Community version of EthTx transaction decoder
https://ethtx.info

This project represents usage of EthTx decoding library in form of a website. If you are looking for implementation of the said decoding functionalities, please refer to EthTx repository.

Here is a list of steps to recreate local environment on Ubuntu distribution.

1. Install needed packages using apt:

   apt install docker-compose python3-pip python3-dev pipenv make
   apt install libxml2-dev libxslt1-dev gcc

2. Run:

   pipenv install

3. Copy .env_sample to .env and fill required field according to description

     # Proper nodes are required to run ethtx, provide connection strings for chains which will be used.
     MAINNET_NODE_URL=https://geth-erigon-node:8545
     # KOVAN_NODE_URL=
     # RINKEBY_NODE_URL=
   
     # EthTx supports multiple nodes, if one is unavailable, it will use others. You only need to specify them with a comma
     # Example: MAINNET_NODE_URL=https://geth-erigon-node:8545,https://geth1-erigon-node:8545
   
   
     # Etherscan API is used to get contract source code, required for decoding process
     # You can get free key here https://etherscan.io/apis
     ETHERSCAN_KEY=
   
     # Optional. Those represent data required for connecting to mongoDB. It's used for caching semantics
     # used in decoding process. But, it's not neccessary for running, If you don't want to use permanent
     # db or setup mongo, leave those values, mongomock package is used to simulate in-memory mongo.
     MONGO_CONNECTION_STRING=mongomock://localhost/ethtx
   
     # Optional. Credentials for accessing semantics editor page, available under '/semantics/<str:address>'
     ETHTX_ADMIN_USERNAME=admin
     ETHTX_ADMIN_PASSWORD=admin
   
     # Optional. Api key used for exposing
     API_KEY=
   
     # Optional. Valid values are ['production', 'staging', 'development']. Those mainly
     # dictate what options are used for flask debugging and logging
     ENV=development
   

4. Run

   PYTHONPATH=./ethtx_ce FLASK_APP=ethtx_ce/app/wsgi.py pipenv run flask run --host=0.0.0.0 --port 5000

   or

   make run-local

   This will setup new server on host 0.0.0.0 port 5000.

5. Now ethtx_ce should be accessible through link http://localhost:5000

Use can also provided docker-compose for running this locally:

docker-compose up

Note, this also need proper .env file to function properly.

For proper functioning, .env file is required containing all database and 3rd party providers configuration. .env_sample file is provided in repository with example values.

Parameters [CHAIN_ID]_NODE_URL should hold valid urls to ethereum nodes; Parameter ETHERSCAN_KEY should be equal to Etherscan API key assigned to user.

The EthTx APIs are provided as a community service and without warranty, so please use what you need and no more. We support GET requests.
