What happened

RockWallet / MNEE App, a U.S. crypto and fiat payments platform, uses Sardine's device intelligence, behavioral biometrics, rules-based scoring and sanctions screening to prevent fraud, block bot attacks and keep chargebacks below its contractual limit.

Summary written by usedby from the source page, in English. The figures are those of Sardine and RockWallet, not ours.

  • 23,000“Over 23,000 fraudulent account signups were blocked during a single coordinated bot attack”
  • 40 days“New fraud rules are backtested across 40 days of live ACH data before deployment, achieving approximately 90% rule precision.”
  • 6,000“These checkpoints analyze over 6,000 risk signals, including behavioral biometrics that detect guided mouse movements or the use of remote access tools.”

Through tailored risk rules aligned to business needs, chargeback activity was reduced by approximately 35% year-over-year, with the chargeback rate maintained well below the 1% threshold throughout the period.

The device data is extremely handy. The fraud attack started with us picking up device spikes. Then we started diving deeper and deeper with Sardine and were able to find something else happening.
