How this service works
Multi-chain blockchain AML and security intelligence platform for tokens, wallets, and stablecoins. Detect sanctions, money laundering, rug pulls, drainers, and stablecoin flow risks across 8 chains live (Bitcoin, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, Solana) plus BNB Smart Chain on Enterprise rollout. Stablecoin AML coverage for JPYC, USDT, USDC, PYUSD, FDUSD with FATF Travel Rule screening.
Output
Returns the full trace of the transaction (as an array of on-chain steps), an anomaly score (numeric, higher = riskier), the list of counterparties involved, the chain identifier, and the echoed tx hash — enabling downstream AML review, sanctions screening, or compliance reporting.
Example use cases
Due diligence screening for payment processor
“We just received a large USDC deposit from a customer. Can you trace the transaction back through the blockchain and flag any money laundering risks, sanctions connections, or suspicious counterparties involved?”
Fraud investigation across DeFi protocols
“We're investigating a suspected rug pull. Can you trace this Polygon transaction hash and show me the full flow of funds—where the money went, who moved it, and whether the activity looks anomalous or matches drainer patterns?”
Stablecoin compliance monitoring for treasury
“Before we accept this incoming stablecoin transfer on Arbitrum, can you check if it's linked to any high-risk wallets, trace its recent history, and give me a risk score so I know if it meets our FATF Travel Rule requirements?”

Endpoint
GEThttps://chain-analyzer.com/x402/api/tx/0x0000000000000000000000000000000000000000000000000000000000000000/traceWhen to prefer
Use this endpoint when you need to trace the full counterparty graph and anomaly score for a specific transaction hash across any of the 8 supported chains (Bitcoin, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, Solana). Prefer this over address-level AML endpoints when your investigation starts from a tx hash rather than a wallet address, and you need fund-flow tracing with stablecoin and FATF Travel Rule context.
Side effects
- Invalid or non-existent tx hash returns an error or empty trace
- Transaction not yet indexed (too recent) may return incomplete data
- Unsupported chain or chain not yet live returns an error
- Payment not processed correctly results in 402 response with no data
- Rate limiting or quota exhaustion returns a 429 or similar error
