the only way to make this work on polkadot.js.org/apps is to run chopsticks on background, otherwise this is unusable

@ermalkaleci you mean the wasm execution will freeze UI by blocking the main therad? in that case yeah we need a web worker

yes

[ermalkaleci]

I think ChopsticksProvider can start a web worker that contains blockchain setup and use post message for rpc calls

Yea when I was trying to test tx and it keeps hanging, so I need to setup chain in a web worker

Todo in future: node.js compatibility, issue: https://github.com/AcalaNetwork/chopsticks/issues/446
