This repository contains a simple extendable PHP console utility.

The purpose of this utility is provide to you full control on your own Bitcoins without external wallets.

You can generate new Bitcoin address with keys stored in strangely named archive (wallet), encrypted with password. Then you can see some basic info on your address and transactions corresponding with this address, or transfer some BTC to another address, providing amount and fee yourself (don't forget to remember the password to your wallet - there is no way to restore it).

Requires PHP version 7.x because of https://github.com/Bit-Wasp/bitcoin package requirements.

Depends on https://blockchain.info web resource functionality via https://github.com/blockchain/api-v1-client-php package.
