        Highly experimental, pure python tool for cryptocurrencies.
        Please notice that coins could change their protocols so make sure the coin parameters are not outdated. 
        
        ## INSTALLATION
        
        ### Additional packages needed on Ubuntu
        ```bash
        sudo apt-get install build-essential python3-setuptools python3-wheel python3-dev python3-pip
        ```
        
        If you don't have Python 3, install it by following instructions from python.org. 
        Supported Python versions are 3.6, 3.7, 3.8, 3.9. Then run (using pip for python 3) :
        ```bash
        pip install multicrypto
        ```
        
        The package contains below commands:
         1. `sweepaddress` - combines many inputs into one
         2. `sendcrypto` - creates raw transaction and send it to insight explorer api
         3. `checkaddress` - checks address balance using insight explorer api
         4. `transaddress` - translates address to different coin format (resulting address will have the same private key) 
         5. `transprivkey` - translates WIF private key to different coin format
         6. `genaddress` - generates vanity address for given coin
         7. `signmessage`- signs message using ECDSA
         8. `verifymessage` - verify ECDSA signed message  
        
        ## USAGE
        Before running any commands it is advised to disable shell history. For example on linux it should 
        be enough to run:
        ```bash
        unset HISTFILE
        ```
        ### Run
        1. Combining many small inputs to larger ones.
        ```bash
        sweepaddress --coin_symbol=<COIN SYMBOL> --address=<ADDRESS> --private_key=<PRIVATE KEY> --minimum_input_threshold=<INT> --maximum_input_threshold=<INT>
        ```
        After mining some currency for longer period we could end up with address having a lot of small inputs. 
        In such case it is very likely it will be not possible to send the funds in one transaction and it could 
        be difficult to cope with. Let say for Zen Cash we have private key of the address which inputs 
        we want to combine, but we want only combine inputs which are smaller than 0.1 ZEN:
        ```bash
        sweepaddress -c ZEN -p KwDiDMtpksBAcfyHsVS5XzmirtyjKWSeaeM9U1QppugixMUeKMqp --maximum_input_threshold==10000000
        ```
        This will create appropriate number of transactions (by default one transaction for each 200 inputs, you can 
        override this value by setting parameter --batch_size, but setting it too high will result in too big transaction error),
        transaction fee will be set to default 0.00001 ZEN (you can override it using --fee parameter) and the
        funds will be sent back to original address (you can override the output address using --address parameter).
        2. Sending funds:
        ```bash
        sendcrypto --coin_symbol=<COIN_SYMBOL> --satoshis=<INT> --address=<ADDRESS> --private_key=<PRIVATE KEY> --minimum_input_threshold=<INT> --maximum_input_threshold=<INT>
        ```
        Sending (P2PKH) 0.25 BTC to address 1BTC1NNjeiAmFqe2n1QJjkEa4aMyAhkpKG with default fee 10000 satoshis
        and only using inputs containing not more than 100000 satoshis:
        ```bash
        sendcrypto -c BTC -s 25000000 -x 100000 -a 1BTC1NNjeiAmFqe2n1QJjkEa4aMyAhkpKG -p KwDiDMtpksBAcfyHsVS5XzmirtyjKWSeaeM9U1QppugixMUeKMqp
        ```
        Sending (P2PSH) 0.0019 BTC on testnet to address 2NDN55zZ6BtStckQWnhGJejBdM5EaGcNn7h with fee 5000 satoshis
        (notice that both input address 2NAMu8JCTLXtTv2LRQktByt1EoKaJaVmDAj and unlocking script 5106519351935387
        must be provided):
        ```bash
        sendcrypto -a 2NDN55zZ6BtStckQWnhGJejBdM5EaGcNn7h -c TBTC -i 2NAMu8JCTLXtTv2LRQktByt1EoKaJaVmDAj -u 5106519351935387 -s 190000 -f 5000
        ```
        3. Listing address inputs with total amount:
        ```bash
        checkaddress --coin_symbol=<COIN SYMBOL> --address=<ADDRESS> --minimum_input_threshold=<INT> --maximum_input_threshold=<INT>
        ``` 
        For example:
        ```bash
        checkaddress -c BTC -a 14YK4mzJGo5NKkNnmVJeuEAQftLt795Gec
        ```
        4. Translating address between coins:
        ```bash
        transaddress --address=<ADDRESS> --input_symbol=<COIN SYMBOL> --output_symbol=<COIN SYMBOL>
        ```
        For example to translate Bitcoin address 1BTC1NNjeiAmFqe2n1QJjkEa4aMyAhkpKG to Zcash address we enter:
        ```bash
        transaddress -a 1BTC1NNjeiAmFqe2n1QJjkEa4aMyAhkpKG -i BTC -o ZEC
        ```
        5. Translating private key in wif format between coins
        ```bash
        transprivkey --private_key=<PRIVATE_KEY> --output_symbol=<COIN SYMBOL>
        ```
        For example to translate Bitcoin private key KwDiDMtpksBAcfyHsVS5XzmirtyjKWSeaeM9U1QppugixMUeKMqp
        to Zcash private key we enter:
        ```bash
        transprivkey -p KwDiDMtpksBAcfyHsVS5XzmirtyjKWSeaeM9U1QppugixMUeKMqp -o ZEC
        ```
        6. Generating address with given pattern and corresponding private key:
        ```bash
        genaddress --pattern=<PATTERN> --symbol=<COIN SYMBOL> --output_dir=<DIRECTORY TO STORE QR CODES>
        ```
        For example if we want to create address with prefix t1aaaa for Zcash coin and save corresponding
        QR codes to /home/john directory we enter:
        ```bash
        genaddress -p t1aaaa -s ZEC -d /home/john
        ```
        To generate Bitcoin segwit address starting with 3BTC we enter:
        ```bash
        genaddress -p 3BTC -s BTC -w
        ```
        7. Signing message proving ownership of an address:
        ```bash
        signmessage --coin_symbol=<COIN SYMBOL> --private_key=<PRIVATE KEY> --message=<MESSAGE TO SIGN>
        ```
        For example proving ownership of BTC address 1HCfFoucNXgYLvpcN2X4TwmUXJjGUMJ2hi:
        ```bash
        signmessage -c BTC -p KzReaUKzSaGarrhFhjNMweTrpUx4gqX1KCMFSWJx9374kYNHpmSu -m "Hello World!"
        ```
        will return: `H7Ul0s8Za640duU2MhsifCX1H3Ma2NKRtLvtLYye6mFpZTW0fgXbM//bXq1yeXLHphXi8BUjtBsBHy0zrZjCYsQ=`
        
        8. Verifying if signed message was created using private key of given address:
        ```bash
        verifymessage --coin_symbol=<COIN SYMBOL> --address=<ADDRESS> --message=<MESSAGE> --signed_message=<SIGNED MESSAGE>
        ```
        For example verifying if `H7Ul0s8Za640duU2MhsifCX1H3Ma2NKRtLvtLYye6mFpZTW0fgXbM//bXq1yeXLHphXi8BUjtBsBHy0zrZjCYsQ=`
        is signed `Hello World!` message by owner of BTC address 1HCfFoucNXgYLvpcN2X4TwmUXJjGUMJ2hi we run:
        ```bash
        verifymessage -c BTC -a 1HCfFoucNXgYLvpcN2X4TwmUXJjGUMJ2hi -m "Hello World!" -s H7Ul0s8Za640duU2MhsifCX1H3Ma2NKRtLvtLYye6mFpZTW0fgXbM//bXq1yeXLHphXi8BUjtBsBHy0zrZjCYsQ=
        ```

        ## Tests
        Install pytest, pytest-cov and tox packages:
        ```bash
        pip install -r requirements_dev.txt
        ```
        Run tests and check report htmlcov/index.html:
        ```bash
        python -m pytest --cov=./ --cov-report=html
        ```
        To run tests on various python versions run:
        ```bash
        tox
        ```
        
        ## Adding new coin
        1. Add new entry in `settings.py`. Prefix bytes are usually defined in chainparams.cpp or 
        base58.h files. 
        
        Exemplary for Zen we have:
        ```bash
        'ZEN': {
            'name': 'zen cash',
            'address_prefix_bytes': b'\x20\x89',
            'secret_prefix_bytes': b'\x80',
            'script_prefix_bytes': b'\x1c\xbd',
            'params': {'check_block_at_height': True},
            'apis': [
                {'url': 'https://explorer.zensystem.io/insight-api-zen'}
            ]
        }
        ```
        2. Update this readme with new supported coin and add appropriate tests
