Payments

Grow your merchant base without growing your risk

Every good merchant you slow down or reject is lost volume. Every bad one you approve is a loss or a scheme penalty. Sardine helps you onboard merchants others can't and catch risk as it changes.

illo

One platform for merchant risk

Underwriting, monitoring, and payment risk share one record, so what you learn at onboarding improves every later decision.

illo

Network Intelligence beyond your portfolio

Shared signals across merchants, devices, and entities fill gaps in your own data, so even new merchants with no history get a confident decision.

Expose shell sites and linked merchants

Link merchants, domains, devices, and cards to expose shell sites and related merchants tied to violations.

illo

Automate merchant research

Agents research each business, check declared MCCs against what it sells, and flag what needs review, so KYB moves faster with every step recorded.

Manage merchant risk from application to settlement

Merchant underwriting

Approve more of the merchants you want

Combine KYB, website presence, and acquiring data with device and behavior signals to onboard new merchant types and verticals with confidence.

Merchant underwriting
icon
Verify the business

Run KYB checks 90% faster across 450+ sources in 195 countries.

icon
Set thresholds by merchant type

Configure rules and workflows by risk tier, industry, geography, or card-network requirements.

Merchant monitoring

Merchant monitoring

Know when a good merchant starts looking different

Approval is only the start. Sardine catches sudden growth, behavioral shifts, and deterioration before they result in losses.

Merchant fraud protection

Protect every merchant from payment fraud

Merchants count on their payment provider to catch fraud, and smaller ones have no team of their own. Sardine scores every payment and links attacks across your whole portfolio.

Merchant fraud protection
icon
Stop bad payments

Score every payment in real time using identity, device, behavior, and transaction history.

icon
Catch coordinated attacks

Investigate shared devices, IPs, emails, and cards linked to coordinated abuse across merchants.

icon
Fit protection to every merchant

Set rules by merchant segment, so smaller merchants are covered without a fraud team.

Compliance and scheme risk

Compliance and scheme risk

Keep merchant risk from becoming regulatory and scheme exposure

Risky merchants push your portfolio past card-network thresholds, which brings added controls like 3D Secure, fees, and lower approval rates.
