This is a simple generator of BIP49 wallets in testnet
Requires node v11
npm install
npx ts-node src/index.ts --nb_addresses 1 --transactions 1
The output gives a transaction to fund the wallet. You can broadcast it from here: https://live.blockcypher.com/btc-testnet/pushtx/
To allow the creation of the wallet with transactions, the script uses a pre-founded BIP49 wallet (only index 0 of HD wallet is used). It can be replaced by providing a new set of mnemonics with the option --faucet_mnemonics.
