What I do not understand is, I gave them my pub key and they then gave me a script..>What exactly do I do with that? I cannot broadcast it at all.
they give you a redeem script that you need for signing the transaction later.
they also give you an address (starting with 3) that you can use to send coins to (make sure you test it first before sending coins).
So what are the next steps? I sweep the private key once say 4 pm is reached and automatically the signature key pub adddress is loaded?
you can't sweep this key in any wallet that i know of because they don't support custom scripts like this one.
you have to create the transaction using the same tool and sign it there also.
go to the Transaction page the enter your redeem script there and fill in other boxes to spend the balance of that address you created above (the one starting with 3) to a new address.
then use the result in the Sign page with your private key to sign this transaction.
finally broadcast it to the network
Also how do I see the Hodl key on blockchain to see that is timelocked? I know I can see the balance, but what is telling me that it is timelocked for the time I gave it?
there is no way to know the type or the script that was used to create P2SH addresses except for when they are being spent. so with only having a balance in that address you can not verify if it is time-locked on the blockchain. you can only see your own redeem script and based on that manually verify that it is a OP_HODL.
