How to send grin via v4 CLI wallet?

Tech Support
1

Could anyone give me a sample?

I tried v3 method send -m file -d my_grin_transaction.tx 10.1 got an error.

error: Found argument '10' which wasn't expected, or isn't valid in this context

USAGE:
    grin-wallet send --dest <dest> --manual

For more information try --help

m option is not method anymore but manually. Check grin-wallet help for more info.

Example below:

$ grin-wallet send -m 10

So, I’ve tried below.

Sender:

grin-wallet send -m 10

This created 8c4d6408-e16c-4e5f-9bae-0319dfc8f36e.S1.slatepack.

Receiver:

grin.wallet receive -m -i 8c4d6408-e16c-4e5f-9bae-0319dfc8f36e.S1.slatepack
Password: 
Wallet command failed: LibWallet Error: I/O error

Not sure if this helps or anything, maybe I dont understand at all, but https://github.com/mimblewimble/grin-wallet/issues/456 indicates that v4 slatepacks wont be live until after the fork, if you want to use them now you have to pass through a flag. Maybe -m makes v4 slates automatically but without the flag you cant receive it, no idea, but it is probably something about v4 slates vs others.

No issues on my side.

I notice that you are using the snap version on Ubuntu. Let me try this myself.

Are you sure you are inputing the full path of the slatepack? Doesn’t seems so in your example.

I tried on windows, it seems work.But this error persists on ubuntu, i installed by snap install grin.

grin.wallet finalize -i /home/oenenfe/14e457b7-2660-4103-9f54-cec131b23fad.S2.slatepack
Password: 
Wallet command failed: LibWallet Error: I/O error

I moved 14e457b7-2660-4103-9f54-cec131b23fad.S2.slatepack into /home/oenenfe/snap/grin/current/.grin/main/slatepack. then it workes. Thanks alot.

@quentinlesceller can I send grin by http/https on v4?
