@mindrunner can you fix the linter issues and write a few integration tests that cover the new code?

[mindrunner]

yeap, already on it. didn't find the time yet

[mindrunner]

Looking at the tests, it seems like comparing my tx with cli_wire_msg would not work. (And it does not indeed.)

Where does js_wire_msg come from. Was that generated by solana-web3.js?

Yes

@mindrunner i'm trying to incorporate your code, but am having an issue when trying to use create_account_and_delegate_stake. It seems i need to provide a stake account, even though the function is supposed to create one. Thanks

[mindrunner]

Are you refering to stake_pubkey parameter?

Just generate a keypair and pass in the public part and you should be fine! :)

[Morgandri1]

Does it not require an owner? When you create a token account it has to be attached to an owner, so I would assume this would be the same or a similar system.

[mindrunner]

As far as I know, those kind of accounts do not have an ownership of that kind. You provide an authorized keypair instead. This private key will be the one having the stake in custody.

I think the Solana Stackexchange would probably be the better place to ask such questions :)
