Bitcoin vs Ethereum Wallet Screening: Which Goes Deeper?

Ethereum wallet screening traces multi-hop counterparty exposure across the transaction graph; Bitcoin screening only checks the address itself against sanctions and threat lists.

Most compliance tools quietly assume every chain gets the same depth of check. They don't. Of the 780 addresses OFAC has designated across every blockchain it tracks in Plastron's own corpus, 513 sit on Bitcoin and just 97 sit on Ethereum - yet Ethereum is the chain where a wallet screener can actually trace how a flagged address got its funds. Bitcoin's architecture won't let it do the same thing. That's structural, not a product gap.

What's actually different between screening Bitcoin and Ethereum?

Wallet screening means checking an address's history against sanctions lists, mixer contracts, and known-bad clusters before you send or accept funds. On Ethereum and its EVM siblings - Arbitrum, Base, Optimism, Polygon, BNB Chain, Avalanche - that check can walk the transaction graph outward from the address itself, one hop and then another, following counterparty exposure until it hits something sanctioned or stolen. On Bitcoin, the check stops at the address. It gets compared against the OFAC Specially Designated Nationals list and a labelled threat corpus, plus a read of its on-chain balance and activity. No counterparty trace. No multi-hop path. Just a direct hit or a clean result - and even the clean result on Bitcoin carries a confidence score capped at 0.4, well below what an EVM scan can report.

That gap shows up the moment you ask a slightly harder question than "is this exact address on a list." Ask whether a clean Bitcoin address received funds two hops downstream from a ransomware wallet, and today's answer is: not checked. Ask the same question about an Ethereum address, and the scan already walked that path.

Tron sits in the same direct-only lane as Bitcoin, and for a reason that has nothing to do with how well either chain is covered. It's about what the transaction data lets an analyst reconstruct after the fact, not how much attention regulators have paid to the chain. Bitcoin actually carries more OFAC weight than Ethereum, and it still gets the shallower scan. Plastron's OFAC corpus spans 14 chains in total; Bitcoin and Ethereum are just the two largest by designation count.

Head-to-head

Put the two side by side and the gap isn't close. Every category where depth matters - counterparty tracing, hop distance, confidence scoring - splits the same direction. The categories where it doesn't, like sanctions coverage relative to each chain's own footprint, are closer than you'd expect.

Why Bitcoin's clustering trick doesn't work on Ethereum

Bitcoin's transaction format makes clustering almost easy. Every transaction can spend several unspent outputs at once, and the working assumption behind it - the common-input-ownership heuristic - is that whoever supplies every input to one transaction controls all of those addresses. Chain analysts have leaned on that assumption for over a decade. It groups thousands of individually anonymous-looking Bitcoin addresses into single wallets with high confidence. One transaction, one owner. Usually.

Ethereum breaks that assumption completely. It runs on an account model: one address, one balance, updated in place with every transfer. There's no multi-input transaction to analyze, because there's no such thing on Ethereum - each transfer moves from one account straight to another. Analysts studying Ethereum clustering have had to build heuristics from scratch instead: deposit-address reuse, airdrop-claim overlap, token-approval sequences. None of them has become the de facto standard the way common-input-ownership did for Bitcoin.

Deposit-address reuse is the closest thing Ethereum has to a reliable signal, and it only works because exchanges create it by accident. A centralized exchange typically generates one deposit address per customer, then sweeps the balance into a hot wallet on a schedule. Watch enough sweeps land in the same hot wallet from different deposit addresses, and you've clustered a chunk of that exchange's user base without ever touching KYC data. It's a useful heuristic. It's also a byproduct of exchange operations, not a property of the Ethereum protocol itself the way common-input-ownership is a property of how Bitcoin transactions are built.

That imbalance looks backwards until you remember what each number actually measures. Sanctions coverage counts how many addresses a government has named. Screening depth measures how far a tool can trace where funds came from before they reached you. Ethereum's account model and its dense DeFi, bridge, and token-swap activity give a screener more to trace, so a deeper scan pays off there in a way it can't on Bitcoin's comparatively plain UTXO ledger. Plastron's separate known-scam corpus backs that up: 3,901 labelled addresses, and every one of them is on an EVM chain. Bitcoin isn't in it at all.

When a Bitcoin-only check is still enough

Not every check needs a multi-hop trace. If someone hands you a Bitcoin address and you only want to know whether that address itself sits on the OFAC list or a known scam and ransomware corpus, a direct check answers that in one lookup, and answers it just as reliably as a deeper scan would. A direct sanctions hit doesn't get more or less true with extra hops.

Proportionality matters here too. An individual accepting a one-off Bitcoin payment doesn't need the same depth of check as an exchange onboarding thousands of deposits a day. The exchange has regulatory exposure that scales with volume and needs to catch patterns across accounts, not just flag one bad address. A single freelancer or OTC desk just needs to know, before funds move, whether this specific address is radioactive. Direct-only screening answers that question completely, on Bitcoin the same way it does on Ethereum.

You can run that lookup by hand today: pull the address up on a block explorer like mempool.space and cross-reference it against the published OFAC SDN list yourself, entry by entry. Screen a wallet with Plastron instead and it runs the same check in one pass, on both Bitcoin and Ethereum addresses, and shows sanctions, threat-corpus, and balance exposure without the manual lookup.

For that use case, direct-only screening is the right tool, not a downgrade. The downgrade only shows up once you need to know whether a clean-looking Bitcoin address received funds a few hops upstream from tainted coin - and that's a real scenario, not a hypothetical one. The $116 million drained from Coldcard hardware wallets in one firmware exploit is still moving through addresses like that, one clean-looking hop at a time. Solana carries the same direct-only limitation as Bitcoin, and for the same underlying reason - see why Solana screening stays address-only for now too.

Verdict

Ethereum wins on depth, and it isn't close. A wallet screener on Ethereum can walk the graph, price in counterparty risk, and hand back a confidence score that actually means something. Bitcoin's screener hands back a narrower answer: is this specific address flagged, yes or no. For most individual transfers, that narrower answer is exactly what's needed. For anything with material stolen-funds exposure sitting upstream, it isn't, and no amount of clever heuristics closes that gap until Bitcoin gets the same multi-hop tracing Ethereum already has.
