EVM Contracts

Description

EVMC (Ethereum Virtual Machine Contracts) is a collection of smart contracts from the ETH blockchain.

In particular, each sample holds the creation and runtime bytecodes. When available, the sources are also included.

HEX Dataset

Config	Split	Size	Samples	Blocks
'hex-ethereum'	'train'	2.8 GB	1,294,247	19,493,000 - 20,292,000
'hex-ethereum'	'cleaned'	2.0 GB	122,800	19,493,000 - 20,292,000

The "cleaned" split covers the same block range, but records were removed when:

• the source code is not available
• the source code matches the contract factory instead of the deployed contract

BIN Dataset

Config	Split	Size	Samples	Blocks
'bin-ethereum'	'train'	2.3 GB	1,294,247	19,493,000 - 20,292,000

Features

The data comes in two flavors: binary and hexadecimal encodings. The fields have the same names in both and the underlying data is also identical.

In binary form, the raw bytes are stored in most fields:

datasets.Features({
    'chain_id': datasets.features.Value(dtype='uint64'),
    'block_number': datasets.features.Value(dtype='uint64'),
    'block_hash': datasets.features.Value(dtype='large_binary'),
    'transaction_hash': datasets.features.Value(dtype='large_binary'),
    'deployer_address': datasets.features.Value(dtype='large_binary'),
    'factory_address': datasets.features.Value(dtype='large_binary'),
    'contract_address': datasets.features.Value(dtype='large_binary'),
    'creation_bytecode': datasets.features.Value(dtype='large_binary'),
    'runtime_bytecode': datasets.features.Value(dtype='large_binary'),
    'creation_sourcecode': datasets.features.Value(dtype='large_binary'),})

While in hexadecimal format, the data is encoded into HEX strings:

datasets.Features({
    'chain_id': datasets.features.Value(dtype='uint64'),
    'block_number': datasets.features.Value(dtype='uint64'),
    'block_hash': datasets.features.Value(dtype='string'),
    'transaction_hash': datasets.features.Value(dtype='string'),
    'deployer_address': datasets.features.Value(dtype='string'),
    'factory_address': datasets.features.Value(dtype='string'),
    'contract_address': datasets.features.Value(dtype='string'),
    'creation_bytecode': datasets.features.Value(dtype='string'),
    'runtime_bytecode': datasets.features.Value(dtype='string'),
    'creation_sourcecode': datasets.features.Value(dtype='string'),})

Chain And Block Numbers

Both ids are stored as unsigned integers.

Solidity Sources

The sources all have open source licenses. They were collected from block explorer APIs like Etherscan.

The sources are formatted as standard JSON input for the solidity compiler.

The resulting JSON is then encoded using UTF-8 into a single string.

HEX Dataset

All the other features are HEX encoded into strings, without the 0x prefix.

For example:

{
    'chain_id': 1,
    'block_number': 20155815,
    'block_hash': 'fcddf33b1b5a728a40588eda60262639201ac0d3f611f08286a9e2ef65576111',
    'transaction_hash': 'ec3723ffb8a3bbb8b83b25481f61cbfc46383fc88ff8eb364186b53aa226e4bf'
    'deployer_address': 'ba57abe375903838b5c19709e96dae12191fa37e',
    'factory_address': '0000000000b3f879cb30fe243b4dfee438691c04',
    'contract_address': 'eff10e7d4feef60ed9b9e9bb9fee12c2504bd0ba',
    'creation_bytecode': '756eb3f879cb30fe243b4dfee438691c043318585733ff6000526016600af3',
    'runtime_bytecode': '6eb3f879cb30fe243b4dfee438691c043318585733ff',
    'solidity_sourcecode': '',}

BIN Dataset

All the other features are stored in binary format:

{
    'chain_id': 1,
    'block_number': 20155815,
    'block_hash': b'\xfc\xdd\xf3;\x1bZr\x8a@X\x8e\xda`&&9 \x1a\xc0\xd3\xf6\x11\xf0\x82\x86\xa9\xe2\xefeWa\x11',
    'transaction_hash': b'\xec7#\xff\xb8\xa3\xbb\xb8\xb8;%H\x1fa\xcb\xfcF8?\xc8\x8f\xf8\xeb6A\x86\xb5:\xa2&\xe4\xbf',
    'deployer_address': b'\xbaW\xab\xe3u\x9088\xb5\xc1\x97\t\xe9m\xae\x12\x19\x1f\xa3~',
    'factory_address': b'\x00\x00\x00\x00\x00\xb3\xf8y\xcb0\xfe$;M\xfe\xe48i\x1c\x04',
    'contract_address': b'\xc7%\xbc1\xcb\xa2LS\xe5\xc0\xc2\xe2\x06]K@\xf5#Fx',
    'creation_bytecode': b'un\xb3\xf8y\xcb0\xfe$;M\xfe\xe48i\x1c\x043\x18XW3\xff`\x00R`\x16`\n\xf3',
    'runtime_bytecode': b'n\xb3\xf8y\xcb0\xfe$;M\xfe\xe48i\x1c\x043\x18XW3\xff',
    'creation_sourcecode': b''}

This saves disk space and may actually be more practical for further processing.
