Calculation of BTC, ETH and BNB wallets using a private key with a balance check

Features & Capabilities

Key Hunter - Bitcoin Checker is a powerful Chrome extension designed to calculate Bitcoin, Ethereum, and Binance Smart Chain (BNB) wallet addresses from private keys while checking their balances. If a positive balance is found, the private key, wallet address, and balance are securely stored in an internal database.

The extension features graphical visualization of private keys, automatic randomization of private keys, and background searching for wallets with balances. It supports private key conversion to WIF compressed and uncompressed formats. Additionally, users can search for compressed Bitcoin addresses by specifying search parameters and compare against known public keys, including a unique feature that checks for matches against over 34,000 "Satoshi" public keys holding 50 bitcoins each. Notifications alert users upon successful matches. This tool operates fully offline, enhancing user privacy and security.

Would be great if it could look at addresses with lower balances. I'd be more than happy with finding only 3 or 4 BTC... Glad we can also try to solve the puzzle at the same time!
