Hey,

I have a set of scripts for composing & executing contract transactions via contract.tx.method. But my current contract is governed by a multisig, which means certain tx's need to be performed on behalf of that. I know how to initiate & approve multisig tx's in polkadot-js/apps – but not withinapi/api-contract.

My idea was to (a) initiate it in my scripts as I usually would, export the call data (as hex or bytes), and use this to (b) approve it in polkadot-js/apps (doesn't need to happen within the script). But I neither know how to do (a) on behalf of a multisig nor do I know (b) how to export the call data.

It would be awesome to get some help on this, @jacogr.

Sorry for the late response, I guess this slipped though the list of Issues. @Thongnguyentam if you are looking to do it as wottpal suggested the key would be to get the SCALE encoded data and then sign it with a multisig.

I don't have a smart contract at hand to test this but I would assume that by doing

let encodedCall = contract.tx.yourMethod().unwrap().toHex()

Should return the encoded call that you can then put into the Decode tab on polkadot-js/apps and then sign with the multisig.

You should also be able to do it through the api but if you can't please feel free to provide more context or a way to replicate it so that I can test it and provide more info
