I've just found this section in the README:
which already clarifies a lot.
In my case, I am curious if I could build my JS code to WASM and then use this WASM on the MultiversX blockchain, which executes the WASM code using WASMER.
https://github.com/multiversx/mx-chain-vm-go
Because I want to run the WASM on a blockchain and that deploying code on the blockchain is very costly, I want the WASM size to be as low as possible.

I'm not familiar with various blockchain execution environments. The environment you're attempting to execute your Wasm module in would need to make a set of Javy imports available to the dynamically linked module. The javy-quickjs_provider
Wasm file exports functions to satisfy these imports but you would need whoever is managing the runtime you're deploying against to instantiate that module and make it available to link against. Wasmer out-of-the-box will not do that, it would have to be specially configured to do that by whoever is hosting the blockchain. My guess and assumption would be that they're not doing that so you would see a module instantiation failure because of unsatisfied imports.
Thank you very much @jeffcharles for your explanation which clarifies a lot the situation for me :pray: :pray:
What is your question?
In the README I see written:
If I build using dynamic linking, can I then run the .wasm by any WASM runner?
I think my question comes from the fact I don't understand properly what "dynamically linked" means.
Thank you very much for the time that will be taken to answer me :pray:
