I got the same errors when i tried to use my original keys.
So now i have two addresses. Please provide a way to send money from
the first one to the second one or to unify them somehow.
The keys generated via the airdrop and the webwallet use the exact same code. As long as you have a 25 mnenomic keyphrase provided from the airdrop dashboard, you will have access to your airdrop funds (and mining funds if you pointed your miners towards said address).
For those running into any errors logging in, I would recommend trying a different browser (Firefox, or worse case scenario: Chrome)
Regarding the sweeping, yes - we will need to add a
sweep_all function to the webwallet for those with significant amounts of UPX. We may also use
transfer_split. As for now, you will have to send multiple smaller transactions instead of singular transactions > 100K UPX.
