Tool to convert any number of private keys from Hexadecimal format to other formats as well as get their respective Bitcoin Addresses and Check all Balances automated.

I developed these tools for Bitcoin users, I hope they are useful and help save time.
https://github.com/geniusprodigy/mega-tool-pvkmassconvert -> convert pvk hex to WIF and WIFc, and generate separate lists of Addresses Compressed and Uncompressed.

https://github.com/geniusprodigy/bitcoin-balance-checker -> checks the balance of all lists' addresses automat- ically.

https://github.com/geniusprodigy/mnemonic-to-wif -> converts many mnemonic seeds to WIF at once, supports (seeds of 3, 6, 9, 12, 15, 18, 21, 24) words

Enjoy.

Does the new address format on Bitcoin Cash include modifications to the private keys?

I read some comments about wallets keeping compatibility with the old address format for a while, and I actually think it would be useful to keep it forever in case somebody finds a paper wallet 20 years from now. But then I realized maybe my concern is not founded because maybe the private key will not be changed.
Can somebody clarify this?
Thanks in advance.

Does Dash use the same private key format as Bitcoin?

Does this mean that hypothetically someone can use a single paper wallet to generate the public address for Dash and Bitcoin?

BlockCypher signing Bitcoin transaction incorrect private key format

I am trying to sign a Bitcoin transaction using the BlockCypher API but I am failing because I don't have my private key in the correct format.
According to their documentation:
"One of the most common errors in the signing process is a data format mismatch. We always return and expect hex-encoded data, but oftentimes, standard signing libraries require byte arrays. Remember to convert your data, and always send hex-encoded signatures to BlockCypher."
The PHP code should be as follows:
$privateKeys = array("2c2cc015519b79782bd9c5af66f568e808f573714f3c4dc6df7d79c183783cff"); $txSkeleton = $txClient->sign($txSkeleton, $privateKeys);
But my private key is in the format:
xprv9s21ZrQH143K4NejhhRcspQdS2g7JgnSVwmT2dkXQuszJaQqjYD3wdUdsXyqmfetdUZ2SS25uM7nAfnUwNDGA75bfqYxKwYZ8zDdaCv6meL
i.e. not in hex.
I have tried simply converting it to hex, which obviously was a bit overoptimistic of me but the transaction signing fails.
I have Googled and Googled this for weeks and have been unable to figure out how to convert a xprv prefix key into the correct format as required by the BlockCypher API.
I am a paying customer of theirs and have e-mailed them but no reply after two weeks of waiting.
I'm at my wits end and any help would be very much appreciated.

Newbie Question:

So i have this public and private keys generated from a mobile wallet. Is it possible to access my funds using these keys outside the software wallet? Can I also use these keys to access my funds on a different wallet? One last thing, are the recovery phrase only for recovering your account on a specific wallet and can't be recoverable on another wallet service?

How to create a BIP49/BIP84 pair of private/public keys from a 256 bits number

Hi there,
I am trying to understand how private and public keys are constructed.
I have managed to create a base58 private key from a 256 bits number (the private key key starts with a 5).
However, when I upload this private key into electrum, I can see that the corresponding receiving addresses start with 1.
How to buid a private key from a 256 bits number that will generate addresses starting with 3 (BIP49) or bc1 (BIP84) ?
Thank you.

Too many people over at r/bitcoin would rather have new users lose funds than help them recover them, as long as it reinforces the "BCH is a scam" narrative.

https://np.reddit.com/Bitcoin/comments/ggwdy7/i_accidentally_sent_bch_to_my_btc_wallet_please/
Long story short: OP is a newcomer who bought BCH at bitcoin.com thinking they were buying BTC, and mistakenly sent it to a BTC address.
They asked for help on reddit, and they overwhelmingly got responses of the type "Sorry for your loss" and "You have been scammed", leading them to believe they lost their funds.
OP actually responded to a post which told them they lost their money, actually believing that was the case. Conceivably, based on these responses OP could have deleted the wallet, ACTUALLY losing the funds.
Some subreddit mods came as well, and impressively, they did NOT inform OP that the funds were recoverable, they directed OP to ask conman Roger for their money.
As is turns out, the address was not segwit, thus the funds were fully recoverable.
Thankfully, some redditors guided OP to recover the funds but makes me wonder how many other newcomers might not have OP's luck and actually lose their funds because of people over there misguiding them, since they either are ignorant, or pushing a narrative is more important to them than actually helping newcomers recover their money.
Edit: Aaand, here it is: I have just been banned from bitcoin for letting OP know how to recover their funds!
Given reason:
Note from the moderators:
brigading altcoin scammer
Also the moderator removed another reply comment that was thanking me for actually being helpful in guiding OP recover their funds.
