# Onchain Execution Service APIs

This family covers onchain execution workflows where transaction propagation, network behavior, and routing are the primary integration concerns.

## [API Reference](#api-reference)

Browse the interactive OpenAPI reference for the Onchain Execution Service APIs — endpoints, request and response schemas, authentication, and in-browser “Try it” — in the [API catalog](https://docs.api.galaxy.com/apis).

## [Persona and Operating Context](#persona-and-operating-context)

Primary personas:

-   Execution and automation teams
-   Wallet and treasury engineering teams
-   Platform teams that submit or monitor onchain transactions

Operating assumptions:

-   Network-aware transaction handling
-   Low-latency execution and propagation behavior
-   Event-driven confirmation and reconciliation

## [Platform Background From the DDQ](#platform-background-from-the-ddq)

The DDQ does not focus heavily on this family, but it does reinforce the platform's security and operational posture: continuous monitoring, SOC 2 Type 2 reporting, least-privilege access, and regulated controls around transaction handling and asset safety.

The DDQ also notes that Galaxy is building out live onchain transaction monitoring via TRM Labs, which fits the operational concerns of this family.

## [Family Navigation](#family-navigation)

-   Coming Soon

## [Family Summary](#family-summary)

Use this family when your integration depends on onchain execution semantics instead of account-centric or order-centric workflow behavior.

Because the DDQ is light on direct onchain-execution detail, the family should remain conservative and avoid overclaiming specific chain support or execution semantics until the product documentation says so.

## [Shared Mechanics](#shared-mechanics)

If a behavior is identical across families, it can remain linked from the shared guides until the Onchain Execution Service-specific differences are finalized.
