Shared constants and utilities for ChainSwarm blockchain analytics projects

chainswarm-core

Shared constants and utilities for ChainSwarm blockchain analytics projects.

Overview

chainswarm-core provides a single source of truth for:

• Blockchain network definitions - Network types, block times, native assets
• Address classifications - Address types, trust levels, risk mappings
• Pattern detection constants - Pattern types, detection methods, role classifications
• Database utilities - ClickHouse repository base class and row conversion utilities

This package eliminates code duplication across ChainSwarm projects including:

• data-pipeline
• chain-synthetics
• analytics-pipeline
• ml-pipeline
• benchmark
• risk-scoring

Installation

pip install chainswarm-core

For development:

pip install chainswarm-core[dev]

Quick Start

from chainswarm_core import (
    AddressTypes,
    Network,
    NetworkType,
    RiskLevels,
    TrustLevels,
)

# Check network type
if Network.get_node_type("polkadot") == NetworkType.SUBSTRATE:
    print("Polkadot is a Substrate network")

# Get block time
block_time = Network.get_block_time("bitcoin")  # Returns 600 seconds

# Check address risk
from chainswarm_core.constants import get_address_type_risk_level, is_high_risk_address_type

risk = get_address_type_risk_level(AddressTypes.MIXER)  # Returns "critical"
is_risky = is_high_risk_address_type(AddressTypes.GAMBLING)  # Returns True

Modules

chainswarm_core.constants.networks

Network type classifications and blockchain network enum.

from chainswarm_core.constants.networks import (
    NetworkType,      # SUBSTRATE, EVM, UTXO
    Network,          # Enum of supported networks
    substrate_networks,
    evm_networks,
    utxo_networks,
)

# Get native asset symbol
symbol = Network.get_native_asset_symbol("bittensor")  # Returns "TAO"

chainswarm_core.constants.addresses

Address type and trust level classifications.

from chainswarm_core.constants.addresses import (
    AddressTypes,     # EXCHANGE, DEX, MIXER, VALIDATOR, etc.
    TrustLevels,      # VERIFIED, COMMUNITY, OFFICIAL, etc.
    is_high_risk_address_type,
    is_trusted_address_type,
)

chainswarm_core.constants.risk

Risk levels, severities, and risk mappings.

from chainswarm_core.constants.risk import (
    RiskLevels,       # LOW, MEDIUM, HIGH, CRITICAL
    Severities,       # LOW, MEDIUM, HIGH, CRITICAL
    ADDRESS_TYPE_RISK_MAP,
    AddressSubtypeRiskModifiers,
    get_address_type_risk_level,
    get_subtype_risk_modifier,
)

# Get risk level for address type
risk = get_address_type_risk_level(AddressTypes.SCAM)  # Returns "critical"

# Get risk modifier for subtype
modifier = get_subtype_risk_modifier("uniswap_v3")  # Returns 0.8

chainswarm_core.constants.patterns

Pattern detection types and role classifications.

from chainswarm_core.constants.patterns import (
    PatternTypes,     # CYCLE, LAYERING_PATH, SMURFING_NETWORK, etc.
    DetectionMethods, # SCC_ANALYSIS, CYCLE_DETECTION, etc.
    PatternRoles,     # ATTACKER, MULE, HOT_WALLET, etc.
    MALICIOUS_ROLES,
    VICTIM_ROLES,
    BENIGN_ROLES,
    is_malicious_role,
    is_victim_role,
    is_benign_role,
)

chainswarm_core.db

ClickHouse database utilities.

from chainswarm_core.db import (
    BaseRepository,
    row_to_dict,
    convert_clickhouse_enum,
    clickhouse_row_to_pydantic,
    rows_to_pydantic_list,
)

# Create a repository
class MyRepository(BaseRepository):
    @classmethod
    def schema(cls) -> str:
        return "my_table.sql"
    
    @classmethod
    def table_name(cls) -> str:
        return "my_table"

# Convert rows to Pydantic models
from pydantic import BaseModel

class MyModel(BaseModel):
    id: int
    name: str

rows = [(1, "first"), (2, "second")]
columns = ["id", "name"]
models = rows_to_pydantic_list(MyModel, rows, columns)

Migration Guide

From project-local constants

Before:

from packages.storage.constants import AddressTypes, RiskLevels
from packages.storage.repositories.base_repository import BaseRepository

After:

from chainswarm_core import AddressTypes, RiskLevels, BaseRepository

From project-local repository utils

Before:

from packages.storage.repositories.utils import row_to_dict

After:

from chainswarm_core.db import row_to_dict

Development
