Crypto AML — Blockchain Anti-Money-Laundering Platform & On-Chain Analysis

On this page, "AML" refers to Anti-Money Laundering — specifically, the prevention of illicit fund flows on blockchains and crypto assets. ChainAnalyzer is a multi-chain crypto AML SaaS, built by refinancier, inc., delivering on-chain analysis and transaction monitoring across nine blockchains in a single API and dashboard, hosted on Azure Japan East with a native Japanese UI for the Japanese market.

What crypto AML actually covers (3-minute primer)

Crypto AML is the continuous monitoring and detection of money laundering on blockchains. Concretely, the work breaks down into:

  • Transaction monitoring — risk-scoring counterparty addresses, surfacing suspicious activity
  • Sanctions screening — OFAC SDN, UN, EU, JFSA, and equivalent national lists
  • Travel Rule compliance — FATF Recommendation 16; sender / receiver info exchange above $3,000 equivalent
  • Case management — investigation records and PDF audit trails for SAR / STR filings
  • On-chain analysis — graph traversal to surface related suspicious addresses

Why a multi-chain AML stack matters now

Illicit fund flows do not respect chain boundaries. A drainer typically lands stolen ETH on Ethereum, bridges to Polygon or Arbitrum to evade frozen mixer pools, then converts to a stablecoin via a low-liquidity DEX. Single-chain AML tools see the start and stop but miss the middle. ChainAnalyzer covers Bitcoin, Ethereum, Polygon, BNB Chain, Base, Arbitrum, Optimism, Avalanche, and Solana, and detects bridge hops via Wormhole, LayerZero, Stargate, deBridge, NEAR Intents, and Across.

Risk patterns we cover

  • Sanctioned addresses — Tornado Cash, OFAC-designated wallets
  • Mixer / CoinJoin usage — Wasabi, JoinMarket, Tornado Cash interaction history
  • Peel chain — incremental small-amount fragmentation, the classic obfuscation play
  • Address poisoning — injecting look-alike addresses into transaction history
  • Wallet drainers — fake-dApp signature exploits (especially prevalent on Solana)
  • Rug pulls / honeypots — post-launch liquidity removal, sell-blocking
  • Cross-chain laundering — funds moved through Wormhole / LayerZero / Stargate / deBridge

The 76+ detection rules cover all of the above; the 3-model ML ensemble (Isolation Forest + AutoEncoder + GraphSAGE) catches novel patterns the rules miss.

Stablecoin AML monitoring — JPYC, USDT, USDC, PYUSD, FDUSD

Stablecoin volumes now dominate cross-chain transfers. ChainAnalyzer monitors:

  • JPYC (Japanese yen stablecoin) — full coverage on Polygon and Ethereum
  • USDT (Tether) — Ethereum, Polygon, Avalanche, BSC, Arbitrum, Optimism, Solana
  • USDC — Ethereum, Polygon, Avalanche, BSC, Base, Arbitrum, Optimism, Solana
  • PYUSD (PayPal USD) — Ethereum, Solana
  • FDUSD — Ethereum, BSC

Three integration paths

  1. Web SaaS — browser-based scanning, Case Management, PDF reports ($4.99–$19.99/mo)
  2. REST API — embed into existing systems (tfk_ API key, Pro+)
  3. x402 / MCP — pay-per-call ($0.008 USDC), no subscription, ideal for AI agents

Positioning vs. Chainalysis Reactor / KYT

Chainalysis is the legacy industry standard, but the entry price ($25K+/year) and English-only UI create friction for the Japanese market. ChainAnalyzer offers comparable investigation surface (Case Management, Follow Mode, ML scoring) at roughly 1/10 the cost with a native Japanese UI.
