The integrity overlay on the major payment rails.
Visa Direct, Mastercard Send, RTP, FedNow, SWIFT, ACH, SEPA, and the leading stablecoin rails. We do not sit inside the network's authorization path. We sit in front of it, behind it, or alongside it, depending on how the network's existing members want to deploy us.
Talk to network partnershipsPayment networks do not generally absorb third-party APIs into their core authorization flow. The authorization path is sub-second latency, six-nines availability, and tightly scoped. We respect that. We are not asking to be in the authorization path. We are the integrity layer that the network's principals, members, and ecosystem partners call before, after, or alongside authorization.
| Network role | How we integrate |
|---|---|
| Visa principal members and Visa Direct enablers | Pre-authorization integrity check on push payments. Member calls us before initiating Visa Direct. Sanctions / bad-actor hits hard-block before reaching the network. |
| Mastercard principal members and Mastercard Send enablers | Same pattern: pre-initiation integrity check on push transactions. |
| RTP and FedNow originators | Pre-send check at the originating bank or fintech. |
| SWIFT correspondents | Pre-MT103 check at the originating institution. Tier 2 CREB attestation available for high-value or high-risk corridors. |
| ACH ODFIs | Per-debit and per-credit check at the originating institution. Particularly valuable on ACH same-day. |
| SEPA SCT and SCT Inst | Pre-send check at the originating PSP. PSD2 SCA flow unaffected. |
| Stablecoin rails (USDC, EURC, others) | On-chain integrity check before signing the transfer transaction. |
| Card networks broadly | Acquirer-side per-merchant per-transaction check on inbound card volume. Issuer-side per-cardholder per-transaction check on outbound card volume. |
Every major payment network is under continuous pressure from fraud loss, sanctions enforcement, and cross-border compliance. The networks themselves are regulated entities. Their members are regulated entities. The members' end-customers are increasingly under scrutiny. The traditional answer (each member runs its own fraud and compliance stack, often built in-house, often inconsistent across the network) leaves obvious gaps.
Attestyx offers networks a way to bless a default integrity layer that any member can deploy with a single API integration, that produces consistent signal quality across the network, and that contributes back to a cross-network bad-actor registry that compounds the value of network-wide deployment.
