On 2026-04-28 ChainAnalyzer landed its first mainnet x402 settlement: an AI agent paid $0.008 USDC on Base via the Coinbase CDP Facilitator and got back a CRITICAL verdict on a Tornado Cash address with 64 detections — no account, no API key, all on-chain. Five implementation pitfalls (verify wire format, missing settle, X-PAYMENT proxy stripping, esm.sh deps, self-transfer) and how we fixed them.

We expanded ChainAnalyzer from 5 chains to 9 in a single sprint without paying a cent more in API fees. The trick: Etherscan V2's chainid-routed unified API and a one-line refactor to put chain config behind a single registry. ChainAnalyzer = 9 chains with Bitcoin vs. ChainAware = 8 chains without Bitcoin. Here's the actual diff.

Most MCP servers expose tools for free and trust the caller. We wanted ours to charge per call without a human in the loop. Here's how we wired Claude → MCP tool → HTTP 402 → EIP-3009 USDC settlement on Base, end-to-end, so an AI agent can buy AML risk data on demand. No accounts, no API keys, the agent's wallet is the budget.

ChainAnalyzer's MCP server is now officially listed on awesome-mcp-servers (community-curated directory), earned a AAA score on Glama (security/license/quality all A), and is registered on the official MCP Registry. x402 USDC settlement now lives on Base and Solana mainnet via the Coinbase CDP Facilitator, with Coinbase Bazaar / Agentic.Market auto-discovery enabled.

In February 2026 we uncovered a $5.3M cross-chain address poisoning network with 264+ operators and a single Master Funder. Today we went back to see what happened. 854 new operator wallets. $16.8M USDT processed by the ETH collector. The operation did not stop — it accelerated.

The founder of ChainAnalyzer got drained by a fake Orynth airdrop with an admin badge. That $7.95 lesson became the first entry in our ScamDB and the origin story of a platform now covering Bitcoin, Ethereum, Polygon, Avalanche, and Solana with 76+ detection rules and MCP integration.

ChainAnalyzer now officially supports AML analysis for JPYC (Japanese yen-pegged stablecoin), USDT, USDC, PYUSD, and FDUSD. Pre-transfer screening, FATF Travel Rule threshold detection, and Japan-regulatory-ready compliance evidence — all delivered in native Japanese.

Follow laundered funds across chains: ChainAnalyzer now auto-detects bridge hops through Wormhole, LayerZero, Across, Stargate, deBridge, and NEAR Intents with 3 detection methods (event logs, calldata, memo-based). Essential for cross-chain AML investigations. Pro plan.

ChainAnalyzer now offers a public REST API for programmatic address scanning and a free ScamDB lookup API. Generate tfk_ API keys, scan addresses across 9 chains, query our scam database, and export enriched batch reports as PDF.

New feature: Machine learning models (Isolation Forest + AutoEncoder + GraphSAGE) analyze Neo4j transaction graphs to detect anomalous wallet behavior that rule-based checks may miss. Complements 76+ detection rules across 9 chains.

Continuous token-contract surveillance: register USDT, USDC, JPYC, or any ERC-20 / SPL contract and let ChainAnalyzer flag address poisoning, relay chains, rapid distribution, statistical outlier transfers, and known-malicious sender patterns with email / webhook alerts. Pro+.

New Watchlist feature: Follow Mode automatically explores the transaction graph of watched addresses and discovers related wallets with high-risk activity. Catch drainers when they move to new wallets.

Export your scan results as professional PDF reports. Includes risk score, all detection findings, transaction graph data, and detailed analysis. Perfect for compliance documentation and sharing with stakeholders.

ChainAnalyzer now supports 5 blockchains (Bitcoin, Ethereum, Avalanche, Polygon, Solana) with 62+ detection checks. Scan for sanctions, mixers, peel chains, token relay patterns, dust attacks, CoinJoin, and more.

New feature: Connect your Phantom wallet and scan all SPL token holdings for rug pulls, drainers, and honeypots in one click. Available on Starter and Pro plans.

Introducing ChainAnalyzer - detect rug pulls, wallet drainers, honeypots, whale concentration, and LP vulnerabilities on Solana. Scan any SPL token in 30 seconds.

Spot rug pulls before buying: ChainAnalyzer auto-detects active mint/freeze authority, unlocked liquidity pools, whale concentration, and supply-manipulation risks on any SPL or EVM token — CRITICAL/HIGH verdict in 30 seconds.

New feature: Detect known wallet drainers and phishing tokens using our ScamDB. Built from real-world experience after our developer fell victim to a drainer.
