9 blockchains supported: Base, Arbitrum, Optimism and BNB Smart Chain join the lineup
Update (Aug 2026): This post reflects our April 2026 lineup. Since then we've added Kaia, TRON, and XRP — ChainAnalyzer now supports 12 chains on every plan. See docs/chains for the current list.
On 2026-04-28, ChainAnalyzer expanded its supported set from 5 chains to 9. The new additions are BNB Smart Chain, Base, Arbitrum, and Optimism. Base / Arbitrum / Optimism / Avalanche are available for scanning right away on Free / Starter / Pro / x402, and BNB Smart Chain rolls out on the Enterprise plan.
Highlights
- 9 supported chains: Bitcoin, Ethereum, Polygon, Avalanche, Solana plus BNB Smart Chain / Base / Arbitrum / Optimism
- 8 chains available right away: Bitcoin, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, Solana
- BNB Smart Chain rolling out on Enterprise
- All 76+ detection rules run on the new chains unchanged — the same criteria apply across chains
- EVM breadth without giving up Bitcoin — chain breadth plus Bitcoin coverage is a rarer combination among multi-chain AML tools than you'd expect
Why chain count matters
The first filter anyone applies when choosing a tool is "does it cover the chain I work with?". If you need to trace funds on Optimism, a tool without Optimism doesn't make your list. And illicit funds rarely stay on one chain — coverage breadth directly determines how far an investigation can reach.
This expansion was done with one constraint: broaden the chain count without losing the Bitcoin support that's our actual differentiator. Few tools let you investigate Bitcoin and the EVM chains side by side in one dashboard.
What you can do on the new chains
On all four new chains, address scanning, risk detection, Neo4j graph analysis, and PDF reports work exactly as they do everywhere else. The 76+ detection rules are chain-agnostic by design, so the same criteria apply on the new chains. Native-token differences (ETH on Base / Arbitrum / Optimism, BNB on BNB Smart Chain) are handled correctly in transfer valuations.
Engineering note: how four chains shipped at once
Two things made this expansion fast. First, data retrieval for the EVM chains — which share an Etherscan-compatible API surface — is unified into a single pipeline. Second, all per-chain configuration (chain ID, native token, data source) lives in one registry that scanning, graph ingestion, plan gating, and the chain selector UI all read from. Adding a new EVM chain is now a small configuration change, which means we can respond quickly to chain requests going forward.
What we skipped this time
Non-EVM chains like TRON and TON use different address formats and different APIs, so each needs its own scanner implementation. We prioritized the EVM expansion this round, but the registry design extends to non-EVM chains as well — and TRON shipped in August 2026.
Wrapping up
You can now investigate nine chains, Bitcoin included, from a single dashboard. We'll keep broadening coverage — if there's a chain you'd like to see supported, let us know.
