Here is a 2nd one I made......my time is 4pm and I placed a 7pm timelock....so 3 hours in the future  020000000156ca7e2bdb24ecc2fc1e7fc7a764edd3feeb7bb0702450fb3c471f57b8201de6000000006a47304402201fa31e2b081b05ae06273862b6b7a528565970d1b613a8420f27c05cde182d590220125ccf210c00e9f8e958d5b97649d5bc3d9ff9b960de9191771464c8144270b201210249cfee87a6f55d0bd9e2be09adc8b72e434789b87d53860d628df167eba00de1fdffffff01155d0000000000001976a914549c9f4f0f5911f080a8b6c1f3ec137afc8f823c88ac9789ff5f Decoded Transaction

Ok so I made a new locktime for 240pm EST as follows...  020000000156ca7e2bdb24ecc2fc1e7fc7a764edd3feeb7bb0702450fb3c471f57b8201de6000000006a47304402200714987225e63727f37d8b7c38ec9e1ab4079b234ef88e49d147c5663620d32f0220158a7aa47e1e0dd93501408658f064213c740930994e06feb9431024206bb6b901210249cfee87a6f55d0bd9e2be09adc8b72e434789b87d53860d628df167eba00de1fdffffff0155680000000000001976a914549c9f4f0f5911f080a8b6c1f3ec137afc8f823c88acad5aff5f Decode A Transaction

} I wanted to see if it would broadcast...and it did before the 10 minutes to broadcast arrived here https://live.blockcypher.com/btc/tx/7fde5a833eabc42b5f90d3a5a8015372e449d6749fa090c678a2f7746b76d007/ Funny thing,is I do not see it in my receiving wallet yet. Perhaps after 340pm est? I will try another one, but had to post this one..no idea what I am doing wrong..will give it a 30 min lead time this time. |
|
|
|
I just tried with a block number...and I am getting same issues. Why? The deposit I placed in Electrum wallet is unconfirmed....thats the only thing I can see that might be an issue..but I doubt it  |
|
|
|
Could it be it's too close to the end time?
LoyceV read this.
I tried again an hour later and still same results. I am using blockheight now as an experiment and see how that goes. But I want the time lock exact not guessing what the time might be. |
|
|
|
The electrum server you're sending it to wants a higher fee to be paid. Not sure why though since it says it's 2 sat per byte (maybe trying to. Help people not get transactions stuck with a custom script on that specific node).
Ok..but why am I getting errors on the websites? I am trying to broadcast it on btc.com and also on blockchain.com Edit..whoever gets this in the future should be able to transmit anywhere thats why I am trying outside sources |
|
|
|
Ok. I made an Electrum nLocktime transaction for a certain date in the future instead of block heoight.....yet when the time came and past I was not able to broadcast on Electrum or on a blockchain website. Can someone please let me know what exactly is the issue? Thanks I made a transaction timelock for the 11th January 2011 222pm  I used the following website to decode...it was the only one able to https://btc.com/tools/tx/decode  I tried the same on https://www.blockchain.com/btc/decode-tx And I got this error  SO when the time came and went past the broadcast..I tried and these are the results. On btc.com  On blockchain.com Code: -26, Error: non-final and this on electrum itself  |

Took out papers and scanned. Also took pic for the record all laying next to each other. As you can see, Terra slate paper, Revlar and Ritnrain's Duracopy are in perfect condition...all scanned and are intact Ritneintherain all weather paper is soggy and yellowing a bit on the edges, but it still in good shape to read the qr codes. The regular ink I used to mark Terra slate is also intact. Paper out for less than a minute and all were immersed back in the water right away  |

One other site I found that was helpful in trasmitting the raw TX was https://bitaccelerate.com/pushtx/ PushTX - Broadcast Raw Bitcoin Transaction
With this tool, you can anonymously broadcast your transaction over the Bitcoin network. To do this, enter the raw transaction HEX in the form above and press the button. The service will send the transaction to our Bitcoin node, which is connected to over 100 other Bitcoin nodes at any time.
This way, your transaction will spread as fast as possible across all Bitcoin nodes. This will keep your anonymity because the transaction goes out of our node. We do not keep any information about the transactions we broadcast, nor about the users of this page. You can rest assured.
This service is using the "sendrawtransaction" method of the Bitcoin Core client. Your transaction must be signed and must not contain unconfirmed inputs. So when you have the signed transaction back on the live electrum, instead of broadcasting thru electrum, I copied and pasted it on the site. |

I don't have any of these water proof papers, so what I've been doing is painting or brushing my normal paper laser print outs with some white glue (elmer's glue.) The intent is to cover the paper in transparent epoxy resin after the white glue is dry. That makes it hard too (some 9500 psi hard or something). It's not fireproof at that point but that's what a safe is for. https://www.youtube.com/watch?v=lxL59BgzNPYThis is a video of paper permanently encased in transparent epoxy resin. Just replace the dollar bills with your paper wallet. I did the resin test with some QR codes as seen in this photo...then placed in my aquarium. What better place to protect my paper wallet than at the bottom of my shark tank!   What I did have to do is laminate the QR code first then pour the resin, which heats up quite a bit. And I recommend doing it outdoors as the fumes can be quite strong. |

Again for anyone who still loves the idea of paper wallets, I am conducting a test on these water proof papers. Its been almost a month now for some submersed under water, and they have passed with flying colors! I do recommend to use any of them or similar material if you make any. The worries of water will be eliminated some or completely! https://bitcointalk.org/index.php?topic=5296179.msg55742293#msg55742293 |

thanks for this - I am going to start using this paper for all the ones I generate for the chips I sell and/or fund.
PM me your address I'll send you a few sheets of revlar to play with. Since it is hard and thick (heh heh heh he said it's hard and think) it might not be the easiest to get under the holograms of coins and such. Much like the ones I sent to krogoth they are not white matched since most of them come from different batches. Doing stuff like this it does not matter, but for archival contracts that fill binders it's noticeable. Different shades of white paper, 20 years ago I never would have thought that would be an issue in my life. -Dave Using yours and the others with no issue whatsoever. I actually am printing the private key twice in two different formats, I am placing the keys on one paper and then printing the QR code on the other.Its more time consuming for me but I feel its worth it. This way when people are using whatever wallet to redeem, they will have the option of either placing the keys one by one, or scanning via QR code. And at the same time its waterproof so no worries about a flood.  |

 Scanned all submersed paper wallets just fine. Almost a month under water for the starter one. Added Duracopy with the rest. So now we have RitenRain, Duracopy, Revlar and TerraSLate. Changed the water and filled to the top. For people who have paper wallets and are interested sweeping with private keys offline first then broadcasting raw transaction without ever exposing the private keys this article should be of interested to you. One member showed interest and I made a thread on it using an air gapped cell phone with a hot cell phone and also if preferring a laptop along an air gapped cell both using Electrum. https://bitcointalk.org/index.php?topic=5303860.msg55941150#msg55941150 Remember there is always a chance you can sweep a paper wallet using a hot wallet and if malware or a virus is present they can sweep your keys before you can. This method can eliminate that possibility and you will have a chance to double check the transmission amount and btc addy it is going to. |

Will give to all tomorrow...and one computer is brand new dell..so as clean as they come I hope.
Just make sure that Procmon is capturing events before you start Electrum, or it's going to miss some at the beginning. You would not believe what was causing the error. First I bought and installed procman, but before I used it , I tried electrum again, and I noticed instead of going to load transaction I click on sign verify message instead of load a transaction...I guess my brain was a bit fried at that point. Anyway, so today I continued and just briefly did a succesful transaction which I tried again to replicate and post in here step by ste with pics. Well guess what, at the end at exactly the part where I want to load a transaction with a QR code, to my horror this error came up.  AHHHHHH!!! Then I have no idea why I thought about it, I realized my electrical tape was still covering my camera ( YES I cover my camera), I restarted electrum and this time it worked like a charm!!! You can see the step by step between Laptop and air gapped phone here https://bitcointalk.org/index.php?topic=5303860.msg55941154#msg55941154 |

THIS OFFLINE WALLET SWEEP WILL BE USING AN AIR GAPPED PHONE AND A PC ELECTRUM. Again create the same steps you did with the air gapped wallet as we did in the example above. Next for the hot wallet on the PC, install Electrum....  STEP 1 NAME YOUR WALLET STEP 2 CREATE NEW WALLET...SELECT IMPORT BITCOIN ADDRESS On the hot live PC wallet, we will be importing the public address ONLY STEP 3 Click on camera tab and scan in front of pc camera the Public address part of your paper wallet. HIDE THE PRIVATE WALLET, MAKE SURE NOT TO EXPOSE IT TO CAMERA!! As you notice, if bitcoin word is in front of the address then you need to delete the word otherwise the next button will be greyed out. STEP 4 Once the public address is on their click on next, a password option is given, if you want to add you can otherwise hit next.  STEP 5 Watch only wallet created meaning the paper wallet public address is on the electrum with no private key which is EXACTLY WHAT YOU WANT! Click OK and the click on the send tab STEP 6 Click on camera tab on the pay to box, this will activate your computer camera. SCAN the QR code for the public address you want to send all the funds from your paper wallet to. Then click on MAX on the amount line. You should see the full amount of the balance minus miner fees in this box. Then click PAY STEP 7 You can see you have an unsigned transaction in the highlighted box top left. Also I adjusted the miners fee down to 2 sats in the middle highlighted box. In the outputs boxe, you can find the public address where the funds will be sent to. SO double check to confirm it is correct, with the amount to be sent as well. Click FINALIZE STEP 8 You now have an UNSIGNED transaction ready to be signed on your air gapped phone. Click on export and then show as QR code. Once the QR raw transaction pops up, scan with you are gapped wallet and the following will come on the screen...  STEP 9 The unsigned transaction scanned into your air gapped phone will be shown. Click SIGN STEP 10 Confirm signing transaction...Click OK STEP 11 You can now see on top it says signed and also the transaction ID is shown as well. This is ready to be broadcast as the button is available as well, but since this is an air gapped phone you cannot, so we need to click on the QR code and take back to the live wallet on the PC. Also you can double check amount and pub address where the funds are to be sent to to confirm nothing has changed!!  STEP 12 On laptop Electrum, On top where the tools tab is click on load transaction and then select QR code. This will activate camera, the scan the QR code raw transaction from your air gapped phone. STEP 13 You will see the identical information you have in your air gapped phone come up. Again double check to confirm all is correct! Once ready, click broadcast and your raw transaction has been sent to the blockchain! The payment sent TX id will pop up as well! Hope this helped you all, any questions ask!! To recap...  |

One of my most favorite ways of storing bitcoin is on a paper wallet. Paper wallets if done right are one of the most secure ways of storing bitcoin especially if done on an air gapped computer which in my opinion is a must. The tricky part is when the time comes to sweep the wallet and that is where screwups can happen. If your computer or phone has a malware or virus infecting it, then chances are you can lose your bitcoin. One way to prevent this from happening is to never expose your private key to a hot wallet or the internet, but rather have it signed using an airgapped device with a wallet on it. We will be using Electrum and to make sure you have the right Electrum, you can read about it on this thread I wrote on another way of siging a BTC transaction where people brought up ways to make sure your electrum download is not tainted in anyway. https://bitcointalk.org/index.php?topic=5106013.0 www.electrum.org I will use cell air gapped cold wallet to cell hot wallet So in this setup we will have a cellphone and a computer both installed with the latest version of Electrum. These are the steps I took.... Wipe out all data on cellphone and have it reboot with factory reset, thus cleaning it of any malware or viruses. Install Electrum and then place it in Airplane mode, disable wifi, disable bluetooth, remove sim card and also remove the antenna thus making it air gapped. Creating new wallet as follows.....  Click NEXT then name your wallet  Next create new password  The select type of wallet you are creating..in our case we are importing a public or private key. So up to this point you can use for both the air gapped and live hot phone electrums. Click on the camera tab to scan the qr code.  Here I will be importing the private key for the air gapped wallet phone  You can do the same for the HOT LIVE Cell phone wallet, BUT, ONLY IMPORT THE PUBLIC KEY! On the air gapped phone the OFFLINE will show as there is no connection with any internet signal. Thats exaclty what we want to see.  When clicking receive on both phones, and then request, the public address matching THAT particular private key will show. The Air gapped and the Hot phone Public addresses should both match!   On the HOW LIVE phone, click click scan and scan qr code of public address you want to send the paper wallet funds to Then Click amount and send MAX. Always sweep a paper wallet fully!   You can set the mining fees on the app, Change the method to "Static", you will be able to set the transaction fee to lower amounts. Look at the image below. The fee is only 1 sat/byte.  Next click PAY and the following information will show. Here you can check amount of BTC sent, mining fee and most importantly BTC address where bitcoin is being sent to.  Next click on QR tab and the following RAW UNISGNED TRANSACTION QR code comes up.  Now with your air gapped phone click on SCAN and scan the QR code from your live phone. This will take your raw unsigned transaction into your cold air gapped phone with the private key to be able to be signed! This is what will show on your air gapped phone after scanning the QR code from the LIVE HOT phone wallet.  Next click on the sign TAB and the following will come up confirming you want to sign the unsigned transaction.  Once you click on yes, the new window coming up will show you a signed BTC transaction with the address the btc is going to also the amount! This way you can be sure the btc is going to the BTC address you want it to goto and not some malware altered BTC address!! Also the TX data is also present and showing.  Now for the final steps of transferring this to your hot phone by clicking on the QR tab on the air gapped phone which will produce a QR code. Take your live HOT Wallet phone and click on Scan, then scan the QR code from the Air gapped wallet. The following will show up, and again you can confirm and the information. Once you are satisfied, click on Broadcast and the raw transaction will be broadcast on blockchain and the bitcoin will be transferred from your paper wallet to the BTC addy of your choice.  I hope this helps people understanding how a paper wallet can be swept without ever having to expose the private keys to a HOT wallet. Again test with a very small amount of BTC until you have it nailed down and feel comfortable in doing this. Made another visual aid to make it even easier to understand. |

Thanks for your input on how you sweep the BTC then the forks afterwards once the most important BTC is swept and secured first! Can you or anyone else in here let me know their thoughts on that very risk you describe above regarding it's just a race to get your BTC off your phone and onto a HW wallet? I mean let's say I use Ballet or Coinomi what are the actual risks vs doing it the way you described above? I have no doubt your way is likely more secure but for any security experts in here how much more secure would that way be?
PS: Also at this very movement in time I'd have to go with Coinomi for the BTC as they allow you to set the fees and I'd obviously set them higher for the need for speed but even Coinomi's faster fees is much cheaper than Ballets one size/speed fits all unless they have updated this in their software allowing for us the owner of the Ballet cards to select which fees and how much speed we need a sweep done. Because I do feel Ballet would be more secure given the fact it's a more colder of a wallet than Coinomi just being a straight up hot wallet(a great one but still a hot wallet nonetheless). Would love any and all thoughts!
PS: Thanks for video Krogoth....will watch that soon as I want to learn as many ways as possible!

The race against time he refers to is as follows... If for some reason you have a virus or malware specifically engineered to be able to copy your mnemonic or paper wallet...or and private key...then they can literally beat you to sweeping your coins before you do. So why take that chance when you can sign it safely offline first? Especially with a 10btc coin. Better safe than sorry There are also malwares that send your btc to a different address...they switch the addy at the end. https://www.zdnet.com/article/innfirat-malware-lurks-in-your-machine-to-steal-cryptocurrency-wallet-data/ https://www.coindesk.com/malware-miners-torrents-passwords Here is a thread of a different way to carry any btc you plan on sending without actually having the btc on your hot wallet. I used to use this method when i met people in person and didnt want to carry the btc on my Mycelium wallet https://bitcointalk.org/index.php?topic=5106013.0 Also make sure you download the real clean Electrum https://coingeek.com/hackers-steal-over-22-million-via-electrum-wallet/ |

I tried to import/sweep a casascius on the ballet wallet app it didn't work for me. Exodus worked for me for the btc then I used coinomi to claim the forks
Coinomi as well here for forked coins...then to exchange to btc as well. |
