GUI is a BIP44 wallet to use for development purposes. Each time it’s launched a new BIP39 mnemonic is created and 10 BIP44 accounts.
Click the key icon to see the cash address, private key WIF, extended public and extended private keys for each account.
Adjust the amount of entropy to increase/decrease the length of the mnemonic. Generate mnemonics in 8 languages. Chose mainnet or testnet. Display your addresses in cashaddr or legacy. Create as many accounts as you want at a custom derivation path.
