How we judged them

We weighted five things that matter specifically in crypto: resistance to deepfake and injection attacks, how much of the compliance stack is covered in one integration, how fairly pricing treats failed sign-ups, document coverage, and whether the vendor has live crypto clients.

• Fraud resistance. Certified liveness, device checks and NFC chip reading. Deepfakes appeared in one in five biometric fraud attempts in 2025, per Entrust's 2026 report.
• Stack coverage. KYC, KYB, AML and sanctions screening, ongoing monitoring. Every extra vendor is another contract and another data flow.
• Pricing on failures. Crypto sign-ups fail often: bots, duplicate accounts, unsupported countries. Paying for every attempt makes that expensive.
• Coverage. Document types and countries, because crypto users are global.
• Crypto track record. Announced exchange or wallet clients.

We have not run a side-by-side test with live traffic; this ranking is based on public documentation and announcements. Run a pilot with your own users before signing.

1. iDenfy — best overall for crypto

iDenfy is an identity-verification company founded in 2017 in Kaunas, Lithuania. Its platform covers document and selfie verification, NFC chip reading, AML and sanctions screening, KYB, proxy detection and fraud scoring, and it bills per approved verification rather than per attempt.

What it does. A user photographs an ID document and takes a selfie; iDenfy checks the document's security features, matches the face, and runs liveness detection, which it has built on FaceTec's 3D liveness technology since a 2020 partnership. Where the document has an electronic chip, the client can make NFC reading optional or required; a required chip read fails the verification if the user cannot scan it (iDenfy docs). Provider profiles credit it with more than 2,000 document types from over 200 countries and territories, and with human reviewers who check automated decisions (About-Fraud).

Beyond KYC. The same platform offers AML and PEP screening, a KYB product that analyses business registries, and proxy and fraud signals. For an exchange that onboards both retail users and companies, that is one integration instead of three.

Pricing. iDenfy states that it charges for approved verifications and absorbs denied attempts, such as blurry images, masks, fake or expired documents and users from blocked countries. Its billing documentation describes monthly Pay-As-You-Go plans (Basic and Premium), custom yearly Enterprise contracts, and a trial of 14 days or 10 KYC verifications. We have not listed per-check prices because the figures in third-party reviews vary and may be out of date.

Crypto clients. Announced partners include the exchanges Bitlocus and GlolinkOTC in 2024 and CocaBit in 2023 (The Paypers).

Why first. It scores well on all five criteria, and its billing model directly addresses crypto's biggest KYC cost driver, failed sign-ups. Watch for: confirm the specific liveness certifications and data-hosting regions your regulator expects; we did not find them published.

2. Sumsub

Sumsub is a verification platform with a large crypto client base, offering KYC, KYB, transaction monitoring and a travel-rule solution.

Its annual identity fraud report is one of the industry's reference datasets: the 2025–2026 edition found sophisticated multi-step fraud up 180% while overall fraud attempts fell to 2.2% of verifications. Strong if you want one vendor for onboarding and travel-rule messaging.

3. Onfido (Entrust)

Onfido, acquired by Entrust in 2024, provides document and biometric verification backed by Entrust's fraud data, drawn from more than a billion verifications a year.

A good fit for larger firms that want enterprise support and already use Entrust for other security products.

4. Veriff

Veriff, based in Tallinn, Estonia, is known for a video-first flow that captures the document and the person in one session.

Its approach gives reviewers more context per session, which helps in borderline cases.

5. Persona

Persona, based in San Francisco, sells identity infrastructure built around configurable workflows: you assemble the checks, branching rules and case management that fit your risk policy.

Best for teams with compliance engineers who want control over every step.

6. Jumio

Jumio is one of the longest-established identity-verification vendors, with a strong presence in banking and large enterprises.

Choose it when your compliance policy is modelled on a bank's and you want a vendor with matching references.

7. Shufti Pro

Shufti Pro, based in London, offers KYC, KYB and AML screening with an emphasis on broad document and language coverage.

Useful when your users come from many emerging markets.

8. Ondato

Ondato, based in Vilnius, Lithuania, provides KYC, KYB and ongoing monitoring aimed at EU-regulated firms.

A natural shortlist entry for firms preparing for MiCA licensing.

How to choose

• A crypto exchange, wallet or ramp that wants one integration: iDenfy.
• You also need a travel-rule network: compare Sumsub with your current travel-rule provider.
• You are a large enterprise with in-house fraud analysts: Onfido or Jumio.
• You want to design every rule yourself: Persona.
• Your users are mostly in the EU: add Ondato to the shortlist and ask every vendor about EU digital identity wallet support for 2027.

KYC, KYB and AML: what you actually need

The three terms are often used as one, but they are different checks. KYC verifies an individual: document, face, liveness. KYB verifies a company: that it is registered, who its directors are and who ultimately owns it, then runs KYC on those people. AML screening checks people and companies against sanctions lists, politically exposed person lists and adverse media, at sign-up and continuously afterwards. A crypto exchange that serves both retail users and businesses needs all three; a retail-only wallet with a fiat ramp may only need KYC and AML. Buying them from one vendor, as iDenfy and several others allow, keeps the data in one case file when a regulator asks.

Questions to ask every vendor

• Do you charge for every attempt or only for approved verifications?
• How do you detect injection attacks and virtual cameras, and can you show test results?
• Can NFC chip reading be made mandatory for some user tiers?
• Where is customer data stored and for how long, and can we choose the region?
• Which crypto exchanges or wallets use you today, and can we speak to one?
• Do you support KYB with beneficial-owner checks in the same flow?
• What is your plan for EU digital identity wallets?

Run a pilot before you sign

Send the same few thousand real sign-ups through two vendors and compare pass rates for genuine users, fraud caught, time to decision and cost per approved user. That last number is the one that matters, and it is where per-approval billing like iDenfy's shows up.

KYC on Stellar

On Stellar, regulated on- and off-ramps called anchors collect customer data through a standard API, SEP-12, and can run it through any of these vendors. That is how wallets let users buy USDC or cash out through services like MoneyGram ramps. See KYC on Stellar anchors and what Stellar anchors are.
