# Open-source contributions

> A minimal reference dApp Compass open-sourced for the Arc developer ecosystem.

> Alongside Compass, the team maintains a small open-source reference dApp called `arc-cross-yield-agent`. It is a separate, much simpler project — useful for Arc developers exploring Circle Gateway and same-address CREATE2 patterns. It is not the Compass product.

## What it is

[`arc-cross-yield-agent`](https://github.com/compassailabs/arc-cross-yield-agent)
is a deliberately minimal reference implementation of an AI-driven
cross-chain USDC flow on Arc. It demonstrates a few primitives Arc
developers can fork:

* Circle Gateway integration for sub-second cross-chain settlement.
* Same-address smart accounts across chains via CREATE2.
* USDC-as-gas on Arc, with no paymaster.

That's the scope. It sits in the same family as other Arc reference dApps
like `arc-commerce` and `arc-p2p-payments` — fork-friendly, opinionated
about one thing, and small enough to read in an afternoon.

## What it is not

`arc-cross-yield-agent` does **not** include the parts that make Compass a
real product:

* No Diamond account architecture.
* No session keys or on-chain policy enforcement.
* No deterministic evaluator or chat agent.
* No audit trail.

Those live in Compass. If you came here looking for how Compass is built,
the rest of this documentation is the right place.
