There have been a number of pretty scammy "split-your-coins" things popping up, but this one is at least something you can run locally produced by @hampus and @nitesh (the guys behind Noah Wallet).
Here's what hampus has to say about usage:
BcashJr Wallet is a self-custodial wallet for Windows, macOS and Linux that lets you split your Bitcoin and Blake-chain coins using Blake-chain’s replay protection, SIGHASH_UNIFIED.
You can send the Blake coins to yourself or directly to an exchange that supports them. The Blake-side transaction is invalid on Bitcoin, so your BTC coins stay in place.
Once the split confirms, you can send your Bitcoin back to your normal wallet.
The wallet code has been security reviewed by ChatGPT 5.6 Sol and Kimi 3.
Usage guide:Notes and recommendations:
- Create a fresh wallet, write down the recovery phrase offline, and send a small amount of BTC to its receive address.
- Sync and check that the deposit also appears on Blake-chain. It may be replayed automatically. If it isn’t, the built-in replay panel can attempt to replay the funding transaction. This only works if the transaction is valid on Blake-chain.
- Once the deposit has the required confirmations, select the shared coins in the BLAKE panel and send them to yourself or to an exchange’s Blake-chain deposit address. This is the split.
- Wait until the wallet shows the split as confirmed, then send your BTC from the Bitcoin panel back to your normal wallet.
Have fun stacking more BTC!
- Send in small amounts! This is a desktop hot wallet and therefore carries risk. Send small amounts, split the coins, and then send back the BTC to your normal wallet, then repeat.
- Use a fresh recovery phrase. Importing the seed from your normal Bitcoin wallet is not recommended.
- Remember your password. This is used to encrypt the wallet on disk.
- Use coin control when funding the wallet. Check that every selected input also exists and is unspent on Blake-chain.
- Check Blake-chain transactions on mempool.guide.
- Syncing is manual. Don't spam the sync button as you can get rate-limited by mempool.space (Bitcoin backend) and mempool.guide (Blake backend).
- Sell your Blake-coins on Neoxa Exchange, which has BTC, USDC, and USDT pairings.
- Every selected UTXO is spent in full. Everything goes to one destination, minus fees, with no change output.
Special thanks to @nitesh_btc and softsimon for helping test the wallet.
There still seems to only be one exchange that has listed bcash-jr, and I can't quite tell if it's shady or not, but as of today at utc 1800, it seems that bcash-jr coins are trading for anywhere between $500 and $1700 per coin. Also note that the exchange says its own 24H volume is 0.21 bcash-jr, so it's not exactly a high volume market.
$500 and $1700 per coin is surprising but at 0.21/24H that doesn't mean much other than someone bought a couple hundred dollars worth.
yesterday it was hovering between $170 and $280, there was a big jump earlier today. But I am still quite skeptical that there isn't wash trading going on or something. Neoxa is not exactly a huge exchange. I'm wondering if someone didn't acquire them or make a deal with them to set up a trading for bcash-jr.
There is also a fork of Sparrow wallet for bcash-jr, called Shrike:
Very confusing situation with Neoxa, after the social media posts about an end-user suffering a loss (a ticket may not have been filed) I thought there was social media from the exchange about not wanting all the bad feedback they were getting.
Maybe that was BS, as this blake2b coin is still trading there.
Any further representational research? This does seem to have been around a little awhile prior to the hard fork.
Anyone know deposit minimums, withdrawl minimums? Relevant for a risk mitigation strategy of moving in small amounts of blake2b, trading, withdrawing something useful (doesn't have to be bitcoin if fee efficient to do something else)
I wouldn't deposit bitcoin-sha256 there but there may be some logic to taking a flyer with the blake2b coins.
I think it was an isolated issue, and their support has responded.
I have successfully deposited and withdrawn many times on Neoxa.
Thank you for the post!
If anyone is having issues, please let me know.
Please send in small chunks of BTC to be safe. Move each BTC chunk away from the wallet after the split has completed. Don't dump your whole stash to the wallet at once.
You're luck DCs not here 🤣🤣🤣 he'll be turning in his lair
Self-custodial wallets that expose a clean lud16 (and ideally allowsNostr) are the quiet unlock for value-for-value social. Receipts are nice; landed sats are nicer.
