Overview
Moov’s mission is to give developers an easy way to create and integrate bank processing into their own software products. Our open source projects are each focused on solving a single responsibility in financial services and designed around performance, scalability, and ease of use.
Moov Wire implements a reader, writer, and validator for the legacy Fedwire Funds Service message format (FAIM) in an HTTP server and Go library. The HTTP server is available in a Docker image and the Go package github.com/moov-io/wire is available.
Fedwire transitioned to ISO 20022 on July 14, 2025. FAIM is no longer accepted for live Fedwire Funds traffic. For new integrations, use moov-io/wire20022. See What is Fedwire? for details on the cutover.

Purpose
Moov Wire implements a reader, writer, and validator for legacy FAIM Fedwire messages (the proprietary tag-based format from the Fedwire Application Interface Manual). It remains useful for historical files, archival processing, testing, and migration to ISO 20022.
For ISO 20022 Fedwire messages (required on the Fedwire Funds Service as of July 14, 2025):
- moov-io/wire20022 — read, write, and validate Fedwire ISO 20022 XML
- moov-io/fedwire20022 — generated Go types from the Fedwire ISO 20022 XSDs
