Sumsub Crypto Monitoring review
Verdict. Crypto wallet and transaction screening inside Sumsub’s identity-verification platform. It does not build its own blockchain data: it runs checks through named analytics providers — Crystal and Merkle Science natively, Chainalysis, Elliptic and TRM Labs with your own contract — and applies your rules to the result. Sold on request to businesses, so it is not scored.
Why it is not scored yet
Our score needs a published price, a confirmed network list and a documented report format. Missing for Sumsub Crypto Monitoring: no published price. Below is how it would do on each criterion with what we could verify.
Missing: no published price, no free check, subscription terms not stated and price list not public.
9 of the 10 core networks are confirmed in its own docs: Bitcoin, Ethereum, TRON, BNB Chain, Polygon, Arbitrum, Solana, Litecoin and XRP Ledger. TON is only claimed elsewhere (half a point each).
Breakdown by risk category and transaction-hash checks. Missing: numeric risk score not verified and PDF report not verified.
Operator named (Sum and Substance Ltd.) and names the analyzers it resells.
No wallet connection — you only paste an address. Missing: account required for the first check.
Available via API and Web.

Is Sumsub legit? Official links and fakes
Sumsub is run by a named company: Sum and Substance Ltd., England (company no. 09688671, per its privacy notice). Our scam vetting of 13 Oct 2026 — operator, regulator lists, security reports, complaints and whether it asks for a wallet connection — found no reports of fraud. Status at our automatic check of 4 Nov 2026: working. Look-alike sites and bots using its name do exist, so open it only from its official website. The real service only needs a public address — anything asking for a seed phrase, a wallet connection or a signature is fake.

FAQ
Where does Sumsub get its blockchain data?
From third-party analytics providers. Its page names Crystal and Merkle Science as native integrations and Chainalysis, Elliptic and TRM Labs as bring-your-own-key options; its docs also list Nominis and CipherOwl.
Can I check a single wallet with Sumsub?
Not as an individual. Crypto monitoring is part of Sumsub’s business platform and is priced on request.
Does Sumsub ask for a seed phrase?
It should not, and a real AML check never needs one — only a public address. Any bot or site using this name that asks for a seed phrase or a wallet connection is fake.
Can Sumsub guarantee my exchange won’t freeze funds?
No service can. Exchanges and stablecoin issuers use their own data and rules. A low score lowers the risk; it is not a guarantee.
