I had a transaction with a vendor on traderoute before the exit scam. I was able to get in contact with the vendor, provide him the with the redeem script. Now he's telling me, I need to sign the key to release the funds and he will ship out my stuff.
I tried signing on coinb.in but there was a unlabelled textblock and I had no clue what went into it. I really have no clue what I need to do for him. can anyone help me out?
if you sign it before you receive it, then you just give him the funds. This is no different than FE'ing through multisign or doing a DD.
Tell him you'll sign after you get your pack.
