TRON API for Python

A Python API for interacting with the Tron (TRX)

A Command-Line Interface framework

You can install it in a system-wide location via pip:

sudo pip3 install tronapi

Or install it locally using virtualenv:

virtualenv -p /usr/bin/python3 ~/tronapi
source ~/tronapi/bin/activate
pip3 install tronapi

Usage

Specify the API endpoints:

Smart Contract

from tronapi import Tron
from solc import compile_source

full_node = 'https://api.trongrid.io'
solidity_node = 'https://api.trongrid.io'
event_server = 'https://api.trongrid.io'

tron = Tron(full_node=full_node,
        solidity_node=solidity_node,
        event_server=event_server)

# or default (tron = Tron())


# Solidity source code
contract_source_code = '''
pragma solidity ^0.4.25;

contract Hello {
    string public message;

    function Hello(string initialMessage) public {
        message = initialMessage;
    }

    function setMessage(string newMessage) public {
        message = newMessage;
    }
}

'''

compiled_sol = compile_source(contract_source_code)
contract_interface = compiled_sol['<stdin>:Hello']

hello = tron.trx.contract(
    abi=contract_interface['abi'],
    bytecode=contract_interface['bin']
)

# Submit the transaction that deploys the contract
tx = hello.deploy(
    fee_limit=10**9,
    call_value=0,
    consume_user_resource_percent=1
)

Base Example

from tronapi import Tron
logging.basicConfig(level=logging.DEBUG, format="%(asctime)s - %(levelname)s - %(message)s")
logger = logging.getLogger()

full_node = 'https://api.trongrid.io'
solidity_node = 'https://api.trongrid.io'
event_server = 'https://api.trongrid.io'

tron = Tron(full_node=full_node,
        solidity_node=solidity_node,
        event_server=event_server)

account = tron.create_account
is_valid = bool(tron.trx.is_address(account.address.hex))

logger.debug('Generated account: ')
logger.debug('- Private Key: ' + account.private_key)
logger.debug('- Public Key: ' + account.public_key)
logger.debug('- Address: ')
logger.debug('-- Base58: ' + account.address.base58)
logger.debug('-- Hex: ' + account.address.hex)
logger.debug('-- isValid: ' + str(is_valid))
logger.debug('-----------')

transaction = tron.trx.get_transaction('757a14cef293c69b1cf9b9d3d19c2e40a330c640b05c6ffa4d54609a9628758c')

logger.debug('Transaction: ')
logger.debug('- Hash: ' + transaction['txID'])
logger.debug('- Transaction: ' + json.dumps(transaction, indent=2))
logger.debug('-----------')

# Events
event_result = tron.trx.get_event_result('TGEJj8eus46QMHPgWQe1FJ2ymBXRm96fn1', 0, 'Notify')

logger.debug('Event result:')
logger.debug('Contract Address: TGEJj8eus46QMHPgWQe1FJ2ymBXRm96fn1')
logger.debug('Event Name: Notify')
logger.debug('Block Number: 32162')
logger.debug('- Events: ' + json.dumps(event_result, indent=2))

Missing voting and freezing features?

Maybe I missed it, but I did not see anything about freezing or voting in the examples or in the docs. Is this expected to be added soon?

How to call a constant function without spending energy?

example : string public message;

I tried to use "trigger_smart_contract" to call "message", but it cost energy.
what is the correct way to call it?

Receiving revert response from contract trigger

I am running below code to trigger TronBet contract

parameters=[{'type': 'uint256', 'value': rollvalue}, {'type': 'uint256', 'value': direction}]#, {'type': 'uint64', 'value': "roll"}] parameters=[{"value":rollvalue,"type":"uint256"},{"value":direction,"type":"uint256"}] tx=tron.transaction_builder.trigger_smart_contract('TEEXEWrkMFKapSMJ6mErg39ELFKDqEs6w3','GoodLuck',fee_limit,bet_value,parameters)#,'TQR27jXR4dHdDtjE63MnnUQvecK97rop2y') #print(tx) #tx=tx['transaction'] tx=tron.trx.sign(tx)#,True) tron.trx.broadcast(tx)

Everything goes fine but contract is not triggered. When I enquire trx then I get below info

{'ret': [{'contractRet': 'REVERT'}], 'signature': ['0219801893a402337d882c09e598780579d9c21a6ab1d7cdd21ca452e50fbd884830f2892998bdfab2360240b3007aaf6cd29ad76b2005886d547d307f36a8bf1b'], 'txID': '32308a59ebd4b6442fb49f1914e6e5c7636fb0144eefd79f0e75f981f9ab159d', 'raw_data': {'contract': [{'parameter': {'value': {'data': '16bd160c00000000000000000000000000000000000000000000000000000000000000320000000000000000000000000000000000000000000000000000000000000000', 'owner_address': '419e737d5db19beafc2a9a813211cc73add2d3a872', 'contract_address': '412ec5f63da00583085d4c2c5e8ec3c8d17bde5e28', 'call_value': 10000000}, 'type_url': 'type.googleapis.com/protocol.TriggerSmartContract'}, 'type': 'TriggerSmartContract'}], 'ref_block_bytes': 'cf50', 'ref_block_hash': 'c25f1caca6eb80d0', 'expiration': 1546335174000, 'fee_limit': 600000, 'timestamp': 1546335116934}}

So it is reverted. Code failed to trigger the contract.

Please check. What is wrong and how to fix it

Взаимодействие со смарт контрактом

Good afternoon, tell me how to correctly call the smart contract function, which requires sending money, thank you.

Mac, pip install tronapi, ImportError: No module named eth_account

After installed tronapi by sudo pip install tronapi, and run python account.py in examples documents, showing error:

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    from tronapi import Tron
  File "/Volumes/D/coins/tron/tron-robot/tronapi/__init__.py", line 11, in <module>
    from eth_account import Account  # noqa: E402
ImportError: No module named eth_account

I checked installation logs, shows
Requirement already satisfied: eth-account<0.4.0,>=0.2.1 in /usr/local/lib/python3.7/site-packages (from tronapi) (0.3.0)
What should I do ?
Thank you

'NotFoundError' on get_transactions_to_address

Hi,

i'm currently executing this:

account = Tron().create_account

tron = Tron(**{"private_key": account.private_key, "default_address": account.address.hex})

address = tron.default_address.hex
transactions = tron.trx.get_transactions_to_address(address=address)

But i get this error on the last line:

tronapi.exceptions.NotFoundError: (404, '{"error":{"code":404,"status":"Not Found"}}', {'error': {'code': 404, 'status': 'Not Found'}}, 'https://api.trongrid.io/walletextension/gettransactionstothis')

But if i execute https://developers.tron.network/reference#transaction-information-by-account-address directly then it works.

Support setting permission_id in trx.sign for multisig

When trying to do multi-signature using an 'active' permission you need to be able to set the Permission_id in the transaction's contract e.g.

create_tx["raw_data"]["contract"][0]["Permission_id"] = 2

However, the problem here is that the transaction's raw data, and therefore the txID will need to be changed as a result of updating the transaction.

TronWeb handles this situation by taking a permissionId argument to its trx.multisign function, which if >0 where the transaction's contract doesn't have a Permission_id already, causes TronWeb to add the Permission_id to the contract before POSTing the transaction to wallet/getsignweight which then returns an updated transaction (in transaction.transaction) containing a corrected txID, which can then be signed.

This is how the code might look using tronapi to do the signing after this issue is fixed (in this case the wallet/getsignweight is only done on the first call to trx.sign):

create_tx = tron.transaction_builder.send_transaction('to', 1, 'from')
tron.private_key = 'first private_key'
signed1_tx = tron.trx.sign(create_tx, multisig=true, permission_id=2)
tron.private_key = 'second private_key'
signed2_tx = tron.trx.sign(signed1_tx, multisig=true, permission_id=2)
response = tron.trx.broadcast(signed2_tx)

Something like this should be added to your examples scripts to show how multisign should be used.

How to check TRC20 token balance?

How do i check the balance of a TRC20 token for a given TRX address?

how transaction serialization and deserialization?

here I encounter another question. As ethereum uses RLP for serializing data. Does tron uses GoogleProtocol to serialize data ?

How the process is in tron-pathonapi?
where can i find solution ? or can you tell me some idea about how to serialization and deserialization locally?
I am really suffering from it ,looking forward to your reply.

Thanks a lot!

Can you change comments to english?

    }
}

so, may be line 575 improve better?
owner_address = transaction['transaction']['raw_data']['contract'][0]['parameter']['value']['owner_address']

Missing functionality for interacting with contracts?

There seems to be code to deploy a contract but nothing to interact with it. You can get by by passing the "parameter" argument in as a keyword argument when creating a contract,, although there's some massaging that needs to be done to get it in the right format, which I haven't gotten around to implementing yet (or does it already exist somewhere?).

Likewise, there's no function that calls /wallet/triggersmartcontract although, one can work around it like so:

    return tron.manager.request('/wallet/triggersmartcontract', {
        'contract_address': contract_address,
        'owner_address': host.address.hex,
        'function_selector': function_name,
        'fee_limit': 1000000,
        'call_value': 0,
        'parameter': params
    })

There's appears to exist a ContractFunction class that comes back if you do contract.all_functions(), but it's not clear to me how its intended to be used. I can see in tron web that the parameters are encoded using parameters = abiCoder.encode(types, values).replace(/^(0x)/, '') but I'm not seeing any similar functionality here.

what's transaction detail?

i find method of offline_sign(),but i don't know the detail of parameter(transaction),can you help me?
I don't find detail in trx document.In addition,do you know how to mul-sign in trx?It looks like you should be good at eth and ripple,i can mul-sign in eth and ripple.Do they have anything in common?trx can use solidity too.

TRC10 SELL transaction for poloniex

Hi I'm use this lib for work with polonium api and make transactions to exchange
every transactions is working except sell trc10 tokens

I.m use this code for make transaction

            order_symbol_Poloniex = 1002000

            buy_Trc10 = self.tron.transaction_builder.trigger_smart_contract(
                contract_address=trc10Contract,

                fee_limit=10000000,
                token_id=1002000,
                token_value=0,
                parameters=[
                    {'type': 'int256', 'value': order_symbol_Poloniex},

            buy_Trc10_signb.sign_and_broadcast(buy_Trc10_sign)
            return buy_Trc10 ```

but if token_id or token_value there then 0  I got exception

where is mistake?

Receiving KeyError: 'raw_data'

I wished to send a bet transaction to tronbot. I used below code for that
fee_limit =1000000000 multplier =1000000000 bet_value=10*multplier direction=0 rollvalue=50 parameters=[{"value":rollvalue,"type":"uint256"},{"value":direction,"type":"uint256"}] tx=tron.transaction_builder.trigger_smart_contract('TEEXEWrkMFKapSMJ6mErg39ELFKDqEs6w3','GoodLuck',fee_limit,bet_value,parameters,'TQR27jXR4dHdDtjE63MnnUQvecK97rop2y')

It produced below tx

but when used "tx=tron.trx.sign(tx,True)" command to sign it then it gives above error.

Please see what is the issue or suggest how can i solve it. Thanks a lot

full error is given below

owner_address = transaction['raw_data']['contract'][0]['parameter']['value']['owner_address']

:(

For a while working with this library and I can say that in addition to the existing bugs, it is not very convenient. Why is the Tron class, which is used to grant permissions to the tron account, named this way (Tron)? Why such a class has methods toBytes, to Int, to Hex and others, if it would be more logical to use them not on behalf of the object, but at least on behalf of the class (classmethod)?

API does not give Tether balance for any address

I am using below code to get token balance for an address:

`full_node = 'https://api.trongrid.io'
solidity_node = 'https://api.trongrid.io'
event_server = 'https://api.trongrid.io'

tron = Tron(full_node=full_node,
solidity_node=solidity_node,
event_server=event_server)

tron.private_key = 'my private key'
#tron.default_address = 'TQR27jXR4dHdDtjE63MnnUQvecK97rop2y'

account_info = tron.trx.get_account('TNaRAoLUyYEV2uF7GUrzSjRQTU8v5ZJ5VR')

print(account_info)
print(pd.DataFrame(account_info["asset"]))`

it does provide a dataframe of assets but tether balance is not there. And checked that this address has tether balance.

Pls help me out. thnx

Transaction expiration

Hi,

I'm using this repository for Tron transaction. I found that expiration time for each transaction is set to 60 seconds in Java source codes. How can I increase expiration time using tron-api-python?
If it's not possible in python, how can I solve it anyway?

output :

Python36 create account error

AttributeError: 'str' object has no attribute 'decode'

fix for python3:

passing an array as an argument to the contract method

tell me how to be, I can’t solve the problem, there is a method in the contract that takes arrays as parameters:

function_selector='pay_royaltie(address [], uint256[], uint256[])',

how do I generate transaction data correctly, i do so:

row_trans = tron.transaction_builder.trigger_smart_contract(
    contract_address=CONTRACT_TRX,
    function_selector='pay_royaltie(address [], uint256[], uint256[])',
    # fee_limit=30000,
    call_value=25000000000,
    parameters=[

        [{'type': 'int256', 'value': 2}],
        [{'type': 'int256', 'value': int(3)}],
    ]
)

and half tea the next mistake:

raise ValueError('Invalid parameter type provided: ' + abi['type'])
TypeError: list indices must be integers or slices, not str in transactionbuilder.py", line 563, in trigger_smart_contract

Examples do not show how to include owner details

I find that the documentation/examples do not mention how to create the tron instance with contract owner information. After reading the source code I was able to figure out the following code and it works. Without this, I kept getting errors during the contract deploy step.

test_url = 'https://api.shasta.trongrid.io'
tron = Tron(full_node=test_url, solidity_node=test_url, event_server=test_url,
            private_key='af2389b556*****',        # my private key
            default_address='TQB3j6w7****')     # my tron address

Any chance to update the document to include the following information?

TypeError: encoding without a string argument

tron-api-python/tronapi/main.py

Line 191 in ee9b69f

if self._private_key and _private_base58 != _base58:

Please update the most recent documentation

Anyone can help here?

    @staticmethod

        Args:

Is it opposite?
to_tron is abs(amount) / pow(10, 6)
from_tron is math.floor(amount * 1e6)

Add origin_energy_limit

This is currently supported using the existing code base due to the way keyword arguments are passed in:

with open("HelloWorldtron.json") as FILE:
    contract = json.load(FILE)

contract = ContractConstructor(
    tron,
    abi=contract['abi'],
    bytecode=to_bytes(text=contract['bytecode'])
)
tx = contract.transact(
    fee_limit=10**9,
    call_value=0,
    origin_energy_limit=9999
)

sign = tron.trx.sign(tx)
result = tron.trx.broadcast(sign)

However, if omitted (which it is in all examples), then the transaction will get rejected by a network running java-tron 3.2 or higher with an ambiguous CONTRACT_VALIDATE_ERROR. Validation should be added as well, such as:

        # Maximum energy consumption limit
        origin_energy_limit = kwargs.setdefault('origin_energy_limit ', 0)

        ...

        if not is_integer(origin_energy_limit) or origin_energy_limit < 0 or origin_energy_limit > 10 ** 9:
            raise ValueError('Invalid energy limit provided')

Bug in tronapi.trx.Trx.verify_message/sign.

Code example

TRON_SETTINGS = {
    'full_node': 'https://api.shasta.trongrid.io',
    'solidity_node': 'https://api.shasta.trongrid.io',
    'event_server': 'https://api.shasta.trongrid.io',
}

tron = tronapi.Tron(**TRON_SETTINGS)

account = tron.create_account  # XXX: create_account is property.
tron.private_key = account.private_key
tron.default_address = account.address.base58

message = tron.toHex(text='hello')
signed = tron.trx.sign(message)

tron.trx.verify_message(message, signed)

Result is always ValueError: Signature does not match.

I've inspected tronapi.trx.Trx.sign and tronapi.trx.Trx.verify_message and found that they have different code for header definition:

tronapi.trx.Trx.sign

            # Determine which header to attach to the message
            # before encrypting or decrypting
            header = TRX_MESSAGE_HEADER if use_tron else ETH_MESSAGE_HEADER
            header += str(len(transaction))

            message_hash = self.tron.keccak(text=header+transaction)

tronapi.trx.Trx.verify_message

        # Determine which header to attach to the message
        # before encrypting or decrypting
        header = TRX_MESSAGE_HEADER if use_tron else ETH_MESSAGE_HEADER

        message_hash = self.tron.keccak(text=header+message)

Adding header += str(len(message)) string into tronapi.trx.Trx.verify_message fixes the problem.

Get transactions to an address

I'm trying to extract what transactions have been sent to an address by using the tron.trx.get_transactions_related and tron.trx.get_transactions_to_address functions but when I do these, they error out.

tron.trx.get_transactions_to_address(addr)
