Blockchain Wallet Similarity Engine

Overview#

The Blockchain Wallet Similarity Engine employs sophisticated behavioral analysis and pattern matching to identify related wallets, detect coordinated activity, and uncover hidden entity relationships across blockchain networks. By combining multiple analysis dimensions, the system achieves high accuracy in identifying wallet clusters belonging to the same controlling entity, significantly reducing investigation time while uncovering more related addresses than traditional heuristic methods.

Key Features#

Multi-Dimensional Similarity Scoring - Combines six analysis dimensions (transaction patterns, temporal behavior, counterparty overlap, gas usage profiling, smart contract interactions, and entity co-occurrence) into an overall similarity score (0-100)
Transaction Pattern Fingerprinting - Creates unique behavioral fingerprints for wallets based on transaction amounts, frequencies, counterparty distributions, and operational patterns
Temporal Behavior Correlation - Analyzes activity timing patterns to identify wallets operated on the same schedule, time zone, or by the same automation systems
Counterparty Overlap Analysis - Identifies wallets that transact with the same set of counterparties, indicating shared relationships or common control
Gas Usage Profiling - Detects wallet software signatures through gas price preferences, gas limit patterns, and transaction construction characteristics
Smart Contract Interaction Patterns - Compares DeFi protocol usage, token preferences, and contract interaction sequences to establish behavioral similarity
Real-Time Similarity Queries - Low-latency scoring enables instant investigation expansion from known addresses to related wallets
Continuous Learning - Machine learning models continuously improve through observed entity resolutions and validated similarity assessments

Supported Networks#

Major Blockchains: Bitcoin, Ethereum, Tron, BNB Chain, Solana, Cardano, Polkadot, Avalanche
Layer 2 Solutions: Polygon, Arbitrum, Optimism, Base, zkSync Era, Starknet, Linea
EVM-Compatible Chains: Cronos, Moonbeam, Fantom, Gnosis Chain, Aurora, Celo, and more
Additional Networks: Ripple, Stellar, Algorand, Cosmos, Near, Tezos

Similarity Score Interpretation#

Very High (90-100) - Almost certainly the same entity; multiple strong behavioral matches across dimensions
High (75-89) - Strong evidence of common control; suitable for investigative expansion and enhanced due diligence
Moderate (50-74) - Notable similarities warranting investigation; may represent same entity or similar operational patterns
Low (25-49) - Weak similarities; may be coincidental or reflect common behavioral patterns across unrelated entities
Minimal (0-24) - No meaningful behavioral similarity detected

Investigation Use Cases#

Entity Expansion#

Starting from a single known address, discover all related wallets controlled by the same entity
Expand investigation scope beyond traditional clustering by incorporating behavioral analysis
Identify operational wallets, reserve wallets, and test wallets belonging to the same entity

Coordinated Activity Detection#

Detect sybil attacks where a single entity operates multiple wallets to manipulate markets or governance
Identify coordinated wash trading across apparently unrelated addresses
Uncover pump-and-dump coordination through synchronized behavioral patterns

Money Laundering Investigation#

Identify when a single entity operates multiple wallets to structure transactions below reporting thresholds
Detect related wallets used in layering schemes where funds are distributed and reconsolidated
Connect mixing service input and output addresses through pre/post-mixing behavioral consistency

Fraud Network Mapping#

Map the complete wallet infrastructure of fraud operations from a single known address
Identify accomplice wallets through behavioral similarity to known fraudulent addresses
Detect new fraud wallets being established by previously identified scam operators

Exchange Compliance#

Identify when multiple customer accounts are controlled by the same entity to detect market manipulation or sanctions evasion
Enhance Know Your Customer processes with behavioral entity linking
Detect attempts to create multiple accounts to circumvent trading limits or sanctions controls

Threat Actor Attribution#

Link new wallets to known threat actors through behavioral fingerprint matching
Identify when threat actors create fresh wallets by detecting operational pattern continuity
Connect ransomware payment wallets to operator infrastructure through behavioral similarity

Analysis Dimensions#

Transaction Pattern Analysis#
