Hi there, thanks for reporting. This program isn't meant to support a web assembly build at the moment, but maybe we can still provide something helpful with not too much work. What are you trying to do?

Can you provide more information? We likely won't go through the work of getting the whole crate WASM-friendly, because it's a Solana on-chain program, but we can probably extract whatever you might need into an "interface" crate, similar to https://github.com/solana-program/system/tree/main/interface.

Specifically, what do you need from the spl-token-2022 crate?

[Katletos]

Just need constants, that represents program_id. Also unpack method.
It's probably doesn't make any sense to split the project. I needed 3 programmes, so i just hardcoded them. As i recall, the unpack method worked

[joncinque]

Gotcha, we could certainly factor out the instruction and state logic into an "interface" crate, since token-2022 otherwise has a lot of heavy dependencies.

If you have a workaround though, this might be a lower priority

[joncinque]

We split out the interface with #616, and now test that wasm builds work for both the program and interface, so this should be resolved. Please create a new issue if you're still running into problems
