}A real decision on the Ronin bridge exploit address that OFAC attributes to the Lazarus Group. Public record; the source link opens the SDN entry.
One POST with the subject. The response above comes back in tens of milliseconds for addresses; exposure runs inside a budget and never blocks the answer.

}'Apps that move money, including crypto apps, are required to make sure they are not dealing with sanctioned people, companies or wallets. Clearlist does that check for them, instantly, and keeps the proof.
Before a user signs up or money moves, the app sends us one thing to check: a wallet address, a person's name, a country, or a whole transaction.
Every official government sanctions list (US, EU, UK, UN), public records of hacker, mixer and scam wallets, and who that wallet has actually transacted with.
In well under a second: allow, review, or block. With the reason in plain English and the evidence attached, so you can show it to a user, a bank, or a regulator.
Nothing matched. The app lets the sign-up or payment through. This is the answer for almost everyone.
Something looks like a match but is not certain, for example a common name. A human takes a look; one click clears or confirms it.
A definite match: a listed wallet, or a name confirmed by a date of birth or ID. The app stops the transaction and has the record to prove why.
Crypto wallets, stablecoin payment apps, exchanges, cash-in and cash-out ramps, marketplaces, launchpads, fintechs adding crypto, and new blockchains that want every app in their ecosystem covered from day one. Anyone whose bank or partner is about to ask “what do you do about sanctions?”
Want to send this to someone? The plain-English page stands on its own.
Sign up, get a key, make the first call. Public pricing, a free tier, and no discovery call. Five minutes is the whole onboarding.
Every decision is allow, review or block, with a list of reasons. Each reason has a one-sentence summary and the evidence behind it: which list, which entry, which batch, which counterparty, which hop. No risk scores to interpret.
A policy you edit, an allowlist you own, and a review queue with one-click clear or confirm. A name alone never blocks; it needs a corroborating identifier.
Decisions are append-only and record the exact list versions used. Export the evidence file for any decision, or print the attestation that describes your program.
Solana and the EVM family get the full treatment: lists, labels and who the wallet has transacted with. Every other chain is screened against the government lists the day an address is listed. A new chain can be added the week it launches. Foundations can sponsor coverage for every app in their ecosystem; see pricing. The registry is public at GET /api/v1/chains.
Is this exact address on a government sanctions list, or in a public label set for mixers, hacks, scams, darknet markets and ransomware? Designated addresses are strings, so this works on any chain, including ones that launched yesterday. Government lists are matched on every chain; public labels are matched on the chains where a label source exists.
Who has this address transacted with? One hop today, two hops reported as information. Runs on Solana through Helius or any Solana RPC, and on every Etherscan-indexed EVM chain, from Ethereum, Base, BNB Chain and Robinhood Chain to Monad and HyperEVM, through the Etherscan v2 API. Bitcoin, Tron, the UTXO chains, Monero and XRP are screening-only for now; exposure arrives as providers are added.

Six kinds of team, each with a moment when screening stops being optional. What they screen and which parts of Clearlist carry the load.
Ecosystem sponsorship is available now; the on-chain oracle is built and tested, with testnet deployment pending.
Early. The API works for this today; the integration patterns are still being written with the first platforms.
Not sure which plan? Plan guidance by segment.
Sanctions screening used to be a problem for banks and large exchanges. Five things changed, and now a wallet with a thousand users is asked the same questions.
Chainalysis, Elliptic and TRM are excellent investigation products sold to compliance teams through enterprise contracts. Name-screening APIs cover people, not wallets. Clearlist is the decision layer for a developer who has to ship screening this week. Full comparison.
| Clearlist | Chainalysis, Elliptic, TRM | Name-screening APIs | |
|---|---|---|---|
| How you buy | Sign up, create a key, call the API. No sales call. | Sales-led. A call, a quote, a contract. | Mostly sales-led; some offer self-serve starter plans. |
| Pricing visibility | Public. Free trial, then $299 or $1,500 a month. Foundation and Enterprise from $50,000 a year. | Not published. Quote-based enterprise contracts. | Varies; usually quote-based above a starter tier. |
| Minimum commitment | None on self-serve tiers: month to month, cancel any time. Annual billing is optional. Foundation and Enterprise are annual agreements. | Annual enterprise contracts are typical. | Usually an annual contract above a starter tier. |
| Time to first screen | Minutes. The curl in the docs works with a test key. | Weeks: procurement, contract, onboarding, integration. | Days to weeks. |
| What a decision looks like | allow, review or block, with a list of reasons. Each reason has a one-sentence summary and the evidence behind it. Plus a user_message you can show your end user. | A risk score or risk level with a category label. The why lives in the investigation product. | Match score per name with the matched list entry. No chain context. |
| False-positive controls | Your policy (thresholds and actions per category), your allowlist, a review queue with one-click clear or confirm. A name never blocks on its own. | Alert rules configured inside the platform; tuning is an account-management conversation. | Fuzzy-match thresholds; whitelisting varies by vendor. |
| Evidence export and attestation | A per-decision evidence file (the decision plus the complete list records and batch versions behind it), a printable attestation page with a share link, and a Compliance Pack (policy, risk assessment, procedure) generated from your real configuration. | Reports and case exports from the investigation product. | Match reports and audit logs. |
| Exposure depth | One hop today, two hops reported as information. Growing. Honest limit: this is where they are stronger. | Deep multi-hop attribution graphs. This is their core strength. | None. |
| Chain coverage | 45 chains screened, 32 EVM. Exposure on 32. A new chain is added the week it launches; the registry is public. | Broad, Ethereum-first. New chains arrive on a roadmap, often months after launch. | No chain coverage. |
| Investigations tooling | None. Clearlist answers the question at the point of decision; it is not a graph explorer. | Excellent. Graph exploration, clustering, case management. | None. |
Vendor descriptions are general; their pricing is not published. Where they are stronger (attribution depth, investigations, SOC 2) the full comparison says so.
OFAC SDN and Consolidated, EU Financial Sanctions, UK OFSI, and the UN Security Council list, fetched from the publishers and versioned as batches. Public chain labels for mixers, hacks, scams, darknet markets and ransomware. Every entry carries its source URL. No resold third-party datasets with non-commercial terms.
Counterparty exposure runs on Solana, through Helius or any Solana RPC, and on all 32 EVM chains in the registry, from Ethereum, Base, BNB Chain and Robinhood Chain to Monad and HyperEVM, through one Etherscan v2 integration. Address screening against the government lists works on every chain because designated addresses are strings: Bitcoin, Tron, the UTXO chains, XRP and Monero are covered the day an address is listed. A new L1 or L2 can be added the week it launches, and a foundation can sponsor every app on it.
Sign up, copy your key, paste the curl. The dashboard shows the decision with its evidence.
