Overview

EthTx - Ethereum transactions decoder

Python Black OpenSource Apache

Installation

pip install ethtx

Requirements

The package needs a few external resources, defined in EthTxConfig object:

  1. Geth node - required to have access to the raw Ethereum data; it must be a full archive node with the debug option ON
  2. MongoDB database - required to store smart contracts' ABI and semantics used in the decoding process; it can be a Mongo Atlas or local instance
  3. Etherscan API key - required to get the source code and ABI for smart contracts used in transaction

Getting started

from ethtx import EthTx, EthTxConfig
from ethtx.models.decoded_model import DecodedTransaction


ethtx_config = EthTxConfig(
    mongo_connection_string= ##MongoDB connection string,
    mongo_database= ##MongoDB database,
    etherscan_api_key= ##Etherscan API key,
    web3nodes={
        "mainnet": ##Geth archive node URL,
    },
    default_chain="mainnet",
    etherscan_urls={
        "mainnet": "https://api.etherscan.io/api",
    },
)

ethtx = EthTx.initialize(ethtx_config)
transaction: DecodedTransaction = ethtx.decoders.decode_transaction('0x50051e0a6f216ab9484c2080001c7e12d5138250acee1f4b7c725b8fb6bb922d')

Features

EthTx most important functions:

  1. raw node data access:
ethtx = EthTx.initialize(ethtx_config)
web3provider = ethtx.providers.web3provider

from ethtx.models.w3_model import W3Transaction, W3Block, W3Receipt, W3CallTree

# read raw transaction data directly from the node
w3transaction: W3Transaction = web3provider.get_transaction('0x50051e0a6f216ab9484c2080001c7e12d5138250acee1f4b7c725b8fb6bb922d')
w3block: W3Block = web3provider.get_block(w3transaction.blockNumber)
w3receipt: W3Receipt = web3provider.get_receipt(w3transaction.hash.hex())
w3calls: W3CallTree = web3provider.get_calls(w3transaction.hash.hex()
  1. ABI decoding:
from ethtx.models.objects_model import Transaction, Event, Call
from ethtx.models.decoded_model import DecodedEvent, DecodedCall, DecodedTransfer, DecodedBalance

# read the raw transaction from the node
transaction: Transaction = web3provider.get_full_transaction('0x50051e0a6f216ab9484c2080001c7e12d5138250acee1f4b7c725b8fb6bb922d')

# decode transaction components
abi_decoded_events: List[Event] = ethtx.decoders.abi_decoder.decode_events(transaction.events, transaction.metadata)
abi_decoded_calls: DecodedCall = ethtx.decoders.abi_decoder.decode_calls(transaction.root_call, transaction.metadata)
abi_decoded_transfers: List[DecodedTransfer] = ethtx.decoders.abi_decoder.decode_transfers(abi_decoded_calls, abi_decoded_events)
abi_decoded_balances: List[DecodedBalance] = ethtx.decoders.abi_decoder.decode_balances(abi_decoded_transfers)

# decode a single event
raw_event: Event = transaction.events[3]
abi_decoded_event: DecodedEvent = ethtx.decoders.abi_decoder.decode_event(raw_event, transaction.metadata)

# decode a single call
raw_call: Call = transaction.root_call.subcalls[3].subcalls[2]
abi_decoded_call: DecodedCall = ethtx.decoders.abi_decoder.decode_call(raw_call, transaction.metadata)
  1. Semantic decoding:
from ethtx.models.decoded_model import DecodedTransactionMetadata

# get proxies used in the transaction
proxies = ethtx.decoders.get_proxies(transaction.root_call)

# semantically decode transaction components
decoded_metadata: DecodedTransactionMetadata = ethtx.decoders.semantic_decoder.decode_metadata(block.metadata, transaction.metadata)
decoded_events: List[DecodedEvent] = ethtx.decoders.semantic_decoder.decode_events(abi_decoded_events, decoded_metadata, token_proxies)
decoded_calls: Call = ethtx.decoders.semantic_decoder.decode_calls(abi_decoded_calls, decoded_metadata, proxies)
decoded_transfers: List[DecodedTransfer] = ethtx.decoders.semantic_decoder.decode_transfers(abi_decoded_transfers)
decoded_balances: List[DecodedBalance] = ethtx.decoders.semantic_decoder.decode_balances(abi_decoded_balances)

# semantically decode a single event
decoded_event: DecodedEvent = ethtx.decoders.semantic_decoder.decode_event(abi_decoded_events[0], decoded_metadata, proxies)
# semantically decode a single call
decoded_call: Call = ethtx.decoders.semantic_decoder.decode_call(abi_decoded_calls.subcalls[2].subcalls[0], decoded_metadata, proxies)
Comments
  • No module named 'ethtx.semantics'

    No module named 'ethtx.semantics'

    Windows 10. Python version 3.10.4. Latest version for ethtx is installed with pip install ethtx.

    I created a file test.py with the following content:

    from ethtx import EthTx, EthTxConfig
from ethtx.models.decoded_model import DecodedTransaction

ethtx_config = EthTxConfig(
    etherscan_api_key="my etherscan API key",  ##Etherscan API key,
    web3nodes={
        "mainnet": {
            "hook": "my Infura url",  # multiple nodes supported, separate them with comma
            "poa": False  # represented by bool value
        }
    },
    default_chain="mainnet",
    etherscan_urls={"mainnet": "https://api.etherscan.io/api" }
)

ethtx = EthTx.initialize(ethtx_config)
transaction: DecodedTransaction = ethtx.decoders.decode_transaction(
    '0x50051e0a6f216ab9484c2080001c7e12d5138250acee1f4b7c725b8fb6bb922d')

    Once I try to execute the file with py test.py, I get the following error:

    What's the issue? Thanks for the help.

    When debug, I found from_address is set to none in ethtx/providers/web3_provider.py , 479 line.

    I have no idea why? And I print the debug_transaction response , it dose not contain from_address , either.

    I think maybe L194

    value=call.call_value / 10**18,

    could be replaced by

    value=Decimal(call.call_value) / 10**18,

    and a import should also be added.

    I will push a PR soon

  • Getting started script not working

    Getting started script not working

    Just discovered this repo. Really interested to test it out.

    However, when I tried to run the 'Getting started1' script in README, I came across a few errors:

    Error 1:

    File "test.py", line 6
    mongo_database = "mongomock://localhost"
    ^
SyntaxError: invalid syntax

    I got passed this by adding commas before each inline comment. Then I got another error:

    Error 2:

    Traceback (most recent call last):
  File "test.py", line 4, in <module>
    ethtx_config = EthTxConfig(
TypeError: __init__() got an unexpected keyword argument 'mongo_database'

    I looked into ethtx.py and didn't see any mongo_database attribute. So I commented the mongo_database line out. Then I got another error:

    Error 3:

    Traceback (most recent call last):
  File "test.py", line 18, in <module>
    ethtx = EthTx.initialize(ethtx_config)

    raise ConfigurationError('No default database name defined or provided.')
pymongo.errors.ConfigurationError: No default database name defined or provided.

    Can you advise if I am doing something incorrectly? Thanks.

  • Account balances not adding up for Eth for USDT transaction on UniswapV3

    Account balances not adding up for Eth for USDT transaction on UniswapV3

    So it seems that there is some bug with how multicalls are being handled.

    here https://etherscan.io/tx/0x093cdad6594e26543fdec775ddb99c6a761bace9512332a5aec50b38b39e92d9

    You see that I have received $126 USDT for .1 eth.

    However then the transaction is analyzed it does not seem to reflect that: https://ethtx.info/mainnet/0x093cdad6594e26543fdec775ddb99c6a761bace9512332a5aec50b38b39e92d9/

    Other tool seems to handle this better https://phalcon.blocksec.com/tx/eth/0x093cdad6594e26543fdec775ddb99c6a761bace9512332a5aec50b38b39e92d9.

    Anyone know if this is a bug... or am i just misinterpreting the result.

  • Fix loss of precision decimal numbers

    Fix loss of precision decimal numbers

    Fixed the issue of loss of precision in the decimal representation of large floats. Converted float to Decimals and changed the precision of the context to 256 i.e. getcontext().prec = 256. Eventually returns the string representation of the Decimal object.

    This fixes the issue of scientific notation representation of floats both in Argument value field and also other fields in models from decoded_model.py

  • ENS lookup bug

    ENS lookup bug

    I was comparing ethtx output to other similar tools and found a case where ethtx resolves an incorrect ENS address.

    In ethtx.info, the offerer value is babywhale.eth. Clicking on babywhale.eth in ethtx uses the address 0x8af6e15ed513b5b73573f58158b1b0bbd5085ec7. But babywhale.eth on etherscan resolves to 0x9bf2eb61a3beb7afb1213029f3f1ae3e08ede755 https://ethtx.info/mainnet/0x665c4db0b7dcf44eb2ead3d455b12bfb244de9a2d3239d756ca3fbdbf21817bb/

    Meanwhile, two other transaction explorers (which don't support ENS resolution) show the value 0x8af6e15ed513b5b73573f58158b1b0bbd5085ec7 for the offerer https://phalcon.blocksec.com/tx/eth/0x665c4db0b7dcf44eb2ead3d455b12bfb244de9a2d3239d756ca3fbdbf21817bb https://tx.eth.samczsun.com/ethereum/0x665c4db0b7dcf44eb2ead3d455b12bfb244de9a2d3239d756ca3fbdbf21817bb

    0x8af6e15ed513b5b73573f58158b1b0bbd5085ec7 does hold two ENS addresses, but babywhale.eth is not one of them, so the wrong ENS address is getting displayed.

  • More flexible dependencies, no cursor timeout, cache 4bytes

    More flexible dependencies, no cursor timeout, cache 4bytes

    • Make more flexible deps - ethtx is easier to install in other apps
    • No timeout for mongo cursor - some collections may sometimes require more time to search
    • Cache 4bytes resposne, if some transactions have a lot of guessed functions/events, it definitely speeds up ethtx!

  • Bug in tx data decoding (token transfers & account balances sections)

    Bug in tx data decoding (token transfers & account balances sections)

    Referring to this tx on etherscan, address 0x8c3FA50473065f1D90f186cA8ba1Aa76Aee409Bb is receiving 0.01 eth but as per the tx on ethtx.info the address is sending out the same amount.

    The emitted events show it as a donation sent event which would indicate the aforementioned address should be the recipient of the amount rather than the one sending it, and hence, I'm inclined to believe that the decoding on etherscan is correct and ethtx's isn't.

    I tried to make some more sense of the data and these points might help with debugging the issue: 0x8c3f.. is a gnosis safe multisig. Ethtx shows 0x8c3f.. is sending the eth to 0x34cf.., this recipient is actually the gnosis safe mastercopy contract. I think this is where the problem lies. this mastercopy be receiving the funds from the multisig doesn't seem right to me
