# newrl
This library contains wrapper functions for interacting with the Newrl blockchain. Off chain and on chain operations are available.

## Installation
Add `newrl` to your project requirements 
and/or run the installation with:
```shell
pip install newrl
```


## Usage

### Initialise a node connection
A node address along with port can be given to initialise a new node connection. If no address is provided, the default newrl foundation node at address `http://newrl.net:8090` will be used.

```python
    node = Node('http://3.6.236.206:8090/')
```

### Off chain operations
#### Get file hash
Certain Newrl operations use document hashes for verification purpose. A file hash can be obtained with the below command.

```python
from newrl import get_file_hash
    file_hash = get_file_hash('/Users/admin/Documents/Tokenisation_Agreement1.pdf')
    print(file_hash)
```

#### Generate new wallet
A wallet address generation can be done off-chain. The result is a dictionary containing public, private and address of the new wallet. A wallet once generated should be added to the chain to make it available for use.

```python
    from newrl import generate_wallet_address
    
    wallet = generate_wallet_address()
```

#### Sign transaction
A transaction need to be signed with the applicable wallet for addition to chain.
```
    from newrl import sign_transaction

    signed_wallet_add_transaction = sign_transaction(wallet, wallet_add_transaction)
    print(signed_wallet_add_transaction)
```

### On chain operations
#### Add wallet to chain
A wallet address once genearated need to be signed and then added to the chain.
```
    def add_wallet(
        custodian_address: str,
        jurisdiction: str,
        public_key: str,
        ownertype: str = '1',
        kyc_docs: list = [],
        specific_data: dict = {},
    )
```
Example
```
    wallet_add_transaction = node.add_wallet(
        wallet['address'], '910', wallet['public'], 1)

    print(wallet_add_transaction)
```

#### Add token to chain
A token can be created, signed and then validated to add to the chain.
```
def add_token(
        token_name: str,
        token_type: str,
        first_owner: str,
        custodian: str,
        legal_doc_hash: str,
        amount_created: int,
        value_created: int,
        disallowed_regions: list = [],
        token_attributes: dict = {},
        is_smart_contract_token: bool = False,
    )
```
Example
```
    token_add_transaction = node.add_token(
        'my_new_token',
        '1',
        '0x16031ef543619a8569f0d7c3e73feb66114bf6a0',
        '0x16031ef543619a8569f0d7c3e73feb66114bf6a0',
        'fhdkfhldkhf',
        10000,
        10000,
    )
```

#### Add transfer
A transfer can be created between two wallets either unilaterally or bilaterally depending on the transfer type.
```
def add_transfer(
        self,
        asset1_code: int,
        asset2_code: int,
        wallet1_address: str,
        wallet2_address: str,
        asset1_qty: int,
        asset2_qty: int,
        transfer_type: int = 4,
    )
```
Example
```
    transfer_transaction = node.add_transfer(
        9, 10, '0x16031ef543619a8569f0d7c3e73feb66114bf6a0', '0x16031ef543619a8569f0d7c3e73feb66114bf6a0', 10, 10, 4)
    signed_transfer = sign_transaction(wallet, transfer_transaction)
    print(signed_transfer)
```

#### Get balance
The balance of a given token in a wallet, across wallets or all tokens in a wallet can be obtained with get balance function.
```
    node.get_balance(balance_type, wallet_address, token_code)
```
Example
```   
    node.get_balance('TOKEN_IN_WALLET', '0xc29193dbab0fe018d878e258c93064f01210ec1a', 9)
```

#### Validate transaction
A singed transaction need to be validated to be added to the chain.
```
    validate_result = node.validate_transaction(signed_transfer)
    print(validate_result)
```

#### Run updater
Run the miner to create a new block out of the transactions. If no valid transactions are found then an empty block will be created. This operation is not meant to be called and supposed to be run automatically by a chosen node at different intervals of time.
```
    response = node.run_updater()
    print(response)
```
