Title: Recover BTC Post by: ibreathepoker on July 30, 2023, 02:12:04 PM Hello everyone I'm new here and i have a question, i've send btc to my wallet on an app (lunu) and it didn't arrive so this is the message they send me:
Dear Customer, The problem is that you have used a decommissioned app, as you mentioned in the beginning of our conversation. We never got the amount you have transferred. We would like to advise you to export the raw key with your Lunu wallet konfigurations to get a possibility to forward your amount back to your personal wallet. Kind regards And they also told me to import my private key in raw format but that's not working anywhere maybe someone can help me out Title: Re: Recover BTC Post by: Zaguru12 on July 30, 2023, 02:21:47 PM I have never used a Lunu wallet/app so my answer will be on a general basis
Bitcoin transaction he no reverse except after it stays in the mempool for a certain period of time due to congestion and low transaction fee set. So when sending was there a transaction ID if there is then you can post it here for members to look into it for you. Also if the wallet/app has a private key then you can import them on any multi currency wallet supported by the wallet or app, maybe you should try trustwallet Title: Re: Recover BTC Post by: LoyceV on July 30, 2023, 02:37:29 PM We would like to advise you to export the raw key with your Lunu wallet konfigurations Can you do this? If you get a private key like this, you can import it into another wallet:Bitcoin private keys (don't post your private key here!)Example: L41YPdADy46J9Vh77WGR2bktFwEZ6knza2Xim3Urq9CEWynkkLgn And they also told me to import my private key in raw format but that's not working anywhere One step at a time :) You can only import a key after you've exported it.you have used a decommissioned app How did you get to this point?Title: Re: Recover BTC Post by: Cricktor on July 30, 2023, 03:47:17 PM If it is the following provider for the Lunu wallet (https://wallet.lunu.io/) then in one of the listed features the Lunu wallet doesn't appear to be custodial as it seems to provide mnemonic words for wallet backup and recovery. No first hand experience though herewith!
I would assume that Lunu didn't reinvent the wheel and used BIP-39 recovery words for their wallet. Do you have those recovery words of your Lunu wallet? If yes, there's some chances to restore the Lunu wallet in another more decent and better known software wallet like Electrum or Sparrow. Some more details would be nice, too. From which wallet or exchange did you send the coins to a receive address of your Lunu wallet? Can you describe in more detail how you got your receive address for your Lunu wallet? When you created the transaction to your Lunu wallet, did you thoroughly check that the transfer destination address is actually correct and unaltered? Did you check with some blockchain explorer like https://bitcoinexplorer.org or https://mempool.space that your transaction still exists? Maybe it's stuck in mempools due to too low transfer fee? I don't want to encourage you to disclose private details of your transaction, but if you feel overwhelmed or have no clue what we're talking about, you might consider to make your destination address and/or the transaction id of your transfer public. Think twice before you do that, it's fine if you don't want to. Such a disclosure can harm your financial privacy. Never make your recovery words public or enter them on an online site or handle private keys and recovery words on an online computer with questionable security status.

The transaction isn't Broadcasted? Unconfirmed? Which is the receiver? Lunu? The other "my wallet"? Which customer support are you talking to, who's they? I can't get the full picture of the issue because of the limited info. I also don't see the connection of importing your private key to possibly send/receive the transaction with the current info. Title: Re: Recover BTC Post by: BitMaxz on July 31, 2023, 09:43:32 AM If Cricktor is right the wallet you are using is the Lunu wallet app it seems the wallet is discontinued which is why the support tells you to export the private key.
Look at the image below I installed the Lunu app and there is a notice that this wallet is discontinued. https://i.ibb.co/cTbYyrV/20230731-172732.jpg After pressing the export button it would show you the WIF private key but you can also export it in another format look at the image below. https://i.ibb.co/Gsc70cf/20230731-172813.jpg So the problem with your issue is that the wallet is discontinued and maybe the wallet does not have access anymore to the server which is why you didn't receive anything in your wallet and that is why support suggests to export private and import it to other wallets. Title: Re: Recover BTC Post by: ibreathepoker on July 31, 2023, 04:11:45 PM Ok some extra info, yes i have a 24 word recovery seed
Transaction hash (blockchair.com): d492948c19e7f34eddf7382a37f958bff0fdcgaedc3e556effd8b6920ff98600 Sender wallet (bitcoin.com): 1B₩Y1LwfYTvccGmmN2zbGHAiJWXCVOEBex Reciever wallet (lunu): bc1qyeh7metapmvsvnxy8xtz4n9cu7tga7qsg2zpqw Both wallets are mine 0.02589711 amount btc $ 686.58 at the time i send it I tried to import my wallet according to what the lunu customer service told me, but the problem is the private key in "raw format", below the message customer service send me: Dear Customer, We have checked your issue and there are several solutions to this problem. The only one that does not require our participation (as we don't have access to your private data) is to find a wallet that allows you to import a private key in raw format, import the wallet key there and then transfer wherever you want. Here are some of them: Bitcoin Core (formerly known as Bitcoin-QT): The official Bitcoin wallet. You can import the private key in raw format using the importprivkey command in the wallet console. Electrum: This is a popular lightweight bitcoin wallet. You can import a private key in raw format by selecting the "Import private key" option from the "Find" menu or using the importprivkey command in the wallet console. Kind regards So i have to export my wallet in raw format but i can't find that raw format key anywhere only the 24 word recovery seed, and when i go to bitcoin core or electrum i can import my account bit its empty Hope someone has any idea on this issue, the 2 emails below tells me it is possible to get my btc restored: Dear Customer, Once you follow the instructions mentioned above you will be able to send the amount back to your wallet. Kindly note that we do not possess the amount you transferred. Kind Regards. Dear Customer, The problem is that you have used a decommissioned app, as you mentioned in the beginning of our conversation. We never got the amount you have transferred. We would like to advise you to export the raw key with your Lunu wallet konfigurations to get a possibility to forward your amount back to your personal wallet. Kind regards Title: Re: Recover BTC Post by: LoyceV on July 31, 2023, 04:25:07 PM I tried to import my wallet according to what the lunu customer service told me You should do what BitMaxz showed first. You can only import a key after exporting it.Title: Re: Recover BTC Post by: Cricktor on July 31, 2023, 10:34:39 PM Did you transfer and type "d492948c19e7f34eddf7382a37f958bff0fdcgaedc3e556effd8b6920ff98600" manually by hand? The 'g' is rather a '9' instead.
For recovery or experiments with "naked" private keys you need a secure and expendable/wipeable environment. If you're not experienced with that, I don't want to be responsible that your keys might leak into wrong hands. You can boot TAILS from a thumbdrive or similar (TAILS has Electrum in an older version installed and you can use that version for a wallet recovery with ease). Be careful to cut internet connectivity when appropriate (easy with TAILS). Your recovery words should not be used/entered on a digital device that is online. Don't "massage" your private keys while online. Period! I assume Lunu wallet used BIP-39 compatible recovery words and nothing in addition fancy that's not documented. Let's hope for the best. Your receive address in Lunu was a native segwit address, thus I assume a standard native segwit derivation path of m/84'/0'/0'
If Lunu was all standard, your wallet should now be restored in Electrum. There are some edge cases possible for this to fail, but I'm not going to discuss them unless an empty wallet emerges. If above doesn't work and you need to import raw (hex?) private keys, they would need to be in compressed WIF format for a native segwit wallet. You can convert raw hex private keys into WIF format e.g. with offline version of bitaddress.org downloaded and verified from the Github page https://github.com/pointbiz/bitaddress.org (https://github.com/pointbiz/bitaddress.org). (Beware of malicious copycat sites and typo-domains of https://bitaddress.org (https://bitaddress.org), the "original" is safe to my knowledge and audit.) Go offline before you handle private keys! On page "Wallet Details" you can enter hex raw private keys and have compressed WIF representation displayed below on the right side (left is the uncompressed WIF private key representation). E.g. the private key in hex 0000000000000000000000000000000000000000000000000000000000000001 converts to WIF KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU73sVHnoWn (compressed) -- the native segwit public address of this key has 26 transactions in the past; the uncompressed key's p2pkh address more than 1400! Some people are crazy, indeed. You can import that private key in Electrum as p2wpkh:KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU73sVHnoWn (quick steps: create new wallet, import private keys, enter with p2wpkh: prefix for native segwit addresses) If you're unsure or don't understand a step, better ask than do something less smart. Title: Re: Recover BTC Post by: nc50lc on August 01, 2023, 05:10:06 AM Ok some extra info, yes i have a 24 word recovery seed Unfortunately, it seems like Lunu's 24-word BIP39 recovery phrase although valid, uses its own unique derivation path and there's no documentation about it.I tried to restore my test wallet using common paths and none generated the correct receiving address. Reciever wallet (lunu): But luckily, the Wallet Import Format (WIF) private key is the pair of the receiving address.bc1qyeh7metapmvsvnxy8xtz4n9cu7tga7qsg2zpqw You can export that using BitMaxz's instructions and import it securely using Cricktor's suggestion to use Tails but using the WIF private key. If you can "risk" the amount and think that your system is safe (like what you usually do), you can just import it to Electrum via "Import Bitcoin Address or private keys" in new wallet menu. Then paste the WIF private key with the prefix p2wpkh: ; example: p2wpkh:L3BxN68HQp7zUv89ifFNDebU...... The choice is yours. Title: Re: Recover BTC Post by: ibreathepoker on August 01, 2023, 03:05:58 PM Thanks everybody for the help this option worked out

I tried to restore my test wallet using common paths and none generated the correct receiving address. The Lunu wallet didn't look convincing to me but that is purely stupid from them and a big red flag. They deserved to become decomissioned. It's already dumb to use some non-standard derivation path but not to document some crazy unique derivation is ... (I have no polite words for this). Thanks everybody for the help this option worked out Excellent, good to read. Do you mind to describe a little more in details what finally helped you? I assume you were able to export your private key in WIF format and not in raw HEX format which would require an additional conversion step to import the key into Electrum. The Electrum private key import dialog actually explains the required key prefixes for specific address types: Code: WIF keys are typed in Electrum, based on script type. And p2pkh:5HpHagT65TZ... is possible for uncompressed private keys in WIF format giving you uncompressed legacy public address. Title: Re: Recover BTC Post by: ibreathepoker on August 01, 2023, 09:28:16 PM I literally typed
p2wpkh : followed by my lunu wif and put it in electrum and it worked and my balance was there Title: Re: Recover BTC Post by: dkbit98 on August 01, 2023, 09:34:30 PM If you can "risk" the amount and think that your system is safe (like what you usually do), you can just import it to Electrum via "Import Bitcoin Address or private keys" in new wallet menu. I am glad you managed to recover access to your coins and learned something along the way.Then paste the WIF private key with the prefix p2wpkh: ; example: p2wpkh:L3BxN68HQp7zUv89ifFNDebU...... The choice is yours. In future it is better to stay away from using obscure wallets like Lunu, and don't hold coins on centralized exchanges, or you won't be so lucky next time ;) Try to stick to proven and tested open source wallets/devices and decentralized exchanges like Bisq. PS I think some people can earn a nice amount of money helping other people recover ''lost'' coins, but at least they deserve donations 8) |
