Moov Wire implements a reader, writer, and validator for the legacy FAIM Fedwire Funds message format (Fedwire Application Interface Manual) in an HTTP server and Go library.
The Fedwire Funds Service transitioned to ISO 20022 on July 14, 2025. FAIM is no longer accepted for live traffic. For new integrations, use moov-io/wire20022. This project remains available for historical FAIM files, testing, and migration.
