alloy. I have been using the wasm-bindgen feature, but that wasn't enough.

I have made a fork with patches that seem to work for me: https://github.com/b-zee/alloy/tree/fix-wasm-instant

See the patch here (it's unfortunately based on the 0.2.1 we depend on): https://github.com/alloy-rs/alloy/compare/v0.2.1...b-zee:alloy:fix-wasm-instant

Essentially it's a patch changing to depend on wasmtimer in the places I encountered a runtime error, e.g.:

#[cfg(target_arch = "wasm32")]
use wasmtimer::{std::Instant, tokio::sleep_until};

@DaniPopes, do you think the above is suitable for a PR? We'd love to publish a package soon and it would be awesome if the patch can be included in a future release of alloy.

[DaniPopes]

Sure, feel free!

Great, I've put in a PR: https://github.com/alloy-rs/alloy/pull/1426
