Fiserv DNA is the premium core processing platform within Fiserv's credit union product portfolio. Originally developed as a modern replacement for older Fiserv cores, DNA is built on a relational database architecture with REST API capabilities through the DNA Developer Studio. It serves larger credit unions that need deep configurability and have the IT resources to leverage it.
Fiserv's enterprise core platform for larger credit unions and banks. Aerial is built to integrate directly with Fiserv DNA — your core stays exactly as it is, and your members get a modern account opening experience that converts.
Aerial integrates with Fiserv DNA through the DNA Developer Studio REST APIs. Member records are created or updated, share accounts are opened to the exact product codes configured in DNA, and the full audit trail — including ID verification results and e-signature timestamps — is recorded against the member record. Aerial handles the complete pre-core workflow so that only verified, funded applications hit your DNA environment.
