asked questions ### How does Sardine verify bank account ownership in real-time? Sardine verifies bank account ownership by correlating account data with identity, device, and behavioral signals in real-time. This confirms whether an account belongs to the intended user and that it’s eligible for ACH transactions before funds move. ### What types of bank account risk can Sardine detect? Sardine detects risks such as mule accounts, reused or shared bank details, unauthorized account changes, and compromised credentials. By linking bank data to behavioral and network context, the platform detects both direct and indirect risk before funding, payouts, or payments occur. ### How does Sardine reduce ACH returns and payment losses? Sardine assesses account status, ownership confidence, and predicted return risk before ACH is initiated. This helps prevent non-sufficient funds, unauthorized debits, and payment diversion by stopping high-risk transactions pre-settlement rather than reacting after losses occur. ### Does Sardine support coverage beyond traditional bank datasets? Yes. Sardine waterfalls across multiple providers and its Sonar consortium to expand coverage for small banks, sponsor banks, and fintech-issued accounts. This ensures verification and risk insights even when accounts aren’t present in traditional datasets. ### How are bank verification decisions made explainable and auditable? Every bank verification decision includes clear evidence showing which signals influenced approval, holds, or escalations. Sardine maintains audit-ready records tying bank data, risk signals, and reviewer actions together to support Nacha requirements and regulatory reviews.
