@xiaojay Hello, and thank you for your contribution of the GRIN GUI. I was using the wallet713 and this helped me a lot especially with the hedwig implementation.

I have a problem, I withdrew GRIn from Kucoin to the Niffler wallet and the transaction has been stuck in unconfirmed state for couple of hours. The first GRIN I sent to the hedwig address arrived instant and the next transfer to the same hedwig address shows this problem I have provided a screenshot as well. I have tried using the check balance feature many times and this doesn’t do anything. My last option is to cancel the transaction but I am afraid that it will loose the GRIN.

Your help is highly appreciated,
Thanks.

Just cancel it, you wouldn´t lose Grin because it´s unconfirmed.
The Grin will stay in exchange and then you can repeat the transaction.

12

Try to contact kucoin.
I think it’s their problem: they could not broadcast the transaction to blockchain.

and what @debilnypes said is right. The grin was still in exchange.

13

Thanks, I cancelled it.

14

Yes, I contacted them and they resent it, 3 times actually before it finally came as confirmed. Thank you.

Wow thanks to whoever made this. My grin were stuck in grinpurse. I finally got around to getting niffler going and was surprised that it was able to import my grinpurse balance without me having to go through the recovery seed entry process. Very nice, thanks.

Edit: when I run niffler, am I running a grin node?

16
  1. yes, Niffler use grin official cli wallet in the backend. so it could recognize your existed wallet.
  2. No, right now Niffler use a public grin node I built. I will add options to let user run their own’s grin node in next next version of Niffler.
