Hi, is there an alternative to downloading the core wallet (150 GB of blockchain data and I dont have any free space) just for signing my semux wallet address?
Thank you.
Do you have the private keys of your bitcoin addresses?
You can import them into electrum and sign with that.
well, I just created my first btc address. When I try signing my semux wallet address it says:
Invalid bitcoin address
First of all, you need to choose a btc address as the one doing the signing too. Have you done that?
Second, if you just created it, there is no way it had any funds in it on block 480000 which is when the snapshot was taken. So you can't get any semux from the airdrop.
