On-Chain Analysis Platform — 9-Chain Blockchain Analytics SaaS

On-chain analysis is the discipline of extracting fund-flow, behavioral, and risk signals directly from public blockchain transaction data. ChainAnalyzer is a Japan-built end-to-end on-chain analysis platform (refinancier, inc.) covering 9 blockchains in a single API and SaaS, with Neo4j graph analysis, a 3-model ML ensemble, 76+ AML detection rules, and AI-agent integration.

What on-chain analysis actually involves

Public blockchains (Bitcoin, Ethereum, etc.) record every transaction permanently and openly. On-chain analysis turns that raw stream into useful artifacts:

  • Fund-flow tracing — graph traversal upstream / downstream, surfacing related addresses
  • Risk scoring — sanctions, mixer, drainer, scam involvement classification
  • Behavioral analysis — whale concentration, hold/sell trends, liquidity changes, arbitrage patterns
  • Entity clustering — grouping multiple addresses controlled by the same operator
  • Anomaly detection — ML to flag transactions outside the baseline distribution
  • Compliance evidence — collecting audit trails for AML / KYT / FATF Travel Rule / SAR filings

Core technical stack of an on-chain analysis platform

  1. RPC / indexers — Etherscan, Alchemy, Helius, Blockstream Esplora pull transaction data
  2. Graph database — Neo4j or equivalent stores "address → tx → address" relationships for efficient traversal
  3. Heuristic detectors — rule-based identification of known illicit patterns
  4. Machine learning — unsupervised anomaly detection (Isolation Forest, AutoEncoder) plus graph ML (GraphSAGE)
  5. OSINT integration — Reddit, X, GitHub, ScamDB enrich the on-chain signal with off-chain context
  6. Reporting — PDF / JSON / Webhook output for internal teams, partners, or regulators

The ChainAnalyzer engine

Neo4j graph expansion (Follow Mode)

Watched addresses are expanded 1-3 hops via BFS, and related suspicious addresses are surfaced automatically — the direct functional analogue of Chainalysis Reactor's pivot. Follow Mode details.

3-model ML ensemble (anomaly scoring)

Rules miss novel patterns. We combine three ML models into a 0-1 anomaly score:

  • Isolation Forest — statistical outlier detection
  • AutoEncoder — reconstruction error as anomaly signal
  • GraphSAGE — Neo4j subgraph topology embedding

See ML scoring writeup.

76+ heuristic detection rules

Chain-specific rule sets for EVM, Solana, and Bitcoin: address poisoning (we discovered a $5.3M operating ring), peel chain, drainer, rug-pull, and more. All 76+ detection rules.

Cross-chain bridge tracing

Six bridges detected via three methods (event log, calldata, memo): Wormhole, LayerZero, Stargate, deBridge, Across, NEAR Intents. Bridge investigation feature.

Real-world usage

  • Crypto exchanges — deposit / withdrawal AML screening, suspicious activity reporting
  • Institutional investors — counterparty risk assessment (OTC, DeFi)
  • Audit firms / compliance consultants — AML program audits, PDF deliverables
  • Law enforcement — seized-asset tracing, criminal-network visualization
  • Security researchers — drainer / scam network analysis, vulnerability reports
  • AI agents — autonomous counterparty screening via x402 (no subscription)
