A BTC & Blake-chain wallet to split your coins using Blake-chain's replay protection. - smolcars/bcashjr-wallet

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: 1. Create a fresh wallet, write down the recovery phrase offline, and send a small amount of BTC to its receive address. 2. 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. 3. 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. 4. Wait until the wallet shows the split as confirmed, then send your BTC from the Bitcoin panel back to your normal wallet. Notes and recommendations: - 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

- 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 https://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. Have fun stacking more BTC! Special thanks to @nitesh and @npub1hvw0...5e8q for helping test the wallet.
