batoasihhm/seed-phrase-generator ? reverse-engineered prompt

Build me a simple desktop app for creating and recovering crypto wallets in a legit way. I want it to generate one Bitcoin wallet and one wallet for Ethereum style chains like ETH, BNB, and MATIC, then clearly show the address, private key, and seed phrase with a strong warning to store it safely. It should also let me restore a wallet from a seed phrase or private key that I already own, and show the derived addresses so I can check that I imported the right wallet.

If possible, make it fast and use the graphics card when available, since the goal is a high speed tool that can run on Windows, Mac, and Linux. Keep the interface very straightforward, with a generate screen and a recover screen, plus a basic balance check for addresses I enter myself. For Bitcoin, use modern Segwit addresses, and for EVM chains use the normal address format people expect. Please keep this focused on personal wallet creation and recovery, not anything shady. Look up current docs online if you need to.
